Design documents, PRDs, and architectural specifications for Morphir .NET
This section contains design documentation for Morphir .NET, including AI Skill Framework architecture, Product Requirements Documents, and architectural decision records.
AI Skill Framework
The morphir-dotnet project uses a sophisticated AI skill framework (gurus) for cross-agent development assistance:
Review Capability: Every guru includes proactive review capability
Cross-Agent Design: Ensure portability across Claude, Copilot, Cursor, and other agents
Retrospective Integration: Plan for continuous improvement through feedback loops
1.1 - AI Skill Framework Design
Design for unified, cross-agent AI skill architecture (gurus)
AI Skill Framework Design
Overview
This document establishes a comprehensive, scalable architecture for AI skills (known as “gurus” in this project) that work seamlessly across Claude Code, GitHub Copilot, and other coding agents. The goal is to create a repeatable pattern for developing specialized AI team members who improve continuously and provide expert guidance in specific domains.
Motivation
The morphir-dotnet project has implemented three sophisticated gurus (QA Tester, AOT Guru, Release Manager) that provide specialized expertise through:
Decision trees for problem-solving
Automation scripts (F#) for repetitive tasks
Playbooks for complex workflows
Templates for common scenarios
Pattern catalogs of domain knowledge
As the project plans to add more gurus (Elm-to-F# Guru, Documentation Guru, Security Guru, etc.), we need:
A clear definition of what makes a guru
Repeatable patterns for creation
Cross-agent accessibility (not Claude-only)
Continuous improvement mechanisms
Cross-project reuse strategy
What is a Guru?
A guru is not a tool or a prompt. It’s a knowledge stewardship system with these characteristics:
mindmap
root((Guru))
Stewardship
Owns a domain
Accountable for quality
Quality gate
Continuous Improvement
Learns from interactions
Quarterly reviews
Feedback loops
Proactive Review
Scans for issues
Detects problems early
Captures patterns
Automation-First
F# scripts
Reduces token cost
Improves with scale
Collaboration
Clear hand-offs
Escalation paths
Shared patterns
Stewardship
Owns a domain (Quality, Optimization, Releases, Migration, etc.)
Accountable for quality, velocity, and responsibility in that domain
Maintains and evolves best practices and decision frameworks
Acts as a quality gate preventing regressions and anti-patterns
Continuous Improvement
Learns from interactions - Every session captures patterns and discoveries
Feeds back into guidance - Playbooks, templates, and catalogs evolve
Release Manager → Could adapt for mono-repo versioning (CHANGELOG format may differ)
Elm-to-F# Guru → Pattern catalog portable, IR-specific knowledge less so
Reuse Checklist
When planning to use a guru in a new project:
Understand skill’s domain and scope
Assess project-specific config needs
Identify paths/repos that need adjustment
Read “Adapt to New Project” section in skill README
Test skill with sample scenario
Document adaptations (if any)
Report improvements back to origin project
Example: QA Tester in morphir-elm
Original (.morphir-dotnet): `.claude/skills/qa-tester/`
├── skill.md - Core QA philosophy, no project-specific content
├── README.md - Scripts references can be adapted
└── scripts/
├── smoke-test.fsx - Paths would need adjustment
├── regression-test.fsx - Test command would change
└── validate-packages.fsx - Package names would differ
Adapted (.morphir-elm):
├── Test: npm run test vs. dotnet test
├── Smoke: npm run build vs. dotnet build
├── Packages: npm packages vs. NuGet packages
├── Regression: Same BDD/TDD philosophy, different tech stack
Effort: 2-4 hours to adapt and test

1.2 - Guru Philosophy
The collaborative AI stewardship philosophy behind morphir-dotnet gurus
Guru Philosophy
The Core Concept
A guru is not a tool. It’s not a utility function or a helpful prompt. A guru is a knowledge stewardship system—a specialized AI team member who owns a domain, improves continuously, and acts as a collaborative partner in advancing project health, maintainability, and velocity.

style L fill:#c8e6c9
style K fill:#c8e6c9
style G fill:#c8e6c9
This philosophy distinguishes morphir-dotnet’s approach to AI collaboration from the typical “ask the AI for help with X” pattern.
The Guru is Not…
Not a Tool
❌ Tools are static; gurus evolve
❌ Tools answer one question; gurus build knowledge systems
❌ Tools don’t improve themselves; gurus have feedback loops
✅ Gurus capture patterns and feed them back into guidance
Process Steward (Release Manager) - Ensures releases are reliable and predictable
Migration Steward (Elm-to-F# Guru) - Preserves fidelity and quality in cross-language migration
What stewardship means:
Accountable for quality in the domain
Proactive, not reactive (“What problems can I prevent?”)
Maintains best practices and decision frameworks
Improves gradually, with intention
A Learning System
A guru improves over time through automated feedback:

B -->|No| D[Apply Existing<br/>Patterns]

end
style A fill:#e3f2fd

style E fill:#c8e6c9
style I fill:#fff9c4
style K fill:#c8e6c9
Release Manager Example (Proof):
After every release failure → Automated retrospective captures “What went wrong?” and “How to prevent?”
After 3+ consecutive successes → Prompts for improvement ideas
When release procedures change → Detects and prompts playbook updates
Result: Release playbooks evolve each quarter, getting smarter
Elm-to-F# Guru Example (Planned):
Every migration discovers new Elm-to-F# patterns
Patterns repeated 3+ times trigger “Create Myriad plugin?” decision
Philosophy: “Every high-token task automated is a permanent improvement.”
A Collaborator
A guru coordinates transparently with other gurus:
sequenceDiagram
participant ELM as Elm-to-F# Guru
participant AOT as AOT Guru
participant QA as QA Tester
participant RM as Release Manager
ELM->>AOT: Generated code for review
Note over AOT: Verify AOT compatibility
AOT-->>ELM: ✓ AOT-safe + suggestions
ELM->>ELM: Apply recommendations
ELM->>QA: Code ready for testing
Note over QA: Run test suite
QA-->>ELM: ✓ Coverage 85%
ELM->>RM: Feature complete
Note over RM: Include in release
RM-->>ELM: ✓ Scheduled for v1.2.0
Collaboration principles:
Explicit hand-offs at domain boundaries
Clear communication of status and constraints
Escalation paths when uncertain
Mutual respect for expertise
A Reviewer
A guru proactively reviews the codebase and ecosystem for quality, adherence to principles, and opportunities:
Create automation scripts (F# for high-token work)
Build pattern catalog
Design templates
Phase 3: Learning Integration
Implement feedback capture
Establish review schedule
Design playbook evolution
Document improvement process
Phase 4: Review Implementation
Design review scope and criteria
Create review scripts/tooling
Establish review schedule and cadence
Design integration with playbooks and automation
Phase 5: Collaboration
Coordinate with other gurus
Test hand-offs
Verify escalation paths
Validate error handling
Phase 6: Teaching
Create decision trees
Document patterns
Write playbooks
Provide templates
Guiding Principles
1. Learn From Every Session
A guru that doesn’t improve is just a prompt.
Every session with a guru should feed insights back into its knowledge system. New patterns, edge cases, failures—all become part of the playbook.
2. Review Proactively
A guru that only reacts to problems is incomplete.
Gurus should scan their domain regularly for issues, guideline violations, and improvement opportunities. Reviews are how gurus stay engaged and make their presence felt. Combine review findings with retrospectives to create continuous improvement loops.
Review ≠ One-Off Code Review:
Code review is reactive (“Please review my PR”)
Guru review is proactive (“I scanned the project and found these issues”)
Code review gives feedback once
Guru review captures findings to improve guidance
3. Automate Repetitive Work
Token efficiency is a feature, not an afterthought.
Identify high-token-cost repetitive work and create scripts to automate it. This makes the guru more efficient and the entire project benefit from permanent automation.
4. Document Why, Not Just What
Teaching is as important as doing.
When a guru provides guidance, it should explain the reasoning, not just the answer. This teaches users to make better decisions independently.
5. Collaborate Transparently
Gurus are team members, not black boxes.
Clear hand-offs, explicit coordination, and honest escalation build trust and effectiveness across the guru team.
6. Respect Scope Boundaries
A guru should escalate gracefully when uncertain.
Gurus should know their limits and escalate decisions beyond their scope. This prevents over-confident guidance in unfamiliar territory.
7. Improve Continuously
Quarterly reviews are non-negotiable.
Regular retrospectives, proactive reviews, feedback capture, and playbook updates ensure gurus don’t ossify. A guru that never evolves is essentially deprecated.
The Vision
Imagine a morphir-dotnet project where:
Quality is maintained automatically through QA Tester’s standards
AOT goals are pursued pragmatically via AOT Guru’s guidance
Releases are reliable and predictable thanks to Release Manager’s playbooks
Elm-to-F# migration proceeds smoothly with Elm-to-F# Guru’s expertise
New domains are stewarded by additional gurus built using proven patterns
Every guru improves every quarter through automated feedback
Every guru automates high-token work so humans focus on decisions
Every guru collaborates gracefully with clear hand-offs
Knowledge is preserved and evolved organically through use
This is not a future state. It’s what morphir-dotnet is building now.

1.3 - IR Classic Migration and Namespace Strategy
Design guide for Morphir.IR.Classic namespace strategy and migration from morphir-elm
IR Classic Migration and Namespace Strategy
Overview
This document describes the namespace strategy for Morphir IR in the F# implementation, specifically the separation between Morphir.IR.Classic (existing morphir-elm IR) and Morphir.IR (future evolution). This guide serves as a reference for AI agents and human contributors working on the Morphir IR model.
Purpose
The Morphir maintainers recognize that the generic attribute approach in the current IR complicates things, but we need to support existing morphir-elm tools and enable migration of existing code. The namespace strategy allows us to:
Support existing tools: Maintain compatibility with morphir-elm ecosystem
Enable migration: Allow existing morphir-elm code to migrate to F# (and eventually other languages)
Reserve evolution space: Keep Morphir.IR namespace free for future improvements
Document decisions: Provide clear guidance for contributors and AI agents
Namespace Strategy
Morphir.IR.Classic
Purpose: Represents the existing IR available in morphir-elm with generic attributes.
Strategy: Support existing tools while reserving space for future improvements
Migration: Enable morphir-elm → F# migration while planning for future evolution
1.4 - Guru Creation Guide
Step-by-step guide for creating new AI gurus in morphir-dotnet
Guru Creation Guide
Overview
This guide walks through the process of creating a new guru (AI skill) in morphir-dotnet. It establishes a repeatable pattern that ensures consistency, quality, and alignment with the guru philosophy.
A guru should be created when you have a domain of expertise that:
Is distinct and has clear boundaries
Crosses multiple project areas or is deep within one area
Has 3+ core competencies (expertise areas)
Contains repetitive work suitable for automation
Part 1: Should This Be a Guru?
Decision Framework
Use this flowchart to determine if you should create a guru:
Isolated domain (could be .agents/ guide or standalone skill)
Decision Result
If all 5 questions are YES → Create a guru skill
If any are NO → Consider alternatives:
Just 1-2 competencies? → Create .agents/{topic}.md guide instead
No automation opportunity? → Document decision trees in AGENTS.md
No coordination needed? → Create standalone utility or guide
Too narrow/specific? → Create template or plugin, not full guru
Part 2: Guru Definition
Step 1: Define the Domain
Write a clear 2-3 sentence description:
Domain: Release Management
Description: Orchestrating the complete release lifecycle from version planning
through deployment and verification. Ensures releases are reliable, predictable,
and recoverable.
Step 2: Define Competencies
List primary and secondary competencies:
Primary Competencies (3-6 core areas):
Version Management - Semantic versioning, version detection
Changelog Management - Keep a Changelog format, parsing, generation
Deployment Orchestration - Workflow automation, status tracking
Release Manager Responsibilities:
- Ensure releases happen on schedule without surprises
- Prevent release failures through pre-flight validation
- Enable fast recovery if failures occur
- Improve the release process continuously (quarterly reviews)
- Communicate clearly about status and blockers
- Coordinate with QA on verification and AOT Guru on version compatibility
Step 4: Define Scope Boundaries
What is explicitly NOT this guru’s responsibility?
Release Manager Does NOT:
- Make product decisions about what features to include
- Review code quality (that's QA Tester's job)
- Decide version numbering policies (that's maintainers' decision)
- Handle security issues (that's future Security Guru's job)
- Manage documentation (that's future Documentation Guru's job)
Step 5: Map Coordination Points
Identify other gurus this will coordinate with:
Release Manager Coordination:
- WITH QA Tester: Hand-off after release for verification
- Trigger: Release deployed
- Signal: "Ready for post-release QA?"
- Response: Test results, coverage, functional verification
- WITH AOT Guru: Verify version tags are AOT-compatible
- Trigger: Before publishing release
- Signal: "Can I publish this version?"
- Response: AOT status, any breaking changes
- WITH Elm-to-F# Guru: Track feature parity milestones
- Trigger: Migration progress updates
- Signal: "What's our migration status for this release?"
- Response: Completed modules, parity progress

Part 4: Automation Strategy
Identify High-Token-Cost Tasks
For your guru domain, identify 5-10 repetitive tasks:
Release Manager Example:
Check GitHub Actions status (manual every 5 min = many tokens)
Validate post-release status (manual testing = tokens)
Extract release history for notes (manual searching = tokens)
Detect process changes (manual review = tokens)
Prioritize for Automation
Score tasks on:
Frequency: How often does this happen? (1-5 scale)
Token Cost: How many tokens does it cost? (1-5 scale)
Repetitiveness: Is this the same every time? (1-5 scale)
Task Frequency Token Cost Repetitive Priority
Monitor release status 5 (every few min) 3 5 Critical
Prepare checklist 3 (per release) 2 5 High
Post-release validation 3 (per release) 3 5 High
Extract release history 2 (per release) 2 3 Medium
Detect process changes 1 (quarterly) 2 4 Medium
Select top 3-5 for automation
Design Automation Scripts
For each task, design an F# script:
Script Design Pattern:
Input: What data does this need?
Processing: What analysis/transformation?
Output: What does it return?
Token Savings: How much does this save?
Example: Monitor Release Status
Input: GitHub Action workflow ID
Processing: Poll GitHub Actions API, track status
Output: Current status, elapsed time, next check
Token Savings: 100+ tokens per hour (vs. manual polling)
Capture Trigger: After each module migration
Capture Method: Migration template includes "Patterns Discovered" section
Review Schedule: Quarterly pattern inventory review
Improvement Action: If pattern appears 3+ times, create Myriad plugin
Q1: Discovered 15 new patterns
Q2: Created 2 Myriad plugins for repetitive patterns
Q3: Updated decision trees based on learnings
Q4: Plan next quarter's automation
Design Review Process
Define quarterly reviews:
Collect: Gather all feedback from past quarter
Analyze: Identify 2-3 key improvements
Decide: What will change? What won’t?
Update: Modify playbooks, templates, patterns
Document: Record what changed and why
Communicate: Let users know about improvements
Review Checklist:
Feedback reviewed (N items)
Improvement areas identified (3-5 topics)
Playbooks updated (X changes)
Patterns added/modified (Y patterns)
Automation opportunities identified (Z scripts to create)
Version bumped if user-facing changes
Part 5B: Review Capability
Design the Review Scope
A guru should proactively review its domain for issues, guideline violations, and improvement opportunities.
To playbooks: “We found 3 reflection patterns, add to decision tree”
To automation: “This pattern appears repeatedly, create detection script”
To retrospectives: “Q1 findings suggest process changes”
To next review criteria: “Focus on this area going forward”
Create Review Scripts
Design and implement F# scripts that perform reviews:
Example: AOT Guru’s Quarterly Review
// scripts/aot-scan.fsx - Quarterly review of all projects
// Scans for:
// - Reflection usage (IL2026 patterns)
// - Binary sizes vs. targets
// - Trimming-unfriendly patterns (static fields, etc.)
//
// Output: Markdown report with findings, trends, recommendations
Findings:- Reflection in 7 locations (5 in serialization, 2 in codegen)- Binary sizes: 8.2 MB (target 8 MB)- creeping by ~200 KB/quarter
- New pattern: ValueTuple boxing in LINQ chains (appears 3x)- Opportunities: 2 patterns ready for Myriad plugin automation
Recommendations:- Create aot-serializer.fsx (Myriad plugin)for serialization reflection
- Add ValueTuple boxing detection to aot-diagnostics.fsx
- Set size limit at 8.5 MB (buffer)or refactor
Next Quarter Focus:- Monitor ValueTuple pattern frequency
- Implement Myriad plugin if pattern appears >5 more times
- Evaluate serialization library alternatives
Integrate Review with Retrospectives
Design how reviews and retrospectives work together:
Review (Proactive):
"I scanned the code and found these issues"
└─ Findings feed into retrospectives
Retrospective (Reactive):
"That failure happened because of X"
└─ Root cause feeds into reviews: "Start looking for X pattern"
Together: Continuous improvement cycle
Findings → Prevention → Process update → Review criteria → Next quarter
Example Integration:
Q1 Review Findings:
- "We found 5 ignored tests. Why?"
Q1 Retrospective:
- "Test X was failing intermittently. We skipped it to unblock releases."
Q1 Outcomes:
- Fix root cause of flaky test
- Add test to monitoring criteria
- Playbook update: "Always investigate skipped tests in Q1 review"
Q2 Review:
- Monitors for skipped tests automatically
- Finds 0 skipped tests (improvement!)
- Pattern: "Skipped tests went from 5 → 0"
Design Review Integration Points
Define where reviews fit in the workflow:
Option A: Continuous Review
Trigger: Every code push to main
Runs: During CI/CD
Output: GitHub check or PR comment
Effort: Medium (depends on scan speed)
Option B: Scheduled Review
Trigger: Weekly or quarterly
Runs: Off-hours or on-demand
Output: Report + GitHub issues for findings
Effort: Low (scheduled, low impact)
Option C: Session-Based Review
Trigger: After each major workflow (migration, release)
Runs: As part of workflow
Output: Integrated into workflow results
Effort: Varies (per-session analysis)
Option D: Manual Review
Trigger: User request ("@guru review")
Runs: On-demand
Output: Full report generated immediately
Effort: Medium (real-time analysis)
Review Checklist
When implementing review capability:
Review scope clearly defined (what issues to look for)
Review trigger designed (when does review run)
Review scripts created (F# implementation)
Review output format chosen (report/issues/notification)
Review findings documented (findings structure)
Integration with retrospectives designed
Integration with automation strategy designed
Integration with playbooks designed
Review schedule established (continuous/weekly/quarterly/on-demand)
Tested on real project data (not just examples)
Part 6: Cross-Agent Compatibility
Ensure Scripts Work Everywhere
Your F# scripts should work for Claude Code, Copilot, and all other agents:
Checklist:
Scripts use standard F# (no Claude-specific features)
## Using This Guru
**Claude Code:** Mention keywords like "release", "deploy", "publish"
**Copilot:** Read .agents/release-manager.md for equivalent guidance
**Other agents:** Run scripts directly: `dotnet fsi scripts/monitor-release.fsx`
Cross-Project Portability
Document how this guru could be used in other projects:
## Using This Guru in Other Projects
### Portable Components
- Decision trees (universal for this domain)
- Pattern catalog (concepts apply broadly)
- Script utilities (adapt paths for new project)
### Non-Portable Components
- Project-specific playbooks (morphir-dotnet release process)
- Integration with NUKE build system
- Version numbering conventions
### To Adapt to New Project
1. Update script paths (if paths differ)
2. Update build system integration (if not NUKE)
3. Adapt playbooks to new project's process
4. Customize templates for new project conventions
Estimated effort: 4-8 hours
Part 7: Workflow & Validation
Red-Green-Refactor for Skill Development
Follow TDD principles even for skills:
Red: Write test scenarios for the skill
Create BDD features showing how the guru should behave
Create decision tree tests (“Given this scenario, recommend this”)
Feature: Release Manager Guru
Scenario: Release fails and guru captures retrospective
Given a release is in progress
When the release fails
Then the guru should prompt for "What went wrong?"
And capture the response in the tracking issue
And suggest prevention strategies
Scenario: After 3 successful releases, guru prompts for improvements
Given 3 consecutive successful releases
When starting the 4th release
Then the guru should ask "What could we improve?"
Testing Checklist
Before releasing your guru:
Read through skill.md (is it clear? comprehensive?)
Test all automation scripts (do they work? return correct output?)
Validate decision trees (do they handle real scenarios?)
Check playbooks (are they complete? any steps missing?)
Review templates (are they usable? any clarifications needed?)
Test cross-agent compatibility (can Copilot users find equivalent info?)
Verify coordination (do other gurus know about this one?)
Get team feedback (does this feel useful? any blind spots?)
Part 8: Success Criteria
For Skill Delivery
Directory structure created
skill.md written (1000+ lines)
README.md created (300-400 lines)
MAINTENANCE.md documented
3-5 automation scripts implemented
5-10 seed patterns documented
3-5 templates created
Coordination points identified

Broken Links: Internal and external links that no longer work
Stale Examples: Code examples that don’t compile or produce wrong output
Missing Documentation: Public APIs without documentation
Style Violations: Documentation not following style guide
Outdated Content: Documentation that doesn’t match current behavior
Orphaned Content: Documentation that’s no longer referenced
Accessibility Issues: Content that isn’t accessible
Translation Issues: Content with culture-specific idioms
Review Frequency
Continuous: Link validation on documentation changes (CI/CD)
Per-PR: Example freshness check for PRs touching examples

## Summary
- Total documents scanned: N
- Issues found: N
- Critical: N | High: N | Medium: N | Low: N
## Broken Links (Critical)
| File | Line | Link | Status |
|------|------|------|--------|
| docs/readme.md | 42 | [link](./missing.md) | 404 Not Found |
## Stale Examples (High)
| File | Example | Issue |
|------|---------|-------|
| docs/tutorials/getting-started.md | Code block L15-25 | Compilation error |
## Missing Documentation (Medium)
| Type | Name | Location |
|------|------|----------|
| Public API | Morphir.Core.Validate | src/Morphir.Core/Validate.fs |
## Style Violations (Low)
| File | Issue | Suggestion |
|------|-------|------------|
| docs/api/readme.md | Heading style | Use sentence case |
## Recommendations
1. Fix broken links immediately
2. Update stale examples in next sprint
3. Add XML docs to new public APIs
4. Schedule style cleanup
Integration with Retrospectives
Review → Findings → Retrospectives → Process Improvement
Example Flow:
1. Q1 Review finds 15 broken links
2. Retrospective: "Links break when files move"
3. Process Update: Add link check to PR checklist
4. Q2 Review finds 3 broken links (improvement!)
5. Pattern: Link validation at PR time prevents breakage

Part 7: Pattern Catalog (Seed Patterns)
Pattern 1: API Documentation Structure
Context: Documenting a public API (class, method, interface)
Pattern:
/// <summary>/// Brief one-line description of what this does.
/// </summary>/// <remarks>/// Extended explanation if needed.
/// Use when you need to explain concepts, caveats, or usage patterns.
/// </remarks>/// <paramname="paramName">Description of parameter including valid values.</param>/// <returns>Description of return value, including null/empty cases.</returns>/// <exceptioncref="ArgumentException">When paramName is invalid because...</exception>/// <example>/// <code>/// var result = MyMethod("value");

### Pattern 3: CLI Command Documentation
**Context**: Documenting a CLI command
**Pattern**:
```markdown
# command-name
Brief description of what command does.
## Synopsis
command-name [options] [optional-arg]
## Description
Extended description explaining:
- Purpose and use cases
- How it relates to other commands
- Important concepts
## Arguments
| Argument | Description | Required |
|----------|-------------|----------|
| `<required-arg>` | Description | Yes |
| `[optional-arg]` | Description | No |
## Options
| Option | Shorthand | Description | Default |
|--------|-----------|-------------|---------|
| `--verbose` | `-v` | Enable verbose output | false |
## Examples
### Basic usage
```bash
command-name input.json
### Cause
Explanation of what causes this error.
### Solution
1. First thing to try
2. Second thing to try
3. If still failing, check...
### Example
```bash
# Command that causes error
$ morphir verify invalid.json
Error: INVALID_SCHEMA - Schema validation failed
# How to fix
$ morphir verify --schema v3 valid.json
---
### Pattern 5: Configuration Documentation
**Context**: Documenting configuration options
**Pattern**:
```markdown
# Configuration Reference
## Overview
Brief explanation of configuration system.
## Configuration File
Location: `morphir.config.json`or`package.json` under `morphir`key## Options
### `optionName`
-**Type**: `string | string[]`-**Default**: `"default value"`-**Required**: No
-**Since**: v1.2.0Description of what this option does andwhentouse it.
**Valid Values**:
-`"value1"`- Description
-`"value2"`- Description
**Example**:
```json
{"optionName": "value1"}
Notes:
Special consideration 1
Special consideration 2
---
### Pattern 6: Cross-Reference Best Practices
**Context**: Linking between documentation pages
**Pattern**:
- Use relative paths: `[Link text](./related.md)` not absolute URLs
- Link to specific sections: `[Section](./page.md#section-id)`
- Use descriptive link text: `[how to configure X](./config.md)` not `[click here](./config.md)`
- Add "See also" sections at end of documents
- Cross-link from conceptual to API to tutorial
**Anti-pattern**:
- `[here](./page.md)` - non-descriptive
- `https://github.com/.../docs/page.md` - will break on forks
- No cross-references - orphaned content
---
### Pattern 7: Mermaid Flowchart Best Practices
**Context**: Creating process or workflow diagrams
**Pattern**:
```mermaid
graph TD
subgraph "Input Phase"
A[Start] --> B{Validate Input}
end
subgraph "Processing Phase"
B -->|Valid| C[Process Data]
B -->|Invalid| D[Handle Error]
C --> E{Check Result}
end
subgraph "Output Phase"
E -->|Success| F[Return Result]
E -->|Failure| D
D --> G[Log Error]
G --> H[End]
F --> H
end
style A fill:#90EE90
style H fill:#FFB6C1
style D fill:#FFD700
Best Practices:
Use subgraphs to group related steps
Consistent node shapes: rectangles for actions, diamonds for decisions
Color code: green for start, red for end, yellow for errors
Label edges with conditions
Flow top-to-bottom or left-to-right
Keep diagrams focused - split if > 15 nodes
Anti-pattern:
No grouping - flat, hard-to-follow diagram
Inconsistent shapes - confuses readers
Missing edge labels on decisions
Overly complex - trying to show everything
Pattern 8: Mermaid Sequence Diagram Best Practices
Context: Showing interactions between components/actors
Pattern:
sequenceDiagram
autonumber
participant U as User
participant CLI as Morphir CLI
participant V as Validator
participant FS as File System
U->>CLI: morphir verify input.json
activate CLI
CLI->>FS: Read input file
FS-->>CLI: File contents
CLI->>V: Validate(content)
activate V
V->>V: Parse JSON
V->>V: Check schema
alt Valid
V-->>CLI: ValidationResult.Success
else Invalid
V-->>CLI: ValidationResult.Errors
end
deactivate V
CLI-->>U: Display result
deactivate CLI
Best Practices:
Use autonumber for step references
Name participants clearly with aliases
Show activation bars for processing time
Use alt/else for conditional flows
Use loop for repeated operations
Add notes for important clarifications
Keep interactions readable (< 20 messages)
Pattern 9: Hugo Frontmatter Best Practices
Context: Setting up Hugo page frontmatter
Pattern:
---

Draft pages in production
Pattern 10: Visual Storytelling
Context: Explaining complex concepts with visuals
Pattern: The “Zoom In” Technique
Start with the big picture
High-level architecture diagram
3-5 main components
No implementation details
Then zoom into details
Detailed view of each component
Show interfaces and interactions
Include relevant code snippets
Connect back to the whole
Reference the big picture
Explain how detail fits in
Link to related detailed views
Example Structure:
## Architecture Overview
Here's how the Morphir pipeline works at a high level:
[High-level flowchart - 5 boxes]
Let's dive into each stage...
### Stage 1: Input Processing
This stage handles [description]. Here's a closer look:
[Detailed sequence diagram for Stage 1]
This connects to Stage 2 via [interface description].
### Stage 2: Validation

1.6.1 - PRD: IR JSON Schema Verification
Product Requirements Document for Morphir IR JSON schema verification tooling
Product Requirements Document: IR JSON Schema Verification
Status: ✅ Phase 1 Complete | ⏳ Phase 2 Ready
Created: 2025-12-13
Last Updated: 2025-12-15
Phase 1 Completion Date: 2025-12-15
Current Phase: Phase 1 Complete - Ready for Phase 2
Author: Morphir .NET Team
Overview
This PRD defines the requirements for adding JSON schema verification capabilities to the Morphir .NET CLI and tooling. This feature will enable developers to validate Morphir IR JSON files against the official schema specifications for all supported format versions (v1, v2, v3).
The implementation will introduce WolverineFx as a messaging layer between the CLI and core tooling services, using Vertical Slice Architecture to organize features by use case rather than technical layers.
Problem Statement
Currently, developers working with Morphir IR JSON files have no built-in way to:
Validate IR correctness: Verify that generated or hand-written IR files conform to the expected schema
Debug format issues: Quickly identify structural problems in IR files
Ensure version compatibility: Confirm which schema version an IR file uses and whether it’s valid
Catch errors early: Detect malformed IR before it causes runtime failures in downstream tools
Current Pain Points
Manual validation: Developers must use external tools (Python jsonschema, Node.js ajv-cli) to validate IR
Version confusion: No automated way to detect which schema version an IR file uses
Poor error messages: External validators provide generic JSON schema errors without Morphir-specific context
Workflow friction: Validation requires switching between tools and languages
Goals
Primary Goals
Enable IR validation via CLI command for all supported schema versions (v1, v2, v3)
Establish WolverineFx integration with Vertical Slice Architecture as the foundation for future tooling commands
Provide excellent developer experience with clear, actionable error messages and multiple output formats
Support flexible input starting with file paths, with extensibility for stdin and multiple files
Auto-detect schema versions while allowing manual override when needed
Secondary Goals
Create reusable validation services in Morphir.Tooling that can be leveraged by other tools
Establish testing patterns using BDD scenarios for validation use cases
Document architectural decisions for Vertical Slice Architecture adoption
Non-Goals
Explicitly Out of Scope
IR migration/upgrade tooling: Will be addressed in a separate PRD (tracked below)
Schema generation: Creating schemas from .NET types
Real-time validation: IDE plugins or language servers
IR parsing/deserialization: This already exists in Morphir.Core
Schema authoring: Schemas are maintained in the upstream Morphir repository
User Stories
Story 1: Validate IR File
As a Morphir developer
I want to validate my IR JSON file against the official schema
So that I can catch structural errors before using the IR in other tools
Acceptance Criteria:
User runs morphir ir verify path/to/morphir-ir.json
Tool auto-detects schema version from JSON
Tool validates against appropriate schema
Tool returns clear success or detailed error messages
Exit code is 0 for valid, non-zero for invalid
Story 2: Validate Specific Schema Version
As a Morphir tooling developer
I want to validate IR against a specific schema version
So that I can test version-specific compatibility
Acceptance Criteria:
User runs morphir ir verify --schema-version 3 path/to/morphir-ir.json
Tool validates against specified schema version regardless of file content
Tool reports validation results for the specified version
Story 3: Machine-Readable Output
As a CI/CD pipeline
I want to get validation results in JSON format
So that I can parse and process errors programmatically
Acceptance Criteria:
User runs morphir ir verify --json path/to/morphir-ir.json
Tool outputs structured JSON with validation results
JSON includes error locations, messages, and metadata
Story 4: Quick Status Check
As a developer in a CI pipeline
I want to validate IR without verbose output
So that I can keep build logs clean
Acceptance Criteria:
User runs morphir ir verify --quiet path/to/morphir-ir.json
Tool only outputs errors (if any)
Exit code indicates success/failure
Story 5: Detect IR Version
As a Morphir developer
I want to identify which schema version my IR file uses
So that I know which tools and features are compatible
Acceptance Criteria:
User runs morphir ir detect-version path/to/morphir-ir.json
Tool analyzes IR structure and reports detected version
Tool provides confidence level or rationale for detection
Detailed Requirements
Functional Requirements
FR-1: Command Interface
Command Structure:
morphir ir verify <file-path> [options]
Required Arguments:
<file-path>: Path to the Morphir IR JSON file to validate
Options:
--schema-version <version>: Explicitly specify schema version (1, 2, or 3)
--json: Output results in JSON format
--quiet: Suppress output except errors
-v, --verbose: Show detailed validation information
Exit Codes:
0: Validation successful
1: Validation failed (schema errors)
2: Operational error (file not found, invalid JSON, etc.)
FR-2: Input Format Support
Phase 1 (Initial Release):
✅ File paths (absolute and relative)
Phase 2 (Future):
⏳ Stdin support: cat morphir-ir.json | morphir ir verify -
⏳ Multiple files: morphir ir verify file1.json file2.json file3.json
⏳ Directory validation: morphir ir verify --recursive ./ir-files/
FR-3: Schema Version Handling
Auto-Detection Logic (default behavior):
Look for formatVersion field in JSON
Analyze tag capitalization patterns:
All lowercase tags → v1
Mixed capitalization → v2
All capitalized tags → v3
If ambiguous, report detection failure with suggestions
Manual Override:
--schema-version option forces validation against specified version
Validate against JSON Schema Draft 07 specification
Provide detailed error locations using JSON Path notation
Include contextual information in error messages
FR-6: Version Detection Helper
Command:
morphir ir detect-version <file-path>
Output Example:
Detected schema version: v3
Confidence: High
Rationale:
- All tags are capitalized ("Library", "Public", "Apply", etc.)
- Contains formatVersion: 3
Implementation Status: ⏳ Planned for Phase 2
FR-7: Error Reporting Quality
Error Messages Must Include:
JSON Path to the error location
Expected value/format
Actual value found
Line and column numbers (when possible)
Suggested fixes (when applicable)
Example Error:
Error: Invalid access control tag
Location: $.modules[0].types["Account"].accessControlled[0]
Expected: One of ["Public", "Private"]
Found: "public"
Suggestion: Change "public" to "Public" (capitalize first letter)
Non-Functional Requirements
NFR-1: Performance
Targets:
Small files (<100KB): Validation completes in <100ms
Typical files (<1MB): Validation completes in <500ms
Large files (>1MB): Validation completes in <2 seconds
Benchmarking:
Use BenchmarkDotNet for performance testing
Test with representative IR files of varying sizes
Profile schema loading and validation separately
NFR-2: Reliability
Error Handling:
Gracefully handle malformed JSON with clear error messages
Catch and report file I/O errors (file not found, permission denied, etc.)
Handle edge cases: empty files, extremely large files, invalid UTF-8
Never crash; always return meaningful error messages
Validation Accuracy:
100% compliance with JSON Schema Draft 07 specification
Zero false positives (valid IR rejected)
Zero false negatives (invalid IR accepted)
NFR-3: Usability
CLI Experience:
Clear, consistent command naming following morphir <noun> <verb> pattern
Colored output for terminal readability (green=success, red=errors, yellow=warnings)
Progress indicators for large files
Helpful error messages with actionable suggestions
Documentation:
CLI help text: morphir ir verify --help

# Features/VerifyMultipleIR.featureScenario: Validate multiple files in batch
Given I have 10 valid IR files
When I run "morphir ir verify file1.json file2.json ... file10.json"
Then all 10 files should be validated
And the summary should show "10 valid, 0 invalid"
# Features/DetectVersion.featureScenario: Detect version with high confidence
Given a valid IR v3 file with formatVersion field
When I run "morphir ir detect-version file.json"
Then the detected version should be "3"
And the confidence level should be "High"
Integration Tests to Add:
CLI with stdin input (pipe)
CLI with multiple file arguments
CLI with glob patterns
Parallel processing performance

Product Requirements Document: Product Manager Skill for Morphir Ecosystem
Status: 📋 Draft
Created: 2025-12-18
Last Updated: 2025-12-18
Current Phase: Phase 1 - Planning and Design
Author: Morphir .NET Team
Related Issue: #228
Overview
This PRD defines requirements for creating a specialized Product Manager skill for AI coding agents. This skill will provide comprehensive product management capabilities tailored to the Morphir ecosystem across all FINOS Morphir repositories, helping users create better PRDs, craft meaningful issues, understand the ecosystem, and make product decisions aligned with Morphir’s philosophy.
Problem Statement
Currently, contributors working across the Morphir ecosystem face several challenges:
Fragmented Knowledge: Morphir spans multiple repositories (morphir-elm, morphir-jvm, morphir-scala, morphir-dotnet, etc.) with varying maturity levels, features, and conventions
Inconsistent Issue Quality: Issues and PRs often lack context, proper categorization, or alignment with project goals
PRD Gaps: Not all features have comprehensive PRDs, and creating high-quality PRDs requires deep Morphir knowledge
Cross-Repo Blind Spots: Contributors may duplicate work or miss opportunities for cross-repository synergies
UX/DX Debt: User experience and developer experience improvements need dedicated advocacy
Manual Ecosystem Tracking: No automated way to track trends, backlogs, or health metrics across the ecosystem
Current Pain Points
New contributors struggle to understand where to contribute and how to write good issues
Maintainers spend time triaging poorly-written issues and PRs
Product decisions lack ecosystem-wide context and may not align with Morphir’s functional modeling philosophy
Documentation gaps make it hard to understand feature status across implementations
Backlog management is manual and repository-siloed
Goals
Primary Goals
Expert PRD Guidance: Help users create comprehensive, well-structured PRDs aligned with Morphir principles
Issue Quality Improvement: Assist in crafting high-quality issues (bugs, features, enhancements) with proper context
Ecosystem Intelligence: Provide real-time awareness of backlogs, trends, and status across all Morphir repositories
UX/DX Advocacy: Champion user and developer experience improvements

Cross-Repository Queries:
// Example: Find all IR-related issues across ecosystem
let irIssues = MorphirRepos.All
|> Seq.collect (fun repo -> GitHub.queryIssues repo "label:IR")|> Seq.sortByDescending (_.UpdatedAt)
queryEcosystemIssues {

Knowledgebase Management
Purpose: The Product Manager skill maintains a curated knowledgebase of Morphir ecosystem knowledge as markdown files within the skill directory. This enables offline access, version control, and structured knowledge organization.
// update-knowledge.fsx: Fetch latest info from live sources
// Usage: dotnet fsi update-knowledge.fsx --category repositories
// Fetch latest README from each repo
let updateRepositoryDocs repos = repos
|> Seq.iter (fun repo ->let readme = GitHub.fetchFile repo "README.md"let repoDoc = Knowledge.parseRepositoryInfo readme
Knowledge.save $"knowledge/repositories/{repo.name}.md" repoDoc
)// Fetch latest feature status
let updateFeatureMatrix () =let cliFeatures = MorphirRepos.All
|> Seq.collect (fun repo -> GitHub.searchCode repo "CLI commands") Knowledge.generateFeatureMatrix cliFeatures
|> Knowledge.save "knowledge/features/cli-tools.md"// Validate knowledgebase consistency
let validateKnowledge () = Knowledge.checkBrokenLinks ()
Knowledge.validateMarkdown ()
Knowledge.checkOutdatedInfo ()
Knowledge Access Patterns:
When asked about Morphir principles:
1. Read knowledge/morphir-principles.md
2. Cite specific sections with links
3. Provide examples from knowledge/faq/
When comparing repos:
1. Read knowledge/ecosystem-map.md for overview
2. Read specific knowledge/repositories/{repo}.md
3. Consult knowledge/features/ for capability matrix
When validating feature alignment:
1. Reference knowledge/morphir-principles.md
2. Check knowledge/architecture/ for design patterns
3. Review knowledge/faq/product-decisions.md for precedents
Knowledge Maintenance:
Manual Curation: Maintainers update knowledge files as authoritative sources
Periodic Updates: Run update-knowledge.fsx quarterly to refresh from live sources
Version Control: Knowledge evolves with the skill, tracked in git
Validation: CI validates markdown formatting and internal links
Review Process: Knowledge changes reviewed like code changes
Knowledge vs. Live Data:
Knowledgebase: Stable, curated, architectural, and philosophical knowledge
Live Queries: Real-time issue data, PR status, recent activity
Hybrid Approach: Use knowledge for context, live queries for current state
PRD Template Engine
Interactive Generation:
// Prompt user for each section
let prd = PRD.Interactive [ Section.Overview [ Question "What feature are you proposing?" Question "Why is this feature needed?"] Section.Goals [ Question "What are the primary goals? (one per line)" Question "What is explicitly out of scope?"]// ... more sections
]// Validate completeness
let validation = PRD.validate prd
// Save to file
PRD.save "docs/content/contributing/design/prds/my-feature.md" prd
Skill Activation Triggers
Keywords:
“PRD”, “product requirements”, “feature spec”

Scenarios:
User asks for help creating a PRD
User wants to file an issue
User asks “what should I work on?”
User asks about feature status across repos
User proposes a feature that may not align
User asks about Morphir architecture or principles
Q3: Should F# scripts use GitHub CLI or direct API calls?
Status: Open
Options:
GitHub CLI (gh) for simplicity and auth
Direct API calls via HTTP client for flexibility
Hybrid approach
Recommendation: GitHub CLI for Phase 1, evaluate direct API if needed
Decision Needed By: Phase 1 (Week 1)
Impact: Affects script architecture and dependencies
Q4: How deep should trend analysis go?
Status: Open
Options:
Label frequency and time-series only
Add NLP for theme extraction from titles/descriptions
Add sentiment analysis
Recommendation: Start with label frequency, add NLP in Phase 3 if valuable
Decision Needed By: Phase 3 (Week 3)
Impact: Affects trend-analysis.fsx complexity and dependencies
Refactor the morphir-dotnet deployment architecture to fix critical packaging issues, separate tool distribution from executable distribution, implement comprehensive build testing, and establish changelog-driven versioning as the single source of truth.
Problem: The current deployment failed due to package naming mismatches (lowercase “morphir” vs “Morphir”), inconsistent tool command naming, and lack of automated testing to catch these issues before CI deployment.
Solution: Separate concerns into distinct projects (Morphir.Tool for dotnet tool, Morphir for executables), reorganize build system following vertical slice architecture, implement Ionide.KeepAChangelog for version management, and add comprehensive build testing infrastructure.
Impact: Eliminates deployment failures, provides clear distribution strategy for different user personas, enables confident releases with automated validation, and establishes maintainable build architecture.
Successful deployment to NuGet.org and GitHub Releases
✅ Separate concerns
Distinct Morphir.Tool project for dotnet tool
Morphir project for standalone executables
Clear boundaries and responsibilities
✅ Implement comprehensive testing
Package structure validation
Metadata correctness verification
Local installation smoke tests
Catch issues before CI deployment
✅ Establish changelog-driven versioning
CHANGELOG.md as single source of truth
Ionide.KeepAChangelog integration
Support pre-release versions (alpha, beta, rc)
Automated release preparation
✅ Dual distribution strategy
NuGet tool package for .NET developers
GitHub releases with executables for non-SDK users
Persona-based documentation
✅ Organize build system
Split Build.cs by domain (vertical slices)
Extract helper classes for testability
Align with Morphir.Tooling architecture
Maintainable and scalable structure
Non-Goals
❌ Automated pre-release version bumping (Phase 2, future work)
❌ TestContainers integration (Phase 3 of testing, when needed)
❌ Package rename/migration (Keeping current names for backward compatibility)
❌ Breaking changes to public APIs (Maintain compatibility)
var toolPackage = OutputDir.GlobFiles("Morphir.Tool.*.nupkg")
.FirstOrDefault();
BDD Tests:
Feature: Project structure refactor
Scenario: Build Morphir.Tool package
Given Morphir.Tool project exists
When I run "./build.sh PackTool"
Then Morphir.Tool.*.nupkg should be created
And package should contain tools/net10.0/any/morphir.dll
Scenario: Build split successfully
Given Build.cs is split into partial classes
When I run "./build.sh --help"
Then all targets should be available
And no build errors should occur
cd build
dotnet add package Ionide.KeepAChangelog --version 0.2.0
Add using statement to Build.cs:
using KeepAChangelogParser;
using Semver;
2.2 Implement Version Extraction
Create ChangelogHelper.GetVersionFromChangelog():
publicstatic SemVersion GetVersionFromChangelog(AbsolutePath changelogPath)
{
var content = File.ReadAllText(changelogPath);
var parser = new ChangelogParser();
var result = parser.Parse(content);
if (!result.IsSuccess)
thrownew Exception($"Failed to parse CHANGELOG.md: {result.Error}");
var changelog = result.Value;
var latest = changelog.SectionCollection.FirstOrDefault()
?? thrownew Exception("No releases found in CHANGELOG.md");
if (!SemVersion.TryParse(latest.MarkdownVersion, SemVersionStyles.Any, outvar version))
thrownew Exception($"Invalid version: {latest.MarkdownVersion}");
return version;
}
2.3 Implement Release Notes Extraction
Create ChangelogHelper.GetReleaseNotes():
publicstaticstring GetReleaseNotes(AbsolutePath changelogPath)
{
var content = File.ReadAllText(changelogPath);
var parser = new ChangelogParser();
var result = parser.Parse(content);
if (!result.IsSuccess) returnstring.Empty;
var latest = result.Value.SectionCollection.FirstOrDefault();
if (latest == null) returnstring.Empty;
var notes = new StringBuilder();
AppendSection("Added", latest.SubSections.Added);
AppendSection("Changed", latest.SubSections.Changed);
// ... other sectionsreturn notes.ToString();
}
publicstatic SemVersion GetNextPreReleaseVersion(AbsolutePath changelogPath)
{
var currentVersion = GetVersionFromChangelog(changelogPath);
if (!currentVersion.IsPrerelease)
thrownew Exception("Cannot auto-bump non-prerelease version");
// Extract pre-release type and number// e.g., "alpha.1" → type: "alpha", number: 1var prereleaseParts = currentVersion.Prerelease.Split('.');
var type = prereleaseParts[0]; // alpha, beta, preview, rcvar number = int.Parse(prereleaseParts.Length > 1 ? prereleaseParts[1] : "0");
// Increment number number++;
// Create new versionvar newPrerelease = $"{type}.{number}";
returnnew SemVersion(
currentVersion.Major,
currentVersion.Minor,
currentVersion.Patch,
newPrerelease
);
}
Create target for auto-bump (used in CI):
Target BumpPreRelease => _ => _
.Description("Auto-bump pre-release version (CI only)")
.Executes(() =>
{
var currentVersion = Version;
if (!currentVersion.IsPrerelease)
{
Serilog.Log.Information("Not a pre-release, skipping auto-bump");
return;
}
var nextVersion = ChangelogHelper.GetNextPreReleaseVersion(ChangelogFile);
Serilog.Log.Information("Auto-bumping {0} → {1}", currentVersion, nextVersion);
// Update CHANGELOG.md with empty section for next pre-release ChangelogHelper.AddPreReleaseSection(ChangelogFile, nextVersion.ToString());
});
BDD Tests:
Feature: Changelog-driven versioning
Scenario: Extract version from CHANGELOG
Given CHANGELOG.md has [0.2.1] - 2025-12-20When I call GetVersionFromChangelog()
Then version should be 0.2.1Scenario: Prepare release
Given CHANGELOG.md has [Unreleased] with content
When I run "./build.sh PrepareRelease --version 0.2.1"
Then CHANGELOG.md should have [0.2.1] - 2025-12-20And [Unreleased] should be empty
And changes should be staged
Scenario: Block release without content
Given CHANGELOG.md [Unreleased] is empty
When I run "./build.sh PrepareRelease --version 0.2.1"
Then build should fail
And error should mention "empty"
Feature: Build testing infrastructure
Scenario: Validate tool package structure
Given Morphir.Tool package is built
When I run package structure tests
Then all required files should be present
And tool settings should be correct
Scenario: Validate version consistency
Given all packages are built
When I run metadata tests
Then all packages should have same version
And version should match CHANGELOG.md
Scenario: Test local installation
Given tool package is in local folder
When I install tool from local source
Then installation should succeed
And morphir command should be available

Scenario: Block deployment if version not in CHANGELOG
Given tag v0.2.2 is pushed
But CHANGELOG.md doesn't have [0.2.2]
When deployment workflow runs
Then workflow should fail
And no packages should be published
Phase 5: Documentation (1-2 days)
Goal: Comprehensive documentation for all stakeholders
Tasks
5.1 Update AGENTS.md
Add section: “Build System Configuration”
## Build System Configuration
### Nuke Parameters
The build system uses Nuke with these parameters:
-`--configuration`: Build configuration (Debug/Release)
-`--version`: Version override (reads from CHANGELOG.md by default)
-`--api-key`: NuGet API key for publishing
-`--nuget-source`: NuGet source URL
-`--skip-tests`: Skip test execution
### Environment Variables
-`NUGET_TOKEN`: NuGet API key (CI only)
-`CONFIGURATION`: Build configuration override
-`MORPHIR_EXECUTABLE_PATH`: E2E test executable path
Add section: “Changelog-Driven Versioning”
## Changelog-Driven Versioning
Morphir uses CHANGELOG.md as the single source of truth for versions.
### Version Format
Follows [Semantic Versioning](https://semver.org/):
-`MAJOR.MINOR.PATCH` for releases (e.g., `0.2.1`)
-`MAJOR.MINOR.PATCH-TYPE.NUMBER` for pre-releases (e.g., `0.2.1-beta.2`)
Supported pre-release types: alpha, beta, preview, rc
### Release Preparation Workflow
1. During development, add changes to `[Unreleased]` section
2. When ready to release, run: `./build.sh PrepareRelease --version X.Y.Z`3. Review staged changes: `git diff --staged`4. Commit: `git commit -m "chore: prepare release X.Y.Z"`5. Create release branch: `git checkout -b release/X.Y.Z`6. Push and create PR to main
7. After PR merge, create tag: `git tag -a vX.Y.Z -m "Release X.Y.Z"`8. Push tag: `git push origin vX.Y.Z` (triggers deployment)
Add section: “Dual Distribution Strategy”
## Dual Distribution Strategy
Morphir provides two distribution channels:
### NuGet Tool Package (Morphir.Tool)
**For**: .NET developers with SDK installed
**Install**: `dotnet tool install -g Morphir.Tool`**Update**: `dotnet tool update -g Morphir.Tool`**Command**: `morphir`### Platform Executables
**For**: Shell scripts, containers, non-.NET environments
**Install**: Use install scripts or download from GitHub releases
**Platforms**: linux-x64, linux-arm64, win-x64, osx-arm64
**Command**: `morphir` or `./morphir-{platform}`
5.2 Update CLAUDE.md
Add build organization guidance
Document PrepareRelease workflow
Add testing requirements
Update commit message examples
5.3 Update README.md
Add persona-based installation instructions:
## Installation
### For .NET Developers
If you have the .NET SDK installed:
```bash
dotnet tool install -g Morphir.Tool
morphir --version
For Shell Scripts / Containers
If you don’t have .NET SDK or need a standalone executable:
Feature: Morphir Tool Installation
As a .NET developer
I want to install Morphir as a dotnet tool
So that I can use it in my development workflow
Scenario: Install from NuGet
Given I am a .NET developer with SDK installed
When I run "dotnet tool install -g Morphir.Tool"
Then the tool should install successfully
And I should be able to run "morphir --version"
And the version should match CHANGELOG.md
Scenario: Update tool
Given Morphir.Tool is already installed
When I run "dotnet tool update -g Morphir.Tool"
Then the tool should update successfully
And the new version should be active
Feature: Morphir Executable Download
As a shell script user
I want to download a standalone executable
So that I can use Morphir without installing .NET SDK
Scenario: Download from GitHub releases
Given I am using a minimal container
When I download morphir-linux-x64 from GitHub releases
Then I should be able to run "./morphir-linux-x64 --version"
And the version should match CHANGELOG.md
Scenario: Install via script
Given I have curl available
When I run the install script
Then morphir should be installed to /usr/local/bin
And morphir command should be in PATH
BDD Tests:
Feature: Documentation completeness
Scenario: All distribution methods documented
Given README.md exists
When I read installation instructions
Then I should see dotnet tool installation
And I should see executable download instructions
And I should see persona-based recommendations
Scenario: Release process documented
Given AGENTS.md exists
When I read the release preparation section
Then I should see PrepareRelease workflow
And I should see tag creation steps
And I should see deployment trigger explanation
BDD Acceptance Criteria
Epic-Level Scenarios
Feature: Morphir Deployment Architecture
As a Morphir maintainer
I want a robust deployment architecture
So that releases are reliable and users can install easily
Background: Given the morphir-dotnet repository is up to date
And all dependencies are installed
Scenario: Successful deployment to NuGet and GitHub
Given CHANGELOG.md has [0.2.1] - 2025-12-20And all changes are committed
When I create and push tag v0.2.1Then deployment workflow should complete successfully
And Morphir.Tool.0.2.1.nupkg should be published to NuGet.org
And Morphir.Core.0.2.1.nupkg should be published to NuGet.org
And Morphir.Tooling.0.2.1.nupkg should be published to NuGet.org
And morphir-linux-x64 should be in GitHub release v0.2.1And morphir-win-x64 should be in GitHub release v0.2.1And morphir-osx-arm64 should be in GitHub release v0.2.1And release notes should match CHANGELOG.md
Scenario: Build tests catch package issues
Given I modify package structure incorrectly
When I run "./build.sh TestBuild"
Then tests should fail
And I should see clear error message
And CI deployment should be blocked
Scenario: Version consistency across packages
Given I prepare release 0.2.1When I build all packages
Then all packages should have version 0.2.1And version should match CHANGELOG.md [0.2.1]
And all package release notes should match
Scenario: .NET developer installation
Given Morphir.Tool is published to NuGet
When .NET developer runs "dotnet tool install -g Morphir.Tool"
Then tool should install successfully
And "morphir --version" should work
And version should match published version
Scenario: Container user installation
Given morphir-linux-x64 is in GitHub releases
When container user downloads executable
Then "./morphir-linux-x64 --version" should work
And version should match release version
And no .NET SDK should be required
Product Requirements Document for layered Morphir configuration and workspace support
Product Requirements Document: Layered Configuration and Workspaces
Status: 📋 Draft Created: 2025-12-22 Last Updated: 2025-12-22 Author: Morphir .NET Team
Overview
Introduce a layered configuration system for Morphir tooling with global and workspace-scoped TOML files, optional user and CI overlays, and standardized cache path resolution. Centralize configuration models in a new F# project (Morphir.Configuration) so all tools can share the same domain types. Morphir.Tooling will reference Morphir.Configuration and provide resolver and IO services.
Problem Statement
Morphir tooling lacks a consistent configuration mechanism for workspace-scoped settings, user-specific overrides, and CI-specific behavior. This results in scattered, ad-hoc configuration approaches, inconsistent cache locations, and poor ergonomics for CLI usage in CI/CD environments.
Goals
Provide layered configuration with deterministic precedence across global, workspace, user, and CI overlays.
Define workspace discovery rules and standard config file locations.
Centralize configuration domain models in Morphir.Configuration (F#).
Expose a resolver in Morphir.Tooling with a clear API for consumers.
Document configuration files, precedence, and CI activation behavior.
Non-Goals
Implementing cache read/write behavior (only path resolution and configuration).
Introducing new CLI commands beyond config selection and CI activation flags.
Complex schema validation beyond basic TOML parsing and sanity checks.
Breaking compatibility with existing tooling workflows without migration guidance.
User Stories
Story 1: Workspace Configuration
As a developer I want workspace-level Morphir configuration in .morphir/morphir.toml So that I can keep project settings out of the repository root
Story 2: Personal Overrides
As a developer I want a local override file (.morphir/morphir.user.toml) So that I can keep personal settings out of version control
Story 3: CI Profiles
As a CI pipeline I want a CI overlay (.morphir/morphir.ci.toml) So that CI-specific settings apply only when needed
Story 4: Global Defaults
As a developer I want global defaults in OS-standard config locations So that I can reuse defaults across repositories
Detailed Requirements
Functional Requirements
FR-1: Layered Precedence
Load configuration in the following order (lowest to highest precedence):
Global config (OS-standard path)
Workspace config: .morphir/morphir.toml
User override: .morphir/morphir.user.toml (optional)
CI override: .morphir/morphir.ci.toml (optional, conditional)
FR-2: Workspace Root Discovery
Workspace root is discovered by:
VCS root (Git) when available.
If no VCS root is found, the nearest .morphir/ directory when walking up from the current directory.
If neither is found, treat as no workspace configuration.
Log selection decisions and conflicts (e.g., when .morphir/ exists below VCS root).
Linux: $XDG_CONFIG_HOME/morphir or ~/.config/morphir
macOS: ~/Library/Application Support/morphir
Global config file name: morphir.toml.
FR-5: Cache Paths (Resolution Only)
Expose resolved cache paths:
Workspace cache: .morphir/cache/ (overridable by config)
Global cache: OS-standard cache dir (overridable by config)
No caching behavior is implemented in this phase.
FR-6: Shared Domain Models
Create a new F# project:
src/Morphir.Configuration/ containing domain models and pure configuration types
tests/Morphir.Configuration.Tests/ containing unit tests for models and parsing behavior
Morphir.Tooling references Morphir.Configuration and provides the resolver and IO boundary.
Non-Functional Requirements
Deterministic merging behavior with explicit precedence.
Minimal dependencies; avoid heavy configuration frameworks.
Respect CLI logging rules (stdout reserved for command output; diagnostics to stderr).
Keep domain models immutable and free of IO.
Proposed Architecture
Projects
Morphir.Configuration (F#)
Config models (records, DU types)
Pure merge logic
CI activation options and detection helpers (pure, env injected)
Morphir.Tooling (C# / F#)
Config loader/resolver

Optional fields and missing values
CI activation mode handling (with injected env map)
Morphir.Tooling.Tests
Global path selection per OS (parameterized)
Workspace discovery rules
Layered load behavior with missing optional files
CI activation flag (on/off/auto) and detection
Documentation Requirements
New documentation page describing config locations, precedence, and CI behavior.
Update troubleshooting doc with config resolution guidance.
Add .morphir/morphir.user.toml and cache paths to git-ignore guidance.
Minimal TOML Schema (v1)
morphir.toml supports optional project, workspace, and morphir sections.
morphir is optional and contains dist, tools, and extensions subsections (defaults apply when omitted).
workspace.projects accepts an array of project globs for monorepo layouts.
workspace.outputDir defaults to ${WorkspaceHome}/out/.
WorkspaceHome defaults to the .morphir/ folder at the workspace root and is overridable via config.
project defaults to supporting the properties currently available in the Morphir project file (morphir.json in finos/morphir-elm).

Add an optional morphir section containing dist, tools, and extensions subsections (defaults apply when omitted).
workspace.projects accepts an array of project globs for monorepo layouts.
workspace.outputDir defaults to ${WorkspaceHome}/out/.
WorkspaceHome defaults to the .morphir/ folder at the workspace root and is overridable via config.
project defaults to supporting the properties currently available in the Morphir project file (morphir.json in finos/morphir-elm).
1.6.6 - Vulnerability Resolver Skill Requirements
Product requirements for the Vulnerability Resolver skill - automated CVE detection, resolution, and suppression
Vulnerability Resolver Skill Requirements
Executive Summary
The Vulnerability Resolver skill provides automated assistance for managing security vulnerabilities detected by OWASP Dependency-Check. It enables developers to efficiently triage, fix, or suppress CVEs while maintaining a documented audit trail of security decisions.
Background
Context
FINOS active projects require CVE scanning alongside Dependabot. morphir-dotnet implemented OWASP Dependency-Check scanning in PR #273, which runs:
On push/PR to main
Weekly on Monday at 3:00 UTC
Fails builds on CVSS score >= 7
PR #276 addressed initial vulnerabilities, identifying that some reported CVEs were false positives due to binary scanning misidentification of package versions or confusion with similarly-named packages.
Problem Statement
When dependency scanning detects vulnerabilities:
Developers must manually research each CVE to determine if it’s genuine or a false positive
There’s no standardized process for documenting suppression decisions
Suppression files must be manually created following OWASP Dependency-Check XML schema
No easy way to trigger scans on specific branches during development
No guided workflow for fix vs. suppress decisions
Success Criteria
Automation: Reduce manual effort for vulnerability resolution by 70%
Documentation: 100% of suppressions have documented rationale
Auditability: Clear audit trail for all security decisions
Developer Experience: Interactive prompts guide users through resolution
CI Integration: Ability to trigger scans on any branch
Functional Requirements
FR-1: Scan Triggering
FR-1.1: Trigger dependency-check workflow on any branch
# Example invocation@skill vulnerability-resolver
Scan branch feature/new-dependency for vulnerabilities
FR-1.2: Support manual workflow dispatch with parameters:
Branch/ref to scan
Fail threshold (CVSS score, default 7)
Output format (HTML, JSON, XML)
Suppression file path
FR-1.3: Report scan status and provide link to workflow run
FR-2: Vulnerability Analysis
FR-2.1: Parse dependency-check reports (HTML, JSON, XML formats)
FR-2.2: For each vulnerability, extract:
CVE identifier
CVSS score and severity
Affected package/file
Package identifier (purl, CPE)
Description and references
Whether it’s a transitive dependency
FR-2.3: Categorize vulnerabilities by:
Severity (Critical, High, Medium, Low)
Fix availability (update available, no fix, N/A)
False positive likelihood (based on patterns)
FR-3: Interactive Resolution
FR-3.1: Present vulnerabilities with resolution options:
CVE-2022-4742 (CVSS 9.8) in JsonPointer.Net@6.0.0
Options:
1. Fix: Update to version 6.0.1 (recommended)
2. Suppress: Mark as false positive with reason
3. Skip: Handle later
4. Research: Open CVE details in browser
FR-3.2: For each resolution choice:
Fix: Generate package update commands, verify fix in scan
Suppress: Create/update suppression XML with documented rationale
Skip: Track for follow-up, don’t block
FR-3.3: Detect false positive patterns:
Version misidentification in binary scanning
Package name confusion (e.g., Cecil vs Mono.Cecil)
Already-fixed transitive dependencies
Suggest suppression when patterns match
FR-4: Suppression Management
FR-4.1: Create and manage suppression file (dependency-check-suppressions.xml)
FR-4.2: Suppression file structure following OWASP schema:
FR-5.1: Generate fix commands for different package managers:
# NuGet (Directory.Packages.props)# Update JsonPointer.Net from 6.0.0 to 6.0.1# In Directory.Packages.props:<PackageVersion Include="JsonPointer.Net" Version="6.0.1" />
FR-5.2: Verify fix effectiveness:
Check if new version resolves CVE
Warn if update introduces breaking changes
Validate update doesn’t introduce new CVEs
FR-5.3: Handle transitive dependencies:
Identify which direct dependency pulls the vulnerable package
Suggest upgrade path
Note when fix requires waiting for upstream update
FR-6: Reporting and Documentation
FR-6.1: Generate resolution summary:

Issue #240: Create Elm to F# Guru Skill - Enhanced Edition
Enhancement of: Issue #240 Enhancement based on: Issue #253 - Unified Cross-Agent AI Skill Framework Architecture Related Issues: #254, #255, #241, #242
Summary
Create a specialized Elm-to-F# Guru skill that facilitates high-quality migration of Elm code to idiomatic F#, with proactive review capability built-in from day one. This guru combines domain expertise, automation, continuous improvement, and cross-project portability principles from the unified skill framework.
The Elm-to-F# Guru will be the first guru built with review capability from the start, establishing a pattern for future gurus and demonstrating the full power of the guru framework.
1. Proactive Review Capability ⭐ NEW
The Elm-to-F# Guru includes proactive review as a core competency, not an afterthought. This sets it apart from earlier gurus where review capabilities were added later.
What the Guru Reviews
The Elm-to-F# Guru actively monitors migration progress and quality, identifying:
1.1 Anti-Patterns
Elm idioms ported literally instead of idiomatically
Example: Elm’s Maybe translated directly to Option without considering F#’s ValueOption or nullable reference types where appropriate
Example: Elm’s union types with overly verbose F# discriminated unions when simpler patterns exist
1.2 Myriad Plugin Opportunities
Patterns appearing 3+ times that should be automated via code generation
Example: Repetitive JSON serialization patterns across multiple types
Example: Boilerplate for F# record validation that mirrors Elm’s structure
Example: Type conversions between Elm and F# representations
1.3 F# Idiom Violations
Code using non-idiomatic F# patterns
Example: Excessive use of mutable variables when immutable patterns are clearer
Example: Missing type annotations in public APIs
Example: Not using F# computation expressions where appropriate
Example: Type provider output is AOT-compatible (coordination with AOT Guru)
Review Triggers
The guru performs reviews at multiple cadences:
Session-Based Review (After Each Module Migration)
Trigger: Module migration marked complete
Action: Analyze migration for:
- Pattern frequency (track repetitions)
- Idiom compliance (F# best practices)
- Type safety preservation (Elm → F#)
- Test coverage (coordinate with QA Tester)
Output: Session summary with patterns discovered
Weekly Pattern Inventory Review
Trigger: Weekly scheduled scan (CI job or manual)
Action: Review all migrations from past week:
- Aggregate pattern occurrences
- Identify patterns appearing 3+ times
- Check for emerging anti-patterns
Output: Weekly pattern report
Quarterly Comprehensive Review
Trigger: End of quarter (Q1, Q2, Q3, Q4)
Action: Deep analysis across all migrations:
- Pattern frequency trends (increasing/decreasing)
- Myriad plugin opportunities (automation candidates)
- Migration quality metrics (idiom compliance, safety)
- Coordination effectiveness (AOT Guru, QA Tester)
Output: Quarterly review report with improvement recommendations
Review Output Format
Reviews produce structured output for consumption by other gurus and developers:
## Elm-to-F# Migration Review Report
**Date:** 2025-12-19
**Scope:** Modules migrated since last review
**Reviewer:** Elm-to-F# Guru
### Pattern Frequency Report
| Pattern | Count | Example Locations | Status |
|---------|-------|-------------------|--------|
| ValueType boxing in pattern matching | 7 | `Module.A:45`, `Module.B:23`, ... | ⚠️ Recommend Myriad plugin |
| Manual JSON serialization | 5 | `Module.C:12`, `Module.D:67`, ... | ⚠️ Consider automation |
| Recursive union type translation | 12 | `Module.E:89`, `Module.F:34`, ... | ✅ Pattern documented |
### Myriad Plugin Recommendations
1.**Auto-Serializer Plugin** (Priority: High)
- **Pattern:** Manual JSON serialization appears 5+ times
- **Impact:** Reduce boilerplate, improve consistency
- **Effort:** ~2-3 days to implement
- **Token Savings:** ~50 tokens per type × 20 types = ~1000 tokens
2.**ValueType Boxing Detector** (Priority: Medium)
- **Pattern:** Boxing detected 7 times
- **Impact:** Performance + AOT compatibility
- **Effort:** ~1 day to implement detection script
- **Token Savings:** ~30 tokens per detection × 10/quarter = ~300 tokens
### Automation Script Suggestions
1.**Create `detect-boxing-patterns.fsx`**- Scans F# code for ValueType boxing in pattern matches
- Integrates with AOT Guru's IL analysis
2.**Create `validate-type-mappings.fsx`**- Verifies Elm → F# type mappings are correct
- Checks for precision loss (e.g., Elm Int → F# int vs int64)
### Migration Quality Metrics
- **Modules Migrated:** 80
- **Idiom Violations:** 1,200 (decreasing from 1,500 last quarter)
- **Patterns Discovered:** 45 total (12 new this quarter)
- **Test Coverage:** 82% (target: 80%, ✅ on target)
- **AOT Compatibility:** 95% (5% needs Myriad plugins)
### Coordination Status
- **With AOT Guru:** 3 generated code reviews completed, 2 IL warnings resolved
- **With QA Tester:** Test coverage verified, 5 edge cases added
- **With Release Manager:** Migration progress tracked, on schedule for Q1 2026
### Next Quarter Focus
1. Implement auto-serializer Myriad plugin
2. Add boxing detection to quarterly scans
3. Document recursive union type pattern (12 occurrences suggest it's stable)
4. Coordinate with AOT Guru on plugin IL output
2. Automated Feedback & Continuous Improvement
The Elm-to-F# Guru implements a continuous learning loop inspired by the guru framework’s retrospective philosophy.
Session Capture
Every migration session includes a “Patterns Discovered” section:
## Migration Session: Module.BusinessLogic
**Status:** Complete
**Lines Migrated:** 450
**F# Output:** 380 lines
### Patterns Discovered
1.**Union Type with Private State**: Elm's opaque types → F# with private constructor pattern
2.**Computation Expression Candidate**: Repeated `Result` chaining → F# `result { }` CE
3.**Myriad Opportunity**: 3rd occurrence of manual JSON serialization for discriminated unions
### Idiom Improvements
- Changed: Mutable loop → `List.fold` (idiomatic F#)
- Fixed: Added explicit type annotations to public API
- Enhanced: Used `ValueOption` instead of `Option` for high-frequency code paths
### Questions for Next Review
- Should we create a Myriad plugin for opaque type translation?
- Is the `Result` computation expression approach consistent with project standards?
Quarterly Reviews
At the end of each quarter, the guru performs a comprehensive pattern review:
Process:
Collect: Gather all “Patterns Discovered” sections from the quarter
Analyze: Identify top 3-5 patterns by frequency
Decide: Determine which patterns warrant automation (Myriad plugin, script, or decision tree update)
Document: Update the guru’s pattern catalog and playbooks
Plan: Set improvement goals for next quarter
Example Quarterly Review Outcomes:
Q1 2025 Review:
- Discovered 15 new patterns (total: 45)
- Top pattern: JSON serialization (appeared 18 times)
- Decision: Create Myriad plugin for auto-serialization
- Playbook updated: Added decision tree for union type translation
Q2 2025 Review:
- Created 2 Myriad plugins (auto-serialization, validation)
- JSON serialization occurrences dropped from 18 → 2 (automation working!)
- New pattern emerged: Recursive tree structures (8 occurrences)
- Decision: Document pattern, not yet frequent enough for plugin
Q3 2025 Review:
- Updated migration decision tree based on Q1-Q2 learnings
- Pattern catalog now has 52 patterns (7 added, no removals)
- Token savings from automation: ~2,500 tokens per quarter
- Coordination with AOT Guru improved (generated code review process)
Playbook Evolution
The guru’s playbooks and decision trees evolve based on learnings:
Before: Generic “Translate Elm to F#” steps
After Q1: Specific guidance on union types, computation expressions, serialization
After Q2: Automation scripts integrated, Myriad plugin usage documented
After Q3: Common pitfalls section added, anti-pattern detection automated
Automation Loop
The feedback loop prioritizes automation:
Pattern appears 1-2 times → Document in catalog
Pattern appears 3-5 times → Create detection script + decision tree entry
Pattern appears 6+ times → Strong candidate for Myriad plugin or major automation
Pattern appears 10+ times → Critical to automate (prevent technical debt)
3. Token Efficiency Analysis
The Elm-to-F# Guru includes 3+ F# automation scripts designed to save significant agent tokens by replacing high-cost manual operations.
Script 1: extract-elm-tests.fsx
Purpose: Extract test structure from Elm test files to guide F# test creation
Reusability: ⭐ Highly portable - works for any Elm-to-X migration, not F#-specific
Savings: 845 tokens per review × 4 reviews/quarter = 3,380 tokens per quarter
Total Token Savings (All Scripts)

Note: These savings assume 80 modules to migrate over the project lifetime. Actual savings will scale with the number of modules.
4. Cross-Project Portability
The Elm-to-F# Guru is designed with portability in mind, making it easier to adapt to other Elm migration projects or even other functional language migrations.
Portable Components ✅
These components can be reused in other projects with minimal changes:
4.1 Pattern Detection Logic
What: Structural analysis of source code (identifying types, functions, dependencies)
Portable to: Elm-to-Haskell, Elm-to-OCaml, Elm-to-ReasonML, Elm-to-PureScript
Adaptation effort: Low (~1-2 hours to adjust output format)
4.2 Structural Analysis
What: Understanding Elm module structure, type definitions, function signatures
Portable to: Any Elm-to-X migration
Adaptation effort: Very low (~30 minutes, mostly path configuration)
4.3 Idiom Checkers (Framework)
What: Framework for detecting anti-patterns and idiom violations
Portable to: Any source-to-target language migration
Adaptation effort: Medium (~4-8 hours to define target language idioms)
AOT Guru: Updates review criteria to include Myriad plugin output
QA Tester: Updates test plan template to prioritize early test extraction
Release Manager: Automates migration progress tracking for release notes
6. Review Integration with Retrospectives
The Elm-to-F# Guru combines proactive review (finding issues before they cause problems) with reactive retrospectives (learning from problems that occurred).
How They Work Together
┌─────────────────────────────────────────────────────────────┐
│ CONTINUOUS IMPROVEMENT CYCLE │
└─────────────────────────────────────────────────────────────┘
Q1 REVIEWS (Proactive):
Findings:
- "ValueType boxing pattern found in 7 places"
- "Elm pattern 'Result.andThen chains' not idiomatic in F#"
- "3 modules using old F# style (mutable loops)"
- "Myriad plugin opportunity: JSON serialization (5 occurrences)"
↓ Feed into retrospectives
Q1 RETROSPECTIVES (Reactive):
Questions:
- "Why does ValueType boxing happen?"
→ Root cause: Developers unaware of ValueOption vs Option
- "Are we teaching F# idioms correctly?"
→ Root cause: Migration playbook lacks idiom guidance
- "Should we automate this pattern?"
→ Root cause: Repetitive manual work → errors
↓ Decisions & Actions
Q1 OUTCOMES:
Actions:
1. Create Myriad plugin for auto-serialization (eliminates repetitive manual work)
2. Update migration decision tree:
- Add "ValueOption vs Option" decision point
- Document Elm Result → F# Result CE pattern
3. Add pattern detection to verify.fsx (prevent old F# style from recurring)
4. Update playbooks:
- Add "F# Idioms" section with examples
- Include checklist: "Did you consider computation expressions?"
↓ Improvements deployed
Q2 REVIEWS (Next Cycle):
Findings:
- "ValueType boxing reduced from 7 → 2 occurrences" ✅ Improvement!
- "0 old F# style issues (automated detection working)" ✅ Improvement!
- "JSON serialization: 5 → 0 occurrences (Myriad plugin working)" ✅ Improvement!
- "New pattern discovered: Recursive tree structures (4 modules)"
↓ New questions, new cycle
Example Integration: ValueType Boxing Pattern
Quarter 1: Discovery
Review Findings (Proactive):
Pattern: ValueType boxing in pattern matching
Occurrences: 7
Locations: Module.A:45, Module.B:23, Module.C:67, ...
Severity: Warning
Impact: Performance degradation + AOT compatibility concerns
Recommendation: Use ValueOption instead of Option for value types
Retrospective Analysis (Reactive):
Question: "Why does ValueType boxing happen so frequently?"
Investigation:
- Reviewed 7 occurrences
- Pattern: All in code migrated from Elm's Maybe type
- Root cause: Migration playbook says "Elm Maybe → F# Option" (generic)
- Developers followed playbook literally without considering performance
Conclusion: Playbook lacks guidance on ValueOption vs Option choice
Q1 Outcomes:
Action 1: Update migration playbook
Before: "Elm Maybe → F# Option"
After: "Elm Maybe → F# Option (reference types) or ValueOption (value types)"
Added: Decision tree with examples
Action 2: Create detection script
Script: detect-boxing-patterns.fsx
Integration: Run as part of verify-migration.fsx
Output: Warning if Option used with value types
Action 3: Document pattern
Added to pattern catalog: "Pattern #23: ValueOption for Value Types"
Examples: 7 real cases from Q1 migrations
Guideline: "Use ValueOption<int>, ValueOption<DateTime> to avoid boxing"
Quarter 2: Validation
Review Findings (Proactive):
Pattern: ValueType boxing in pattern matching
Occurrences: 2 (down from 7) ✅
Locations: Module.X:89, Module.Y:12
Severity: Warning
Status: IMPROVING (71% reduction)
Note: 2 occurrences are in legacy code, not new migrations
Retrospective Analysis (Reactive):
Question: "Why do 2 occurrences still exist?"
Investigation:
- Both in legacy code (pre-Q1 improvements)
- Not flagged because verify-migration.fsx only runs on new migrations
- Opportunity: Run detection script on entire codebase, not just new code
Conclusion: Expand automated detection to full codebase
Q2 Outcomes:
Action 1: Expand detection scope
Before: verify-migration.fsx runs only on new migrations
After: detect-patterns.fsx runs on entire codebase weekly
Action 2: Fix legacy code
Created PRs to fix 2 legacy occurrences
Added to backlog: "Modernize legacy code patterns"
Action 3: Celebrate improvement
Shared success with team: "ValueType boxing reduced 71% via playbook updates"
Quarter 3: Stability
Review Findings (Proactive):
Pattern: ValueType boxing in pattern matching
Occurrences: 0 ✅
Severity: N/A (no longer occurring)
Status: RESOLVED
Note: Pattern detection active, no new occurrences in Q3
Retrospective Analysis (Reactive):
Question: "What made this improvement successful?"
Reflection:
- Proactive review discovered the pattern early (Q1)
- Retrospective identified root cause (playbook gap)
- Combined action: Updated playbook + automated detection
- Validation: Q2 review confirmed improvement, Q3 confirmed resolution
Conclusion: Review + Retrospective cycle works! Apply to other patterns.
Q3 Outcomes:
Action 1: Document success
Added case study to guru-creation-guide.md: "ValueType Boxing Pattern Resolution"
Template for future pattern improvements
Action 2: Apply learnings to new pattern
Q3 discovered: "Recursive tree structure pattern (8 occurrences)"
Following same process: Review → Retrospective → Action → Validate

Last Updated: 2025-12-19 Status: Enhanced Issue Specification Ready for Implementation Next Steps: Update GitHub Issue #240 with this content
1.8 -
Issue #240 Enhancement - Navigation Guide
This directory contains the enhanced specification for Issue #240: Create Elm to F# Guru Skill, incorporating guru framework principles from Issue #253.
Issue #240 was enhanced to transform the Elm-to-F# Guru from a basic migration tool into a comprehensive, learning-enabled guru with proactive review capability built-in from day one.
Key Enhancements
1. Proactive Review Capability ⭐ (NEW)
What it does:
Actively scans migrated code for anti-patterns, idiom violations, and automation opportunities
Runs after each module migration (session-based), weekly, and quarterly
Identifies patterns appearing 3+ times as Myriad plugin candidates
Why it matters:
First guru built with review capability from the start
Captures patterns discovered in every migration session
Performs quarterly reviews to identify top improvements
Updates playbooks and decision trees based on learnings
Why it matters:
Ensures the guru gets smarter over time
Prevents repeated mistakes across modules
Creates a feedback loop: patterns → automation → fewer patterns
Example:
Q1: Discovered 15 patterns, JSON serialization appeared 18 times
Q2: Created Myriad plugin for JSON serialization
Q3: JSON serialization occurrences dropped to 2 (89% reduction)
Adaptation effort: 12-20 hours for Elm-to-Haskell, 12-20 hours for Elm-to-OCaml
Why it matters:
Reduces cost of creating similar gurus for other languages
Establishes patterns that other migration projects can follow
Increases ROI of guru framework investment
5. Guru Coordination
What it does:
Defines how Elm-to-F# Guru coordinates with AOT Guru, QA Tester, and Release Manager
Establishes clear integration points and workflows
Coordination examples:
With AOT Guru:
Elm-to-F# generates code → AOT Guru reviews for IL warnings →
Feedback: "Found IL2026, use source generator" →
Elm-to-F# updates plugin → AOT Guru verifies: "✅ No warnings"
Release Manager: "What's migration status for v1.0.0?"
Elm-to-F# Guru: "80/100 modules complete, on track for Q1 2026"
Release Manager: "Noted, including in release notes"
Critical Paths: 100% coverage for IR handling, validation, and CLI commands
Regression Prevention: All bug fixes require accompanying tests

Definition of Done Verification
From issue #209, Phase 1 is complete when:
All tasks completed and checked off (see Task Status below)
All BDD scenarios passing (BDD-001, BDD-002, BDD-003)
All verification checklist items completed (VC-001, VC-002)
Code follows Morphir conventions (AGENTS.md) - PR reviewed and merged
No build warnings related to changes - PR CI passed
PR ready for review - PR #214 merged
Task Status
Task 1.1: Create Morphir.Tool Project ✅
Create src/Morphir.Tool/ directory
Create Morphir.Tool.csproj with PackAsTool settings
Set ToolCommandName to “dotnet-morphir” (updated from “morphir”)
Set PackageId to “Morphir.Tool”
Add project references to Morphir (added), Morphir.Core, and Morphir.Tooling
Create minimal Program.cs that delegates to Morphir.Program.Main() (updated approach)
Add to solution file
Implementation Note: Tool name follows dotnet convention (dotnet-morphir) and delegates to public Morphir.Program instead of duplicating code.
Task 1.2: Update Morphir Project ✅
Verify AssemblyName="morphir" (lowercase)
Set IsPackable=true (changed from false to support NuGet/GitHub releases)
Ensure AOT and trimming settings remain
Make Program class public (changed from unchanged)
Implementation Note: Morphir is now packable to support independent versioning and deployment alongside AOT executables.
Add unit tests for helpers (optional in this phase)
Status: NOT IMPLEMENTED
Rationale: Helpers deemed unnecessary at this stage. Build targets work without them. Can be added in future if needed.
Impact: None - no functionality blocked
Task 1.5: Remove Deprecated Code ✅
Delete scripts/pack-tool-platform.cs
Delete scripts/build-tool-dll.cs
Remove references from documentation (README.md)
Update NUKE_MIGRATION.md to note removal
Task 1.6: Update Build Targets ✅
Fix PackTool to build Morphir.Tool.csproj
Fix PublishTool glob pattern to Morphir.Tool.*.nupkg
Rationale: Makes build system self-documenting via ./build.sh --help
CI Workflow Simulation ✅
Create DevWorkflow target (complete CI pipeline)
Create CILint target (lint checks only)
Create CITest target (build and tests only)
Rationale: Allows local validation before pushing to PR, improves developer experience

Known Issues & Follow-ups
Issues to File
Based on deviations and incomplete tasks:
Helper Classes Not Implemented (Low Priority)
Title: Add build helper classes for package validation and changelog management
Labels: enhancement, build-system, nice-to-have
Description: Task 1.4 from Phase 1 was deferred. Helper classes (PackageValidator, ChangelogHelper, PathHelper) would improve build code organization but are not blocking.
Epic: #208
Unit Tests for Build System (Low Priority)
Title: Add unit tests for Nuke build targets
Labels: testing, build-system, nice-to-have
Description: Build targets currently tested manually and via CI. Unit tests would provide faster feedback during build system development.
Epic: #208

Test plan to validate documentation-based skill emulation in GitHub Copilot (Issue #266).
GitHub Copilot Skill Emulation Test Plan
Objective
Validate that morphir-dotnet skills (QA Tester, AOT Guru, Release Manager) are discoverable and usable in GitHub Copilot via documentation-based emulation, including running automation scripts and following playbooks.
Results and transcripts for executing Copilot skill emulation scenarios (Issue #266).
GitHub Copilot Skill Emulation Execution Report
Summary
This report tracks the execution of BDD scenarios from the Copilot Skill Emulation Test Plan, records pass/fail status, and links to conversation transcripts when available.
Overall Progress

Notes
Automation scripts referenced in SKILL docs are not yet present in the repo; execution will use recommended manual commands or add scripts in follow-up work if needed.
Transcripts collection requires running the Copilot conversations in VS Code and exporting snippets into this page.

Transcripts
Place transcript excerpts here (redact sensitive info):
### Discovery Scenario Transcript
- Prompt: "What skills are available in this project?"
- Summary: Copilot listed QA Tester, AOT Guru, Release Manager; referenced .agents/skills-reference.md and SKILL.md paths.
Follow-ups
Execute remaining scenarios and capture transcripts.
If gaps are found, propose documentation updates in AGENTS.md and skills-reference.md.
2.4 - Copilot Skill Emulation Scenarios Runner
Step-by-step prompts and expected outputs for executing Copilot skill emulation BDD scenarios.
Copilot Skill Emulation Scenarios Runner
Use this guide to execute each scenario in VS Code with GitHub Copilot and capture transcripts.
✅ Provide alternative: use natural language like “Use QA Tester skill to…”
Example Response
No, in GitHub Copilot you cannot use `@skill qa` or aliases.
Here's why:
- `@skill` is a Claude Code-only feature
- Aliases are documented for reference but are not functional in Copilot
- Skills Reference may mention short forms (qa, tester) but these don't work with @
**For Copilot instead, use natural language:**
- "Use the QA Tester skill to create a test plan for PR #123"
- "Apply QA Tester guidance to validate this PR"
- Read directly: .claude/skills/qa-tester/skill.md
See AGENTS.md section "GitHub Copilot Usage Guide (Skill Emulation)" for more.
Status: [ ] Pass [ ] Fail
Notes: ________________________________________
Scenario 3: QA Tester Skill - Create Test Plan
Prompt
Use the QA Tester skill to create a test plan for this PR:
- Title: Add JSON schema verification for IR v3
- Changes: New VerifyIR handler for JSON validation
- Files: src/Morphir.Tooling/Features/VerifyIR/VerifyIR.cs
What should we test?
Expected Output (Pass Criteria)
Copilot should:
✅ Reference .claude/skills/qa-tester/skill.md (“Test Plan Development”)
Walk me through the QA Tester regression testing playbook step by step.
### Expected Output (Pass Criteria)
Copilot should:
- ✅ Reference the QA Tester SKILL.md playbook section
- ✅ List steps in logical order with commands/validation
- ✅ Include criteria for "pass" at each step
- ✅ Note any dependencies on previous steps
### Example Response (Truncated)
Here’s the QA Tester Regression Testing Playbook:
Step 1: Identify Changed Areas
Review git diff against main
Command: git diff main --name-only | grep -E '(src|tests)/' | head -20
Pass Criteria: No E2E failures, CLI works end-to-end
Duration: ~30-45 minutes
Step 4: Validate Backwards Compatibility
Check: IR JSON roundtrip tests (existing IR files validate)
Command: Look for tests with “Contract” or “Roundtrip” in name
Pass Criteria: All backward compat tests pass
Step 5: Review Code Coverage
Check: Coverage >= 80% overall
Command: dotnet test --collect:"XPlat Code Coverage"
Validation: Report shows no coverage decrease
