What Changed

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
• Prevents technical debt before it accumulates
• Drives automation decisions (patterns → plugins)

Example output:

Pattern Frequency Report:
- ValueType boxing: 7 occurrences → Recommend Myriad plugin
- Manual JSON serialization: 5 occurrences → Consider automation
- Migration quality: 82% idiom compliance (target: 80%) ✅

2. Automated Feedback & Continuous Improvement

What it does:

• 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)

3. Token Efficiency Analysis

What it does:

• Provides 4 F# automation scripts targeting high-token-cost tasks
• Documents token savings per script with annual projections

Scripts:

1. extract-elm-tests.fsx - Extract test structure from Elm (saves ~420 tokens/module)
2. analyze-elm-module.fsx - Structural analysis for translation planning (saves ~555 tokens/module)
3. verify-migration.fsx - Validate F# against Elm source (saves ~765 tokens/module)
4. detect-patterns.fsx - Find anti-patterns and idiom violations (saves ~845 tokens/review)

Total savings: ~152,720 tokens annually (80 modules)

Why it matters:

• Automation scripts are reusable across projects (not just morphir-dotnet)
• Significant efficiency gains for AI agents
• Clear ROI for guru creation effort

4. Cross-Project Portability

What it does:

• Documents which components are portable to other Elm-to-X migrations
• Provides adaptation guides for Elm-to-Haskell, Elm-to-OCaml, etc.

Portable components:

• ✅ Pattern detection logic (works for any Elm source)
• ✅ Structural analysis (Elm module parsing)
• ✅ Review philosophy (applies to all gurus)
• ✅ Automation script framework (F# script structure)

Non-portable components:

• ⚠️ F#-specific idioms
• ⚠️ Myriad plugins (F#-specific tool)
• ⚠️ Type mappings (Elm → F# specific)

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"

With QA Tester:

Elm-to-F# migrates module → QA Tester checks coverage →
Feedback: "10/12 tests, missing 2 edge cases" →
Elm-to-F# adds tests → QA Tester: "✅ 12/12 coverage"

With Release Manager:

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"

Why it matters:

• No guru works in isolation
• Cross-guru coordination ensures quality
• Shared retrospectives drive project-wide improvements

6. Review Integration with Retrospectives

What it does:

• Shows how proactive reviews and reactive retrospectives work together
• Provides Q1-Q3 example of the improvement cycle

Cycle:

Q1 Reviews (Proactive): "Found 7 ValueType boxing patterns"
   ↓
Q1 Retrospectives (Reactive): "Why? Playbook lacks ValueOption guidance"
   ↓
Q1 Outcomes: Update playbook, create detection script
   ↓
Q2 Reviews: "Boxing reduced from 7 → 2 (71% improvement)"
   ↓
Q3 Reviews: "Boxing at 0, pattern resolved"

Why it matters:

• Reviews find issues early (prevent problems)
• Retrospectives find root causes (prevent recurrence)
• Together they create a continuous improvement cycle

7. Enhanced Success Criteria

What it does:

• Defines success across 4 dimensions: Functional, Learning, Automation, Maturity
• Establishes 3 maturity phases: Alpha, Beta, Stable

Maturity phases:

Success metrics:

• Modules migrated: 10 → 40 → 80
• Patterns documented: 15 → 20 → 25+
• Myriad plugins: 0 → 2-3 → 5+
• Token savings: Baseline → ~75K → ~150K annually

Why it matters:

• Clear roadmap for guru evolution
• Measurable progress indicators
• Time-bound expectations (quarterly milestones)

Comparison: Before vs After Enhancement
