- **Status**: Near convergence (V_meta=0.709, V_instance=0.895)
- **Iterations**: 2 (Baseline + Design)
- **Duration**: ~4 hours

### Target Skill Location
- **Path**: `/home/yale/work/meta-cc/.claude/skills/subagent-prompt-construction/`
- **Integration**: meta-cc Claude Code plugin

## Protocol Upgrades Applied (v3.0)

### ✅ Meta Objective Parsing
- Parsed V_meta components from `config.json` and `results.md`
- Extracted weights, priorities, targets, and enforcement levels
- Generated dynamic constraints based on meta_objective

### ✅ Dynamic Constraints Generation
- **Compactness**: SKILL.md ≤40 lines, examples ≤150 lines
- **Integration**: ≥3 Claude Code features
- **Generality**: 3+ domains (1 validated, 3+ designed)
- **Maintainability**: Clear structure, cross-references
- **Effectiveness**: V_instance ≥0.85

### ✅ Meta Compliance Validation
- Generated `inventory/compliance_report.json`
- Validated against all 5 meta_objective components
- Calculated V_meta compliance (0.709, near convergence)

### ✅ Config-Driven Extraction
- Honored `extraction_rules` from `config.json`:
  - `examples_strategy: "compact_only"` → examples ≤150 lines
  - `case_studies: true` → detailed case studies in reference/
  - `automation_priority: "high"` → 4 automation scripts

### ✅ Three-Layer Structure
- **Layer 1 (Compact)**: SKILL.md (38 lines) + examples/ (86 lines)
- **Layer 2 (Reference)**: patterns.md, integration-patterns.md, symbolic-language.md
- **Layer 3 (Deep Dive)**: case-studies/phase-planner-executor-analysis.md

## Warnings

1. **V_meta (0.709) below threshold (0.75)**: Near convergence, pending cross-domain validation
2. **Only 1 domain validated**: Orchestration domain validated, 3+ domains designed

## Recommendations

### For Immediate Use ✅
- Template structure ready for production
- Integration patterns ready for production
- Symbolic language syntax ready for production
- Compactness guidelines ready for production
- phase-planner-executor example ready as reference

### For Full Convergence (+0.041)
1. **Practical validation** (1-2h): Test phase-planner-executor on real TODO.md
2. **Cross-domain testing** (3-4h): Apply to 2 more diverse domains
3. **Template refinement** (1-2h): Create light template variant

**Estimated effort to convergence**: 6-9 hours
