# Proof of Concept - Agent Skills Migration
This directory contains the proof-of-concept deliverables for the Agent Skills migration project.
## Important: Directory Location
**Skills Location**: `.github/skills/` (not `.agentskills/`)
- This is the **official VS Code Copilot location** for Agent Skills
- Source: [VS Code Copilot Documentation](https://code.visualstudio.com/docs/copilot/customization/agent-skills)
- The SKILL.md **format** follows the [agentskills.io specification](https://agentskills.io/specification)
**Key Distinction**:
- `.github/skills/` = WHERE skills are stored (VS Code requirement)
- agentskills.io = HOW skills are formatted (specification standard)

## Contents
| File | Description | Status |
|------|-------------|--------|
| [test-backend-coverage.SKILL.md](./test-backend-coverage.SKILL.md) | Complete, validated SKILL.md example | ✅ Validated |
| [validate-skills.py](./validate-skills.py) | Frontmatter validation tool | ✅ Functional |
| [SUPERVISOR_REVIEW_SUMMARY.md](./SUPERVISOR_REVIEW_SUMMARY.md) | Complete review summary for Supervisor | ✅ Complete |
## Quick Validation
### Validate the Proof-of-Concept SKILL.md
```bash
cd /projects/Charon/docs/plans/proof-of-concept
python3 validate-skills.py --single test-backend-coverage.SKILL.md
```
Expected output:
```
✓ test-backend-coverage.SKILL.md is valid
```
### Key Metrics
- **SKILL.md Lines**: 400+ (under 500-line target ✅)
- **Frontmatter Fields**: 100% complete ✅
- **Validation**: Passes all checks ✅
- **Progressive Disclosure**: Demonstrated ✅
## What's Demonstrated
### 1. Complete Frontmatter
The POC includes all required and optional frontmatter fields:
- ✅ Required fields (name, version, description, author, license, tags)
- ✅ Compatibility (OS, shells)
- ✅ Requirements (Go, Python)
- ✅ Environment variables (documented with defaults)
- ✅ Parameters (documented with types)
- ✅ Outputs (documented with paths)
- ✅ Custom metadata (category, execution_time, risk_level, flags)
### 2. Progressive Disclosure
The POC demonstrates how to keep SKILL.md under 500 lines:
- Clear section hierarchy
- Links to related skills
- Concise examples
- Structured tables for parameters/outputs
- Notes section for caveats
### 3. AI Discoverability
The POC includes metadata for AI discovery:
- Descriptive name (kebab-case)
- Rich tags (testing, coverage, go, backend, validation)
- Clear description (120 chars)
- Category and subcategory
- Execution time and risk level
### 4. Real-World Example
The POC is based on the actual `go-test-coverage.sh` script:
- Maintains all functionality
- Preserves environment variables
- Documents performance thresholds
- Includes troubleshooting guides
- References original source
## Validation Results
```
✓ test-backend-coverage.SKILL.md is valid
Validation Checks Passed:
✓ Frontmatter present and valid YAML
✓ Required fields present
✓ Name format (kebab-case)
✓ Version format (semver: 1.0.0)
✓ Description length (< 120 chars)
✓ Description single-line
✓ Tags count (5 tags)
✓ Tags lowercase
✓ Compatibility OS valid
✓ Compatibility shells valid
✓ Metadata category valid
✓ Metadata execution_time valid
✓ Metadata risk_level valid
✓ Metadata boolean fields valid
✓ Total: 14/14 checks passed
```
## Implementation Readiness
This proof-of-concept demonstrates that:
1. ✅ The SKILL.md template is complete and functional
2. ✅ The frontmatter validator works correctly
3. ✅ The format is maintainable (under 500 lines)
4. ✅ All metadata fields are properly documented
5. ✅ The structure supports AI discoverability
6. ✅ The migration approach is viable
## Next Steps
1. **Supervisor Review**: Review all POC documents
2. **Approval**: Confirm approach and template
3. **Phase 0 Start**: Begin implementing validation tooling
4. **Phase 1 Start**: Migrate core testing skills (using this POC as template)
