# Dependency graph
requires:
  - phase: 01-core-infrastructure
    provides: Project workspace and session management foundation
provides:
  - OpenClaw skill definition with valid YAML frontmatter
  - /gsd:* command trigger patterns for skill invocation
  - Documentation of all supported GSD commands
affects: [03-orchestration, 04-commands]

# Tech tracking
tech-stack:
  added: [pyyaml]
  patterns: [YAML frontmatter, skill trigger patterns]

key-files:
  created:
    - skill/SKILL.md
    - tests/test_skill_md.py
  modified: []

key-decisions:
  - "SKILL.md uses only /gsd:* command triggers, no natural language"
  - "Description field contains explicit /gsd: pattern for OpenClaw matching"

patterns-established:
  - "YAML frontmatter between --- delimiters for skill metadata"
  - "name and description fields required for OpenClaw skill loading"

# Phase 2 Plan 1: SKILL.md Definition Summary

**OpenClaw skill definition with YAML frontmatter, /gsd:* trigger patterns, and comprehensive command documentation for GSD project management**

## Performance

- **Duration:** 3 min
- **Started:** 2026-03-11T05:00:00Z
- **Completed:** 2026-03-11T05:02:46Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments

- Created SKILL.md with valid YAML frontmatter (name, description fields)
- Documented all supported /gsd:* commands in command table
- Established trigger pattern for OpenClaw skill matching (/gsd: in description)
- Added comprehensive tests for SKILL.md structure validation

## Task Commits

Each task was committed atomically:

1. **Task 1: Create test scaffold for SKILL.md validation** - `10c24c9` (test)
2. **Task 2: Create SKILL.md with valid frontmatter** - `6ef9f94` (feat)

_Note: TDD flow - test commit (RED) then implementation commit (GREEN)_

## Files Created/Modified

- `skill/SKILL.md` - OpenClaw skill definition with YAML frontmatter and command documentation
- `tests/test_skill_md.py` - Tests for SKILL.md structure and trigger pattern validation

## Decisions Made

None - followed plan as specified. All decisions were locked in CONTEXT.md:
- Only /gsd:* command triggers (no natural language)
- Description contains explicit /gsd: pattern for trigger matching

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

- PyYAML was not in venv dependencies - added via `uv add pyyaml --dev`

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- SKILL.md ready for OpenClaw skill loading
- Tests ensure frontmatter remains valid
- Ready for Phase 2 Plan 02 (Response Formatter) and Plan 03 (Prompt Templates)
