feat(M4.1): Add mem skill draft CLI command with integration tests
Adds command to generate SKILL.md drafts from memory notes:
Files modified:
crates/mem-cli/src/main.rs
- Add SkillCommand enum with Draft variant
- Add Commands::Skill variant to Commands enum
- Add cmd_skill_draft() handler function
- Parse project/query-id input
- Generate SKILL.md with YAML frontmatter
- Include name, description, when_to_use fields
- Include generated_from: <sha> provenance
- Include generated_at: <timestamp>
- Support --dry-run flag (print without writing)
- Enforce _drafts/ directory (no direct skills/ writes)
- Create directory structure automatically
Files created:
tests/it_skill_draft.rs
- 7 unit tests (all passing):
a1: Parses input format (project/query-id)
a2: Rejects invalid formats (wrong separators, empty)
a3: Creates _drafts directory structure
a4: Generates YAML frontmatter with all required fields
a5: Includes generated_from provenance link
a6: Enforces _drafts/ directory (not skills/)
a7: Dry-run mode doesn't write files
Status:
✓ All 7 tests pass
✓ Command works end-to-end (tested manually)
✓ Dry-run mode verified
✓ Directory enforcement working
Next (TODO in code):
- Read L1/L2 memory node from database
- Use LLM to convert descriptive → procedural memory
- Retrieve real sha256 from memory_node (replace placeholder)
- Skill authoring rubric in LLM prompt (name, description, when_to_use)
Blocks: M4.2 (cycle guard), M4.3 (gate)
Depends: M3.4 ✓ (composition gate)
