Skill Curator
Autonomous skill lifecycle system. Works in partnership with skill-compounder to close the loop: observe -> draft -> review -> promote.
The Pipeline
1. You work normally (no manual action needed)
2. skill-compounder (Stop hook) detects successful patterns
3. Draft written to ~/.claude/skills-drafts/
4. skill-curator (SessionStart hook) reviews all drafts
5. Drafts are either:
- PROMOTED to ~/.claude/skills/ (confidence >= 80, no duplicates)
- MERGED with existing similar skill
- ARCHIVED to ~/.claude/skills-drafts/archive/ (confidence < 50)
- KEPT in drafts for next review (50-79, needs more evidence)Promotion Criteria
A draft is auto-promoted when ALL of these are true:
| Criterion | Threshold | |-----------|-----------| | Confidence | >= 80 | | Occurrences | >= 3 (or category is error-recovery) | | Uniqueness | Not duplicate of existing skill | | Age | Less than 14 days old | | Category | One of: repeated-workflow, error-recovery, domain-pattern |
Archive Criteria
A draft is auto-archived when ANY of these are true:
- Confidence < 50 (not reproducible)
- Age > 14 days without promotion (stale)
- Duplicate of existing promoted skill
Duplicate Detection
Before promoting, check against existing skills:
- Name match - exact directory name
- Category + description overlap - same category, 4+ keyword overlap
If duplicate found, either merge evidence into existing skill or archive.
Draft File Format
Drafts live in ~/.claude/skills-drafts/<name>.md:
---
name: pattern-abc123
description: "Procedural pattern: Read -> Edit -> Test -> Commit"
category: repeated-workflow
confidence: 85
occurrences: 7
source_session: s-xyz789
generated_at: 2026-04-12T03:45:00Z
status: draft
---When promoted, status: draft becomes status: active.
Integration
- skill-compounder (Stop hook): Generates drafts from session observations
- self-learner: Provides error-pattern data that feeds skill-compounder
- canavar: Cross-trains all agents when skill is promoted
- layered-recall: Makes new skills queryable via Depth 1-3 pattern
Metrics
Tracked in ~/.claude/skill-evolution.jsonl:
- draft_generated_at
- promoted_at
- time_to_promotion
- usage_after_promotion
- retention_rate (still active after 30 days)
Safety
- No manual override needed - runs silently on session start
- No destructive actions - drafts/skills are moved, not deleted
- Rollback via git - all promoted skills are in git history
- High threshold - 80+ confidence prevents low-quality promotion
