Agent Skills: Skill Idea Miner

Skill Idea Miner

Automatically extract skill idea candidates from Claude Code session logs, score them for novelty, feasibility, and trading value, and maintain a prioritized backlog for downstream skill generation.

When to Use

• Weekly automated pipeline run (Saturday 06:00 via launchd)
• Manual backlog refresh: python3 scripts/run_skill_generation_pipeline.py --mode weekly
• Dry-run to preview candidates without LLM scoring

Workflow

Stage 1: Session Log Mining

1. Enumerate session logs from allowlist projects in ~/.claude/projects/
2. Filter to past 7 days by file mtime, confirm with timestamp field
3. Extract user messages (type: "user", userType: "external")
4. Extract tool usage patterns from assistant messages
5. Run deterministic signal detection:
   • Skill usage frequency (skills/*/ path references)
   • Error patterns (non-zero exit codes, is_error flags, exception keywords)
   • Repetitive tool sequences (3+ tools repeated 3+ times)
   • Automation request keywords (English and Japanese)
   • Unresolved requests (5+ minute gap after user message)
6. Invoke Claude CLI headless for idea abstraction
7. Output raw_candidates.yaml

Stage 2: Scoring and Deduplication

1. Load existing skills from skills/*/SKILL.md frontmatter
2. Deduplicate via Jaccard similarity (threshold > 0.5) against:
   • Existing skill names and descriptions
   • Existing backlog ideas
3. Score non-duplicate candidates with Claude CLI:
   • Novelty (0-100): differentiation from existing skills
   • Feasibility (0-100): technical implementability
   • Trading Value (0-100): practical value for investors/traders
   • Composite = 0.3 * Novelty + 0.3 * Feasibility + 0.4 * Trading Value
4. Merge scored candidates into logs/.skill_generation_backlog.yaml
