name: skill-retrieval description: | Semantic search over skill libraries using ColBERT embeddings. Use when:

• "find a skill for..." or "search for skills that..."
• "what skill handles..." or "which skill can..."
• "index my skills" or "rebuild the skill index"
• "show me relevant skills for this task" allowed-tools:

Skill Retrieval System

ColBERT-based semantic search over skill libraries.

Quick Start

Copy# Build the index (one-time, ~30s per skill with LLM analysis)
voyager skill index --verbose

# Search for skills
voyager skill find "resume where we left off"
voyager skill find "what should I work on next"
voyager skill find "turn this workflow into a skill"

CLIs

voyager skill index

Build or update the skill search index.

Copyvoyager skill index [OPTIONS]

Options:

• --paths PATH — Additional skill directories to index
• --output DIR — Index location (default: ~/.skill-index/)
• --rebuild — Force rebuild from scratch
• --skip-llm — Skip LLM analysis (faster but lower quality)
• -v, --verbose — Show progress

voyager skill find

Search for relevant skills.

Copyvoyager skill find "your query" [OPTIONS]

Options:

• -k, --top-k N — Number of results (default: 5)
• --index DIR — Index location
• --json — Output as JSON

Index Locations

• Default: ~/.skill-index/
• Override via VOYAGER_SKILL_INDEX_PATH env var
• Local dogfooding: --output ./.claude/voyager/skill-index/

Skill Sources

Auto-discovers skills from:

• Plugin skills: ./skills/
• Local mirror: ./.claude/skills/local/
• Generated skills: ./.claude/skills/generated/
• User skills: ~/.claude/skills/

Override with CLAUDE_SKILLS_PATH env var.

How It Works

1. Discovery: Find all SKILL.md files in known locations
2. Analysis: Use LLM to extract metadata (purpose, triggers, capabilities)
3. Embedding: Generate searchable text from metadata
4. Indexing: Build ColBERT index for fast semantic search

Indexing happens once; search is instant (no LLM calls).
