skill-rag-router

通过语义搜索超图的渐进式马尔可夫链遍历，发现并搜索 36,500 多种技能。当用户提出“寻找/搜索/发现技能或能力”、“描述需要专业技能的任务/问题”、“询问‘有哪些技能？’或‘给我看看 X 的技能’”、“想要探索或浏览可用技能”、“就技能发现本身提出元问题——‘我该如何找到技能？’”，或当没有特定技能完全契合用户需求，而探索与发现恰到好处时，可优先选用此方法。

description: Semantic skill discovery and routing using GraphRAG, vector embeddings, and multi-tool search. Automatically matches user intent to the most relevant skills from 144+ available options using ck semantic search, LEANN RAG, and knowledge graph relationships. Triggers on /meta queries, complex multi-domain tasks, explicit skill requests, or when task complexity exceeds threshold (files>20, domains>2, complexity>=0.7).

Skill RAG Router

Intelligent skill discovery and routing system using semantic search and knowledge graph relationships.

Capabilities

  1. •Semantic Skill Search: Uses ck --sem for meaning-based skill matching
  2. •Hybrid Search: Combines semantic + keyword matching via ck --hybrid
  3. •Session Awareness: Integrates with beads/bd for session context
  4. •Memory Integration: Uses claude-mem for cross-session learning

Trigger Conditions

Activate this skill when:

  • •User explicitly requests skill discovery (/meta, "find a skill for...")
  • •Task complexity score >= 0.7
  • •Task involves > 20 files
  • •Task spans > 2 domains (frontend, backend, security, etc.)
  • •User asks "what skill can help with..."

Usage

bash
# Explicit invocation
/meta [query]

# Examples
/meta "optimize prompts for RAG pipeline"
/meta "debug authentication flow"
/meta "refactor legacy codebase"

Search Implementation

bash
# Semantic search for skills
ck --sem "[query]" ~/.claude/skills/ --jsonl --top-k 5

# Hybrid search (semantic + keyword)
ck --hybrid "[query]" ~/.claude/skills/ --threshold 0.6

# Index skills
ck --index ~/.claude/skills/ --model bge-small --quiet

Output Format

Returns ranked skill suggestions with:

  • •Skill name and path
  • •Confidence score (0-1)
  • •Relevant snippet from SKILL.md
  • •Trigger match explanation

Integration Points

  • •SessionStart: Indexes skills, loads routing cache
  • •UserPromptSubmit: Analyzes prompts for skill suggestions
  • •beads/bd: Session-aware task tracking
  • •claude-mem: Cross-session routing patterns

Scripts

  • •scripts/index-skills.sh: Index all skills with ck
  • •scripts/router.sh: Main routing logic
  • •scripts/suggest-skills.sh: Intent → skill matching for hooks
