## What this skill does

- RAG v2 core: incremental ingest + hash cache, BM25 lexical retrieval, heuristic multi-query + step-back, overlap rerank, max context cap
- Advanced adapters (skeletons): GraphRAG / RAPTOR / CRAG pipelines (offline-first defaults)
- Governance outputs: report JSON, claims ledger (E2), EvidencePack (E3 bundle)

## CLI usage (repo root)

```bash
export PYTHONPATH="$PWD/.shared/vibe-coder-v13:${PYTHONPATH:-}"

# Build / update KB (skips unchanged docs)
python3 .shared/vibe-coder-v13/vibe.py rag ingest \
  --spec .vibe/inputs/v13/rag_spec.yml \
  --kb .vibe/kb

# Query
python3 .shared/vibe-coder-v13/vibe.py rag query \
  --kb .vibe/kb \
  --q "your question" \
  --max-context-chars 24000

# Eval (report + claims + evidencepack)
python3 .shared/vibe-coder-v13/vibe.py rag eval \
  --kb .vibe/kb \
  --eval .vibe/inputs/v13/rag_eval.yml \
  --out .vibe/reports/rag-eval.json \
  --evidencepack-out .vibe/evidencepacks
```
