FlashRAG Evidence (VCO)

When to use

Use this skill when you need grounded, citeable evidence from local documentation/configuration to support VCO decisions or recommendations, especially for:

• VCO routing / pack selection rationale
• Protocol compliance (think/do/review/team/retro)
• Config semantics (thresholds, overlays, governance)
• “Show me where this rule comes from” / “give me the exact snippet”

This skill is not a replacement for GitNexus (code dependency graph) or web search. It focuses on local docs and config.

Inputs

• Query: what you’re trying to verify (short, concrete)
• Optional: corpus root(s) to search (defaults below)

Default corpus (evidence plane)

1. VCO core docs/config inside ~/.codex/skills/vibe/:
   • protocols/, config/, references/, scripts/router/
2. Skills catalog (~/.codex/skills/**/SKILL.md) for tool capability evidence
3. (Optional) Project-local VCO overlays under the current workspace, if present

Workflow (Lite, no heavy deps)

1. Run the evidence retriever script:

   • Windows PowerShell:
     • python C:\Users\羽裳\.codex\skills\flashrag-evidence\scripts\flashrag_evidence.py --query "…" --topk 8

2. (Optional) Enable a faster FlashRAG-style BM25 backend (bm25s)

   • Preflight (checks vendoring + env; does NOT read secrets):
     • pwsh C:\Users\羽裳\.codex\skills\vibe\scripts\ruc-nlpir\preflight.ps1
   • Manually create an isolated venv for the vendored runtime and install only the minimal packages you need. The old install-upstreams.ps1 auto-install path has been removed on purpose.
   • Use bm25s engine:
     • C:\Users\羽裳\.codex\_external\ruc-nlpir\.venv\Scripts\python.exe C:\Users\羽裳\.codex\skills\flashrag-evidence\scripts\flashrag_evidence.py --engine bm25s --query "…" --topk 8

3. Use the returned snippets as P5 evidence:

   • [Command] the exact command you ran
   • [Output] the top snippets (path + line anchor)
   • [Claim] the conclusion you draw (only what the evidence supports)

4. If coverage is low:

   • Expand --roots to include the project workspace
   • Increase --topk
   • Fallback: targeted rg -n on the most likely file(s)

Outputs

The script prints ranked evidence items:

• path + line (1-based) for quick navigation
• score for ranking
• snippet (short, safe to quote)

Notes (non-redundancy)

• If you need code call chains / blast radius, use GitNexus overlays (not this).
• If you need latest web facts, use web search / deep research tools (not this).
