doc-lookup

name	doc-lookup
description	Unified documentation lookup for Bug Hunter agents. Uses Context Hub (chub) as primary source with Context7 API fallback. Provides verified library/framework documentation to prevent false positives and ensure correct fix patterns.

Doc Lookup — Verified Documentation Access

Documentation Lookup (Context Hub + Context7 fallback)

When you need to verify a claim about how a library, framework, or API actually behaves — do NOT guess from training data. Look it up.

When to use this

• "This framework includes X protection by default" — verify it
• "This ORM parameterizes queries automatically" — verify it
• "This function validates input" — verify it
• "The docs say to do X" — verify it
• Any claim about library behavior that affects your bug verdict

How to use it

SKILL_DIR is injected by the orchestrator. Use it for all helper script paths.

The lookup script tries Context Hub (chub) first for curated, versioned docs, then falls back to Context7 when chub doesn't have the library.

Step 1: Search for the library

node "$SKILL_DIR/scripts/doc-lookup.cjs" search "<library>" "<what you need to know>"

Example: node "$SKILL_DIR/scripts/doc-lookup.cjs" search "prisma" "SQL injection parameterized queries"

This returns results from both sources with a recommended_source and recommended_id.

Step 2: Fetch documentation

node "$SKILL_DIR/scripts/doc-lookup.cjs" get "<library-or-id>" "<specific question>"

Example: node "$SKILL_DIR/scripts/doc-lookup.cjs" get "prisma/orm" "are raw queries parameterized by default"

This fetches curated docs from chub if available, otherwise Context7 documentation snippets with code examples.

Optional flags:

• --lang js|py — language variant (for chub docs with multiple languages)
• --source chub|context7 — force a specific source

Rules

• Only look up docs when you have a SPECIFIC claim to verify. Do not speculatively fetch docs for every library in the codebase.
• One lookup per claim. Don't chain 5 searches — pick the most impactful one.
• If the API fails or returns nothing useful, say so explicitly: "Could not verify from docs — proceeding based on code analysis."
• Cite what you found: "Per Express docs: [quote]" or "Prisma docs confirm that $queryRaw uses parameterized queries."
