Skill

source-grounding

Verify version-sensitive facts against live authoritative sources before asserting them in code or answers. Triggers on: "/source-grounding", "source-grounding", "sourcing". Standing rule — always active via CLAUDE.md. Invoke for deep verification work (API signatures, CVEs, model IDs, auth flows, deprecated patterns, security advisories).

Source Grounding

Standing rule — active every response. No invocation needed for routine use.

What to verify (not memory)

CRITICAL (always fetch or flag): API/SDK call signatures · library versions & deprecations · CVEs/security advisories · auth/crypto specs · LLM model IDs & params
MEDIUM (verify when unsure): package names · config keys · CLI flags · protocol specs
LOW/stable: math, algorithms, language syntax → memory fine

How

Identify the version-sensitive claim.
Name the authoritative source (official docs, advisory DB, package registry, spec, source code).
Fetch (WebSearch/WebFetch/docs MCP) — or flag ⚠️ unverified: check [source].
Cite at CRITICAL/MEDIUM. Don't over-verify stable facts.

Per-claim-type authoritative source map: read references/sources.md when choosing where to verify.

Source hierarchy

Source code / spec / RFC — primary ground truth
Official/vendor docs — authoritative secondary (honor .coalmine.json trustedDomains if set: treat those domains as additional authoritative / tier-2 sources)
Multiple reputable third-party sources — triangulated
Single blog — weak; corroborate first
Training memory — weakest for volatile facts

Non-interactive runs: log unfetchable claims as ⚠️ UNVERIFIED and continue — never block. Interactive: when sources cannot be fetched, confirm how to proceed via ask_question.

Output

Verified: ✅ [claim] — source: [link/file]
Unverified: ⚠️ unverified — check [exact source]
Stable fact: no annotation needed

AUTHORITATIVE vs DIVERSE

AUTHORITATIVE (one ground truth): API/version/config/spec → go to the actual source code or official docs.
DIVERSE (triangulate ≥ 3): "what's best" / landscape / patterns → multiple repos + docs + community; note conflicts.

Verifies version-sensitive and time-changing facts (APIs, configs, CLI flags, pricing, model IDs) against installed environment and current docs before relying on training memory.

Selectively requires citations for high-value factual claims to balance accuracy with token cost. Use before research tasks or when deciding whether a claim needs verification.
