Verify version-sensitive facts against live authoritative sources before asserting them in code or answers. Triggers on: "/source-grounding", "source-grounding", "sourcing". Standing rule where your CLAUDE.md or AGENTS.md carries it. Invoke for deep verification work (API signatures, CVEs, model IDs, auth flows, deprecated patterns, security advisories).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Source Grounding <!-- SHARED:LANGUAGE_HEADER --> Standing rule — active every response. No invocation needed for routine use. ## Consent gates (G1–G4, declared) | # | what it gates | when it fires | Agent lane | Hook lane | |---|---|---|---|---| | G1 | model tier | before work starts | `ask_question`, 3 tiers, wait for pick | suppressed — auto-Light, no tier question | | G2 | how to proceed on an unfetchable source | source can't be fetched, user present | `ask_question` | `ask_question` | | G3 | entanglement hand-off | after the findings, cross-domain | `ask_question`, once | `ask_question`, once | | G4 | self error-report | skill misbehaves | offer, never auto-submit | offer, never auto-submit | Hook cells assume an interactive session (G2–G4 need a user to answer); non-interactive Hook fires D1 instead of G2, and offers nothing for G3/G4. ## What to verify (not memory) - **CRITICAL** (always fetch or flag — P2): 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 …

How to install
mdr add thecolliery/coalmine/source-grounding@sha256:4e13df4de60dd320The line at the top of this page pins the label git:20261002.e601852, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
