Verify a falsifiable claim about the current state of the codebase,.
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
# /rdf:r-verify-claim — Evidence Verification Skill Verify a falsifiable claim about the current state of the codebase, a commit, or a file. Produces a structured triage report with probe commands, results, and a PASS/FAIL/UNVERIFIABLE verdict. Operates as a skill the model invokes on itself to produce evidence, or a slash command the user types to sanity-check an asserted claim. ## Invocation ``` /rdf:r-verify-claim "free-text claim" /rdf:r-verify-claim --commit <sha> "claim" /rdf:r-verify-claim --grep <pattern> <path> /rdf:r-verify-claim --from-finding <sentinel-N.md> ``` **Argument detection:** - `--commit <sha>` anchors the claim to a specific commit - `--grep <pattern> <path>` is a shortcut for pattern-absent/present classes - `--from-finding <file>` extracts claim text from a sentinel finding file - Plain string → free-text claim, classifier decides the probe class ## Claim Classifier The classifier reads the claim text and assigns one of 5 closed-set classes. Each class has a pre-written probe template. | Class | Trigger phrases | Probe template | |-------|----------------|----------------| …

How to install
mdr add rfxn/rdf/r-verify-claim@sha256:2c88a97667ce24bdThe line at the top of this page pins the label git:20260902.42a192d, 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.
