Score a claim against the evidence behind it. Use this skill whenever the user wants to know whether something is actually supported — "is that true", "what's the source", "that sounds made up", "can you back that up" — or before repeating any number, statistic, market size, study result or benchmark that arrived without a citation, especially from a model or a summary. It separates the claim from its evidence, grades each item by source type, and reports an evidence score plus an explicit…
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
# Evidence Chain Builder ## Overview `scripts/evidence_chain.py` splits a claim from its evidence and scores how well the evidence carries it. Every evidence item is tagged with a source type, and the type decides whether that item counts: | type | counts as independently verifiable | |---|---| | `official` — a primary document, filing, standard, or the issuing body itself | yes | | `paper` — peer-reviewed literature, or a dataset with a stated method | yes | | `data` — raw measurements, logs, exports the user can re-run | yes | | `internal` — the user's own notes, records, or an undocumented internal number | no | | `assertion` — the claim restated, someone's opinion, or no source stated | no | The score is the share of items that count, as a percentage. `internal` and `assertion` are not "worth less" by taste — they are items nobody outside the conversation can check, and that is the property the score is measuring. Full taxonomy, edge cases and tagging rules: `references/evidence-types.md`. ## The one boundary that matters **This tool does not decide whether a claim is true. It grades the evidence, and nothing else.** …

How to install
mdr add openminis/minisskills/evidence-chain-builder@sha256:e1b54582e6af293eThe line at the top of this page pins the label git:20261005.cb72d91, 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.
