academic-verify skillA
academic-verify is agent-read markdown (skill) from garrytan/gbrain: Verify a research claim or academic citation by tracing it through publication → methodology → raw data → independent replication. Routes through perplexity-research for the actual web lookup, then formats results as a citation-checked brain page. Use when a book/article/conversation cites a study and you want to confirm the claim is real, replicated, and accurately characterized..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# academic-verify — Trace Claims to Source Data > **Convention:** see [conventions/quality.md](../conventions/quality.md) for > citation rules; every verdict cites the source data, not just the > author's claim about the source data. > > **Convention:** see [conventions/brain-first.md](../conventions/brain-first.md) > for the lookup chain. This skill enforces brain-first by checking > existing brain pages before issuing a fresh web search. ## What this is A claim-verification flow for academic / research statements. When a book, article, or speaker cites a study or quotes a number, this skill traces the claim through: ``` claim → publication → methodology section → raw data source → independent verification ``` At each step, it answers: - **Where does this number come from?** (Self-generated? Survey? Government data?) - **What's the baseline?** (Reduction from what? Over what time period?) - **Is the raw data available?** (Public? Proprietary? "Available on request"?) - **Has anyone independently verified it?** (Replication study? Government audit?) - **Are there confounding factors?** (Other interventions, policy changes, COVID, sampling bias?) …

How to install
mdr add garrytan/gbrain/academic-verify@v0.1.0mdr add garrytan/gbrain/academic-verify@sha256:1c19e27e75249d86Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
