Answers questions about another repository or a dependency by cloning it under a temporary directory and reading its source, docs, and history, and reports findings linked to GitHub at that revision. Use when the task is to learn how a dependency or upstream project works, why something changed in it, or how it compares with local code.

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

# Researching external repositories

Answer the brief's question from the repository's own source, not from memory. Clone what you need, read it, and report findings the caller can verify from the links and from the local clones you leave behind.

Where to look depends on the question. How it works: the source. How to use it: the docs for that version, and the source when the docs are unclear. Why or when it changed: `git log` and `git blame`, then the issues and pull requests the commits mention. A copy inside the workspace, such as `node_modules` or a vendored directory, tells you the version; read the code in the clone.

## Cloning

Run git with `shell_command`, always with `workdir` set. Clone every repository you study into its own directory under `/tmp/amp-librarian/` named `<owner>__<repo>` (on Windows, under `%TEMP%\amp-librarian\`). Reuse the directory when it already exists (`test -d "$dir/.git"`). For `owner/repo` or a github.com URL, clone `https://github.com/<owner>/<repo>.git`; for another host, clone the URL as given. Private repositories the user can reach clone with the environment's git credentials; if a clone is denied, report that instead of guessing at the…

How to install

The exact contents, by fingerprint
mdr add ampcode/official-plugins/researching-external-repositories@sha256:17cf71c07f8ee3cb

The line at the top of this page pins the label git:20261023.acb8c9d, 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.
