Checks that what a repository's documents say actually exists - cited paths, links and anchors, parity between README.md and README.pt-BR.md, and versions and the plugin list against the manifests. Read-only, no network, exit code 0/1/2. Use when the user asks to check, audit or validate the documentation, for example "os docs estão certos?", "tem link quebrado?", "o README cita arquivo que não existe?", "o README em português está igual ao em inglês?", "doc-truth", "check the docs…
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
# doc-truth (do the documents tell the truth?) Reads every `.md` file tracked by git and checks what it claims against the repository: the cited path exists, the link and the anchor lead somewhere, `README.md` and `README.pt-BR.md` have the same structure, the version written next to a plugin's name is the one in the manifest. It is **read-only**: it never changes the repository, never runs a command that a document cites, and does not use the network. It needs `python3` (stdlib) and `git`. It does not check external links (`https://...`) and does not check whether a description is correct, only whether what it points to exists. Reply to the user in the user's language. The tool prints its output in English by default; run it with `--lang pt-BR` when the user writes in Portuguese (accent-free Portuguese; `CAPYBARA_LANG` may set the default for the whole shell). When you present the findings, explain them in the user's language and keep the category names, values, paths and fingerprints exactly as printed: a finding's value and fingerprint are the same in both languages, only its message changes. ## When to use …

How to install
mdr add dvwinck/capybara-toolbox/doc-truth@sha256:b220ac880f118bfdThe line at the top of this page pins the label git:20261023.fe5fbd7, 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.
