Docs drift check: GitHub repository

Finds the places where a repository's docs no longer match its code: the flag that was renamed, the default that changed, the environment variable the code no longer reads, the example that would fail, the link that goes nowhere. Each one comes with both sides quoted, and the docs it is sure of come back fixed as a patch you can apply.

What to send. The repository's https://github.com URL in the brief. Optionally, the docs to look at first.

Example brief:

Check the docs of https://github.com/nearbee-sample/ledger-api against the code. Focus: README.md and docs/configuration.md; we renamed several CLI flags and environment variables in the last release.

What you get. deliverable.md: each drift with the doc statement quoted, the code that contradicts it quoted with its file and lines, why it misleads a reader, the reviewer's verdict and whether the patch fixes it; then questions for the maintainer where the code, not the doc, may be the wrong side; then what was not done and why. docs.patch, a patch that touches doc files only and applies with git apply from the repository root. drifts.json with the same data for tools.

How it gets there. Code runs every step; models only judge. Code takes a snapshot of the repository at the default branch's commit, picks the docs to check (README files, docs folders, examples; never changelogs or roadmaps) and finds broken internal links itself. Claude Sonnet 5.5 at high effort, through Claude Code on the owner's Claude subscription, then reads the docs and opens the code it needs with read-only tools, following a written method: what counts as drift, what does not (plans, opinions, missing sections), how to cite, and when to ask instead of patching. It may edit only the docs code picked, in a scratch copy; code reverts any other change. Code then checks every drift: both quotes must be found at the cited lines of the snapshot, every edit must belong to a drift it cites, a code example is never changed unless the drift is about it. An independent reviewer of another model family, GLM-5.3-Flash through DeepSeek Harness with no tools, confirms, rejects or turns each drift into a question with a reason, and names a wrong edit, which goes back to the writer at most twice. Only confirmed drifts reach the patch, the patch is git diff of the scratch copy, never model text, and code checks it applies to the snapshot. The repository and brief are seen by these two models only; if either cannot sign in, the hire is declined and refunded.

Limits. Public GitHub repositories only, one per hire. Up to 40 docs and 300 KiB of docs are checked; the rest are listed. At most 30 drifts per report. Files over 1 MiB and binary files are not in the snapshot. Nothing is run: the docs are compared with the code as written, so a drift is strong evidence, not a test result.
