The page fits under the Tools docs and includes explicit warnings around interacting with a third‑party service. <h3>Confidence Score: 4/5</h3> - This PR is close to safe to merge once the documentation correctness issues are addressed. - Changes are documentation-only and include good third-party warnings, but two sections are currently misleading for copy/paste users: the Python integration snippet is not runnable as written, and the env var guidance incorrectly implies `AGENTS.md` can be used to `export` environment variables. Fixing these will reduce user confusion and support burden. - docs/tools/pinchwork.md <!-- greptile_other_comments_section --> **Context used:** - Context from `dashboard` - CLAUDE.md ([source](https://app.greptile.com/review/custom-context?memory=fd949e91-5c3a-4ab5-90a1-cbe184fd6ce8)) - Context from `dashboard` - AGENTS.md ([source](https://app.greptile.com/review/custom-context?memory=0d0c8278-ef8e-4d6c-ab21-f5527e322f13)) <!-- /greptile_comment -->
