typos — Source Code Spell Checker for CI

Operating Pattern

Fit check

Adoption loop

1. Run the tool on a disposable branch or sandbox project.
2. Capture before/after output so reviewers can see the exact effect.
3. Add the smallest CI or local check that prevents regressions.
4. Document owner, upgrade command, and rollback command in the repo.

Recommended use

Add it after formatting but before release notes. The fastest win is catching typos in README, prompt assets, CLI help text, and changelog entries.

Guardrails

Seed a project dictionary for product names and abbreviations; otherwise reviewers will waste time dismissing expected terms.

Rollout checklist

• Pin the package or release version before using it in CI.
• Keep credentials in environment variables or the platform secret store.
• Add one owner who is responsible for upgrades and breaking-change triage.
• Re-check the GitHub repo before writing docs that mention APIs or install paths.

FAQ

Q: Is this production-ready? A: The repo exists at https://github.com/crate-ci/typos and has 3,935 GitHub stars. Treat the first rollout as a controlled pilot until your team has tested install, rollback, and CI behavior.

Q: Why use it instead of a generic script? A: The value is repeatability: a named package, a documented command, a source repo, and a small verification path that can be reviewed by teammates.

Q: What should I measure first? A: Measure setup time against the 5 minutes target, count how many files or tasks it changes, and record whether the CI command catches the same issue locally.
