Docs Drift Check is currently designed and tested for:

Codex repo-local skill usage
Codex local plugin usage through repo or personal marketplaces
Git repositories with branch-based diffs
shell environments that can run the bundled Bash helper

Validated repo types in this repository

small Next.js repos
larger frontend repos with deployment config
research or Python repos with setup-heavy READMEs

Current assumptions

git is available
the repository has at least one commit
a valid base ref such as main or master exists locally

Known limitations

The helper is heuristic-based and not semantic-proof.
It is strongest on public-surface changes such as commands, env vars, routes, config keys, and renames.
It is weaker on subtle behavioral changes that do not leave recognizable diff markers.
