Excerpt

Codex Update Compat

Use this workflow to safely upgrade Codex and close update-induced regressions.

Workflow

Inspect update scope before changing code. Run:

git log --oneline -n 5
git show --name-only --oneline -n 1

Focus first on package.json, package-lock.json, and generated src/app-server/** changes.

Run typecheck and tests immediately. Run:

npm run typecheck
npm test

Treat type errors as the migration guide for required protocol changes.

This is the opening of the README. Read the full README on GitHub.
