+#!/usr/bin/env python3
+"""
+Automate the release procedure documented in `../README.md → Releasing codex`.
+
+Run this script from the repository *root*:
+
+```bash
+python release_codex.py
+```
+
+It performs the same steps that the README lists manually:
+
+1. Create and switch to a `bump-version-<timestamp>` branch.
+2. Bump the timestamp-based version in `codex-cli/package.json` **and**
+   `codex-cli/src/utils/session.ts`.
+3. Commit with a DCO sign-off.
+4. Copy the top-level `README.md` into `codex-cli/` (npm consumers see it).
+5. Run `pnpm release` (copies README again, builds, publishes to npm).
+6. Push the branch so you can open a PR that merges the version bump.
+
+The current directory can live anywhere; all paths are resolved relative to
+this file so moving it elsewhere (e.g. into `scripts/`) still works.
