Autonomous release announcer for OpenAI's Codex. It watches the changelog, drafts a post, ships it to X — and commits its own memory back to the repo. Runs hourly, touches no human.

Every hour a GitHub Action wakes up and checks two sources:

• Codex app — the changelog at developers.openai.com/codex/changelog
• Codex CLI — public GitHub releases for openai/codex

Anything unseen goes to the local claude CLI, which writes a tight post — exactly 3 feature bullets, each starting with an emoji, the whole thing under 280 characters. It publishes to X, then writes the last-posted key back to .state/. (That's why the git log is a quiet stream of chore(state): update last posted keys.)

Several unseen entries at once? It posts them oldest → newest, and each source advances independently, so a same-day app + CLI drop don't block each other.

bun install
bun run index.ts

Post copy comes from Claude, and only Claude. If the output isn't 3–5 emoji-led lines under the character budget, it retries up to 3 times and then hard-fails rather than tweet something malformed. Better silent than sloppy.

.github/workflows/hourly.yml — 0 * * * * plus a manual trigger. One run generates, publishes, and commits state.
