Codex Changelog

Goal

Resolve the installed Codex CLI and Codex App versions and return two sections:

• Codex CLI: the matching GitHub release changelog from openai/codex/releases
• Codex App: the matching desktop-app changelog from https://developers.openai.com/codex/changelog

Trigger rules

• Use when the user asks for Codex version, release notes, or changelog details for the CLI, app, or both.
• Prefer this skill for installed-version changelog lookups instead of ad-hoc browsing.
• Always fetch Codex CLI notes from GitHub Releases, even though the OpenAI changelog page also lists CLI entries.
• If no installed CLI or app version can be resolved, report the failure and provide the nearest fallback tags or app versions.
