Release notes

Produce release notes for a project by comparing a base ref against origin/main, classifying every change, and rendering the house format below. This skill is read-only: it writes markdown to the chat and creates, tags and publishes nothing. It hardcodes no repository, org, or taxonomy; it detects those, with optional overrides from a ## Releasing section in the project's CLAUDE.md / AGENTS.md.

0. Resolve the target repo

Decide which repository these notes cover; <dir> is that repo's directory and <slug> its owner/name on GitHub. Run every git command with git -C <dir> ... and every GitHub command with --repo <slug>.
