Write Minor/Major Release Changelog

Assembles and writes a polished changelog entry for a Storybook minor or major (X.Y.0) release into CHANGELOG.md.

Rules — read before doing anything

• The two helper scripts are at .agents/skills/minor-release/get-minor-changelog-summary.ts and .agents/skills/minor-release/write-minor-changelog-section.ts. Do not search for them anywhere else in the repo. Do not look in scripts/, package.json, AGENTS.md, or elsewhere. Do not read the script source files. Just run them.
• Do not read CHANGELOG.md or CHANGELOG.prerelease.md before running the scripts. The scripts handle version detection and entry collection automatically.
• Do not read CHANGELOG.md for style guidance. The style examples in Step 3 of this skill are the authoritative reference. Do not grep or read the changelog to infer format.
• Run all commands from the repository root.

Step 1: Collect the changelog entries

Run the helper script to see all unique changelog entries from the prereleases, with patch-backported changes filtered out:

node .agents/skills/minor-release/get-minor-changelog-summary.ts [version]
