Writing Releases Agent Skill

Writing Medusa Release Notes

Generates GitHub release notes from commit/PR data in the established Medusa style.

Constraints

• Full Changelog link is mandatory — always the last line: Full Changelog: vPREV...vNEW
• No top-level Breaking Changes section — breaking changes are embedded inside their Highlight subsection with 🚧 Breaking change, never in a separate ## Breaking Changes heading
• Bullet format is strict — every entry in Features/Bugs/Chores/etc. must include author link and PR link (see reference/format.md)
• Highlights are not a summary of all PRs — only significant changes qualify; routine additions go in Features/Bugs bullets only (see reference/release-types.md)
• No emojis — the only permitted emoji is 🚧 on breaking change highlights; use none anywhere else
• Code block required for actionable steps — if a highlight requires the developer to install a package, run a command, or update config, include a fenced code block with the exact command(s)

Load Reference Files When Needed

> Load at least one reference file before writing.

| Task | Load |

|------|------|

| Formatting sections and bullets | reference/format.md |

| Deciding whether to write Highlights, and identifying breaking changes | reference/release-types.md |

| Writing the Highlights section | reference/highlights.md |

Quick Reference

Release type decision

| Commit set | Release type |

|-----------|-------------|

| Only routine fixes/chores, no user-facing impact | Minimal — no Highlights section |

| One important change is the main reason for the release | Single Highlight |

| Multiple significant features or fixes | Multi-Highlight |

| Any PR with a minor changeset in .changeset/ | Add 🚧 to that Highlight |

Section order (include only sections with entries)

## Highlights
## Features
## Bugs
## Documentation
## Chores
## Other Changes
## New Contributors

Common Mistakes

• [ ] Adding a title or # Heading at the top — release notes have no title, start directly with the first section
• [ ] Adding a ## Breaking Changes top-level section — embed inside the Highlight instead
• [ ] Putting a routine bug fix or small feature addition in Highlights
• [ ] Missing the Full Changelog link at the end
• [ ] Bullet missing author link or PR link
• [ ] Using PR title verbatim as a Highlight heading — write a descriptive outcome-focused title
• [ ] Treating every feat: commit as a Highlight candidate
• [ ] Using emojis anywhere except 🚧 on breaking change highlights
• [ ] Writing a Highlight that requires a developer action (install, run, config change) without a fenced code block
