Release Prep Skill

This skill automates release preparation for MassGen, generating CHANGELOG entries, announcement text, and validating documentation.

When to Use

Run this skill when preparing a new release:

• After merging the release PR to main
• Before creating the git tag

Usage

/release-prep v0.1.34

What This Skill Does

1. Gather Changes

Read commits and PRs since the last tag:

# Get last tag
git describe --tags --abbrev=0

# Get commits since last tag
git log v0.1.33..HEAD --oneline

# Get merged PRs (if using GitHub)
gh pr list --base main --state merged --search "merged:>2024-01-01"

2. Archive Previous Announcement

If `docs/announcements/current-release.md` exists:

# Extract version from current-release.md
VERSION=$(grep -m1 "^# MassGen v" docs/announcements/current-release.md | sed 's/# MassGen v\([^ ]*\).*/\1/')

# Archive it
mv docs/announcements/current-release.md docs/announcements/archive/v${VERSION}.md

3. Generate CHANGELOG Entry

**Update the Recent Releases section** at the top of `CHANGELOG.md`:

• Add the new release summary at the top
• Keep only the **3 newest releases** in this section
• Remove older entries (they remain in the detailed changelog below)

Create a structured entry following Keep a Changelog format:
