Release Changelog Skill

Generate the user-facing changelog for the stable OnePersonCapital release.

Output:

• releases/v{version}.md

Important rule:

• even if there are canary releases such as 1.2.3-canary.0, the changelog file stays releases/v1.2.3.md

Step 0 — Idempotency Check

Before generating anything, check whether the file already exists:

ls releases/v{version}.md 2>/dev/null

If it exists:

1. read it first
2. present it to the reviewer
3. ask whether to keep it, regenerate it, or update specific sections
4. never overwrite it silently

Step 1 — Determine the Stable Range

Find the last stable tag:

git tag --list 'v*' --sort=-version:refname | head -1
git log v{last}..HEAD --oneline --no-merges

The planned stable version comes from one of:

• an explicit maintainer request
• the chosen bump type applied to the last stable tag
• the release plan already agreed in doc/RELEASING.md

Do not derive the changelog version from a canary tag or prerelease suffix.

Step 2 — Gather the Raw Inputs

Collect release data from:

1. git commits since the last stable tag
2. .changeset/*.md files
3. merged PRs via gh when available

Useful commands:

git log v{last}..HEAD --oneline --no-merges
git log v{last}..HEAD --format="%H %s" --no-merges
ls .changeset/*.md | grep -v README.md
gh pr list --state merged --search "merged:>={last-tag-date}" --json number,title,body,labels

Step 3 — Detect Breaking Changes

Look for:

• destructive migrations
• removed or changed API fields/endpoints
• renamed or removed config keys
• major changesets
• BREAKING: or BREAKING CHANGE: commit signals

Key commands:

git diff --name-only v{last}..HEAD -- packages/db/src/migrations/
git diff v{last}..HEAD -- packages/db/src/schema/
git diff v{last}..HEAD -- server/src/routes/ server/src/api/
git log v{last}..HEAD --format="%s" | rg -n 'BREAKING CHANGE|BREAKING:|^[a-z]+!:' || true

If the requested bump is lower than the minimum required bump, flag that before the release proceeds.
