Changelog Generation

ZeroClaw Changelog Generation

You are generating a human-friendly CHANGELOG-next.md for a ZeroClaw release. The GitHub CLI (gh) is available and authenticated. The local repository is checked out and up to date.

Before You Start

This SKILL.md is the full, self-contained procedure. Follow the workflow below exactly on every run; do not rely on memory of a prior run.

Invocation

Default — last stable tag to HEAD:

generate changelog
write the changelog
CHANGELOG-next
prepare release notes

Explicit range:

changelog for v0.7.2
changelog v0.7.1..v0.7.2
what changed since v0.7.1
release notes v0.7.1 to v0.7.2

Workflow

Phase 1 — Establish the range

1. If the user provided a range, normalise to <from>..<to>: vX → vX..HEAD; vX..vY → as given; vX vY → vX..vY.
2. If no range was given, resolve the last stable tag automatically. Both -beta.N (older) and -beta-N (current) pre-release formats exist, so anchor on a plain version shape rather than excluding a -beta separator:

   git tag --sort=-creatordate | grep -E '^v[0-9]+\.[0-9]+\.[0-9]+$' | head -1
   

3. Verify both refs exist (git rev-parse --verify). If either is missing, stop and tell the user what was not found.
4. Report the resolved range to the user before continuing.

Phase 2 — Collect and categorise commits

Run all fetches in a single parallel batch — do not wait for one before starting the next:

# Full commit list with subjects (for categorisation)
git log <from>..<to> --pretty=format:"%H %h %s" --no-merges

# Full SHAs only (for contributor resolution)
git log <from>..<to> --pretty=format:"%H" --no-merges

Map each commit to a section by its conventional-commit prefix. Read and categorise prefix-less commits by content; never drop one silently.

Phase 3 — Resolve contributors

Use the GitHub GraphQL commit authors field (returns author + co-authors). Do not use git log --pretty=format:"%an" alone — it misses Co-Authored-By contributors.

gh api graphql -f query='
{ repository(owner:"zeroclaw-labs", name:"zeroclaw") {
    ref(qualifiedName:"refs/heads/master") { target { ... on Commit {
      history(first:100) {
        pageInfo { hasNextPage endCursor }
        nodes { oid authors(first:10) { nodes { user { login } email } } }
      } } } } } }'

Page by adding after:"<endCursor>" while hasNextPage is true. Cross-reference each oid against the Phase 2 SHA list to stay in range, collect unique logins, then exclude:

• logins ending in [bot], plus web-flow, dependabot, github-actions, blacksmith
• emails matching *noreply*
• AI model names as author names: Claude, Copilot, ChatGPT, Codex, Gemini, and anything matching ^(gpt|claude|gemini|copilot)-

Sort case-insensitively and prefix each with @.

Phase 4 — Write the changelog

Write these sections in order; omit any with no content:

1. Preamble (2–3 sentences — release theme, scale, reader context)
2. Highlights (4–6 user-visible bullet points)
3. What's New (grouped by area, human-readable sentences, PR references)
4. Bug Fixes (summary table: Area | Fix)
5. Breaking Changes (omit section entirely if none)
6. Contributors (@login handles, case-insensitive sort, one per line)
7. Footer (full diff reference)

Write to two locations:

• tmp/CHANGELOG-next.md — for in-session review before committing
• CHANGELOG-next.md in the repository root — the path the release workflows read

Phase 5 — Review and confirm

Present a summary to the user:

• Range covered
• Commit count by category
• Contributor count
• Any commits that had no conventional prefix (so the user can sanity-check categorisation)

Ask the user to review tmp/CHANGELOG-next.md before committing. Do not proceed to Phase 6 without explicit confirmation.

Phase 6 — Commit and push

Only after the user confirms the content:

git add CHANGELOG-next.md
git commit -m "chore(release): add CHANGELOG-next.md for vX.Y.Z"
git push upstream <branch>

Replace vX.Y.Z with the next release version — ask the user if unsure. Push to the open release PR branch on zeroclaw-labs/zeroclaw. Do not push to master directly.

Execution rules

1. This SKILL.md is self-contained and authoritative. Follow the phases above; do not look for a separate protocol file.
2. Always report the resolved range before doing any work. The user should confirm the range is correct before you collect commits.
3. Never drop commits silently. Every commit in the range must be accounted for in the output — either surfaced in a section or explicitly noted as omitted (e.g. trivial typo fix in docs).
4. Always use the GraphQL contributor path. git log --format="%an" alone is not acceptable — it produces an incomplete contributor list.
5. Always apply the full filter list. Bots, noreply addresses, and AI model names must be excluded from the contributor section.
6. Always write to tmp/CHANGELOG-next.md first. The user reviews before the file is committed to the repository root.
7. Always confirm before committing. Show the user the exact commit message and ask for an explicit yes. Do not infer consent from prior steps.
8. Never push to master directly. Always push to the open release PR branch.
9. Do not delete CHANGELOG-next.md manually. The file is intentionally left on master between releases and is overwritten at the start of the next release cycle. No cleanup is needed after a release ships.
