Release Workflow

Steps

1. Sync the release branch, then run tests and lints: The release branch is long-lived and may sit behind main (or carry leftover state) when a cycle starts. Basing the changelog on a stale branch silently drops any commit merged to main after the branch was last realigned — git log <last-version>..HEAD won't show it. Bring it current first: git fetch origin && git merge origin/main (resolve any conflicts; if release has no commits of its own, git reset --hard origin/main instead). Then wt test and pre-commit run --all-files.
2. Check current version: Read version in generator/pyproject.toml
3. Review commits: git log <last-version>..origin/main --oneline to understand scope — against origin/main (not HEAD), so the range is the full set of commits this release ships even if step 1 was skipped
4. Confirm version with user: Present changes summary and proposed version
5. Bump version: Edit version in generator/pyproject.toml, then cd generator && uv lock
6. Update CHANGELOG: Add a ## X.Y.Z section at the top of CHANGELOG.md (see "CHANGELOG" below). The release workflow publishes this section verbatim as the GitHub Release notes and fails the GitHub Release job if the section is missing (PyPI publish has already happened by then; recovery is a manual gh release create), so it must land in the release commit — before the tag.
7. Commit on the current branch: chore: release X.Y.Z (version bump, lockfile, and CHANGELOG). Don't create a new branch — this worktree is already on the release branch, and the PR opens from it to main.
8. Merge to main: Push, create PR via gh pr create, wait for CI, merge with gh pr merge --squash
9. Tag and push: git tag X.Y.Z && git push origin X.Y.Z — triggers .github/workflows/pypi-release.yaml, which publishes to PyPI and creates a GitHub Release from the version's CHANGELOG section.
10. Wait for the release workflow: Poll until uvx tend@X.Y.Z --help succeeds and the release appears (gh release view X.Y.Z).
11. Regenerate tend's own workflows: Stay on the release branch (don't create a new one — same as step 7). The squash-merge deleted origin/release, so git fetch && git reset --hard origin/main to realign with the squashed history. Then uvx tend@latest init, commit, push, and open a PR titled chore: regenerate workflows with tend X.Y.Z. Until this merges, tend's deployed workflows lag the just-released generator, so critical fixes (e.g. loop-prevention filters) remain unreachable on tend itself.

CHANGELOG

CHANGELOG.md holds one ## X.Y.Z section per release, newest first. The header must be exactly ## X.Y.Z — the release workflow matches it literally to extract the notes.

Draft the section from the commits since the last release (git log <last-version>..origin/main --oneline):

• Group by section, in order, omitting empty ones: Improved, Fixed, Documentation, Internal. Internal is for selected notable internals, not everything.
• Combine related PRs into one bullet; cite them all in a trailing ([#a](url), [#b](url)) list. Use full https://github.com/max-sixty/tend/pull/N URLs so links resolve from the GitHub Release page.
• Be brief: 1–3 sentences per bullet; Internal bullets terser.
• No editorial framing: describe what changed, not what was wrong with the old approach.
• Verify against the diff, not the commit subject — subjects often undersell or misdescribe. git show <sha> anything user-facing before trusting its bullet.

Version scheme

Tags are bare versions (0.0.9), not prefixed (v0.0.9).

Generated workflows pin the action to the generator's own version (max-sixty/tend@X.Y.Z); there is no floating v1. Each X.Y.Z tag is the immutable ref consumers run, enforced by a tag ruleset on max-sixty/tend (update/deletion restricted). Never force-move or delete a published tag. Step 9 (tag) must precede step 11 (regenerate via uvx tend@latest) so the pinned ref resolves to an existing tag.

Commit message pattern

chore: release X.Y.Z

Bumps generator version to X.Y.Z and syncs lockfile.
