From b6c5aab343b04b483bd13b9485e4c4a6942eb59d Mon Sep 17 00:00:00 2001 From: Henry Schreiner Date: Tue, 18 Aug 2026 00:31:10 -0400 Subject: [PATCH 1/5] chore: add prepare-release and publish-release agent skills Split the release process from docs/release.rst into two agent skills: a changelog/version-bump PR, and the manual publication steps after that PR merges.

This is the default +release commit. A later commit may be selected only when its extra changes are +intentional, it descends from the preparation commit on the same release base, +and equivalent CI passed. Review every extra commit for version, metadata, and +changelog implications; either explicitly record that no release-note update +is needed or add one and select the resulting tested commit. Never release an +unreviewed branch tip. Record the introducing PR/review and exact CI-tested +SHA; the tested and release commits must be identical or have identical source +trees. + +Persist a release checkpoint outside the worktree so a retry cannot silently +fall back to the preparation merge commit. It should contain the version, tag, +preparation PR/base/merge SHA, selected and CI-tested commits/trees, review and +CI evidence, consumed changelog PRs, tag-object and peeled SHAs, and resulting +branch, release, and workflow IDs.

Before a remote tag exists, correct a slipped date only + through a follow-up PR against the same release base and retest the resulting + release tree.

Stop if the histories diverge. + +Tag and publish +~~~~~~~~~~~~~~~ + +#. Create an annotated ```` on the exact release commit and push only that + tag: + + .. code-block:: bash + + git tag -a -m ' release' + git push upstream refs/tags/ + + Inspect local and remote tag state independently. If neither exists, create + the local tag. A valid local-only tag can be pushed after confirmation; a + remote-only tag must be fetched into a non-overwriting temporary ref and + validated before the remote step is considered complete. Materialize the + identical local tag without overwriting anything if later steps need its + canonical name. When both exist, + their tag-object IDs must match. In every case, require an annotated tag that + peels to the recorded release commit; a lightweight tag is not equivalent + and must not be silently replaced. Recheck the source version and changelog + against the tag before pushing. + A deliberately superseded local-only tag may be replaced only after explicit + confirmation; never move or replace a remote tag. + If a checkpointed, unpushed tag object was lost with its checkout, confirm + that no remote tag exists before regenerating it and updating the checkpoint. + +#. Update ``stable`` only for a final release that should become the project's + designated current stable line. Inspect the line currently represented by + ``upstream/stable``. Never update it for a prerelease or move it backward to + an older maintenance line.
