Step 0 — Determine target version

Provided version: $ARGUMENTS

If a version was provided (above is non-empty)

Validate it as a PEP 440 string (e.g. 1.2.3, 1.2.3a1, 1.2.3rc1, 1.2.3.post1). Note: PEP 440 versions must not start with v — that prefix belongs on the git tag, not the version string. Stop and ask the user to correct it if invalid. Store it as VERSION for all subsequent steps.

If no version was provided (above is empty)

Analyze the commits listed in Step 1 to recommend the correct next version. The last tag shown in Step 1 uses a v prefix (e.g. v1.14.3); strip it when computing the next version so the result is a bare PEP 440 string (e.g. 1.14.4, not v1.14.4).

Apply these semver rules:

• Major bump (X+1.0.0) — any commit that breaks a public API or documented behaviour
• Minor bump (X.Y+1.0) — any new public feature or API addition, no breaking changes
• Patch bump (X.Y.Z+1) — bug fixes, security patches, chores, docs, or refactoring only

Show your reasoning and proposed version to the user, then ask them to confirm or override it. Store the confirmed version as VERSION for all subsequent steps.

Step 1 — Review commits since the last release

Fetch tags:

!git fetch --tags -q || echo "Warning: failed to fetch tags — check network/auth and consider retrying."

Last tag: !git describe --tags --abbrev=0 2>/dev/null || echo "(none)"

Today's date: !date +%Y-%m-%d

Now list the commits since the last release by running one of these commands:

• If "Last tag" above is (none): run git log --oneline
• Otherwise: run git log <LAST_TAG>..HEAD --oneline (substituting the actual tag)

You must run this command and review the output before proceeding to Step 0 or Step 2.

Step 2 — Draft changelog entry

Read docs/changelog.rst to understand the current format, then draft a new entry for VERSION using this RST format:

VERSION (YYYY-MM-DD)
--------------------

- [category] Description (#PR)

Important: The - underline must be at least as long as the title line (RST requirement). Count the exact characters in VERSION (YYYY-MM-DD) and use that many dashes.

Use these categories (pick the most specific one per bullet):

• api — public API additions or changes
• psd — low-level PSD parsing/writing
• fix — bug fixes
• refactor — internal restructuring, no behaviour change
• docs — documentation only
• ci — CI/CD, GitHub Actions
• chore — dependency bumps, tooling, housekeeping
• security — security fixes

Group related changes. Omit purely internal churn that users won't care about. Reference PR numbers where available.

Show the draft to the user and ask for approval or edits before continuing.

Step 3 — Update docs/changelog.rst

Prepend the approved changelog entry directly after the Changelog header block and the following blank line, leaving a blank line between the header and the new entry.

Step 4 — Create release branch and commit

git checkout -b release/vVERSION

Then update src/psd_tools/version.py using the Edit tool — replace the existing __version__ line with:

__version__ = "VERSION"

VERSION is the bare PEP 440 string without the v prefix (e.g. 1.15.0, not v1.15.0).

Then stage both changed files and commit:

git add docs/changelog.rst src/psd_tools/version.py
git commit -m "docs: release vVERSION"
git push -u origin release/vVERSION

Replace VERSION with the actual version string (e.g. 1.15.0).

Step 5 — Open a pull request

Run gh pr create with --title "Release vVERSION" and a --body containing:

• A ## Release vVERSION heading
• A ### Changelog section with the approved entry from Step 2 pasted in
• A ### Release checklist section with these items:
  • [ ] Changelog entry reviewed and accurate
  • [ ] Version follows PEP 440
• A closing note: "After this PR is merged, the auto-tag workflow will tag the merge commit as vVERSION and the release workflow will build wheels and publish to PyPI automatically."

Replace VERSION with the actual version string throughout.

Step 6 — Done

Print the PR URL. Remind the user:

After the PR is approved and merged, the auto-tag GitHub Actions workflow tags the merge commit as vVERSION automatically. That tag push triggers the release workflow to build wheels for all platforms and publish to PyPI. No manual tagging or publishing is needed.

Replace VERSION with the actual version string.
