Package Release

Package Release Skill

Overview

Orchestrates Backend Engineer → Testing Specialist → DevOps Engineer for safe, validated releases of the active root ttadev package.

[!WARNING] Current release automation targets the root ttadev package and the packages/ttadev/v{semver} tag format.

Older tta-dev-primitives, platform/primitives, and token-based release steps belonged to an earlier package layout. Use the workflow-based release.yml + publish.yml flow below instead.

Prerequisites

Before starting:

• ✅ Clean git working directory
• ✅ All local quality gates passing
• ✅ On main or a release branch
• ✅ GitHub access to push tags and inspect workflow runs
• ✅ PyPI trusted publisher configured for .github/workflows/publish.yml

Verify:

git status
.github/copilot-hooks/post-generation.sh
git branch --show-current
gh workflow view release.yml
gh workflow view publish.yml

Stage 1: Prepare Release (Backend Engineer)

Goal: bump the root package version, update release notes, and prepare the repo.

Step 1.1: Determine the version bump

LAST_TAG=$(git tag --list 'packages/ttadev/v*' --sort=-version:refname | head -1)

if [ -n "$LAST_TAG" ]; then
  git log "$LAST_TAG"..HEAD --oneline
else
  git log --oneline
fi

Choose:

• Patch for fixes only
• Minor for backward-compatible features
• Major for breaking changes

Step 1.2: Update the root version

OLD_VERSION=$(grep '^version =' pyproject.toml | cut -d'"' -f2)
NEW_VERSION="0.1.1"

sed -i "s/^version = \"$OLD_VERSION\"/version = \"$NEW_VERSION\"/" pyproject.toml
grep '^version =' pyproject.toml

Step 1.3: Update release notes

Add the new section to CHANGELOG.md and review any pinned version references in active docs:

grep -n "0\\.1\\.0\\|0\\.1\\.1" README.md GETTING_STARTED.md PUBLISHING.md || true

Step 1.4: Commit release preparation

git add pyproject.toml CHANGELOG.md README.md GETTING_STARTED.md PUBLISHING.md
git commit -m "chore(release): prepare ttadev v$NEW_VERSION"
git push origin main

Handoff: @testing-specialist Release prep is pushed; validate the gates.

Stage 2: Quality Validation (Testing Specialist)

Goal: confirm the repo is green before any tag is pushed.

Step 2.1: Run the standard gate

.github/copilot-hooks/post-generation.sh

Step 2.2: Optional deeper validation

uv run pytest -v --tb=short -m "not integration and not slow and not external"
uv build --out-dir dist
ls -lh dist/
rm -rf dist

Step 2.3: Check CI status

COMMIT_SHA=$(git rev-parse HEAD)
gh run watch "$(gh run list --commit "$COMMIT_SHA" --json databaseId -q '.[0].databaseId')"
gh run list --commit "$COMMIT_SHA" --json conclusion -q '.[0].conclusion'

Pass criteria

• ✅ Standard repo gate passes
• ✅ CI checks are green
• ✅ Root package builds successfully
• ✅ No release-blocking issues remain

Handoff: @devops-engineer Quality gates passed; proceed with release workflows.

Stage 3: Deploy and Verify (DevOps Engineer)

Goal: create the release tag, let GitHub create the release, and optionally publish to PyPI.

Step 3.1: Create and push the release tag

git tag "packages/ttadev/v$NEW_VERSION"
git push origin "packages/ttadev/v$NEW_VERSION"
git tag --list "packages/ttadev/v$NEW_VERSION"

Step 3.2: Verify the GitHub Release workflow

release.yml triggers automatically from the pushed tag.

gh run watch "$(gh run list --workflow=release.yml --json databaseId -q '.[0].databaseId')"
gh release view "packages/ttadev/v$NEW_VERSION"

Step 3.3: Trigger PyPI publish

publish.yml is manual and uses GitHub OIDC trusted publishing.

gh workflow run publish.yml -f tag="packages/ttadev/v$NEW_VERSION"
gh run watch "$(gh run list --workflow=publish.yml --json databaseId -q '.[0].databaseId')"
uv pip index versions ttadev | head -5

Step 3.4: Post-release verification

docker run --rm -t python:3.11 bash -lc "
  pip install ttadev==$NEW_VERSION &&
  python -c 'import ttadev; print(ttadev.__file__)'
"

Success Criteria

Release is successful when:

• ✅ pyproject.toml version is updated
• ✅ CHANGELOG.md reflects the release
• ✅ Local and CI quality gates are green
• ✅ Git tag exists in the form packages/ttadev/vX.Y.Z
• ✅ release.yml created the GitHub Release
• ✅ publish.yml published ttadev to PyPI
• ✅ Users can install the released version

Rollback Procedure

If a release goes bad:

1. Yank the PyPI release

Use the PyPI web UI for the ttadev project to yank the bad release if necessary.

2. Delete the release tag

git tag -d "packages/ttadev/v$NEW_VERSION"
git push origin :"refs/tags/packages/ttadev/v$NEW_VERSION"

3. Prepare a hotfix

git checkout -b hotfix/ttadev-v$NEW_VERSION-fix
# apply fix
git commit -am "fix: critical issue in ttadev v$NEW_VERSION"

Common Issues

Issue: Standard gate fails

Solution: fix the failing lint, type, or test checks before tagging.

Issue: publish.yml fails

Solution: verify the pypi environment and trusted publisher configuration, then rerun the workflow.

Issue: Package not installable immediately

Solution: wait a few minutes for PyPI indexing/CDN propagation, then retry verification.
