description	Ship a release branch by publishing a GitHub release using the gh CLI. Parses version from self.versions.toml and gets release notes from docs/CHANGELOG.md.

Ship Release Branch Skill

Overview

This skill guides the agent in shipping a release branch by creating and publishing a GitHub release pointing to the tip of the release branch. It ensures consistency by:

1. Resolving the release version directly from self.versions.toml on the target release branch (never assuming the branch name matches the version name, as hotfixes are appended to existing release branches).
2. Extracting release notes from the corresponding section in docs/CHANGELOG.md.
3. Publishing the GitHub release using the gh CLI with matching tag name and release name (format: v<VERSION>).

Dependencies

• release-branch-skill: Typically run after a release branch is cut and hardened.

Prerequisites

• Merge PRs via GitHub: Ensure the version bump PR (and any hardening PRs) are merged via the GitHub UI or gh pr merge. NEVER use local merge commits on the release branch.
• Pull Latest: Once PRs are merged on GitHub, checkout the release branch locally and pull the latest changes from origin to ensure the local branch is up-to-date before starting the release process.
• Verify Version: The version in self.versions.toml must NOT end with -SNAPSHOT. If it does, the release process must be aborted until the version is properly bumped.

Quick Start

To perform a dry-run and verify release notes/version before shipping:

./scripts/ship-release.py --dry-run --output /tmp/release-dry-run.json

To ship the current release branch:

./scripts/ship-release.py --output /tmp/release-result.json

Utility Scripts

The skill uses the ./scripts/ship-release.py script.

Arguments

• --branch <branch>: Target branch/ref to point the release to (defaults to current branch).
• --dry-run: Prints release details and the gh command without executing them.
• --output <file_path>: (Required) Path to write a JSON report of the release results.

Example JSON output (/tmp/release-result.json):

{
  "success": true,
  "dry_run": false,
  "tag": "v1.1.0",
  "title": "v1.1.0",
  "branch": "release/v1.1.0",
  "url": "https://github.com/episode6/mockspresso2/releases/tag/v2.0.2",
  "notes": "- CI: Use gradle/actions/setup-gradle@v6...\n- Upgraded Kotlin to 2.3.21..."
}

Common Mistakes

1. Shipping a Snapshot: Trying to ship when the version in self.versions.toml still contains -SNAPSHOT. The script will detect this and fail.
2. Missing Changelog Section: Forgetting to update docs/CHANGELOG.md with the release version and date. The script will fail if the section matching v<VERSION> cannot be found.
3. Mismatched release notes: Assuming the release notes can be typed manually. Always extract them directly from docs/CHANGELOG.md using the script to avoid discrepancies.
4. Stale Local Branch: Forgetting to pull the latest changes from origin before shipping, which can lead to releasing an outdated version of the code.
