git-flow-release

name	git-flow-release
description	Create a release for this repository by tagging main with calendar versioning (optionally using git-flow if configured); use when the user asks to create a release or bump version.

Release

Communication

• Communicate with the developer in Japanese.
• Write commit messages and tag messages in English.

Prerequisites

Before starting the release process, verify:

1. All changes are committed (git status should show a clean working tree).
2. You are on the target branch (main unless the user specifies otherwise).

This repository does not have mandatory lint/test commands; do not run Node/bun/turbo checks here.

Version Format

Use calendar-based versioning with v prefix for git tags:

• Git tag: vYYYY.MM.DD.N (e.g., v2026.02.04.1)

Components:

• YYYY: 4-digit year (e.g., 2026)
• MM: 2-digit month (e.g., 02)
• DD: 2-digit day (e.g., 04)
• N: Daily release number starting from 1, incrementing for each subsequent release on the same day

Version Determination

1. Determine today's date in YYYY.MM.DD:

   today=$(date +%Y.%m.%d)
   

2. Check existing tags for today:

   git tag --list "v${today}.*"
   

3. Choose the next N:

   • If no tags exist for today, use N=1 → vYYYY.MM.DD.1
   • If tags exist for today (e.g., vYYYY.MM.DD.1), increment N (e.g., vYYYY.MM.DD.2)

Release Workflow (tag-based)

Execute the following steps in order:

1. Determine version

   • Decide YYYY.MM.DD.N and prepare short release notes (bullet list)

2. Commit changes (if needed)

   git add -A
   git commit -m "chore: prepare release vYYYY.MM.DD.N"
   

3. Create annotated tag

   git tag -a vYYYY.MM.DD.N -m "Release vYYYY.MM.DD.N"
   

4. Push main with tags

   git push origin main --tags
   

5. (Optional) Create a GitHub Release

   If gh is available and the user requests it:

   gh release create vYYYY.MM.DD.N --generate-notes
   

Git-flow (optional)

Only use this section if git-flow is configured for the repository (a develop branch exists and git flow init has been run).

1. Start release

   git flow release start YYYY.MM.DD.N
   

2. Finish release (macOS/BSD safe path)

   Always finish without tagging and add the tag manually (avoids getopt errors with -m).

   git flow release finish -n YYYY.MM.DD.N
   git switch main
   git tag -a vYYYY.MM.DD.N -m "Release vYYYY.MM.DD.N"
   

3. Push branches and tags

   git push origin develop
   git push origin main --tags
   

Post-release Report

After completing all steps, report:

• The released version number (e.g., 2026.02.04.1)
• The tag name created (e.g., v2026.02.04.1)
• Confirmation that the tag was pushed
• (If created) Confirmation that the GitHub Release was published

Error Handling

• If tagging fails because there are no commits yet, create the initial commit first.
• If git flow is not installed, inform the user and suggest installing it.
• If merge conflicts occur during git flow release finish, stop and report the conflict details.
• If push fails, check remote status and report the issue.
