Github Tag

Scope Constraints

• Read-write operations — creates, lists, pushes, and deletes git tags.
• Does not create GitHub releases — use gh-release skill for that.
• Does not modify repository settings or branch protections.
• Tags are local until explicitly pushed to the remote.

Input Sanitization

• Tag names: must match semver format (e.g., v1.2.3, v1.0.0-beta.1) with alphanumeric characters, dots, and hyphens only.
• Tag messages: reject null bytes.
• Commit references: must be valid hex SHA prefixes or HEAD.

/gh-tag - Create Version Tags

Create semantic version tags for releases.

Usage

/gh-tag                    # Interactive, suggest next version
/gh-tag v1.2.0             # Create specific tag
/gh-tag v1.2.0 --push      # Create and push immediately
/gh-tag --list             # List existing tags
/gh-tag --delete v1.2.0    # Delete a tag

Workflow

Step 1: Analyze Current State

# Get all tags sorted by version
git tag --sort=-v:refname | head -10

# Get latest tag
LATEST=$(git describe --tags --abbrev=0 2>/dev/null)
echo "Latest tag: $LATEST"

# Count commits since last tag
COMMITS=$(git rev-list $LATEST..HEAD --count 2>/dev/null || echo "0")
echo "Commits since: $COMMITS"

Step 2: Suggest Next Version

Analyze commits since last tag:

# Check for conventional commit types
git log $LATEST..HEAD --format="%s" | while read msg; do
    case "$msg" in
        BREAKING*|*!:*)
            echo "MAJOR" ;;
        feat:*|feat\(*\):*)
            echo "MINOR" ;;
        fix:*|fix\(*\):*)
            echo "PATCH" ;;
    esac
done | sort | uniq -c

Step 3: Create Tag

# Lightweight tag (just a pointer)
git tag v1.2.0

# Annotated tag (recommended - includes metadata)
git tag -a v1.2.0 -m "Version 1.2.0 - Feature description"

# Tag specific commit
git tag -a v1.2.0 abc1234 -m "Version 1.2.0"

Step 4: Push Tag

# Push single tag
git push origin v1.2.0

# Push all tags
git push origin --tags

  [4] Custom version

Select option:

  /gh-tag --delete v0.9.0  # Delete old tag

Delete Tag

Delete tag v0.9.0?

This will delete:
  - Local tag: v0.9.0
  - Remote tag: origin/v0.9.0 (if --remote specified)

Note: If a release exists for this tag, it will become a "draft"
release without a tag.

Proceed? [y/n]

Deleted local tag: v0.9.0
Deleted remote tag: origin/v0.9.0

Semantic Versioning

MAJOR.MINOR.PATCH
  │     │     │
  │     │     └── Bug fixes, patches
  │     └──────── New features, backwards compatible
  └────────────── Breaking changes

Examples:
  v1.0.0   - First stable release
  v1.1.0   - New feature added
  v1.1.1   - Bug fix
  v2.0.0   - Breaking API change

Pre-release:
  v1.0.0-alpha.1
  v1.0.0-beta.1
  v1.0.0-rc.1

Best Practices

1. Always use annotated tags for releases (-a flag)
2. Use consistent format: v1.2.3 or 1.2.3
3. Tag on main/release branch: Not feature branches
4. Include descriptive message: What's in this version
5. Don't delete published tags: Can break others' references

Conventional Commits → Version

Integration

• Use /gh-release to create full release after tagging
• Use /gh-changelog to see what's included since last tag
• Tag after merging all PRs for a release
