Release Version Update

This skill updates the project version, plugin version, and changelog.

Usage

/release <version-type-or-number> [description]

Version Types

• patch

• Increment patch version (e.g., 0.2.12 → 0.2.13)

• minor

• Increment minor version (e.g., 0.2.12 → 0.3.0)

• major

• Increment major version (e.g., 0.2.12 → 1.0.0)

• X.Y.Z

• Set specific version (e.g., 1.0.0)

Description (Optional)

If provided, use as the changelog entry description. Otherwise, analyze recent commits to generate the changelog.

Workflow

Step 1: Read Current Version

Read pyproject.toml and extract current version:

Look for: version = "X.Y.Z"

Step 2: Calculate New Version

Based on the version type:

• patch: major.minor.patch → major.minor.(patch+1)

• minor: major.minor.patch → major.(minor+1).0

• major: major.minor.patch → (major+1).0.0

• specific: Use the provided version directly

Validate the new version is greater than current (unless forced).

Step 3: Update pyproject.toml

Edit pyproject.toml :

version = "NEW_VERSION"

Step 3.5: Update plugin.json

Edit plugins/synapse-a2a/.claude-plugin/plugin.json :

"version": "NEW_VERSION",

Important: Keep plugin version in sync with pyproject.toml version.

Step 3.6: Update site-docs version references

Update hardcoded version strings in GitHub Pages documentation:

site-docs/getting-started/installation.md — version example in verification section:

You should see the version number (e.g., NEW_VERSION).

site-docs/concepts/a2a-protocol.md — Agent Card JSON example:

"version": "NEW_VERSION",

site-docs/changelog.md — add new version entry at the top of "Recent Highlights" (only if CHANGELOG.md was updated in Step 4-5).

mkdocs.yml — repo_name includes version displayed in GitHub Pages header:

repo_name: s-hiraoku/synapse-a2a vNEW_VERSION

Important: Keep site-docs version in sync with pyproject.toml version.

Step 4: Generate Changelog with git-cliff

Use git-cliff to automatically generate the changelog entry from Conventional Commits:

Preview the generated changelog

python scripts/generate_changelog.py --unreleased --tag vNEW_VERSION --dry-run

Write to CHANGELOG.md

python scripts/generate_changelog.py --unreleased --tag vNEW_VERSION

Step 5: Review and Adjust CHANGELOG.md

Review the generated entry and make manual adjustments if needed:

• Reword entries for clarity

• Add context or PR references if missing

• Remove noise entries that slipped through filters

• Ensure the date is correct: ## [NEW_VERSION] - YYYY-MM-DD

If no git-cliff is available, or for a manual override, write the entry directly using Keep a Changelog format (see below).

Step 6: Report Results

Display:

• Old version → New version

• Changelog entry preview

• Files modified

Examples

Bump patch version

/release patch

Bump minor version with description

/release minor "Add new authentication system"

Bump major version

/release major

Set specific version

/release 1.0.0

Shorthand

/version patch # Same as /release patch
