Bumper

A Claude Code plugin for bumping plugin versions. Automates the tedious release workflow: update version strings across files, generate a changelog, tag, and push.

Installation

/plugin install bumper

Usage

# Bump patch version (default): 1.2.3 → 1.2.4
/bump

# Bump minor version: 1.2.3 → 1.3.0
/bump minor

# Bump major version: 1.2.3 → 2.0.0
/bump major

# Set exact version
/bump 2.0.0

What It Does

When you run /bump, the command:

1. Reads the current version from .claude-plugin/plugin.json
2. Calculates the new version based on your argument
3. Updates version strings in:
   • .claude-plugin/plugin.json — the "version" field
   • README.md — shields.io version badge (version-X.Y.Z-color)
   • CLAUDE.md — version reference in parentheses ((vX.Y.Z))
4. Generates a CHANGELOG.md entry from commits since the last tag, categorized using Keep a Changelog format
5. Commits the changes with message chore: release vX.Y.Z
6. Tags the commit as vX.Y.Z
7. Pushes the commit and tag to remote

Version Patterns

The command looks for these specific patterns in each file:

File	Pattern	Example
plugin.json	"version": "X.Y.Z"	"version": "1.2.0"
README.md	version-X.Y.Z- (badge)	version-1.2.0-blue
CLAUDE.md	(vX.Y.Z)	plugin (v1.2.0) providing...

Files that don't exist or don't contain the expected pattern are silently skipped.
