Version Bumper

Overview

Automates semantic version bumps across all version-bearing files in a Claude Code plugin. Ensures consistency between plugin.json, marketplace.extended.json, and the generated marketplace.json catalog.

Prerequisites

  • jq installed and available on PATH for JSON manipulation
  • Read/write access to .claude-plugin/plugin.json and .claude-plugin/marketplace.extended.json
  • pnpm run sync-marketplace available at the repository root
  • Git installed for optional tag creation

Instructions

  1. Identify the target plugin directory and read the current version from .claude-plugin/plugin.json using jq -r '.version'.
  2. Determine the bump type (major, minor, or patch) from the user request. If unspecified, infer from the nature of changes: breaking changes warrant major, new features warrant minor, and fixes warrant patch.
  3. Parse the current version into its major.minor.patch components and compute the new version according to semver rules (see ${CLAUDE_SKILL_DIR}/references/version-bump-process.md).
  4. Update the "version" field in .claude-plugin/plugin.json with the new version string.
  5. Locate the plugin entry in .claude-plugin/marketplace.extended.json and update its "version" field to match (see ${CLAUDE_SKILL_DIR}/references/update-locations.md).
  6. Run pnpm run sync-marketplace at the repository root to regenerate marketplace.json.
  7. Verify version consistency across all three files by reading each and confirming the version strings match.
  8. Optionally create a git tag (git tag -a "v<new_version>" -m "Release v<new_version>") and prepare a commit message following the chore: Release v<version> convention (see ${CLAUDE_SKILL_DIR}/references/release-workflow.md).

Output

A version bump execution summary containing:

  • The computed transition (old_version to new_version)
  • The exact files updated: .claude-plugin/plugin.json, .claude-plugin/marketplace.extended.json, and regenerated .claude-plugin/marketplace.json
  • Validation confirmation that all files carry the same version
  • Suggested next commands (git add, git commit, git tag, validation scripts)

Error Handling

| Error | Cause | Solution | |---|---|---| | jq: command not found | jq not installed | Install via apt install jq or brew install jq | | Version format invalid | Non-semver string in plugin.json | Correct to x.y.z format before bumping | | Plugin not found in marketplace | Missing catalog entry | Add the plugin to marketplace.extended.json first | | Sync marketplace failure | Schema mismatch or missing fields | Run jq empty on both JSON files to locate syntax errors | | Version mismatch after sync | sync-marketplace did not pick up changes | Verify the plugin name in marketplace.extended.json matches plugin.json exactly |

Examples

Patch bump for a specific plugin: Trigger: "Bump the security-scanner plugin to patch version" Process: Read current version 1.2.3, compute 1.2.4, update plugin.json and marketplace.extended.json, run sync, verify consistency, report success.

Explicit major release: Trigger: "Release version 2.0.0 of plugin-name" Process: Set version to 2.0.0 in all files, sync marketplace, create git tag v2.0.0, prepare commit with chore: Release v2.0.0.

Feature-based minor bump: Trigger: "Increment version for new feature" Process: Detect minor bump, compute 1.2.3 to 1.3.0, update all version locations, sync, validate, report completion.
