plugin-version

---

name: plugin-version description: Bump plugin versions in the OpenSaaS Stack monorepo. Invoke whenever any file under claude-plugins/* or .claude-plugin/ is modified — skills, commands, agents, or marketplace config. Plugin versions must be bumped before committing so users who install the plugin get the updated version. Note: this is separate from pr-changeset, which handles npm packages — plugin versions are managed directly in plugin.json and marketplace.json. allowed-tools: Read, Edit, Bash, Grep, Glob

Plugin Version Skill

This skill bumps version numbers for Claude plugins and the marketplace manifest. Plugin versions live directly in JSON files (not changesets) — bumping them is what signals to the marketplace that something changed and triggers users to get the update.

Files This Skill Manages

Changed directory	Files to update
claude-plugins/opensaas-stack/	claude-plugins/opensaas-stack/.claude-plugin/plugin.json (version) AND .claude-plugin/marketplace.json (plugins[name="opensaas-stack"].version)
claude-plugins/opensaas-migration/	claude-plugins/opensaas-migration/.claude-plugin/plugin.json (version) AND .claude-plugin/marketplace.json (plugins[name="opensaas-migration"].version)
.claude-plugin/ root files only	.claude-plugin/marketplace.json (metadata.version only)

Versioning Rules

Patch (bug fixes only)

• Use for: Bug fixes, typo corrections, documentation fixes, minor wording improvements in skill descriptions
• Bump: x.y.Z → x.y.Z+1
• Description: Maximum 2 lines

Minor (features or enhancements)

• Use for: New skills, new commands, new agents, new MCP tools, enhancements to existing capabilities
• Bump: x.Y.z → x.Y+1.0 (reset patch to 0)
• Description: Describe the new capability

Major (breaking changes)

• Use for: Removed skills/commands/tools, changed invocation patterns, incompatible changes
• ONLY when explicitly requested by the user
• Bump: X.y.z → X+1.0.0 (reset minor and patch to 0)

Instructions

Step 1: Identify Changed Plugin Directories

Run git commands to detect which plugin areas changed:

git diff --name-only HEAD
# or for staged changes:
git diff --name-only --cached
# or for all changes relative to main:
git diff --name-only origin/main...HEAD

Look for paths starting with:

• claude-plugins/opensaas-stack/ → opensaas-stack plugin changed
• claude-plugins/opensaas-migration/ → opensaas-migration plugin changed
• .claude-plugin/ → marketplace root changed (check if any file other than version fields changed)

Step 2: Determine Version Bump Type

For each changed plugin:

• Is this a bug fix or correction? → Use patch
• Is this a new skill, command, agent, or capability? → Use minor
• Does this remove or rename something users depend on? → Use major only if user explicitly requested it; otherwise ask

Step 3: Read Current Versions

For each affected plugin, read the current version:

Read: claude-plugins/<plugin-name>/.claude-plugin/plugin.json

The version is in the top-level "version" field.

For the marketplace:

Read: .claude-plugin/marketplace.json

The marketplace metadata version is at metadata.version. Each plugin's marketplace entry version is at plugins[i].version where plugins[i].name matches the plugin name.

Step 4: Calculate New Version

Given the current version string "x.y.z":

• patch: increment z → "x.y.(z+1)"
  • "0.2.0" → "0.2.1"
  • "1.3.4" → "1.3.5"
• minor: increment y, reset z to 0 → "x.(y+1).0"
  • "0.2.0" → "0.3.0"
  • "1.3.4" → "1.4.0"
• major: increment x, reset y and z to 0 → "(x+1).0.0"
  • "0.2.0" → "1.0.0"
  • "1.3.4" → "2.0.0"

Step 5: Edit the JSON Files

For each changed plugin, make two targeted edits using the Edit tool.

Edit 1 — The plugin's own plugin.json:

Find the "version" field near the top of the file and replace just that value.

Example in claude-plugins/opensaas-stack/.claude-plugin/plugin.json:

"version": "0.2.0",

→

"version": "0.2.1",

Edit 2 — The matching entry in marketplace.json:

The plugins array in .claude-plugin/marketplace.json has one object per plugin. Find the object where "name" matches the plugin name and edit its "version" field.

Example: find the block for "name": "opensaas-stack" and edit:

      "version": "0.2.0",

→

      "version": "0.2.1",

Edit 3 (conditional) — Marketplace metadata.version:

Only bump metadata.version if files in the .claude-plugin/ root directory were directly changed (e.g., MARKETPLACE.md, new fields added to marketplace.json structure, owner/metadata fields edited). Do NOT bump it just because plugin versions changed.

Step 6: Verify the Edits

After editing, read back the affected files to confirm:

• The version field shows the new version
• No other fields were accidentally changed
• Both plugin.json and the matching marketplace.json entry show the same new version number

Examples

Example 1: Patch — Fix a typo in a skill description

Changed files: claude-plugins/opensaas-stack/skills/some-skill/SKILL.md

Current version: "0.2.0" → New version: "0.2.1"

Edit claude-plugins/opensaas-stack/.claude-plugin/plugin.json:

• "version": "0.2.0" → "version": "0.2.1"

Edit .claude-plugin/marketplace.json (in the opensaas-stack plugins entry):

• "version": "0.2.0" → "version": "0.2.1"

Do NOT change metadata.version — the marketplace structure itself did not change.

Example 2: Minor — Add a new skill to opensaas-migration

Changed files: claude-plugins/opensaas-migration/skills/new-skill/SKILL.md (new file)

Current version: "0.2.0" → New version: "0.3.0"

Edit claude-plugins/opensaas-migration/.claude-plugin/plugin.json:

• "version": "0.2.0" → "version": "0.3.0"

Edit .claude-plugin/marketplace.json (in the opensaas-migration plugins entry):

• "version": "0.2.0" → "version": "0.3.0"

Example 3: Changes to both plugins

Changed files include both claude-plugins/opensaas-stack/... and claude-plugins/opensaas-migration/...

Determine bump type independently for each plugin based on the nature of its changes. They can be bumped to different versions.

Edit claude-plugins/opensaas-stack/.claude-plugin/plugin.json with its new version. Edit claude-plugins/opensaas-migration/.claude-plugin/plugin.json with its new version. Edit .claude-plugin/marketplace.json twice — once for each plugin's entry.

Example 4: Marketplace-only change

Changed files: .claude-plugin/marketplace.json (added a new top-level field) or .claude-plugin/MARKETPLACE.md

The marketplace structure itself changed, so bump metadata.version.

Current: "version": "1.1.0" → New: "version": "1.1.1" (patch)

Edit .claude-plugin/marketplace.json metadata.version field only. Do NOT change any plugin.json files — no plugin logic changed.

Common Mistakes to Avoid

1. Don't bump metadata.version just because plugin versions changed

   • Plugin version entries in marketplace.json are synced from plugin.json
   • Only bump metadata.version when the marketplace file's own structure changed

2. Don't forget the marketplace.json plugin entry

   • When you bump a plugin.json, always also update the matching entry in marketplace.json
   • The two must stay in sync

3. Don't use major unless explicitly requested

   • New skills and commands are minor, not major
   • Ask the user if you think a major bump is warranted

4. Don't reset patch to 0 on a patch bump

   • patch: 0.2.3 → 0.2.4 (not 0.2.0)
   • minor: 0.2.3 → 0.3.0 (reset patch)
   • major: 0.2.3 → 1.0.0 (reset both)

5. Don't edit unrelated fields

   • Use Edit tool with precise old_string/new_string targeting just the version line
   • Verify after editing that only the version changed

6. Don't create changeset files

   • This skill edits JSON files directly
   • Plugin versions are NOT managed by the npm changeset system

Workflow

When working on plugin changes:

1. Make your plugin code changes
2. Before committing, invoke this skill to bump versions
3. Verify the JSON files show the correct new versions
4. Commit all changed files together (plugin code + plugin.json + marketplace.json)

Troubleshooting

Q: Both plugins changed but for very different reasons — do I use the same bump type? A: No. Evaluate each plugin independently. One might be a patch and the other a minor bump.

Q: I added a new skill AND fixed a bug in the same plugin. Which bump type? A: Use minor (the higher of the two).

Q: How do I know if marketplace metadata.version should be bumped? A: Ask: "Did I change marketplace.json itself beyond just updating plugin version entries?" If you edited owner, metadata.description, added new top-level fields, or changed MARKETPLACE.md — yes. If you only updated plugin version numbers — no.

Q: What if I only changed README.md inside a plugin directory? A: Still bump the plugin version (patch). Documentation is part of the plugin release.

Q: Should this skill be used alongside pr-changeset? A: These are independent. pr-changeset handles npm packages in packages/*. This skill handles Claude plugins in claude-plugins/*. If a PR changes both, use both skills.

Important Notes

• Plugin versions are semver strings stored directly in JSON — there is no automated tooling managing them
• The marketplace.json plugins[].version fields must always match the corresponding plugin.json version fields
• marketplace.json metadata.version is independent and tracks the marketplace manifest itself
• Both plugin.json files and marketplace.json must be committed together in the same commit as the plugin changes
