Marketplace Sync — Git skill for Claude Code

marketplace-sync

`marketplace-sync` is a GitHub Action that syncs [Claude Code](https://docs.anthropic.com/en/docs/claude-code) plugins from upstream [marketplaces](https://code.claude.com/docs/en/plugin-marketplaces), allowing you to gate plugin changes on a pull request.

Usage

Add a workflow like `.github/workflows/marketplace-sync.yml` in the repo you want to use as your curated marketplace:

name: Sync plugins

on:
  schedule:
    - cron: '0 8 * * 1'  # 8AM every Monday
  workflow_dispatch:     # Manual syncing

permissions:
  contents: write
  pull-requests: write

jobs:
  sync:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      # Sync plugins from upstream marketplaces
      - uses: argemma-oss/marketplace-sync@v1.0.0
        with:
          repo: https://github.com/anthropics/claude-plugins-official
          plugins: skill-creator

      - uses: argemma-oss/marketplace-sync@v1.0.0
        with:
          repo: https://github.com/coreyhaines31/marketingskills
          plugins: marketing-skills

      # Generate marketplace.json and README after all syncs
      - uses: argemma-oss/marketplace-sync/generate@v1.0.0
        id: generate
        with:
          marketplace-name: my-curated-marketplace
          readme-path: README.md
          readme-table-prefix: |
            > README.md generated by argemma-oss/marketplace-sync/generate

      # Create a PR if anything changed
      - uses: peter-evans/create-pull-request@v7
        if: steps.generate.outputs.changed == 'true'
        with:
          title: "sync: update plugins from upstream"
          branch: marketplace-sync/update
          commit-message: "[marketplace-sync] Update plugins from upstream"
