Marketplace Manager

Marketplace Manager

Manages Claude Code plugin marketplace operations. Makes marketplace repos self-sufficient with their own validation and sync scripts.

| Command | Purpose | |---------|---------| | /mp-sync | Sync plugin versions to marketplace.json | | /mp-validate | Validate marketplace.json against official schema | | /mp-add | Scaffold a new plugin or migrate a legacy skill | | /mp-list | List all marketplace plugins | | /mp-status | Show version mismatches and validation summary |

Architecture

Two-tier script model:

Repo-level scripts -- installed INTO marketplace repos by setup.py, making them self-sufficient:

• scripts/repo/validate.py -- schema validation, bidirectional disk scan, auto-fix, CI output
• scripts/repo/sync.py -- version sync from plugin.json/SKILL.md to marketplace.json

Skill-level scripts -- used by the marketplace-manager skill directly:

• scripts/setup.py -- initialize repos, copy repo scripts, install pre-commit hook
• scripts/scaffold.py -- create new plugins, migrate legacy skills

After setup.py all, a marketplace repo is fully self-sufficient with no runtime dependency on marketplace-manager.

Operations

Setup (initialize a marketplace repo)

python3 scripts/setup.py init --name my-marketplace --owner-name "Team"
python3 scripts/setup.py install-scripts    # Copy validate.py + sync.py into repo
python3 scripts/setup.py install-hook       # Install pre-commit hook
python3 scripts/setup.py all               # All of the above in sequence

Validate (official Anthropic schema)

python3 scripts/repo/validate.py [path]              # Validate marketplace.json
python3 scripts/repo/validate.py --fix                # Auto-add unregistered plugins
python3 scripts/repo/validate.py --format json        # CI/CD output
python3 scripts/repo/validate.py --staged             # Pre-commit version check
python3 scripts/repo/validate.py --check-structure    # Anti-pattern detection

Sync (version alignment)

python3 scripts/repo/sync.py [path]          # Sync versions to marketplace.json
python3 scripts/repo/sync.py --dry-run       # Preview changes without writing

Scaffold (plugin creation and migration)

python3 scripts/scaffold.py create my-plugin --description "Does things"
python3 scripts/scaffold.py create my-plugin --with-commands --with-agents
python3 scripts/scaffold.py migrate skills/old-skill --dry-run
