| description | This skill should be used when managing Claude Code plugin marketplace operations including setup, validation, version syncing, and plugin scaffolding. Sets up marketplace repos to be self-sufficient with their own validation and sync scripts. Triggers on "setup marketplace repo", "install repo scripts", "scaffold plugin", "auto-fix marketplace", "reverse scan", "sync versions", "validate marketplace", "add to marketplace", "check marketplace", or "create plugin". Do NOT use for skill content improvements (use skillsmith), plugin component creation (use plugin-dev), or OmniFocus/Obsidian operations. |

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 outputscripts/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 hookscripts/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
python3 scripts/setup.py install-hook
python3 scripts/setup.py all
Validate (official Anthropic schema)
python3 scripts/repo/validate.py [path]
python3 scripts/repo/validate.py --fix
python3 scripts/repo/validate.py --format json
python3 scripts/repo/validate.py --staged
python3 scripts/repo/validate.py --check-structure
Sync (version alignment)
python3 scripts/repo/sync.py [path]
python3 scripts/repo/sync.py --dry-run
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
