marketplace-dev
Builds and maintains Claude Code plugin marketplaces: converts a skills repo to spec-valid marketplace.json, adds/updates plugin entries, and migrates skills into or between suites. Use for marketplace.json, plugin distribution, one-click install, or "put these skills in a suite". Not for repo health audits (use marketplace-health-check) or cache reconciliation (use skill-governance).
Why this skill is useful
Adds executable scripts for generating and validating marketplace plugins, including specific commands and schema rules not found in public documentation.

What this skill does
marketplace-dev Convert a Claude Code skills repository into an official plugin marketplace so users can install skills via claude plugin marketplace add and get auto-updates. Input: a repo with skills/ directories containing SKILL.md files. Output: .claude-plugin/marketplace.json + validated + installation-tested + PR-ready. Route the task before editing User intent Route --- --- Create marketplace support for a repo that does not have it Follow Phases 0–4 below Add or update an ordinary plugin entry Follow “Maintaining an existing marketplace,” then Phase 3 Consolidate standalone skills into a suite, create a suite from existing skills, move a skill between suites, or rename a skill while moving it Read references/suiteconsolidationworkflow.md completely and follow it instead of the generic Phase 4 constraints Reconcile installed caches after a merged suite migration Invoke daymade-skill:skill-governance and use its post-migration workflow; do not mutate cache state here Audit the whole repository across code, docs, security, PRs, issues, and manifest integrity Invoke marketplace-health-check:marketplace-health-check only when the user requested a broad health check; it is not a prerequisite for a targeted suite migration Phase 0: Evidence Intake Before editing an existing marketplace, collect evidence instead of relying on the default template: 1. Read the current .claude-plugin/marketplace.json. 2. Read this repo's marketplace rules (CLAUDE.md, README install section, changelog). 3. Read official docs for marketplace/plugin path semantics. 4. Use the current conversation as evidence. Mine earlier local Claude Code sessions only when the user explicitly asks for or approves that private source. …
