Melodic Software — Claude Code plugins

A public Claude Code plugin marketplace of reusable, repo-agnostic skills, hooks, and agents. Each plugin is designed to work in any repository and to be customized by consumers without editing the plugin itself.

Use this marketplace

/plugin marketplace add melodic-software/claude-code-plugins
/plugin install <plugin-name>@melodic-software

Browse and manage with /plugin. To refresh after updates: /plugin marketplace update melodic-software.

Enable plugin suggestions for an organization

Some catalog entries declare relevance signals so Claude Code can suggest the plugin when a session's work matches (matching runs locally; nothing is reported anywhere). Suggestions are opt-in per marketplace: they surface only after an administrator allowlists the marketplace in managed settings — declare the marketplace source AND allowlist its name in the same file:

{
  "extraKnownMarketplaces": {
    "melodic-software": {
      "source": {
        "source": "github",
        "repo": "melodic-software/claude-code-plugins"
      }
    }
  },
  "pluginSuggestionMarketplaces": ["melodic-software"]
}

The source declaration is required for any non-official marketplace: the allowlisted name is ignored if the locally registered marketplace came from a different source, which stops an unrelated catalog from registering under an allowlisted name to get its plugins suggested. Reference: Recommend plugins for your org.

A few personal or external-service plugins install disabled (defaultEnabled: false) until the user opts in with /plugin enable; an existing install is never flipped by catalog changes.

Finding your way

• Not sure which skill to invoke? Start at the skill cheat sheet — a scan-and-go map from what you're doing to the skill to use.
• Plugin catalog — every plugin by category, generated from the manifests and kept in sync by CI. New plugins clear the per-plugin migration gate in docs/MIGRATION-PLAYBOOK.md.
• Catalog taxonomy — the category vocabulary the catalog is grouped by.

What's here

• .claude-plugin/marketplace.json — the marketplace catalog.
• plugins/ — one directory per plugin.
• docs/MIGRATION-PLAYBOOK.md — design charter, extensibility model, the per-plugin migration gate, and the local development loop.
• docs/ — further design records and audits (CI runner routing, extensibility-contract smoke tests, migration audits).
• CLAUDE.md — operating rules for AI agents working in this repo (fresh-docs mandate + plugin design rules).
• docs/OFFICIAL-DOCS.md — canonical index of the official Claude Code doc pages the mandate sends you to.

Official documentation

This repo tracks policy and wiring only; authoritative behavior lives in the official docs, which must be read fresh rather than recalled. Start at the Claude Code plugins guide.
