description	Scaffold a new plugin inside an existing marketplace — the shipped dir skeleton, plugin.json, install.sh with the Git-Bash guard, settings.json, and CLAUDE.md; then register it in the catalog and in release-please packages with the catalog extra-files sync.

/add-plugin <name> [description]

Add a new shipped plugin to the current marketplace and wire its release/catalog sync.

Before you start

Read ${CLAUDE_PLUGIN_ROOT}/knowledge/marketplace-conventions.md (§2, §6). Confirm .claude-plugin/marketplace.json exists (run /new-marketplace first if not). Find the repo url from the root CLAUDE.md or ask the user.

Procedure

1. Shipped dir skeleton. Create plugins/<name>/ with .claude-plugin/, skills/, commands/, agents/, hooks/, knowledge/, templates/. Only create the subdirs the plugin will actually use; never create a tests/ dir inside the plugin.

2. Manifest. Copy ${CLAUDE_PLUGIN_ROOT}/templates/plugin/plugin.json to plugins/<name>/.claude-plugin/plugin.json; fill __NAME__, __DESCRIPTION__, __OWNER_NAME__. Version starts at 0.1.0.

3. install.sh. Copy ${CLAUDE_PLUGIN_ROOT}/templates/plugin/install.sh (it includes the Windows/Git-Bash guard); replace __NAME__; chmod +x. Add any plugin-specific need <tool> checks.

4. settings.json + CLAUDE.md. Copy the templates from ${CLAUDE_PLUGIN_ROOT}/templates/plugin/. If the plugin has no hooks, you may omit settings.json. Document the plugin's commands in its CLAUDE.md.

5. Register in the catalog. Append an entry to .claude-plugin/marketplace.json .plugins:

   {
     "name": "<name>",
     "version": "0.1.0",
     "description": "<description>",
     "source": {
       "source": "git-subdir",
       "url": "<repo-url>",
       "path": "plugins/<name>",
       "ref": "<name>-v0.1.0"
     }
   }
   

   Use jq to edit so the JSON stays valid.

6. Register the release package. Add the per-plugin block from ${CLAUDE_PLUGIN_ROOT}/templates/release/release-please-config.json (with __NAME__ replaced) into release-please-config.json .packages, and add "plugins/<name>": "0.1.0" to .release-please-manifest.json. This wires the extra-files catalog sync so version + ref can never drift.

7. Verify + report. Run bash scripts/ci-local.sh (or at minimum bash scripts/structural-check.sh and bats tests/repo). Report the new files and the green gate.

Refuse to place any test/build script inside plugins/<name>/; if the plugin needs tests, put them under repo-root tests/<name>/.
