Install Companion Plugins

Install Companion Plugins

Helps the user install other Claude Code plugins that pair well with Israel-Agent-Skills. The curated list lives in data/companion-plugins.yaml — it's a maintained shortlist, not a general plugin discovery tool.

Procedure

1. Read data/companion-plugins.yaml.
2. For each plugin, check whether it's already installed:

   claude plugins list 2>/dev/null | grep -qE '^\s*{slug}\b'
   

   Label each entry installed / not installed.
3. Present the list to the user as a short menu — one line per plugin with topic, blurb, and install status.
4. Ask which to install (accept all, none, or a comma-separated subset of slugs).
5. If the marketplace isn't registered, add it once (idempotent):

   claude plugins marketplace add {marketplace}
   

6. Install each selected plugin:

   claude plugins install {slug}@{owner}
   

7. Re-check with claude plugins list and report the post-install state.

What this skill does NOT do

• Install plugins without explicit user confirmation.
• Uninstall anything.
• Discover plugins beyond the curated list. If the user asks for unrelated plugins, point them at claude plugins marketplace browse rather than extending this skill ad-hoc.
• Modify Claude Code settings, permissions, or MCP configs.

Extending the list

Add a new entry to data/companion-plugins.yaml with slug, owner, repo, topic, and blurb. The slug must match the target plugin's .claude-plugin/plugin.json name field — verify before adding.
