GeminiCLI/Extension

• Extensions reference – Gemini CLI

  • GeminiCLI's installable bundle, declared in gemini-extension.json with name, version, description, mcpServers, contextFileName, excludeTools, migratedTo, plan, settings, and themes.
  • Other components come from conventional directories rather than manifest fields: GeminiCLI/Hooks from hooks/hooks.json, GeminiCLI/Subagents from .md files in agents/.
  • Subagents are marked a preview feature, which is what keeps this short of a full multi-component package.
