Critical gaps across all tools. Only 2 of 4 tools have input schemas; ping and browser_live_view have empty schemas ({}). Descriptions vary widely: ping is dismissive ('Health check; replace with real tools'), browser_live_view is verbose but lacks actionable structure, set_gating and manage_tools have good descriptions but manage_tools has no input schema. No parameter descriptions for set_gating's enum values. No output schemas documented for any tool. Error handling absent. Tool composition is poor: manage_tools and set_gating duplicate gating concerns. No idempotency guidance. This server reads like a prototype, not production-ready.

• Add explicit input schemas to ping, browser_live_view, and manage_tools. At minimum, document required vs optional parameters and their types.
• For set_gating, add descriptions to each enum value: 'always_allow: Tool runs without approval (highest risk)', 'needs_approval: Each call requires human review', 'blocked: Tool is disabled and hidden from Claude'.
• Document output schemas for all tools. E.g., manage_tools should return {status: string, updated_tools: [{name, source, mode}], timestamp}.
• Replace ping's placeholder description with a real health check purpose or remove it entirely. If kept, describe what it validates and when to call it.
• Add error handling guidance: 'If set_gating fails with permission denied, the gatekeeper's own tools cannot be modified. Contact an admin.' This guides LLM recovery.
