18 tools with consistent naming (verb_noun pattern) and basic descriptions, but significant gaps in schema completeness and parameter documentation. All tools have descriptions (10-150 chars, mostly 50-100), meeting minimum threshold. However, input schemas lack depth: most parameters have type and description, but complex objects (config, payload, billing_address) are underspecified. No output schemas documented anywhere. Error handling is absent, no recovery guidance, no error categorization. Security concerns: no evidence of permission gates on destructive tools (delete_agent, deprovision_resource). Composition is reasonable (single responsibility per tool), but missing idempotency markers and confirmation patterns for irreversible operations.

• Document output schemas for all 18 tools. Specify which fields are returned (e.g., agent_id, created_at, status) and their types. Include chaining IDs (agent_id in list_agents response so agent can be passed to get_agent).
• Add pagination to list_agents, list_resources, list_events: include limit (default 20, max 100), offset, and total_count in response. Cap results at 50 items per call.
• Expand complex object schemas: provision_resource.config should enumerate valid providers (agentmail, stripe, etc.) and document required fields per provider. create_payment_card.billing_address should specify required subfields (street, city, state, zip).
• Add confirmation/dry-run pattern to delete_agent and deprovision_resource. Include a 'confirm' boolean parameter or a separate 'preview_delete_agent' tool that shows what will be deleted before committing.
• Add error handling guidance: document common failure modes (e.g., 'Agent not found. Call list_agents() to see available agents.'), categorize errors as retryable (network timeout) vs user-fixable (invalid agent_id) vs fatal (permission denied), and return actionable error messages with constraints.
