Critical gaps across all dimensions. Tool descriptions are present but generic (avg ~50 chars, well below 194-char baseline). No visible input schemas in source code, cannot verify parameter types, constraints, or descriptions. Tool names follow verb_noun convention (positive), but lack specificity (e.g., 'invoke_agent' is vague about what happens). No evidence of output schema documentation. Error handling absent, no recovery guidance, categorization, or actionable messages. Security concerns: notify_user and invoke_agent are write operations with no visible permission gates or audit trails. Composition issues: artifact tools (write/edit/delete/read/list/find/move) are well-factored, but agent tools lack clear dependencies and chaining support. STDIO transport caps protocol readiness at 50, further limiting production viability.

• Add explicit JSON Schema input definitions to all 22 tools. Include parameter types (string, number, boolean, array), constraints (enum, minLength, maxLength, pattern), and descriptions (50-100 chars each). Example: invoke_agent should specify agent_id type, task description requirements, and timeout bounds.
• Expand tool descriptions to 100-200 characters. Clarify WHAT the tool does, WHEN to use it vs similar tools, and WHAT it returns. Example: 'invoke_agent: Execute a task on another agent in the system. Use this to delegate work; use get_agent_details to inspect agent state without execution. Returns execution status and result.'
• Add output schema documentation for all tools. Specify return type (object, array, string), required fields, and field types. For list_* tools, include pagination (limit, offset, total_count) and document result caps (e.g., max 50 artifacts per call).
• Implement permission gates for write/destructive operations (invoke_agent, notify_user, delete_artifact, delete_circle_artifact). Verify caller authority before execution. Add scope declarations (e.g., 'requires: agent:invoke, user:notify') to tool metadata.
• Add error handling with recovery guidance. Example: 'Agent not found. Call list_agents() to see available agents.' Categorize errors as retryable (timeout, rate limit) vs user-fixable (invalid agent_id) vs fatal (permission denied).
