gptadmin defines 2 tools with complete schemas and enums. Tool descriptions are present but lack context about WHEN to use them and HOW errors are handled. Parameter descriptions are missing entirely, the schema shows 'action', 'id', 'client_id', etc. with no explanation of what each field controls. Naming is reasonable (action-based: access_clients, operations) but descriptions are terse (42 and 50 chars respectively). The access_clients tool performs sensitive admin operations (issue tokens, bind/unbind, revoke, set_role) and the description does mention 'Explicit admin/owner authority required', but there is no indication of error recovery paths, retryability, or what happens on failure. The operations tool is read-only and well-scoped, but neither tool includes response schema documentation or pagination guidance. This is mid-tier quality: schemas are complete, naming is acceptable, but descriptions and parameter guidance fall short of production standards.

• Add 20-100 char descriptions to all 9 parameters (action, id, client_id, profile_id, role, ttl_days, access_mode, limit, offset). Each description should state the parameter's purpose, format, and constraints.
• Document the response schema for both tools. For access_clients, specify the output of each action (e.g., action=list returns {clients: [{id, profile_id, role, created_at, last_used}]}, action=issue returns {token, expires_at, client_id}). For operations, document operation object structure: {id, action, status, started_at, completed_at, result, error}.
• Expand tool descriptions to 80-200 characters and include recovery hints. Reference error responses the LLM may encounter and suggest next steps (e.g., 'Returns 403 Forbidden if caller lacks admin role, try whoami() to check your role, then ask the hub administrator for a grant.').
• Document parameter dependencies by action. For access_clients, create a table or list showing which parameters are required for each action value (list, issue, bind, unbind, revoke, token, set_role, whoami).
• Add idempotency statements. E.g., 'Idempotent: retrying the same issue call with the same client_id and role is safe, it returns the same token without creating duplicates.'
• Add a 'whoami' action to access_clients description or create a separate tool that returns the caller's current role and permissions. This enables self-service debugging.
• Document pagination limits for operations: 'limit caps results at 200; use offset to paginate. Returned count may be less than limit if fewer operations exist.'
