22 tools with consistent naming (verb_noun pattern) and basic schemas, but critical gaps in descriptions and parameter documentation. All tools have input schemas with types, but descriptions are generic (avg ~60 chars, well below 194-char baseline). Parameters lack depth: no enums for constrained values (e.g., HTTP methods in call_rest_api), no format constraints, no dependency documentation. Output schemas are undocumented. Error handling is absent, no recovery guidance, no categorization. Security concerns: connector_id pattern exposes internal IDs; no evidence of secret injection or permission gates. Composition is sound (single responsibility per tool), but missing pagination, result limits, and chaining IDs in responses.

• Expand all parameter descriptions to 50 - 150 chars. Include format, range, and valid values. E.g., 'SQL query to execute (SELECT/INSERT/UPDATE/DELETE; max 10KB; no DDL)' instead of 'SQL query to execute'.
• Document output schemas for all tools. Specify field names, types, and whether results are paginated. E.g., query_database returns {rows: [{col: string}], count: int, next_cursor?: string}.
• Add enum constraints to parameters with known valid values. E.g., query_redis.command should enumerate GET, SET, DEL, HGET, etc., or document the constraint in the description.
• Implement error categorization and recovery guidance. Return {error: string, category: 'retryable'|'user_fixable'|'fatal', suggestion: string}. E.g., 'Connector not found. Available connectors: [...]'.
• Add permission gates and audit logging. Verify caller has authority before executing destructive tools. Log who called what, when, and with which parameters. Implement secret injection for credentials, never expose connector_id as a user-facing parameter.
