Server implements 7 tools with mixed quality. Strengths: all tools have descriptions (100-200+ chars), most parameters are typed and described, and the schema structure is present. Critical weaknesses: (1) naming convention violations, 4 of 7 tools lack action verbs (health_ping should be check_health; health_env should be check_env_health; lead_ingest should be validate_and_ingest_lead; n8n_workflow_trigger should be trigger_n8n_workflow). (2) Output schemas are completely undocumented, no tool declares what it returns, making it impossible for LLMs to plan downstream calls or validate responses. (3) Parameter descriptions are inconsistent, some are good (e.g., lead_ingest's source_system enum guidance), but others lack detail (n8n_workflow_trigger's 'payload' is just 'JSON payload to send to n8n webhook' with no structure hint). (4) No error handling guidance, tools provide no recovery hints or error classifications. (5) Two tools (lead_ingest, n8n_workflow_trigger) are write operations but lack confirmation/dry-run patterns. Average per-tool score: 58/100.

• Add explicit output schemas for all 7 tools. Document return type (object, string, array) and all fields. Example for health_ping: return type {status: string, uptime_seconds: number, timestamp: string}.
• Rename tools to use action verbs: health_ping → check_gateway_health, health_env → inspect_env_health, lead_ingest → ingest_lead_and_create_ohid, n8n_workflow_trigger → trigger_n8n_workflow.
• Add JSON Schema enum constraints for source_system and channel in lead_ingest. Replace description text guidance with formal schema enums (e.g., 'enum: ["META", "WEB", "WHATSAPP", "TWILIO", "ZOHO_SOCIAL", "ZOHO_CRM"]').
• Document parameter constraints in descriptions. Example: 'first_name: string, 1-100 characters, alphanumeric and spaces only'.
• Add error recovery guidance to all tool descriptions. Example for twilio_webhook_validator: 'If validation fails, verify the X-Twilio-Signature header matches HMAC-SHA1(URL+params, TWILIO_AUTH_TOKEN). Check that TWILIO_AUTH_TOKEN is correctly set in environment.'
• Implement dry-run or confirmation pattern for write operations (lead_ingest, n8n_workflow_trigger). Add optional dry_run=true parameter that returns a preview without persisting.
• Clarify n8n_workflow_trigger payload structure. Document expected JSON shape, required vs optional fields, and provide an example schema in description.
• Add idempotency hints to tools. Example for lead_ingest: 'If the same source_lead_id is ingested twice, the second call returns the same OHID (idempotent). Safe to retry on network failure.'
