Strong naming conventions (verb_noun pattern throughout), clear descriptions for tools and most parameters, and explicit Zod schemas. Tool annotations (readOnlyHint, openWorldHint) demonstrate spec awareness. However, some parameter descriptions lack detail about format/constraints, and output schemas are not documented in the code. The server excels at describing WHAT each tool does and WHEN to use it, meeting the 10-1024 character guideline for tool descriptions (range: 95-237 chars). All 6 tools have explicit descriptions. Parameter count is low (1-2 per tool), reducing cognitive load. Error handling via toolError() is present but responses are not shown, cannot verify if errors include actionable recovery guidance or constraint violations.

• Add JSDoc/TypeScript return type documentation for each tool's response. Example: 'Returns {campaigns: Array<{id: integer, name: string}>}' or link to a Schema registry. This enables LLMs to plan downstream calls and extract fields correctly.
• Enumerate valid values for 'status' parameter in ictbroadcast_campaign_result. Change inputSchema to: status: z.enum(['answered', 'failed', 'no_answer', 'busy', ...]).optional().describe('Optional call-status filter: answered, failed, no_answer, busy, machine, etc.')
• Expand ictbroadcast_stop_campaign description to ~80-100 chars. Example: 'Stop a running campaign by id. Halts live outbound calling immediately. Get campaign_id from ictbroadcast_list_campaigns or monitor status with ictbroadcast_campaign_status.'
• Add pagination guidance to tool descriptions. For ictbroadcast_list_campaigns and ictbroadcast_campaign_result, document: 'Returns up to [X] results. If you need more, contact administrator.' Or add limit/offset parameters if the API supports them.
• Make error responses actionable. In format.ts toolError(), catch specific error types and prepend recovery guidance. E.g., 'Campaign not found. Call ictbroadcast_list_campaigns to see available campaigns.' instead of raw stack traces.
• Document idempotency for write tools. Clarify: 'Calling start_campaign twice with the same campaign_id while running has no additional effect' (or document if it fails/errors instead). This guides agent retry logic.
• Add examples to server instructions that show a multi-step workflow: 'Example: (1) ictbroadcast_list_campaigns → pick campaign_id; (2) ictbroadcast_campaign_status to check if running; (3) ictbroadcast_campaign_summary for totals; (4) ictbroadcast_start_campaign to launch.' This scaffolds agent reasoning.
