23 tools with consistent verb-noun naming (list_, get_, create_, update_, delete_, add_, remove_, search_). All tools have descriptions (avg ~80 chars, within baseline 34-392). Zod schemas present for all tools with proper type definitions and descriptions. However, output schemas are undocumented, responses are JSON.stringify'd without declared structure. No error handling guidance, no recovery hints, no pagination support despite list tools. Missing tool annotations (readOnlyHint, destructiveHint). Parameter descriptions are adequate but lack format constraints (e.g., date format YYYY-MM-DD stated in description but not enforced via schema). No enum constraints for priority/status fields despite known valid values.

• Add Zod enum constraints for priority (urgent|high|medium|low|none), status (backlog|planned|in-progress|paused|completed|cancelled), and network (0|2). Replace description examples with formal schema constraints.
• Document output schemas for all tools. Define return type structure (e.g., Project { id, name, identifier, description, network, emoji }, Issue { id, name, state_id, priority, ... }). Include in tool descriptions or separate schema registry.
• Add pagination to all list tools: accept limit (1-100, default 20) and offset/cursor parameters; return total_count and next_cursor. Cap results at 50 items per call.
• Wrap api.* calls in try-catch blocks. Return structured error responses with error_code, message, and recovery_hint (e.g., 'Project not found. Try list_projects() to see available projects.').
• Add tool annotations: mark delete_issue and delete_module with destructiveHint=true; mark all read-only tools with readOnlyHint=true. Implement optional dry_run parameter for destructive operations.
