Single tool with adequate naming and schema but significant gaps in descriptions and error handling. Tool name 'create-how-to-prompt' follows verb_noun pattern correctly. Input schema uses Zod with proper types (string.min(1)) and parameter descriptions are present but generic. No output schema documented. No error recovery guidance. No idempotency hints despite WRITE risk classification. Missing validation for Markdown format or content length constraints.

• Expand tool description to 100-150 chars explaining WHEN to use it: 'Create a reusable How-To guide in Protomind for your team. Use this to document common development tasks (e.g., adding controllers, setting up databases) so other developers can follow the same steps with AI assistance.'
• Document output schema in code comment or return type: 'Returns {content: [{type: "text", text: string}]} on success. Include created_how_to_id in response for potential future updates/references.'
• Add try-catch around protomind.initMcpImport() with specific error messages: catch network errors → 'Protomind unreachable at http://localhost:3001'; catch validation errors → 'How-To name must be 1-100 chars, body must be valid Markdown'.
• Add Markdown format validation: validate howToBody contains at least one heading (regex /^#+\s/m) and reject if >10000 chars. Return clear error: 'How-To body must be valid Markdown (1-10000 chars, at least one heading).'
• Add tool annotation for destructive behavior: register tool with {destructiveHint: true} to signal to LLM that this creates persistent state. Consider adding optional 'dry_run' parameter to preview without saving.
