Three well-named tools with comprehensive descriptions and detailed input schemas. All tools follow verb_noun naming (dk_tender_search, dk_tender_recent, dk_tender_detail). Descriptions are 150 - 350 chars, exceeding the 10 - 1024 baseline and providing clear WHAT/WHEN/WHY context. Input schemas are complete with types, descriptions, and constraints (enums for status/order, numeric ranges for days/limit/page). However, output schemas are not documented, LLMs cannot predict response structure for downstream chaining. Error handling is mentioned ('never throw') but recovery guidance is absent. No tool annotations (readOnlyHint, idempotentHint) despite all three being read-only, safe operations.

• Document output schemas for all three tools. Example for dk_tender_search: { resultatElementDtoList: [{noticeId: string, title: string, buyer: {name: string, cvr: string}, cpvCode: string, noticeType: string, deadlines: {bidDeadline?: string}, estimatedValueDKK?: number, description: string, publicUrl: string}], totalCount: number, page: number }
• Add tool annotations to the McpToolDefinition interface: readOnlyHint: true for all three tools, idempotentHint: true for all three. This signals to agents that these are safe to retry.
• Normalize 'limit' and 'page' parameters to accept only numbers, not strings. Update inputSchema to type: 'number' instead of type: ['number', 'string'].
• Add explicit error response schema and examples. Document that errors return {error: string, retry_hint?: string, retryable: boolean} and provide 2 - 3 concrete examples (e.g., 'API timeout, retry in 5s', 'Invalid CPV code, must be 8 digits').
• In dk_tender_detail description, add: 'Obtain notice_id, notice_version, and notice_publication_number from dk_tender_search or dk_tender_recent results.' This guides multi-step agent planning.
