Belifoa demonstrates solid tool definition fundamentals with complete schemas, clear descriptions, and thoughtful parameter design. All 8 tools have explicit schemas with type definitions and descriptions. Tool names follow verb_noun conventions (get_issue, search_issues, manage_issue). Descriptions are substantive (100-250 chars typical), explaining WHAT the tool does and WHEN to use it. However, several gaps prevent a higher score: (1) manage_issue is a mega-tool combining 8 distinct actions (create/update/comment/close/resolve/delete_comment/archive_comment/bulk_create), violates single-responsibility principle; (2) output schemas are not documented, LLMs cannot predict response structure; (3) error handling lacks recovery guidance; (4) some parameter descriptions could be more prescriptive about constraints (e.g., format validation for dueDate, priority ranges). The server shows production intent but needs refinement for A-grade quality.

• Split belifoa_manage_issue into separate tools: create_issue, update_issue, comment_on_issue, close_issue, resolve_issue, delete_comment, archive_comment, bulk_create_issues. Each tool should have a single, clear action.
• Document output schemas for all tools. Example: belifoa_get_issue should return {id, key, title, description, status, assignee, priority, estimate, dueDate, labels, comments[], ...}. Include field types and which fields are always present.
• Add error recovery guidance to tool descriptions. Example: 'If issue not found, call search_issues() with a partial title. If API rate limit hit, retry after 60 seconds.'
• Enforce parameter constraints in schema. Add 'format': 'date' to dueDate. Add 'minimum': 1, 'maximum': 4 to priority. Add 'pattern' for profileName (alphanumeric + underscore).
• Clarify pagination semantics. Document: 'If endCursor is present in response, pass it as the after parameter to fetch the next page. If endCursor is null, no more results.'
