This server has significant gaps in definition quality. Tool names follow verb_noun convention (good), but descriptions are minimal (10-30 chars, well below the 50-200 char baseline for A+ tools). Parameter descriptions exist but lack detail on constraints, formats, and valid values. Schemas are partially defined using Zod but not fully exposed in the tool registration, the schema property uses Zod shape objects rather than proper JSON Schema. No output schemas documented. Error handling is minimal (basic try-catch with console.error). The server lacks guidance on when to use each tool vs. similar ones, and does not document dependencies between tools (e.g., get_all_users should be called before create_ticket with assigneeId).

• Expand all tool descriptions to 50-200 chars. Include WHAT the tool does, WHEN to use it, and any prerequisites. E.g., 'Create a new Jira project with a unique key. Call get_all_projects first to check for key conflicts. Returns project key and URL.'
• Convert priority and status parameters to enums. Replace 'Priority level of the ticket (e.g., Highest, High, Medium, Low, Lowest)' with an enum constraint: {type: 'string', enum: ['Highest', 'High', 'Medium', 'Low', 'Lowest']}.
• Document output schemas for all tools. E.g., create_project returns {key: string, name: string, self: string}. This enables LLMs to chain tools and extract required fields.
• Add pagination to get_all_projects, get_all_tickets, and get_all_users. Accept limit (default 20, max 100) and offset parameters. Return total count and next_offset so agents can iterate.
• Enhance error messages with recovery guidance. E.g., 'Invalid assigneeId: user not found. Call get_all_users() to find valid user IDs.' This prevents LLM retry loops and guides multi-step planning.
