The server defines 6 tools with basic structure and all required fields present. However, multiple critical gaps limit production readiness: (1) Tool descriptions are present but lack context about prerequisites, dependencies, and when to use each tool vs. alternatives. (2) Parameter schemas are defined but descriptions are minimal, e.g., 'JQL query string' for get_issues_by_jql does not explain what JQL is, what syntax is valid, or common patterns. (3) Output schemas are completely undocumented, callers have no visibility into response structure, field types, or pagination behavior. (4) Error handling is absent, no guidance on retryability, user-fixable vs. fatal errors, or recovery paths. (5) Tool naming is acceptable (verb_noun pattern) but lacks clarity in distinguishing analytics tools. Overall, definitions are structurally sound but semantically sparse.

• Add complete output schema documentation for each tool. Specify return type (object/array), required fields, field types, and nested structure. Example: 'Returns array of {name: string, key: string, lead: {name, email}, description: string}'.
• Expand parameter descriptions to 50-150 characters. Example: 'JQL query string, Jira Query Language syntax (AND, OR, NOT, field operators). E.g., "project=PROJ AND status=Open". Learn more: https://jira.example.com/jql'.
• Add explicit min/max constraints for numeric parameters. Example: 'maxResults (integer, 1-100, default 50), limit number of returned issues'.
• Document pagination behavior for get_issues_by_jql: 'Total results are available; use startAt + maxResults to iterate. Include total_count in response and next_cursor if more results available.'
• Add error guidance to each tool. Example: 'On invalid JQL syntax, returns 400 with explanation. On auth failure, returns 403, verify Jira token. On rate limit (429), wait and retry.'
• Add tool descriptions that explain when to use each tool. Example for get_issues_by_jql: 'General-purpose Jira issue search. For sprint analytics, use get_sprint_data. For transition timing analysis, use get_transition_times.'
• Validate input constraints early and return actionable error messages. Example: if boardId is invalid, return 'Board not found. Valid boards: [list]. Call get_projects() to discover available boards.'
• Add idempotency guidance: 'All tools are read-only and idempotent, safe to retry without side effects.'
