Server has 7 tools with basic schemas and descriptions, but significant gaps prevent higher scores. All tools have descriptions (10-50 chars, mostly short), and input schemas are present with type definitions. However, descriptions lack depth, most are single-sentence and under 50 chars, well below the 194-char baseline for A+ tools. No output schemas documented. Parameter descriptions are minimal (e.g., 'The Jira issue key' without format guidance). No error recovery guidance, no enum constraints for constrained inputs (e.g., issueType, transitionName), and no documentation of dependencies between parameters. Tools like updateIssue accept generic 'fields' object with no schema, forcing LLMs to guess valid field names. No pagination guidance for searchIssues or getIssueComments despite returning lists. Missing idempotency and side-effect declarations.

• Document output schemas for all tools. E.g., getIssue returns {issueKey, summary, description, status, assignee, ...}. Include field types and which IDs are needed for downstream calls.
• Expand descriptions to 100-200 chars. Add WHEN to use, WHAT it returns, and any prerequisites. E.g., 'Fetch a Jira issue by its key (e.g., STUDY-11144). Returns issue details including status, assignee, and comments. Use this to inspect an issue before updating or transitioning it.'
• Add enum constraints for issueType (Bug, Task, Story, etc.) and transitionName (In Progress, Done, etc.). Document valid values in parameter descriptions or as JSON Schema enums.
• Add pagination guidance to searchIssues and getIssueComments. Document maxResults limits (e.g., 1-100) and explain how to fetch additional results. Return a total count or next_cursor.
• Enhance error messages with recovery guidance. E.g., 'Transition "In Progress" not found for issue STUDY-11144. Available transitions: To Do, In Progress, In Review, Done. Did you mean "In Review"?'
