Server has 6 tools with basic schemas and descriptions, but significant gaps limit production readiness. All tools have descriptions (10-50 chars, below ideal 50-200 char range) and input schemas with types. However, parameter descriptions are minimal or missing context. Output schemas are undocumented, tools return free-text strings rather than structured JSON. Error handling is generic ('Error retrieving...') with no recovery guidance. No enum constraints on state/priority parameters despite known valid values. Tool naming is clear (verb_noun pattern), but composition issues exist: update_story accepts 10 optional parameters with no guidance on mutual exclusivity or field dependencies.

• Convert all tool outputs from free-text strings to structured JSON objects with typed fields (id, title, state, assignedTo, etc.). Document the output schema in each tool's docstring.
• Add enum constraints to 'state' and 'priority' parameters. Replace description examples with formal JSON Schema enums: state: ['New', 'Active', 'Resolved', 'Closed'], priority: [1, 2, 3, 4].
• Expand tool descriptions to 100-150 characters. Include WHEN to use each tool: 'Retrieve all user stories. Use this for bulk discovery; for targeted searches, use search_stories_by_title or get_stories_by_state.'
• Document update_story parameter relationships. Add a note: 'Provide at least one field to update. Fields are independent; pass only the fields you want to change. Omitted fields are not modified.'
• Replace generic error messages with actionable recovery guidance. E.g., 'User story 999 not found. Verify the ID or call search_stories_by_title to find the correct story.' Categorize errors as retryable (network timeout) vs. user-fixable (invalid ID).
