Three tools with clear verb-noun naming (analyze_user_story, create_test_charter, draft_bug_report) and reasonable descriptions (80-120 chars). All tools have input schemas with Zod validation and type constraints. However, parameter descriptions are sparse or missing entirely, 'feature' and 'risk' in create_test_charter lack descriptions; 'title', 'actual', 'expected' in draft_bug_report lack descriptions. Output schemas are not documented, responses return JSON text without field-level documentation. No error handling guidance, no recovery paths, no validation error messages. Tools are READ_ONLY (good), but lack idempotent/destructive hints. Composition is sound (three independent concerns), but parameter naming could be more explicit (e.g., 'story_text' vs 'story').

• Add descriptions to all parameters. E.g., 'feature: The feature or component name (3+ chars) to explore in this testing session.' 'risk: The specific product risk or failure mode this session should investigate (3+ chars).'
• Document output schemas explicitly. E.g., 'Returns: { acceptanceCriteria: string[], risks: string[], openQuestions: string[] }' for analyze_user_story.
• Add error handling with actionable messages. E.g., if story.length < 20, return 'Story too short (got {length}, need 20+). Provide a full user story with acceptance criteria or feature description.'
• Declare tool annotations in registerTool. Add readOnlyHint: true to all three tools since they do not modify state.
• Standardize parameter naming. Use _text suffix for free-form strings (story_text, feature_text) and _name for identifiers. Add minLength/maxLength constraints to schema descriptions.
