Quesen defines 5 tools with clear, domain-specific descriptions (avg 156 chars). Tool names use verb_noun pattern (validate, simulate, report, health, version). However, input schemas are partially visible: quesen.validate has a comprehensive schema with 14 parameters, but quesen.simulate, quesen.report, quesen.health, and quesen.version lack visible detailed parameter schemas in the provided source. Descriptions are strong and actionable, but parameter-level descriptions are sparse or missing for nested objects. No output schemas documented. Error handling guidance absent. Security considerations (API keys, permissions) not addressed in tool definitions.

• Document output schemas for all 5 tools. Include field names, types, and descriptions. Example: quesen.validate should document that it returns {decision: string, risk_score: number, confidence: number, fired_rules: array}.
• Expand nested object parameter descriptions in quesen.validate. For each of policy, subject, action, target, tool, permissions, data, signals, provenance, list required subfields and their types. E.g., 'policy: {id: string (required), version: string (required)}'.
• Add descriptions to quesen.health and quesen.version parameters and outputs. E.g., 'quesen.health: Liveness probe. Returns {engine_version: string, uptime_ms: number, transport: string}. Call this to verify the engine is responsive.'
• Add error handling guidance to tool descriptions. E.g., 'quesen.validate returns PROCEED, REVIEW, or SKIP. If REVIEW, examine risk_score and fired_rules to decide next action. Retryable on network errors; non-retryable on policy violations.'
• Clarify API key security in documentation. If X-API-Key header is used (as shown in domain_matrix.py), state: 'API key is passed via X-API-Key header (server-side injection). Never include keys in request payloads.'
