Server has 7 tools with basic descriptions and minimal parameter documentation. All tools are READ_ONLY and return JSON strings. Naming follows verb_noun convention (list_, map_, get_, draft_, query_). However, parameter descriptions are sparse or missing type constraints. No output schemas documented. Error handling is absent from visible code. Tool descriptions average ~80 chars, below the 194-char baseline for A+ tools. Parameters lack enums, ranges, and format constraints. No evidence of input validation or recovery guidance.

• Add explicit output schemas to all tools. Document the JSON structure returned (e.g., list_controls returns {controls: [{id, name, category}], total_count}). This enables LLMs to extract fields reliably.
• Convert 'framework' parameter to an enum: framework: enum[soc2, iso27001, pcidss]. Add similar enums for any other constrained parameters. Remove free-form strings that invite hallucination.
• Expand tool descriptions to 100-200 chars with WHEN/WHY guidance. E.g., 'List all controls for a framework. Call this first to discover available controls before mapping evidence or checking status.'
• Add error handling and recovery hints to tool implementations. Return structured errors like {error: 'control_not_found', control_id: 'SOC2-CC1', suggestion: 'Try list_controls(framework=soc2) to see valid IDs'}.
• Expose pagination parameters (limit, offset/cursor) in query_audit_trail and list_controls. Document the default limit and max allowed in descriptions.
