Four tools with basic schemas and descriptions, but significant gaps in parameter documentation, error handling, and output schema clarity. All tools have descriptions (10-20 chars baseline met), but descriptions lack actionable context for LLM selection. Input schemas present but incomplete: 'mock' parameter lacks description in all tools; 'format_type' enum values not specified. No output schema documented. No error handling guidance. Tools are read-only but lack idempotent/readOnly annotations. Naming is verb-noun compliant but generic ('lookup_*' could be 'query_*' for consistency). No parameter validation rules or constraints documented.

• Add descriptions to 'mock' parameter in all tools: 'If true, use mock threat intel data for testing; if false, query live APIs (requires valid API keys).'
• Document output schema for each tool. E.g., triage_security_alert returns TriageAssessment with fields: severity, mitre_techniques, nist_category, recommendation, confidence_score. Specify types and required fields.
• Convert 'format_type' to a formal enum: {"type": "string", "enum": ["auto", "evtx", "cloudtrail", "syslog"], "description": "Alert format. 'auto' auto-detects; specify explicitly for faster processing."}
• Add error handling guidance: 'If an external API fails, the tool returns partial results with a 'errors' field listing which services failed. Retry with mock=true if live APIs are unavailable.'
• Enhance tool descriptions with decision context: 'lookup_ip_reputation: Use this to assess whether an IP is malicious before blocking it. Returns reputation scores from three sources; score > 60 indicates high risk.'
