Single tool 'escalate' has a well-structured schema with proper types and descriptions. The tool name is a verb (escalate) and the description (156 chars) clearly explains when to use it. Input schema defines two properties: 'reason' (required, string) and 'detail' (optional, string), both with descriptions. However, the tool lacks output schema documentation, error handling guidance, and examples of what happens after escalation. The description could be more concise for LLM parsing (current length is acceptable but verbose). No parameter constraints (enums, patterns, ranges) are present. The tool is READ_ONLY, which is appropriate for a guardrail pattern.

• Add output schema documenting the escalation response structure (e.g., escalation_id, status, timestamp, next_steps).
• Expand description to include error handling: 'If escalation fails, the agent should retry or log the failure. Escalation is idempotent, calling it twice with the same reason is safe.'
• Add maxLength constraints to 'reason' (e.g., 200 chars) and 'detail' (e.g., 2000 chars) to prevent token waste and guide LLM input formatting.
• Include a concrete example in the description: 'reason: "User requested feature X but it conflicts with policy Y", detail: "User asked for admin access; policy forbids delegation."'
• Document the tool's role in the agent's safety guardrails: 'Call this when uncertain, when instructions conflict, or when a decision requires human judgment. Preferred over guessing.'
