Single tool 'create_interrupt' has a verb-based name and basic schema, but critical gaps undermine quality. Description is 108 chars (acceptable range) but lacks WHEN to use it, prerequisites, or state-modification clarity. Input schema present but parameters lack descriptions, 'action' is typed as object with no guidance on structure; 'risk_level' has no enum constraint despite being a classification field. No output schema documented. No error handling guidance. Tool appears to be a write operation (WRITE risk) but description doesn't explicitly state it modifies state or has irreversible consequences. Missing idempotency guidance and confirmation pattern for high-risk operations.

• Add enum constraint to 'risk_level' parameter: {"enum": ["LOW", "MEDIUM", "HIGH", "CRITICAL"]} with description 'Risk classification. CRITICAL requires immediate review; HIGH requires manager approval; MEDIUM/LOW are logged but do not block execution.'
• Add description to 'action' parameter: 'Object describing the agent action that triggered the interrupt. Must include action_type (string) and any relevant context fields (amount, recipient, target, etc.). Example structure: {"action_type": "fund_transfer", "amount_usd": 15000, "recipient": "supplier_id"}'
• Document output schema in tool definition: 'Returns {interrupt_id (string), status (string: INTERRUPTED), approval_token (string), risk_level (string)}. approval_token is required to approve/reject the interrupt.'
• Revise description to explicitly state: 'Pauses agent execution and creates a pending approval ticket for high-risk operations. This is a write operation with irreversible consequences, once triggered, the agent cannot proceed until a human reviewer approves or rejects the interrupt. Use when an action exceeds autonomy thresholds (e.g., fund transfers, data deletion, external API calls with side effects).'
• Add error handling examples: 'If thread_id is not found, returns error with available thread IDs. If action_payload is invalid, returns error describing required fields. If approval_token generation fails, returns error with retry guidance.'
