Context Cost

~1,595Tokens (tool definitions)
~1.3 KBTypical response size
Moderate attention impact (1.25% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

⚪evaluate_payment(amount, recipient, purpose, expected_amount, source_content, ...)

Evaluate a payment intent. MUST be called before executing any payment. ALLOW = you may pay; DENY = you must abandon; ASK = a challenge is returned — relay the reason to the user, then retry with approval_token once the user signs. An optional mandate parameter carries a user-issued single-task authorization.

🟡request_policy_change(agent_id, request, reason)
