Your own agent loop

Grok 4.5 is trained for tool use and agentic coding. On the API you can build custom loops: model proposes tool calls → your runtime executes → results return → model continues. Keep tools small, idempotent when possible, and least-privileged.

• Separate plan tokens from act tokens when stakes are high.
• Validate structured outputs (JSON schema) before side effects.
• Log every tool call for debugging and evals.
• Human approve for send/delete/pay-class actions.
