Start with deterministic software and add model autonomy only where it improves the result. Many reliable agent systems are carefully designed workflows with explicit tools, bounded choices, and strong feedback loops.
- 01
Start with workflows
Chain model calls and software tools in a visible, testable sequence before introducing open-ended planning.
- 02
Design safe tools
Give every tool a narrow contract, validate its arguments, limit authority, and require confirmation for consequential actions.
- 03
Manage context
Separate working memory, durable knowledge, user preferences, and retrieved evidence. Treat all external content as untrusted input.
- 04
Evaluate trajectories
Test not only the final answer but the sequence of decisions, tool calls, recovery behavior, latency, cost, and safety.
