Constraint Handling
Master constraint handling to build safe, compliant agents that operate within defined limits

Defining constraints is only half the battle—you need validation strategies to enforce them. The key question: When and how do you check? Validate too early and you limit flexibility. Validate too late and you've already wasted resources.
Three Validation Stages
Pre-Execution Validation
Check constraints BEFORE taking action. Fastest and safest approach—prevents wasted resources and dangerous operations before they start.
Advantages
- • Catches violations immediately—no wasted compute
- • Prevents dangerous actions before they execute
- • Clear feedback to users/agents about what's allowed
Limitations
- • Can't check dynamic constraints (outcome-dependent)
- • May be too restrictive for exploratory tasks
- • Requires accurate prediction of action results
Example: Before booking a flight, check budget limit. If cost exceeds limit, reject immediately without making API call to booking service.

Validation Best Practices
Fail Fast
Validate critical constraints early. Don't waste resources on operations that will fail later.
Layer Defenses
Use multiple validation stages. Pre + Runtime + Post creates robust safety nets.
Clear Messages
When constraints fail, explain why and how to fix. Help agents/users learn.
Rollback Plans
For runtime/post validation, have compensation strategies ready for violations.
