Examples

Concrete contracts show how to apply AEX to real workflows. Each example pairs a .aex file with inputs, policy, and expected behavior.

Hand-written contracts

• Fix Failing Test — file ops, diff checks, test verification
• Review Pull Request — read-only review with structured output
• Support Ticket Reply — CRM integration, draft-only pattern
• Research Brief — web research with budget enforcement
• Threat Monitor — pre/post verification, git patches, human gates

Generated contracts

You can also generate contracts from natural language:

# Draft from a prompt
aex draft "fix the failing test in src/foo.ts" --model anthropic

# Review what it will do
aex review .aex/runs/fix-test.aex

# Approve and execute
aex review .aex/runs/fix-test.aex --run

Generated contracts are saved to .aex/runs/ and validated against your repo policy before execution.
