# Generating code with verified side-effect boundaries

Implement scoped functions, simulate system calls via test replays, and present verified pull requests

- ResultPropose verified pull request

Write structured code adhering to strict side-effect permissions, execute automated tests against recorded network or filesystem traces in the terminal, and submit clean pull requests accompanied by verification logs for developer review.

## Prompt to start with

BotBentoRecommended

```
Analyze requested functional specifications and write implementations declaring all external effects explicitly. Run replay test suites in the terminal against cached mock environments. Always prompt for user approval before creating branches, opening pull requests on GitHub, or modifying existing repository files.
