# Meta built Forum with verification-focused coding agents

> Meta engineers built Forum, a separate app for Facebook Groups, by placing an AI agent inside the planning, implementation, testing and verification loop. The company defined success as production-ready changes that build, pass tests and survive review, rather than the amount of code generated.

Agents run automated tests and visual checks before presenting code; engineers set the goal and approve the result. The Forum team gave agents tools to inspect the live view hierarchy and screen elements, aiming to reduce errors such as editing the wrong screen or guessing coordinates.

A separate build flavor keeps prototype code out of the production build while sharing the same codebase and design system. Meta also says agents found and fixed a memory problem during stress testing before launch, roughly halving memory use and page faults in repeated runs.

Meta says the team reached core feature parity in eight weeks. This is the company’s own development account, not a controlled speed comparison with other projects. The post does not claim every stage ran autonomously: engineers remain in some iterations, and shipped work still requires human approval.
