Meta describes how it built its new standalone Groups app, Forum, using an AI-native engineering approach where an AI agent participates as a collaborator in the development cycle. The team shifted from a human-in-the-loop to a human-on-the-loop model, where the agent autonomously plans, implements, builds, tests, and corrects code while the engineer supervises and approves outcomes. Key enablers include rigorous planning, automated verification inside the loop, simulated user testing with navigation agents, and agentic production operations for root-cause analysis.

## Evidence

Verbatim from https://engineering.fb.com/2026/10/15/ml-applications/how-meta-built-forum-ai-native-engineering/:

> With human-on-the-loop, the agent runs the iteration itself — plan, implement, build, test, correct, repeat — while the engineer sets the goal, watches the run, steps in when it drifts, and approves the result.
