Inside Chats: How Lovable's Agents Work Together
Technical guide to Lovable's agent coordination architecture
Lovable published a technical guide explaining the engineering architecture behind Chats, its feature for connecting conversations to app-building work.
The post describes how Lovable's Trajectory System—an append-only, forkable event log modeled after Git—separates what happened from what agents need to know, enabling agents to delegate tasks, maintain context across conversations, and coordinate work through durable inboxes and activations.
From the source
Our architecture separates three things that are easy to conflate: what happened, what an agent needs to know, and when it should run. We record what happened in an append-only, forkable history called a trajectory. Each agent's model context is built from that history, rather than treating the history itself as a prompt. Agents communicate through durable inboxes, while activations arrange for them to run and pick up new work.
