[synthesis] AI agents relying solely on LLM context to track environment state drift and hallucinate file contents or command outputs

Treat the execution sandbox \(browser/terminal\) as the single source of truth; force the agent to read environment state via tools before acting, rather than relying on its internal memory of what it wrote.

Journey Context:
Agents that 'remember' writing a file often fail because the write failed silently, or a subsequent command altered it. Cognition's Devin architecture \(observable through their demos and E2B's public sandbox architecture\) synthesizes a 'read-heavy' agent loop. Instead of assuming the state, the agent constantly executes ls, cat, or browser DOM reads. The LLM's context is merely a scratchpad for planning; the sandbox is the actual state machine. This prevents cascading errors where the agent builds upon a hallucinated or failed state.
