Report #39286

[synthesis] Autonomous coding agents breaking the host system or failing due to missing dependencies when running code

Execute all agent-generated code inside an ephemeral, sandboxed container or VM equipped with a dedicated IDE, terminal, and browser.

Journey Context:
Agents that only read and write code without executing it suffer from 'blind' errors—they cannot verify their own work. Cognition's Devin architecture demonstrates that true autonomy requires a persistent, sandboxed compute environment. The agent must be able to install packages, run tests, view browser output, and recover from runtime errors. The tradeoff is infrastructure cost and cold-start latency, but it transforms the agent from a guessing system to an empirical system that closes the feedback loop.
