Report #22633
[synthesis] Agent generates code without executing it to verify correctness
Execute generated code in an isolated sandbox \(e.g., Docker container\), capture the stdout/stderr, and feed the execution trace back into the agent loop as observation.
Journey Context:
LLMs are notoriously bad at predicting runtime errors or missing dependencies just by reading code. Devin and SWE-agent architectures rely heavily on the 'write -> run -> read error -> fix' loop. The environment is the agent's ground truth. Without execution, the agent hallucinates success. The tradeoff is latency and infrastructure cost, but it is strictly required for reliable autonomous coding.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
