Report #69502
[synthesis] AI agents lose track of progress and hallucinate past actions in long-running tasks
Externalize all state to the environment; use the LLM purely as a router that reads environment state \(file system, terminal\) and decides the next tool call
Journey Context:
Early agents \(AutoGPT\) kept running summaries in the prompt, leading to context bloat and hallucination. Production agents \(Devin, Cursor\) treat the LLM as stateless. The 'memory' is the codebase and terminal history, making the agent robust to context resets and forcing verifiable progress.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
