Report #69922

[synthesis] Agent fails because the environment state changed asynchronously between its planning step and execution step

Implement optimistic locking or state-retrieval immediately prior to the execution step, and abort if the baseline has changed, rather than attempting to execute a stale plan.

Journey Context:
Agents often read a file, decide on an edit, and then execute the edit. In dynamic environments \(or if the user is editing simultaneously\), the file changes between the read and write. The agent applies its diff to the outdated version, corrupting the file. Agents are typically stateless regarding the environment's temporal reality. They need a mechanism akin to ETags in HTTP to ensure the premise of their action still holds true at execution time.
