Report #57977

[synthesis] Agent fails because it assumes a tool or environment state exists from a previous step, but the state was lost or reset

Make state dependencies explicit in the agent's scratchpad. Before executing a state-mutating tool, the agent must list the required preconditions and verify them via a read-only tool call.

Journey Context:
Agents often assume that because they ran a command in step 1, step 5 will share the same environment. Sandboxed environments can reset between steps or API calls. The synthesis is that agents lack persistent proprioception across stateless API calls. The tradeoff is extra read calls, but it guarantees the agent isn't building on a phantom state, which is the root cause of many 'file not found' cascading failures.
