Report #52900

[synthesis] Agent makes decisions based on an outdated representation of the file system or API state, leading to cascading 404s or syntax errors

Mandate a 'state refresh' tool call at the beginning of every high-level reasoning step, rather than relying on the accumulated history of past tool calls.

Journey Context:
Agents maintain state via their context window \(what they read/wrote previously\). But if an external process modifies the environment, or if a previous tool call failed silently, the agent's mental model diverges from reality. It will then issue commands based on phantom files. Simply increasing context size makes this worse \(more stale state to attend to\). The solution is to treat the context window as a cache that must be explicitly invalidated and refreshed from the source of truth at strategic checkpoints.
