Report #55755

[architecture] Agent reads a file, updates its internal memory, but then a tool fails or the file is externally modified, causing the agent's memory to diverge from ground truth

Treat memory as a cache of external state, not the source of truth. Always validate critical memory against the live environment via tool calls before taking destructive actions. When a tool call fails, immediately update the memory to reflect the failed state, preventing retry loops based on stale assumptions.

Journey Context:
Agents often cache the output of a tool \(e.g., 'created file X'\) in working memory. If the environment changes or the tool succeeded partially, the agent operates on a hallucinated state. The tradeoff is that re-verifying state via tool calls costs latency and API hits, but blind trust in cached memory leads to infinite loops of failure \(e.g., trying to delete a file it thinks exists but was already moved\). Memory must be treated as a read-optimized, eventually-consistent cache, requiring explicit re-validation for write operations.
