Report #45241

[frontier] Agents accumulate "toxic context residue" where error messages, failed attempts, and corrections pollute the context window, causing conservative or erratic behavior

Implement "Cognitive Hygiene" - establish explicit "context reset" triggers after error cascades \(3\+ consecutive errors\), archiving toxic context to a "graveyard" log while preserving only the successful path and learned constraints, then resume with a compressed "lessons learned" prefix

Journey Context:
Standard practice keeps all error history, causing agents to overfit to transient failures or develop "learned helplessness" where they repeat conservative patterns that avoided prior errors. Cognitive Hygiene treats the context window as a "working memory" that requires periodic flushing of failure modes, similar to human sleep/memory consolidation. By archiving errors to a separate log and continuing with only the distilled "lessons learned," agents avoid the "error spiral" where one mistake causes compensatory errors that compound, eventually filling the context with noise that drowns out the original task.
