Report #78252

[architecture] Agent loops endlessly because it forgets the action it just took and repeats it

Adopt a memory-first loop where the agent reads its short-term action history \(scratchpad\) before planning the next step, and explicitly encodes failed actions as negative memory to prevent retrying.

Journey Context:
Action-first agents decide what to do, do it, and then append the result to context. If context fills up and older actions are truncated, the agent loses track and repeats the exact same failing API call. By prioritizing reading the scratchpad of recent actions—and specifically tagging failed attempts with 'DO NOT RETRY'—the agent breaks the loop. The architecture must guarantee that the last N action-outcome pairs are never evicted from working memory.
