Report #76776

[synthesis] Zombie tool loops where agents repeatedly invoke tools with semantically equivalent parameters without state change

Implement "intent hashing" with normalization that ignores surface variations \(timestamps, random IDs, formatting\) to detect semantic duplication, forcing termination or human review when the same intent repeats without progress

Journey Context:
When agents encounter errors or lack of progress, they often fall into "retry loops" - calling the same search with slightly different wording, reading the same file repeatedly hoping for different content, or regenerating similar code blocks. Standard timeout detection misses this because each call is technically different \(different timestamp in parameters, slightly different wording\), but semantically identical. The agent burns tokens and time without realizing it's stuck in a local minimum. Intent hashing must normalize parameters \(ignore timestamps, sort arrays, canonicalize whitespace\) to detect when the agent is "shuffling deck chairs." This requires comparing hashed normalized representations, not raw parameters.
