[synthesis] Agent retries failed operation without diagnosing root cause, each retry compounding state corruption

Before any retry, explicitly diagnose the failure and check whether the failure changed system state. If the operation is non-idempotent \(creates files, inserts records, modifies configs\), verify idempotency or revert partial state before retrying. Implement a 'stop and reassess' threshold: after 2 failures with the same approach, halt and try a fundamentally different strategy rather than varying parameters.

Journey Context:
An agent tries to create a database migration, fails on a constraint, but doesn't understand the constraint. It retries with slightly different parameters, creating duplicate or conflicting migration files. Or it tries to install a package — partial install fails, it retries, now there's a corrupted node\_modules or venv that makes the retry also fail but with a different error, which the agent also retries. Each retry makes the system state further from the clean state needed for success. The agent is digging a deeper hole with each attempt. The fix has two parts: idempotency awareness \(know whether retrying is safe\) and a reassess threshold \(stop digging\). The reassess threshold is critical because agents tend toward perseverance — they assume failure is transient and retrying will help. But in coding tasks, failure is usually structural, and retrying without understanding is destructive.
