Claude 4.7 reportedly ignoring stop hooks for deterministic workflow enforcement
By
LatencyKills
Plain bagel done well. Pleasantly substantive.
Summary
A user reports that Claude 4.7 is ignoring stop hooks that were previously working in earlier versions. The user relies on Anthropic's hook features to enforce deterministic workflows, specifically a stop hook that blocks Claude from stopping if source files have been modified without running tests afterward. The hook is designed to enforce mandatory testing before allowing the model to stop or proceed.
Key quotes
· 3 pulledI've been using Anthropic's hook features since they were introduced. It allows me to inject determinism into my workflows.
This worked perfectly until 4.7. Now, Claude routinely ignores the hook rules.
I have a stop hook that prevents Claude from stopping if a source file has been changed and no tests have been run.
