Summary
CodeWhale closed a bug where Plan mode did not hard-block write tools such as file writes, edits, and patches despite policy text saying writes were blocked. The fix strengthens the link between agent-mode labels and actual execution controls.
What changed
CodeWhale addressed issue #3734, where Plan mode blocked some execution paths but not write tools like write_file, edit_file, and apply_patch.
Why it matters
Agent mode systems are only trustworthy when policy text maps to enforcement. Plan-mode write blocking is an important governance control for developers who want reviewable planning before an agent mutates a codebase.
