Tip: Claude Code 2.1.228 Lets Newer Models Overwrite a File They Haven't Read This Session
Claude Code Changelog·medium signal
The Write tool changed so newer models can overwrite an existing file without a prior Read in the same session, matching Edit's rules; older models still require the read first. The read-before-write guard was a cheap safety net against blind clobbering, so if you relied on it, the protection is now model-dependent rather than universal. Worth re-checking any hook or permission rule that assumed a Read always precedes a Write.
