Edit and Write tools can now route file changes through a new staged-write path instead of writing straight to disk
When editing or writing a file, Claude Code now checks whether the target file has a pending "staged" write context. If it does, the change is routed through a new staging function instead of being written directly to disk. The result comes back marked staged: true, and in that case the usual steps of notifying the code editor (via LSP, the protocol editors use for things like autocomplete and diagnostics) and computing a diff are skipped.
This lets a file change be held in a staged state rather than immediately committed to disk, which matters for workflows that need to review or hold changes before they take effect. If you notice a file edit that doesn't immediately show up on disk or trigger the normal diff/editor updates, this staged path is likely why.
The finding doesn't say what triggers the staged path or what feature relies on it.
