Claude Code 2.1.235 fixes a Shift+Tab that auto-granted edit access
The Aug 18 point release tightens permission dialogs, stops a language-server reconnect from busting your prompt cache, and trims CPU on background reviews.

A stray Shift+Tab was granting session-wide edits
In the permission prompt's comment field, Shift+Tab approved the pending edit and granted session-wide edit permission instead of just closing the field — a silent auto-approve of everything after. 2.1.235 fixes it; update before your next long agent run.
Dialogs now match what you're actually granting
Permission dialog text and the 'don't ask again' option now always reflect the true scope of a grant, and 'don't ask again' is withheld when the contents can't be fully shown. Fewer nasty surprises about what you just approved.
A language-server blip no longer busts your prompt cache
Whole-prompt-cache invalidation was firing whenever a language server disconnected or reconnected mid-session, silently re-billing you for a full cache miss. Now fixed — cheaper, faster turns in editor-connected sessions.
Background reviews stop eating memory and CPU
Long-running cloud sessions like /ultrareview and /autofix-pr no longer re-scan and re-render their whole event stream on every update. Leave them running and expect noticeably lower CPU and memory.
grep -m with context finally prints the right lines
The native macOS/Linux embedded grep now handles -m N alongside -A/-C correctly and fails fast on pathological patterns instead of exhausting memory — fewer searches that wedge mid-task.
