Claude Code 2.1.235

This release introduces an optional spellcheck setting that underlines misspelled words in your prompt input. Significant performance improvements are also delivered, specifically for memory and CPU usage during background cloud sessions like `/ultrareview`. Users will also notice numerous user interface enhancements, including corrected markdown list item alignment, accurate prompt input highlights, and better consistency for task lists and update notifications. Additionally, permission dialogs now offer clearer options, and Vim mode state is preserved across panel toggles.

Added

  • Added an optional `spellcheck` setting that underlines misspelled words in the prompt input as you type, using your installed `aspell`, `hunspell`, or `ispell`

Improved

  • Improved memory and CPU usage while cloud sessions such as `/ultrareview` or `/autofix-pr` run in the background — their event streams are no longer re-scanned and re-rendered on every update
  • Improved permission dialogs: display text and "don't ask again" options now always match what a grant would cover, and "don't ask again" is withheld when contents cannot be fully displayed
  • Improved the embedded `grep` in native macOS/Linux builds: pathological patterns now fail fast instead of exhausting memory, and `-m N` with `-A/-C` prints correct context
  • Improved the context-limit error to say when auto-compact is off and point to `/config` to re-enable it

Changed

  • Vim mode: NORMAL mode and cursor position are now preserved when toggling the detailed transcript (ctrl+o) or closing a panel
  • Dialogs: arrow keys and Enter pressed in quick succession now select the option you navigated to instead of the previously highlighted one
  • `SendMessage` now refuses messages too large for cross-session delivery up front instead of silently dropping them
  • Remote Control: `claude rc` now applies the same enterprise-gateway availability check as interactive startup

Fixed

  • Fixed whole-prompt-cache invalidation when a language server disconnected or reconnected mid-session
  • Fixed nested markdown list items misaligning at depth 3+ and added a hanging indent to wrapped list items in the terminal UI
  • Fixed prompt input highlights (slash commands, keywords, mentions) appearing shifted by one or more characters in some multi-line prompts
  • Fixed Shift+Tab inside the permission prompt's comment field approving the edit and granting session-wide edit permission instead of closing the field
  • Fixed the Agent tool advertising a general-purpose default in sessions where that agent is unavailable: an omitted `subagent_type` there now gets a clear error listing the available agents
  • Fixed notebook cell delete/replace approval dialogs silently omitting the existing cell content when the notebook or cell could not be read; the dialog now says why
  • Fixed slash commands run while Claude is responding showing HTML entities instead of the actual characters
  • Fixed the prompt footer not showing the "Update installed" restart notice after a background auto-update
  • Fixed the expanded task list (`ctrl+t`) always starting collapsed when resuming or relaunching into a session that still has open tasks
  • Fixed focus jumping between open Claude tabs on its own when a window with several Claude panels is restored or reloaded
