v2.1.160

What's changed

• Added a prompt before writing to shell startup files (.zshenv, .zlogin, .bash_login) and ~/.config/git/, which could otherwise lead to unintended command execution


• acceptEdits mode now prompts before writing build-tool config files that grant code execution (.npmrc, .yarnrc*, bunfig.toml, .bazelrc, .pre-commit-config.yaml, .devcontainer/, etc.)


• Edit no longer requires a separate Read after viewing a file with grep: single-file grep/egrep/fgrep commands now satisfy the read-before-edit check


• Fixed copy-on-select not writing to the Windows clipboard on WSL — now uses PowerShell interop instead of OSC 52, which terminals like MobaXterm don't support


• Fixed restoring a completed session from claude agents dropping chat history and re-running the original prompt


• Fixed background sessions re-attached after overnight retire losing their conversation and re-running the original prompt


• Fixed claude --bg occasionally failing with "socket missing" when the background daemon was cold-starting on a loaded machine


• Fixed an issue on Windows where the directory a background session was started in could not be deleted after claude rm until the background daemon exited


• Fixed background agents that resumed work being shown under Completed in the agents list


• Fixed claude agents freezing for several seconds when returning to the session list due to the auto-updater re-checking on every exit


• Fixed Esc, arrow keys, and typing becoming unresponsive on Windows when attached to a background session or in the agent view while the host is under heavy CPU load


• Fixed background agents emitting terminal sync-output markers to terminals that don't support them (Apple Terminal, tmux), causing render artifacts when entering a running agent


• Fixed mouse wheel scrolling prompt history instead of the transcript right after opening a session from the agents list


• Fixed CJK IME composition appearing at the bottom-left of the screen instead of at the input caret in the claude agents view


• Fixed valid file:///C:/... links being rewritten to a broken path on Windows terminals with hyperlink support


• Fixed voice mode failing to connect when the project directory or branch name contains non-ASCII or special characters


• Fixed the auto mode unavailability message on third-party providers (Bedrock/Vertex/Foundry) to point to the CLAUDE_CODE_ENABLE_AUTO_MODE opt-in instead of incorrectly blaming the model


• Fixed /effort ultracode incorrectly blaming the dynamic workflows setting when the model cannot run xhigh; ultracode is no longer offered on models that do not support it


• Fixed model-not-found errors suggesting --model when running via the SDK or other hosts where the CLI flag doesn't apply


• Fixed Claude's past replies disappearing from scrollback when resuming a brief mode session with brief mode turned off


• Fixed vim mode p pasting on the line below instead of at the cursor when the register was yanked with v$


• Improved performance of opening recently-inactive background agent sessions in claude agents


• Improved auto mode classifier latency by reducing reasoning on routine actions, lowering the chance of "could not evaluate this action" blocks


• Improved background-session teardown (claude rm/stop, idle reap) to send SIGTERM to running shell subprocesses before SIGKILL, so cleanup handlers run


• Removed CLAUDE_CODE_OPUS_4_6_FAST_MODE_OVERRIDE; the environment variable is now a no-op


• Removed the JetBrains plugin install suggestion from startup


• Renamed the dynamic-workflow trigger keyword from workflow to ultracode. The word "workflow" no longer triggers a run; asking for one in your own words still works. The trigger keyword is highlighted in violet in the prompt input
