Claude Code v2.1.141: New Environment Variables, Hooks Enhancement, and Bug Fixes

Anthropic shipped Claude Code v2.1.141 with a batch of quality-of-life improvements, new environment variables, and a long list of bug fixes. Here's what's relevant for developers running Claude Code in headless CI, multi-workspace setups, or with custom plugins.

New Environment Variables

CLAUDE_CODE_PLUGIN_PREFER_HTTPS — when set, GitHub plugin sources are cloned over HTTPS instead of SSH. Useful for environments without a configured SSH key.

ANTHROPIC_WORKSPACE_ID — scopes the minted token from workload identity federation to a specific workspace. Required when your federation rule covers multiple workspaces.

Hooks: Desktop Notifications Without a Terminal

Hooks now support a terminalSequence field in JSON output. This lets hooks emit desktop notifications, window title changes, and terminal bell sequences even when no controlling terminal is attached. Useful for long-running background agents in CI or daemon mode.

Agent & Session Improvements

• New claude agents --cwd <path> flag scopes the session list to a specific directory.
• Background agents launched via /bg or ←← now preserve the current permission mode instead of resetting to defaults.
• Agents that finish work but leave a background shell running now appear under Completed, not Working.
• Feedback (/feedback) can include recent sessions (last 24 hours or 7 days) for multi-session issues.

Rewind Menu: Summarize Up to Here

A new option Summarize up to here lets you compress earlier conversation context while keeping recent turns intact — helpful for long sessions without losing recent context.

Miscellaneous Changes

• Spinner now warms to amber after 10 seconds of thinking, so you know Claude hasn't frozen.
• Plugin menu navigation improved: →/Tab cycles tabs, ↑ moves to tab strip, headers and search box are clickable in fullscreen.
• Auto mode permission dialog now explains when a permissions.ask rule triggered it.
• File-edit permission prompts now show the view diff in your IDE option again when an IDE is connected.

Bug Fixes (Highlights)

• Fixed background side-queries sending unavailable Haiku model ID on Bedrock/Vertex/Foundry/gateway — now falls back to the main-loop model.
• Fixed claude daemon status and /doctor on Windows when the daemon pipe key file is locked.
• Fixed /model changes in one session affecting autocompact threshold in other sessions.
• Fixed markdown tables with cell wrapping falling back to key-value layout (regression in 2.1.136).
• Fixed cancelled prompts being dropped from Up-arrow history.
• Fixed Ctrl+C not interrupting a running turn in vim INSERT/VISUAL mode.
• Fixed chat:submit keybindings (meta+enter, ctrl+enter) not working when Enter is rebound to chat:newline.
• Fixed light-ansi theme using invisible white for diff context lines on light backgrounds.
• Fixed error overlay dumping minified bundle source that hid the original error message.
