Claude Code 2.1.141

This release enhances developer workflows with new capabilities and significant stability improvements. Hook-driven desktop notifications, window titles, and bells now provide richer feedback. A new 'Summarize up to here' option helps compress chat context for clearer recent interactions. Agent management is refined with directory-scoped sessions, improved completion states, and background agents preserving permission modes. Numerous fixes address issues from background model fallback and daemon pipe errors on Windows to concurrent session behavior, permission prompt handling, markdown table rendering, and robust plugin/MCP connectivity, making the experience smoother and more reliable for all users.

Added

  • Added `terminalSequence` field to hook JSON output so hooks can emit desktop notifications, window titles, and bells without a controlling terminal
  • Added `CLAUDE_CODE_PLUGIN_PREFER_HTTPS` to clone GitHub plugin sources over HTTPS instead of SSH, for environments without a GitHub SSH key
  • Added `ANTHROPIC_WORKSPACE_ID` environment variable for workload identity federation — scopes the minted token to a specific workspace when the federation rule covers more than one
  • Added `claude agents --cwd <path>` to scope the session list to a directory

Improved

  • Improved spinner feedback during long thinking periods — the spinner now warms to amber after 10 seconds to signal Claude is still working
  • Improved plugin menu navigation: `→`/Tab switch tabs, `↑` moves to the tab strip, and tab headers and search box are clickable in fullscreen mode

Changed

  • `/feedback` can now include recent sessions (last 24 hours or 7 days) for issues spanning more than the current session
  • Rewind menu: added "Summarize up to here" to compress earlier context while keeping recent turns intact
  • Auto mode permission dialog now explains when a `permissions.ask` rule caused the prompt
  • Restored the "view diff in your IDE" option on file-edit permission prompts when an IDE is connected
  • Background agents launched via `/bg` or `←←` now preserve the current permission mode instead of reverting to default
  • `claude agents`: agents that finish work but leave a background shell running now move to Completed instead of staying under Working
  • Voice mode: the WSL error now suggests installing `sox libsox-fmt-pulse` for WSLg users
  • `claude agents`: launching a session no longer fails when the pre-warmed background worker is unhealthy — now falls back to a fresh launch
  • `claude agents` no longer shows empty placeholder sessions left over from backgrounding a fresh REPL, and shows onboarding text when entered via ← with no other agents
  • Empty idle background sessions left over from `←` are now automatically retired by the daemon after 5 minutes

Fixed

  • Fixed background side-queries sending an unavailable Haiku model ID on Bedrock/Vertex/Foundry/gateway when no `ANTHROPIC_SMALL_FAST_MODEL` override is set — now falls back to the main-loop model
  • Fixed `claude daemon status` and `/doctor` on Windows throwing when the daemon pipe key file is locked or unreadable — now shows the underlying error instead of an opaque failure
  • Fixed `claude agents` showing the agent-type list instead of the dashboard when launched through a wrapper that adds flags
  • Fixed `claude agents` opening a crashed session firing redundant dispatches when the working directory was deleted
  • Fixed background jobs on a custom `ANTHROPIC_BASE_URL` gateway not getting auto-named — the namer now uses the main model when no Haiku model is configured
  • Fixed `/model` in one session silently changing the autocompact threshold in other concurrent sessions
  • Fixed switching permission mode while a tool-permission prompt is open not auto-dismissing the prompt when the new setting permits the tool
  • Fixed pressing Enter while a permission/dialog prompt is open also submitting text in the input box
  • Fixed hooks receiving a non-existent `transcript_path` after `EnterWorktree` switches the working directory
  • Fixed markdown tables with cell wrapping falling back to the vertical key-value layout instead of rendering as a bordered grid (regression in 2.1.136)
  • Fixed cancelled prompts being removed from Up-arrow history when auto-restored into the input box, avoiding duplicate entries
  • Fixed prompts cancelled with Ctrl+C/Esc before any response being dropped from Up-arrow history
  • Fixed Ctrl+C not interrupting a running turn while in vim INSERT/VISUAL mode
  • Fixed alternative `chat:submit` keybindings (e.g. `meta+enter`, `ctrl+enter`) not working when `enter` is rebound to `chat:newline`
  • Fixed prompt suggestions being silently disabled when an output style was configured
  • Fixed `spinnerVerbs` setting not being honored in turn-completion messages
  • Fixed AskUserQuestion popup hiding the last line of preceding chat content
  • Fixed Web Search status showing "Did 0 searches" when searches returned errors
  • Fixed multi-line statusline output dropping or corrupting rows when any line exceeds terminal width
  • Fixed light-ansi theme using invisible white for diff context lines on light backgrounds — now uses black
  • Fixed error overlay dumping minified bundle source that hid the original error message
  • Fixed pressing Enter after typing a feedback survey rating digit submitting it as a chat message instead of the rating
  • Fixed pressing `x` on a selected subagent in the agent panel typing into the prompt instead of stopping the agent
  • Fixed session title being derived from plugin monitor notifications before the user's first prompt
  • Fixed "Allowed by PermissionRequest hook" repeating once per tool call under a collapsed read/search group
  • Fixed `/tui` silently dropping running background shells and subagents — now refuses and asks to wait for them to finish
  • Fixed welcome banner showing "API Usage Billing" on Bedrock, Vertex, Foundry, and other third-party providers — now shows the provider name
  • Fixed `/mcp` server list not keeping the focused server visible in short terminals in fullscreen mode
  • Fixed redaction in `/feedback` bundles producing invalid JSON for quoted values like session IDs
  • Fixed desktop and third-party provider sessions incorrectly inheriting `apiKeyHelper`/`ANTHROPIC_AUTH_TOKEN` from host managed-settings
  • Fixed early analytics events being silently dropped when fired before logger initialization
  • Fixed `claude plugin install` failing for plugins whose marketplace `ref` no longer exists upstream when a `sha` is also pinned
  • Fixed plugin details pane showing 0 MCP servers for plugins that declare them via `.mcp.json`
  • Fixed plugin MCP servers with unset config variables showing a generic connection failure instead of a "config issue" message with a fix-it hint; malformed `.mcp.json` entries no longer drop other MCP servers
  • Fixed MCP server configs using POSIX shell parameter expansions (e.g. `${var%pattern}`) being incorrectly flagged as missing environment variables
  • Fixed MCP HTTP/SSE servers returning 403 on connect showing as "failed" instead of "needs auth"
  • Fixed remote MCP servers disconnecting unnecessarily when the optional server-events stream failed to reconnect — tool calls continue over POST
  • Fixed Remote Control MCP connectors all failing with 401 when the worker session token rotated mid-session
  • Fixed Remote Control automatically re-enrolling a trusted device when the server rejects a stale token, instead of looping through `/login`
  • Fixed a race where early OTel spans could be silently dropped in SDK/headless mode with beta tracing enabled
  • Fixed custom `voice:pushToTalk` keybindings and `"space": null` unbinds being silently ignored
  • Fixed Windows Alt+V image paste reporting "no image found" when the clipboard contains a screenshot
  • Fixed SDK "Claude Code native binary not found" on Linux when both glibc and musl platform packages are installed
  • Bedrock: `awsCredentialExport` now always runs when configured instead of being skipped when ambient AWS credentials resolve, fixing auth for cross-account access
  • Fixed in-chat mic showing no feedback when the microphone produced only silence — now shows "No audio detected"
