Claude Code 2.1.133

This release introduces a new `worktree.baseRef` setting, allowing choice for new worktree branching from `origin/<default>` or local `HEAD`, alongside a default behavior adjustment. Significant stability improvements include resolutions for concurrent sessions dead-ending at 401 and fixes for Remote Control interruptions not fully canceling CLI sessions. Networking capabilities are enhanced with proper respect for proxy settings across the full authentication flow and correct Read/Write/Edit permissions on mapped network drives. Further enhancements address skill discovery for subagents and general interface reliability.

Added

  • Added `worktree.baseRef` setting (`fresh` | `head`) to choose whether `--worktree`, `EnterWorktree`, and agent-isolation worktrees branch from `origin/<default>` or local `HEAD`. **Note:** the default `fresh` changes `EnterWorktree`'s base back to `origin/<default>` (it has been local `HEAD` since 2.1.128) — set `worktree.baseRef: "head"` to keep unpushed commits in new worktrees
  • Added `sandbox.bwrapPath` and `sandbox.socatPath` managed settings (Linux/WSL) to specify custom bubblewrap and socat binary locations
  • Added `parentSettingsBehavior` admin-tier key (`'first-wins' | 'merge'`) to let admins opt SDK `managedSettings` (parent tier) into the policy merge

Improved

  • Improved focus mode behavior
  • Improved memory usage by releasing warm-spare background workers under memory pressure

Changed

  • Hooks now receive the active effort level via the `effort.level` JSON input field and the `$CLAUDE_EFFORT` environment variable, and Bash tool commands can read `$CLAUDE_EFFORT`
  • `claude --help` now lists `--remote-control` alongside `--remote-control-session-name-prefix`

Fixed

  • Fixed parallel sessions all dead-ending at 401 after a refresh-token race wiped shared credentials
  • Fixed `Edit`/`Write` allow rules scoped to a drive root (`C:\`) or POSIX `/` matching incorrectly and always prompting
  • Fixed an unhandled rejection (`ECOMPROMISED`) when a history or session-log file lock is compromised by clock skew or slow disk
  • Fixed pressing Esc during conversation compaction showing a spurious "Error compacting conversation" notification
  • Fixed `HTTP(S)_PROXY` / `NO_PROXY` / mTLS not being respected for the full MCP OAuth flow including discovery, dynamic client registration, token exchange, and token refresh
  • Fixed Read/Write/Edit being denied on mapped network drives passed via `--add-dir` / SDK `additionalDirectories`
  • Fixed Remote Control stop/interrupt from claude.ai not fully canceling the CLI session the same way local Esc does, causing queued messages to never advance after interrupting a stuck tool or prompt
  • Fixed `/effort` in one session unexpectedly changing the effort level of other concurrent sessions, and a related issue where an IDE effort change could be silently dropped
  • Fixed subagents not discovering project, user, or plugin skills via the Skill tool
  • Fixed `claudeCode.claudeProcessWrapper` failing with "Unsupported platform" when the extension build doesn't bundle a Claude binary
