Claude Code
  • EnterWorktree now prompts before entering worktrees outside .claude/worktrees/. If your workflow uses worktrees in custom locations, expect a new confirmation dialog that was not there before.

  • MCP per-server request_timeout_ms was silently ignored in fresh sessions. Custom timeouts via --mcp-config or .mcp.json only took effect after a reconnection, so long-running MCP tool calls were hitting the 60s default until now (more below).

  • CLAUDE_CODE_EXTRA_BODY was silently dropped by background agents and claude agents. The shell-exported override now follows the dispatching session, so background workers will actually use your custom API parameters.

  • /doctor is now a comprehensive setup checkup (/checkup is its alias). It can also propose trimming checked-in CLAUDE.md files by cutting content Claude could derive from the codebase.

New in 2.1.206, 2.1.205

2.1.206 (July 10, 2026)

  • Added directory path suggestions to /cd, matching /add-dir behavior
  • Added a /doctor check that proposes trimming checked-in CLAUDE.md files by cutting content Claude could derive from the codebase
  • /commit-push-pr now auto-allows git push to the repo's configured push remote (remote.pushDefault, or the sole remote when only one is configured) in addition to origin
  • Gateway: /login now supports Anthropic-operated public gateway endpoints
  • EnterWorktree now asks for confirmation before entering a git worktree outside the project's .claude/worktrees/ directory
  • Background agents now upgrade to a new version in the background right after a Claude Code update, instead of paying a slow stale-session upgrade when you attach
  • Fixed an expired login failing every model with a misleading "There's an issue with the selected model" error instead of prompting to run /login
  • Fixed claude --resume and --continue not responding to keyboard input on startup
  • Fixed MCP servers configured via --mcp-config or .mcp.json ignoring a per-server request_timeout_ms, which caused long-running MCP tool calls to time out at the 60s default in fresh sessions
  • Fixed CLAUDE_CODE_EXTRA_BODY being silently ignored by claude agents / --bg background workers; the shell-exported override now follows the dispatching session
  • Fixed OAuth MCP servers requiring manual re-authentication after a single failed token refresh
  • Fixed --permission-prompt-tool pointing at an MCP server crashing with "MCP tool not found" on cold start before the server finishes connecting
  • Fixed /model picker rows printing a price for a different model than the row named, and stopped quoting first-party list prices on providers that don't bill them
  • Fixed server-provided model rows being misplaced in the /model picker when an entitlement or allowlist restriction drops the row they were positioned against
  • Fixed desktop sessions getting stuck showing "running" after a slash command was sent mid-turn
  • Fixed keyboard input being ignored in the agents view when a setup prompt appeared before a bare claude --resume on Windows
  • Fixed claude rm leaving the removed job in the daemon roster, causing the row to reappear in claude agents
  • Fixed /remote-control showing "Unknown command" when logged out, it now explains how to sign in
  • Fixed left arrow not stepping back out of a phase or agent in the workflow detail view
  • Fixed /status listing the same broken-install warning twice
  • Fixed false "disused plugin" tips and skewed disuse telemetry for LSP plugins
  • Fixed /doctor's update check to compare Homebrew installs against their cask's channel instead of the settings channel
  • Fixed the fullscreen jump-to-bottom pill suggesting Ctrl+End on macOS, not showing rebound chords, and wrapping over the transcript
  • Bedrock: fixed a multi-minute startup hang when using an awsCredentialExport helper on networks with restricted egress
  • Improved /code-review findings quality on claude-opus-4-8 across all effort levels
  • Improved agents view: status column now uses full terminal width instead of truncating at 64 characters
  • Changed agents view: Ctrl+X now permanently removes a completed session, and sessions no longer render twice; deleted background jobs stay deleted

2.1.205 (July 10, 2026)

  • Added an auto mode rule that blocks tampering with session transcript files
  • Fixed --json-schema silently producing unstructured output when the schema was invalid, and schemas using the format keyword being rejected
  • Fixed a message sent while Claude was working being silently lost when the turn ended at the --max-turns limit
  • Fixed Windows worktree removal deleting files outside the worktree when an NTFS junction or directory symlink existed inside it
  • Fixed background agents staying shown as "failed" or "completed" in the agent list after being resumed with SendMessage
  • Fixed background jobs flipping from "needs input" back to "working" in the agent list when the agent's turn contained no readable text
  • Fixed claude attach erroring when a background agent was mid-upgrade restart instead of waiting for it to come back
  • Fixed session-to-PR linking missing a PR created in a Bash call whose output exceeded the 30K inline limit
  • Fixed claude mcp add-from-claude-desktop getting stuck when a server name contains unsupported characters; invalid names are now reported and remaining servers still import
  • Fixed a plugin LSP server that fails to initialize preventing a valid LSP server from another plugin handling the same file extension
  • Fixed a Windows crash when the directory Claude was launched from is deleted, locked, or unmounted while a command is running
  • Fixed a crash when a file watcher was closed while a directory scan was still in flight
  • Fixed project verify skills being rewritten on every session instead of only when a documented command changed
  • Fixed the agent view rendering one line too high and clipping its header when the job list slightly overflowed the screen
  • Fixed background tasks in the web and mobile Remote Control panels showing stale "Running" status by forwarding full task state on every membership change
  • Improved auto mode to ask before running rm -rf on a variable it can't resolve from context
  • Auto-update binary downloads now stream to disk instead of buffering in memory, cutting the updater's peak memory usage by roughly 400 MB
  • Background task notifications now explicitly state that no human input has occurred, preventing fabricated in-transcript approvals from being acted on
  • Improved agent view: sessions that edit, merge, comment on, or push to an existing PR now link it in claude agents
  • Improved agent view: rows now show a colored state word and a classifier-written headline instead of raw tool call text, and the peek opens with full status including the exact ask for blocked sessions
  • /doctor is now a full setup checkup that can diagnose and fix issues; /checkup is its alias
  • Reserved the "Claude Browser" MCP server name (alongside "Claude Preview") ahead of the Claude Desktop pane rename; user-configured MCP servers can no longer register under either name
  • Fixed Cowork VM-mode local-agent sessions failing to start with "Not logged in, Please run /login" on CLI 2.1.203+

Notes

MCP timeout handling across versions

The per-server request_timeout_ms fix in 2.1.206 closes a gap that opened differently at different layers. In 2.1.187, CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT was added as a global safety net for calls that hang indefinitely (5-minute default). But the per-server config path, which lets you set a shorter or longer timeout for a specific server, was broken in fresh sessions. If you were relying on the global env var as a workaround, you can now move to per-server config for finer control.

Background agent reliability arc

These two releases continue a sustained push on background agent stability that has run through nearly every version since 2.1.196. The headline additions: background upgrades now happen proactively instead of stalling when you attach (2.1.206), CLAUDE_CODE_EXTRA_BODY actually propagates (2.1.206), claude attach waits during upgrade restarts (2.1.205), and stale status indicators in Remote Control panels are fixed (2.1.205). If you had been avoiding --bg because of reliability concerns, the surface is materially better now than it was two weeks ago.

Auto mode tightening

2.1.205 adds a rule blocking tampering with session transcript files, and auto mode now prompts before running rm -rf on a variable it cannot resolve. This follows the pattern from 2.1.183, which blocked destructive git commands and terraform destroy unless explicitly asked. The direction is clear: auto mode is becoming stricter about irreversible operations, which is the right trade.
