Summary

AI summary

Fixed remote MCP tool hangs by aborting after configurable timeout (CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT).

Full changelog

What's changed

  • Added sandbox.credentials setting to block sandboxed commands from reading credential files and secret environment variables
  • Added org-configured model restrictions to the model picker, --model, /model, and ANTHROPIC_MODEL, with a "restricted by your organization's settings" message when a restricted model is selected
  • Added mouse click support to select menus (permission prompts, /model, /config, etc.) in fullscreen mode
  • Fixed --resume failing with "No conversation found" when the original -p run produced no model turns
  • Fixed --json-schema and workflow agent({schema}) structured output: the model can no longer re-call StructuredOutput indefinitely after a successful call, and follow-up turns now reliably return structured output
  • Fixed remote MCP tool calls that hang with no response for 5 minutes — they now abort with an error instead of blocking indefinitely (override with CLAUDE_CODE_MCP_TOOL_IDLE_TIMEOUT)
  • Fixed Claude Code Remote sessions taking ~2.7s longer to start after the agent proxy CA system-trust install was added
  • Fixed pasted Korean/CJK text turning into mojibake in terminals that deliver paste as per-byte extended-key events
  • Fixed /update over Remote Control hanging when a startup trust dialog would have shown
  • Fixed background jobs in the agents view getting stuck in "working" indefinitely when the agent ended a turn without producing structured output
  • Fixed channel connections dropping after navigating to the agents view and back, and after /bg, /tui, or /update
  • Fixed agent stop notifications not correctly attributing who stopped the agent, and improved wording ("finished"/"stopped" instead of "came to rest")
  • Fixed subagent depth tracking: resumed subagents now restore their original spawn depth, and forked subagents now count toward the depth cap
  • Fixed leaked agent worktree registrations: locked .git/worktrees/ entries from killed agents are now cleaned up automatically
  • Fixed Cmd+click not opening URLs in fullscreen mode in Ghostty on macOS
  • Fixed claude --help not listing the --bg/--background flag
  • Fixed Esc, Ctrl-C, and Ctrl-D not working while /share is uploading
  • Improved /install-github-app: GitHub Actions workflow setup is now optional — you can install just the GitHub App and skip the workflow/secret steps
  • Improved /btw with ←/→ arrow navigation to step through earlier answers
  • Improved /plugin to surface plugins you haven't used recently so you can clean them up
  • [VSCode] Fixed extension becoming unresponsive when resuming a large session
