Bug Description Bug: Interactive TUI pickers completely freeze (regression in 2.1.115-2.1.119)

Version: Reproduced on 2.1.119. Confirmed NOT present on 2.1.114.

Platform: macOS 26.4, Mac Studio M3, Terminal.app

Affected commands: /mcp (Manage MCP servers), /rewind (conversation rewind picker). Likely all interactive picker/selector
menus.

Symptoms:

  • Picker menu renders correctly with full list
  • Arrow keys have no effect (cursor doesn't move)
  • Enter does not confirm, Esc does not cancel
  • Ctrl+C has no effect
  • Terminal process is still running (closing terminal prompts "are you sure?")
  • Only way out is killing the terminal
  • Happens 100% of the time, not intermittent

Environment: 24 MCP servers configured (some failing: multi-agent-coordinator, pdf-tools). However, the freeze occurs regardless of MCP state - it affects the picker input handling, not the server connections.

Regression confirmed: Downgrading to 2.1.114 via npm install -g @anthropic-ai/[email protected] immediately… Note: Content was truncated.

extent analysis

TL;DR

Downgrading to version 2.1.114 may resolve the issue with interactive TUI pickers freezing.

Guidance

  • The issue seems to be a regression introduced between versions 2.1.114 and 2.1.119, so checking the changelog for those versions might provide insight into the cause.
  • Verify that the issue is not specific to the macOS 26.4 or Mac Studio M3 environment by testing on a different platform if possible.
  • Since downgrading to 2.1.114 resolves the issue, comparing the code changes between 2.1.114 and 2.1.119 could help identify the problematic change.
  • Test other interactive picker/selector menus to confirm if the issue is indeed widespread as suspected.

Notes

The provided information does not include enough technical details about the code or the specific changes made between versions 2.1.114 and 2.1.119, which could help in pinpointing the exact cause of the regression.

Recommendation

Apply workaround: Downgrade to version 2.1.114, as it has been confirmed to resolve the issue with interactive TUI pickers freezing, and there's no clear indication of what the fix in later versions might entail.
