AskUserQuestion widget doesn't render in Claude Desktop cowork/LAM sessions - spinner hangs indefinitely

Version: Claude Desktop 1.1.3189 (Windows 11 x64, os_version 10.0.26200)

Description:
When the productivity skill (knowledge-work-plugins) calls \AskUserQuestion\ during a cowork session, the interactive widget never renders in the UI. The conversation shows a spinner indefinitely with no way to provide input.

Claude Desktop is aware the question is pending — the logs show:
\\\
lam_tool_permission_stalled
tool_name: 'AskUserQuestion'
seconds_waiting: 300
active_process_count: 2
\\\

But nothing surfaces for the user to interact with.

Steps to reproduce:

1. Open a cowork session with the productivity skill (knowledge-work-plugins) enabled
2. Give a task that causes the skill to call \AskUserQuestion\ (e.g. "add a task" — it asks for confirmation before adding)
3. Observe: spinner runs, no input widget appears

Expected: Interactive question widget renders inline in the conversation with selectable options

Actual: Spinner runs indefinitely. \lam_tool_permission_stalled\ is logged after 300 seconds, confirming Claude Desktop knows the question is pending but never surfaces the UI for it.

Workaround: Hit stop, then re-prompt with explicit enough instructions that the skill doesn't need to ask (e.g. "add this task without asking for confirmation")
