[BUG] ExitPlanMode hangs the UI with "Awaiting input..." after the tool returns a permission stream error

What's Wrong?

I see the issue. The ExitPlanMode tool call failed with: "Tool permission request failed: Error: Tool permission stream closed before response received". This is a bug in Claude Code's plan mode permission handling — not something in PicSift's codebase. It's likely related to the new update you mentioned.

Workaround: I won't use ExitPlanMode going forward this session. The plan is already written at [redacted].

To report the bug: File an issue at https://github.com/anthropics/claude-code/issues describing that ExitPlanMode hangs the UI with "Awaiting input..." after the tool returns a permission stream error. Requires app restart to recover.

should not stop
