What's Wrong?

When using Agent Teams in Claude Code, sub-agents that have finished their work do not disappear from the UI, and the controls for inspecting a sub-agent's work are often unresponsive. As a result, there is no visibility into what each sub-agent did or is currently doing.

Specifically:

• Completed sub-agents continue to appear in the UI as if still active.
• Clicking on a sub-agent's entry/button frequently does nothing — no panel opens, no transcript appears.
• UI clutter accumulates over a session with multiple Agent Teams runs.

What Should Happen?

• Completed sub-agents should be cleared from (or clearly marked as finished in) the UI once their work is done.
• Buttons/entries for each sub-agent should reliably open a view showing that sub-agent's progress, tool calls, and output.

Error Messages/Logs

Steps to Reproduce

1. Open Claude Code inside the Claude Desktop app.
2. Start a task that spawns multiple sub-agents via Agent Teams.
3. Wait for the sub-agents to finish their tasks.
4. Try to click the buttons/entries for individual sub-agents to view their work.

Observed: completed sub-agents remain in the UI; clicks on their entries are often unresponsive, so the sub-agent transcripts cannot be opened.
