## Browser-Based Questions

When a collab session is active, use `render_ui` for all user interactions.

**Component selection:**
| Question Type | Component |
|--------------|-----------|
| Yes/No | Card with action buttons |
| Choose 1 of 2-5 | RadioGroup |
| Choose 1 of 6+ | MultipleChoice |
| Free text | TextInput or TextArea |

**Example - Yes/No:**
```
Tool: mcp__plugin_mermaid-collab_mermaid__render_ui
Args: {
  "project": "<cwd>",
  "session": "<session>",
  "ui": {
    "type": "Card",
    "props": { "title": "<question context>" },
    "children": [{ "type": "Markdown", "props": { "content": "<question>" } }],
    "actions": [
      { "id": "yes", "label": "Yes", "primary": true },
      { "id": "no", "label": "No" }
    ]
  },
  "blocking": true
}
```

**Terminal prompts only when:** No collab session exists (pre-session selection).

## Overview

**Announce at start:** "I'm using the collab-cleanup skill to close this session."

## Workflow

### Step 1: Identify Current Session

1. Call `mcp__plugin_mermaid-collab_mermaid__list_sessions` to get all sessions across projects:
   ```
   Tool: mcp__plugin_mermaid-collab_mermaid__list_sessions
   Args: {}
   ```
2. Filter results to current project (match `project` field against absolute cwd path)
3. If sessions found for current project:
   - For each session, fetch phase via `mcp__plugin_mermaid-collab_mermaid__get_session_state`:
     ```
     Tool: mcp__plugin_mermaid-collab_mermaid__get_session_state
     Args: { "project": "<cwd>", "session": "<session-name>" }
     ```
   - Display list with phases:
     ```
     Sessions in this project:
     1. glowing-sunny-mesa (phase: rough-draft)
     2. bright-calm-river (phase: implementation)
     ```
   - Ask: "Which session to clean up?" (or if only one, confirm it)
4. If no sessions for curre
