**Wait 30-60 seconds** (enough to verify API keys, config parsing, tool initialization), then kill the process.

**Why this is critical:**
- Detects config errors before wasting recording time
- Validates API keys are present and working
- Ensures tools initialize correctly
- Prevents recording a broken session

**If the automation test fails**, fix the issues before proceeding to recording.

from custom_tools._multimodal_tools.run_massgen_with_recording import run_massgen_with_recording

result = await run_massgen_with_recording(
    config_path="massgen/configs/basic/multi/two_agents_gemini.yaml",
    question="What is 2+2?",
    output_format="mp4",  # ALWAYS use mp4 for maximum compatibility
    timeout_seconds=120,
    width=1920,
    height=1080
)

from custom_tools._multimodal_tools.understand_video import understand_video

**Key points:**
- The recording tool saves the video to workspace - use that path for analysis
- You can call `understand_video` multiple times on the same video with different prompts
- Each call focuses on a specific aspect (UX, coordination, status, colors, etc.)

**Step 2: Check token costs**
```bash
cat docs/source/reference/token_budget.rst | grep -A 3 "gemini\|gpt\|claude"
