Firebase Performance Dashboard

Generate a self-contained HTML dashboard from BigQuery performance data. This skill uses a helper script for deterministic template assembly.

IMPORTANT: Autonomous Execution

Run all steps without asking for confirmation. Verify data, assemble dashboard, open in browser, and print summary — all in one go. Only pause if data files are missing (tell the user to run /perf-query first). Do NOT ask "Ready to proceed?" or "Should I open the dashboard?"

Step 1: Verify Data Exists

Check that these files exist:

• .perf/config.json
• .perf/data/screen_summary.json
• .perf/data/app_daily_trend.json
• .perf/data/query_metadata.json

If any are missing, STOP: "Query data not found. Run /perf-query first."

Step 2: Assemble Dashboard
