Usage: bash scripts/butler-eval-weekly.sh [OPTIONS]

Runs the recommended weekly LangFuse evaluation bundle in order:

  1. Regression gate (B1–B8 + MB + B9 oracle) + Dataset sync
  2. WeChat gateway corpus → LangFuse
  3. B9 LIVE fixed set — 13 tasks (LIVE unless --skip-live)
  4. SWE-bench Lite weekly subset (LIVE unless --skip-live)
  5. Assistant cross-dimension health → LangFuse
  6. Delegate failure review checklist (informational)

Options:
  --skip-live         Skip B9/SWE LIVE steps (oracle/corpus only; no LLM cost)
  --no-langfuse       Disable LangFuse push/sync where supported
  --with-experiment   Also run eval experiment variant comparison (slower)
  --lookback=HOURS    Assistant health lookback (default: 168)
  -h, --help          Show this help

Examples:
  bash scripts/butler-eval-weekly.sh
  bash scripts/butler-eval-weekly.sh --skip-live --no-langfuse
