ECC Tools Cost Audit

Evidence-first workflow để investigate cost overruns trong ECC Tools GitHub App.

Khi nào dùng

• ECC Tools đang tạo quá nhiều PRs
• Chi phí API bất ngờ tăng cao
• Nghi ngờ quota bypass hoặc premium model leakage
• Duplicate jobs chạy nhiều lần
• GitHub App billing spikes

Workflow

Bước 1 — Freeze scope

# Switch sang ECC-Tools repo
# Identify entry points: webhook router, queue producer/consumer, PR creation, billing path

Bước 2 — Trace ingress

Map tất cả enqueue paths TRƯỚC khi theorize.
Inspect: webhook handlers → queue producers → downstream consumers

Bước 3 — Trace worker

Xác nhận mỗi queued analysis produce gì:
- PR creation?
- Branch creation?
- Token spending?

Bước 4 — Audit burn paths

Pattern	Check
PR multiplication	1 webhook → N PRs?
Quota bypass	Post-enqueue usage reservation?
Premium leakage	Free-tier jobs đang route qua premium models?
Retry burn	Retry logic chạy vòng lặp?
Duplicate jobs	App-generated branches re-entering webhooks?

Bước 5 — Fix theo priority

1. PR multiplication (fix trước)
2. Quota bypass
3. Premium model leakage
4. Duplicate jobs
5. Rerun safety

Bước 6 — Verify hẹp

# Chỉ rerun tests trên changed path
# Không test toàn bộ suite

5 failure modes cao nhất

1. Single queue type xử lý tất cả triggers
2. Post-enqueue usage reservation → quota bypass
3. Free-tier jobs route qua premium providers
4. App-generated branches re-enter webhooks (loop)
5. Expensive work complete trước khi persistence safety check
