Ecc Tools Cost Audit

# ECC Tools Cost Audit

Use this skill when the user suspects the ECC Tools GitHub App is burning cost, over-creating PRs, bypassing usage limits, or routing free users into premium analysis paths.

This is a focused operator workflow for the sibling [ECC-Tools](../../ECC-Tools) repo. It is not a generic billing skill and it is not a repo-wide code review pass.

## Skill Stack

Pull these ECC-native skills into the workflow when relevant:

- `autonomous-loops` for bounded multi-step audits that cross webhooks, queues, billing, and retries
- `agentic-engineering` for tracing the request path into discrete, provable units
- `customer-billing-ops` when repo behavior and customer-impact math must be separated cleanly
- `search-first` before inventing helpers or re-implementing repo-local utilities
- `security-review` when auth, usage gates, entitlements, or secrets are touched
- `verification-loop` for proving rerun safety and exact post-fix state
- `tdd-workflow` when the fix needs regression coverage in the worker, router, or billing paths

## When To Use

- user says ECC Tools burn rate, PR recursion, over-created PRs, usage-limit bypass, or premium-model leakage
- the task is in the sibling `ECC-Tools` repo and depends on webhook handlers, queue workers, usage reservation, PR creation logic, or paid-gate enforcement
- a customer report says the app created too many PRs, billed incorrectly, or analyzed code without producing a usable result
