This is a forensic workflow for tracking down cost spikes in the ECC Tools GitHub App repo, the kind that happen when webhooks recurse, PRs multiply, or free users slip past quota gates into premium model calls. It walks you through webhook ingress, queue consumers, PR creation paths, and usage reservation in burn order, not neatness order. The skill pulls in autonomous loops, agentic engineering, and verification loop patterns when the audit crosses multiple subsystems. It's read-only by default and stays scoped to the sibling repo, so you're not accidentally refactoring billing UI while chasing a runaway synchronize event. If you've ever watched CI spend tokens on its own output or seen duplicate jobs fan out from a single push, this is the checklist.
