What problem does it solve? When a GitHub App burns cost through recursive PR creation, usage-limit bypass, premium-model leakage, or duplicate queue jobs, this Skill provides an evidence-first audit workflow to trace the exact burn path and fix it in impact order. ## Core Features & Use Cases - Ingress-to-Worker Tracing: Maps webhook router, queue producer, queue consumer, PR creation, usage reservation, and model routing paths before theorizing about root causes. - High-Signal Burn Pattern Detection: Identifies PR multiplication, post-enqueue quota races, free-tier premium routing, retry burn, and app-generated branch recursion. - Burn-Ordered Fixes: Prioritizes fixes by cost impact (PR multiplication, quota bypass, premium leakage, duplicate fanout) with narrow verification steps. - Use Case: A customer reports the app created dozens of duplicate PRs and exceeded their usage quota. Use this Skill to trace the webhook-to-worker path, find that synchronize events re-enqueue analysis on app-owned branches, and stop the recursion. ## Quick Start Audit the ECC Tools repo to find why the GitHub App is over-creating PRs and bypassing usage limits, then report the root cause with exact file paths.
