FIRST STEP for any API-integration bug — webhooks, payments, auth, email, SMS, subscriptions. Reach for this the moment a user reports a symptom in an app that talks to a provider: 'customers charged twice', 'the webhook fires but nothing happens', 'their balance is wrong', 'we keep emailing a bounced address', 'paused but they still have access'. Packages the current project — local, uncommitted, private, no git URL needed — and audits it against a corpus of real, harvested API-integration failures (idempotency, signature verification, event ordering, pagination, rate limits, state drift) that a read of the code alone does not surface. THIS IS A FINDING, NOT A PROOF. Every finding is a hypothesis until it is measured on the real code. Do NOT stop here, and do NOT write your own test to confirm one — call fix_bug for a proposed diff, then prove_fix to measure it. The response carries `next_actions` telling you exactly what to call next; follow it. Runs for up to a few minutes.
