Failed Payment Recovery Agent with Codex

Stripe work is API work: charge objects, invoice ids, decline codes and subscription statuses, all structured and none of it ambiguous. Codex handles that sort of data manipulation quickly and suits a task scoped this tightly. The written output is deliberately small, one email and one channel line per failed charge.

  5. Business context

    What your business sells and what the customer loses while the payment is unpaid, in your own words. The agent explains the situation from this and claims nothing beyond it.

Why Codex for this agent

Fluent with Stripe objects

Decline codes, invoice references and subscription states are the raw material of this template, and reading them correctly is more than half the job.

Same day the card fails

Involuntary churn is a race against the customer forgetting they ever paid you. A quick harness on a short chain means the draft exists while the failure is still today's news.

Good to know

Before you fork

What happens to a customer who fails four months running?

The agent counts prior failures through list_charges, and your dunning policy decides what that count means, including when to stop emailing and hand the account to a person. Codex will apply the count accurately but it will not invent a rule you never wrote. The staged third-failure case shows you exactly what your wording produces.
