Worlds —— 用于测试 AI 智能体的 Stripe 与 Zendesk 本地副本

Agent Testing Environments

The frontier of agent verification.

Transcripts are stories. Worlds reads the database. Run your agent against a sealed twin of the systems it touches and get exact, replayable proof of what it did.

Join the public beta Stripe, Zendesk and combined workflows. Free internal testing during beta.

ILLUSTRATIVE WORKFLOW · MOCK DEMO

Watch an agent work. Then grade what it did, not what it said.

Worlds grades the state of the system after the run, not the transcript: what changed, what should have, and the dollars wrong per run. This synthetic example explains the workflow.

All figures and traces are illustrative, not measured agent performance or API references.

WHAT YOU CAN DO

Six things teams do with a world.

Create it

A world starts from a seed: the bundled sample account, or a pseudonymized copy of your own. It is ready in milliseconds and identical every time.

Mark it

A mark records the world's state at that moment. Every diff is measured from a mark, so what your agent did is never mixed up with what was already there.

Let the agent act

Point your agent's stock SDK at the world and hand it a ticket. Same URLs, same errors, same state machine. No code changes.

Read the diff

See what changed since the mark: every refund, credit and cancellation, in dollars, and whose money moved. Replay any run byte for byte.

Break it

Inject rate limits, 500s, lock timeouts, slow responses, an expired key and dropped webhooks. Find out whether your retry logic refunds twice.

Move its clock

Advance 45 days and let renewals bill, prorations settle, cancellations resolve and webhooks fire in order. Then read the diff again.

HOW THIS IS DIFFERENT

How Worlds fits with the tools you already use.

Keep the tools that help you evaluate your agent. Add controlled system state and explicit outcome checks.

EVAL PLATFORMS

Eval platforms help inspect traces and evaluate outputs. Worlds supplies a local system the agent can act on and a record of the resulting state changes. Use that evidence alongside your existing evaluations.

MOCKS AND SANDBOXES

Vendor test modes and sandboxes have different isolation, reset and simulation features. A world gives each test its own starting state, controllable failures and a logical clock, within the connector's documented scope.

CONVERSATION SIMULATORS

Conversation tests exercise what an agent says to a customer. Worlds lets you check the records its actions change, including changes its reply never mentions.

THE CATALOG

Test the systems your agent uses.

Each one is built to be reset, seeded and broken on purpose, and runs beside your agent, not inside it. When your agent says a task is done, Worlds diffs the environment and tells you what really changed.

I. n. A working copy of a system your agent acts on. Same endpoints, same errors, same state machine. No real money and no real customers.

II. v. To run an agent somewhere its mistakes are free.
