Problems / Agents and tools, medium
A finance agent asks a human to approve every payment. Five reviewers take about 20 s each; tasks arrive at 0.5 a second.
Free to open. Runs in your browser, no sign-up.
Success ≥ 95% of tasks, p99 ≤ 3 minutes.
0.5 requests a second for 60 seconds: 100% task (writes).
What each component does in this design, and what calls it. The simulator mimics each one from these settings.
| Component | Its job here | Settings |
|---|---|---|
| Load balancerLoad balancer | Traffic enters here.Calls Agent API.Layer 4 balancers route by IP and port; layer 7 balancers read HTTP and can route by path or header. | – |
| Agent APIApp service | Load balancer forwards to it.Calls Agent orchestrator.Little's law: throughput ≈ concurrency ÷ latency. 200 slots at 50 ms serve about 4,000 req/s. | 3 replicas × 500 slots · timeout 180 s |
| Agent orchestratorAgent orchestrator | Agent API calls it.Calls Model, Human approval.An agent loops: think, call a tool, read the result, repeat until done. | 400 slots · 1 steps |
| ModelLLM endpoint | Agent orchestrator calls it.Latency has two parts: time to the first token, then a steady stream of tokens per second. | 300 streams |
| Human approvalHuman approval | Agent orchestrator calls it.Human-in-the-loop review holds risky actions until a person approves them. | 5 slots |
Try it first. Open one hint at a time if you get stuck.
0.5 × 20 s = 10 reviews in progress.
Ask only for risky actions, or add reviewers.
Add reviewer capacity (and approve only irreversible actions).
