Problems / Agents and tools, easy

Loading skills every step

The agent loads skills (instructions and scripts) from a registry with 4 slots on every step.

Free to open. Runs in your browser, no sign-up.

Your goals

Success ≥ 95% of tasks, p99 ≤ 90 s.

30 requests a second for 45 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 Skill registry, Model.An agent loops: think, call a tool, read the result, repeat until done.	400 slots · 6 steps
Skill registrySkill registry	Agent orchestrator calls it.A skill registry lists reusable instructions and tools an agent can load when needed.	4 slots
ModelLLM endpoint	Agent orchestrator calls it.Latency has two parts: time to the first token, then a steady stream of tokens per second.	2000 streams

Try it first. Open one hint at a time if you get stuck.

Hint 1

Load on demand, but cache what you load.

Hint 2

Agent work multiplies: tasks a second × steps per task = calls a second on every tool the loop uses.

One way to solve it

Give the skill registry more capacity.
