SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables AI agents to reason, plan, test, and integrate actions using a Stratus world-model, reducing reliance on pure LLM prompting and improving reliability in long-horizon tasks.

Core Features & Use Cases

  • Reasoning & Planning: Predicts state transitions and generates action sequences before execution.
  • Testing & Integration: Validates plans and guides integration into web, code, and CLI workflows.
  • Production-Ready: Supports rollout-based planning, debugging, and agent orchestration in real-world environments.

Quick Start

  1. Install and configure the Stratus client and environment variables (STRATUS_API_URL and STRATUS_API_KEY).
  2. Use the rollout endpoint to plan a sequence of actions for a goal, then execute via chat completions with the Stratus model.
  3. Validate outcomes and re-plan if necessary

FAQPage Schema
How do I automate multi-step task planning for AI agents?

Multi-step task planning for AI agents is automated by applying world-model reasoning to predict state transitions and generate action sequences before execution. This approach reduces reliance on pure LLM prompting and improves reliability in long-horizon tasks.

What is a world-model approach for agent planning and testing?

A world-model approach for agent planning predicts outcomes of actions to generate reliable sequences, then validates those plans through integration testing. It shifts reliance away from pure LLM prompting toward structured state transition reasoning.

Do I need Python tooling and API keys to use Stratus for agent rollouts?

Yes, you need Python tooling to access Stratus rollout and chat endpoints. You must configure environment variables STRATUS_API_URL and STRATUS_API_KEY, along with a compatible model name such as stratus-x1ac-small-claude-sonnet-4-5.

Can I use world-model planning for integration tests across web, code, and CLI environments?

Yes, world-model planning supports integration tests across web, code, and CLI environments. It validates generated action sequences and guides integration into real-world workflows, enabling debugging and agent orchestration.

What is the best way to validate AI agent plans before execution?

The best way to validate AI agent plans is using a rollout-based planning endpoint to generate action sequences, then executing via chat completions with the Stratus model. You can validate outcomes and re-plan if necessary.

Why does pure LLM prompting fail for long-horizon agent tasks?

Pure LLM prompting fails for long-horizon agent tasks because it lacks structured state transition reasoning. Applying a world-model generates reliable action sequences and verifies outcomes, reducing errors in complex multi-step workflows.
