SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the challenge of designing effective action spaces, tool definitions, and observation formats for AI agents to improve their planning, tool usage, and error recovery, ultimately leading to higher completion rates.

Core Features & Use Cases

  • Action Space Design: Guides the creation of stable, explicit tool names and schema-first inputs.
  • Observation Formatting: Defines a structured output for tool responses including status, summary, next actions, and artifacts.
  • Error Recovery: Provides a contract for handling errors with root cause hints, retry instructions, and stop conditions.
  • Use Case: When developing a new AI agent that needs to interact with multiple APIs, use this skill to ensure the agent's tools are well-defined, its responses are informative, and it can gracefully handle API errors.

Quick Start

Use the agent-harness-construction skill to design a robust action space for an agent that manages cloud resources.

FAQPage Schema
How do I design an AI agent action space for stable tool execution?

Design an AI agent action space by creating stable, explicit tool names and schema-first inputs. This approach ensures deterministic output shapes and improves the agent's planning and tool execution capabilities.

What is the best way to format AI agent observations for better planning?

Format AI agent observations by structuring tool responses to include status, summary, next actions, and artifacts. This structured observation content directly enables more efficient agent planning and context budgeting.

How do I handle API error recovery in an AI agent?

Handle API error recovery by defining an error handling contract that includes root cause hints, retry instructions, and stop conditions. This guides the agent to gracefully manage API errors and maintain operational stability.

Why does my AI agent fail when interacting with multiple APIs?

AI agents often fail interacting with multiple APIs due to poorly defined tool definitions and uninformative responses. Using schema-first inputs and structured observation formatting improves tool usage and completion rates.

Can I use structured observation formats for AI agent context budgeting?

You can use structured observation formats for AI agent context budgeting by standardizing tool response shapes. Including status, summary, and artifacts ensures efficient agent operation within limited context windows.

When do I need schema-first inputs for AI agent tool definitions?

You need schema-first inputs for AI agent tool definitions when creating a new agent that interacts with multiple APIs. This ensures deterministic output shapes and stable tool naming for reliable execution.
