SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the common issue of AI agents failing to complete tasks due to poorly designed tool action spaces, uninformative observation outputs, and weak error recovery mechanisms that leave agents stuck on failures.

Core Features & Use Cases

  • Action Space Design: Guidelines for building stable, granular tool sets with narrow input schemas and deterministic output shapes to reduce agent confusion and invalid tool calls.
  • Observation Formatting: Standards for structuring tool responses with clear status indicators, one-line summaries, actionable next steps, and artifact references to improve agent decision-making.
  • Error Recovery & Context Budgeting: Contracts for handling error paths with root cause hints and safe retry instructions, plus rules for optimizing context usage to avoid overload and reduce token waste.
  • Use Case: A team building a research AI agent can use this Skill to define micro-tools for high-risk operations like web scraping, format tool outputs to include follow-up actions, and implement context compaction at phase boundaries to boost the agent's task completion rate.

Quick Start

Use the agent-harness-construction skill to redesign the tool action space and observation format for your existing code-editing AI agent to improve its first-attempt success rate.

FAQPage Schema
Why does my AI agent fail to complete tasks or get stuck on tool errors?

AI agent task failure often stems from poorly designed action spaces, uninformative observation formatting, and inadequate error recovery mechanisms that leave agents stuck on failures without actionable next steps.

How do I design an action space for AI agents to reduce invalid tool calls?

Design stable, granular tool sets with narrow input schemas and deterministic output shapes to reduce agent confusion. This action space design minimizes invalid tool calls and improves the first-attempt success rate.

How should I format tool observations to improve agent decision-making?

Format tool observations with clear status indicators, one-line summaries, actionable next steps, and artifact references. This observation formatting provides the context needed for agents to make informed decisions autonomously.

What is context budgeting for autonomous agent systems?

Context budgeting is optimizing context usage to avoid overload and reduce token waste in agent systems. It involves implementing context compaction at phase boundaries to maintain efficient agent operation.

How do I implement error recovery contracts for AI agent tools?

Implement error recovery contracts by handling error paths with root cause hints and safe retry instructions. This prevents agents from getting stuck on failures and guides them toward successful task completion.

Can I use these agent harness guidelines for customer support bots and research agents?

Yes, these agent harness guidelines apply to coding assistants, research agents, customer support bots, and other task-oriented autonomous systems to optimize tooling and boost task completion rates.
