## What it is
A curated awesome list of agent harness engineering resources, including GitHub projects, tools, benchmarks, and practical guides, with 358 entries across 9 categories. It accompanies a survey proposing the ETCLOVG taxonomy for the agent execution harness layer that wraps LLM agents.

## Use cases
- find open-source agent harness projects
- learn about harness engineering for LLM agents
- discover benchmarks for evaluating AI agents
- study best practices for building reliable long-running agents
- compare agent frameworks and tooling
- research context engineering techniques
- find guides on tool design for AI agents

## When to choose
- you want a curated, regularly verified index of agent harness resources
- you are researching the agent harness ecosystem or survey taxonomy
- you need links to engineering blogs from Anthropic, OpenAI, LangChain, and Cognition

## When to avoid
- you need an actual runnable agent framework rather than a resource list
- you want a maintained software library with a license and releases
- you need non-English-only documentation beyond English and Chinese

## Facets
- artifact type: learning-resource
- maturity: active
- function: agent-framework, developer-tools, documentation
- domain: artificial-intelligence, large-language-models, awesome-lists, developer-tools
- platform: -
- tags: awesome-list, agent-harness, context-engineering, curated-resources, llm-agents, survey, ai-agents, web-server
