context-engineering

规划与管理Agent会话上下文以提升输出质量与稳定性。

把给 AI 的上下文精心组织好：什么时候给、给多少、以什么格式给，来提高输出质量并避免跑题或幻觉。在新会话、输出变差或任务切换时使用，也用于配置规则文件和项目上下文。关键是平衡信息量，既防止信息不足，又避免上下文噪声让模型失焦。

# Context Engineering

## Overview

Feed agents the right information at the right time. Context is the single biggest lever for agent output quality — too little and the agent hallucinates, too much and it loses focus. Context engineering is the practice of deliberately curating what the agent sees, when it sees it, and how it's structured.

## When to Use

- Starting a new coding session
- Agent output quality is declining (wrong patterns, hallucinated APIs, ignoring conventions)
- Switching between different parts of a codebase
- Setting up a new project for AI-assisted development
- The agent is not following project conventions
