为代理精心组织和裁剪上下文以提升输出质量与聚焦度。

有意识地组织和裁剪给代理的上下文，确保它在正确的时间看到恰当的信息，从而少幻觉、少跑题、输出更聚焦。适合开始新会话、任务切换、输出质量下降或需要配置规则和上下文文件时使用。关键是把信息切块、优先级化并用模板和规则控制，让 agent 更可靠可控。

# 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
