对 Codex / Claude Code / GPT 系 Coding Agent 来说:

英文 System Design 文档通常效果更稳定。

原因不是“中文不行”,而是:


一、训练数据分布问题

这些 coding agent 的高质量训练数据,大部分来自:

  • GitHub
  • RFC (Request for Comments 一种技术文档标准格式,最初用于互联网标准制定)
  • ADR(Architecture Decision Record 架构决策记录文档)
  • OpenAPI
  • Architecture Docs
  • Tech Specs
  • PRD
  • Issues
  • StackOverflow

而这些:

绝大部分是英文。

所以 agent 对这种英文结构:

Responsibilities:
Outputs:
Constraints:
Success Criteria:

理解非常强。

它会自动联想到:

  • 模块边界
  • 接口设计
  • 工程分层
  • workflow
  • dependency

二、中文不会“看不懂”

实际上:

现在 GPT-5 / Claude 4 已经完全能理解中文工程文档。

所以:

中文完全能做项目。

尤其:

  • 产品描述
  • PRD
  • workflow
  • prompt
  • 用户需求

都没问题。


但问题在于:

中文工程术语容易“漂移”

比如:

你写:

机会发现

Agent 可能理解成:

  • recommendation
  • lead generation
  • trend analysis
  • opportunity mining

但英文:

Opportunity Discovery

含义会稳定很多。


三、最容易出问题的是“抽象描述”

例如中文:

后面做一些评估

LLM 很容易自由发挥。

但英文:

Evaluate technical feasibility and market viability

边界会清晰很多。


四、真正推荐的方法

不是“全英文”。

而是:

中文思考 + 英文工程定义

这是现在很多 AI 工程团队真实做法。


例如:

你自己用中文整理:

我希望系统从社媒发现用户痛点

然后转成:

The system discovers user pain points from social discussions.

再比如:

中文:

后续进行价值评估

转:

Evaluate market value, technical feasibility, and competitive landscape.

五、最佳实践(非常推荐)

你以后所有 AI 工程项目:

建议采用:


1. 中文思考

用于:

  • brainstorming
  • 产品构思
  • workflow 推演
  • agent 设计

因为:

中文对你认知负担最低。


2. 英文工程文档

用于:

  • README
  • Architecture
  • PRD
  • Codex instructions
  • Prompt templates
  • Agent contracts
  • API schema

因为:

LLM 对英文工程语义最稳定。


六、尤其是这些东西,强烈建议英文

以下内容最好永远英文:


Agent 名称

用:

Collector Agent
Ranking Agent
Evaluation Agent

不要:

收集代理
排序代理

因为英文 agent naming 更稳定。


状态流转

pending
running
completed
failed
retrying

不要中文。


Artifact 类型

Opportunity Report
PRD
Architecture Doc
Task Breakdown

Prompt

Prompt 强烈建议英文。

因为:

英文 prompt:

  • 更短
  • token 更少
  • 语义边界更稳定

七、什么时候中文反而更好

如果:

你的项目:

  • 面向中文用户
  • 分析中文社媒(尤其 Rednote)
  • 提取中文语义
  • 中文情绪分析

那:

数据层必须支持中文

包括:

  • 中文 embedding
  • 中文 chunking
  • 中文 normalization

因为:

中文互联网语义和英文互联网差异极大。


八、你现在最推荐的方式

你现在应该:

用英文写:

  • 项目定义
  • agent contract
  • architecture
  • workflow
  • artifact schema

用中文:

  • 思考
  • 产品推演
  • 灵感记录

这是目前 AI 工程效率最高的方式。

提示词示例

# Project Vision

This project is a multi-agent opportunity discovery and evaluation system.

The system continuously collects discussions, complaints, feature requests, and trend signals from multiple social platforms, then uses a series of AI agents to:

1. Discover emerging user needs
2. Cluster and rank opportunities
3. Evaluate market and technical feasibility
4. Generate structured business and engineering artifacts

The long-term goal is to build an AI-native "opportunity intelligence pipeline" that transforms raw internet discussions into actionable product and engineering outputs.

---

# Core Concept

This is NOT just a chatbot or autonomous agent demo.

The system is designed as an Artifact Pipeline:

Social Signals
    ↓
Need Discovery
    ↓
Clustering & Ranking
    ↓
Evaluation
    ↓
Planning
    ↓
Artifact Generation

The final output of the system is structured artifacts, not conversations.

---

# Information Sources

The MVP should support:

- Reddit

Future versions may support:

- Hacker News
- GitHub Issues
- Twitter/X
- Product Hunt
- Discord
- Telegram
- YouTube comments
- App Store reviews
- Rednote (Xiaohongshu)

---

# MVP Scope

The MVP should remain intentionally small and focused.

DO NOT over-engineer the system.

Avoid:
- distributed systems
- microservices
- autonomous self-improving agents
- complex memory systems
- multi-region infrastructure

# Engineering Principles

The system should prioritize:

1. Simplicity over complexity
2. Deterministic workflows over autonomy
3. Structured artifacts over chat responses
4. Clear state transitions
5. Human-readable outputs
6. Observable workflows
7. Modular agents

---

# Important Constraints

- Keep the MVP implementation small
- Avoid premature optimization
- Prefer explicit workflows over "magic"
- Build for clarity and maintainability
- Every agent must have clear inputs and outputs
- Every workflow stage should produce structured artifacts

---

# Success Criteria for MVP

The MVP is considered successful if it can:

1. Collect real social signals
2. Detect at least one meaningful opportunity
3. Generate useful structured artifacts
4. Demonstrate a complete end-to-end workflow
5. Produce outputs that humans can review and act on

The goal is NOT full autonomy.

The goal is a reliable AI-assisted opportunity pipeline.
