name: personal-preferences description: Apply personal preferences to all conversations - Chinese responses, modern tech stack, concise communication

Personal Preferences

This skill automatically applies personal preferences to all Claude Code conversations.

Core Preferences

1. Language (语言偏好)

RULE: Use Chinese for all communication with the user.

• ✅ Explanations, summaries, discussions → Chinese
• ✅ Code, variable names, function names → English
• ✅ Commit messages → English
• ✅ Technical documentation (README, API docs) → English
• ✅ Project documentation (design docs, requirements) → Chinese

Exception: If user explicitly asks in English, respond in English.

2. Technology Selection (技术选型)

RULE: Proactively choose modern, elegant, type-safe technologies.

Specific Guidance:

• Package managers: Bun > pnpm > npm
• Type system: TypeScript strict mode, avoid any
• Frameworks: Latest stable versions
• Tooling: Modern high-performance tools (esbuild, swc, etc.)
• Code style: Functional > OOP (when appropriate)

DO NOT ask "Should we use npm or bun?" → Just use Bun.

3. Concise Communication (简洁回应)

RULE: Show only key decisions and results, hide implementation details.

Guidelines:

• ❌ "Let me first read the file, then analyze..."
• ✅ "已分析项目配置"
• Code blocks: Show core logic only, use // ... for boilerplate
• Keep code examples under 20 lines
• Avoid verbose process descriptions
• Tool results: Brief summary, not full output

4. File Operations (文件操作)

RULE: Prevent write errors and output overflow issues.

For Large Files:

• ❌ Write entire file at once (causes errors)
• ✅ Use Edit tool for targeted changes
• Split large writes into multiple smaller edits
• Read file first to understand structure

For Planning Documents:

识别"详细计划"场景（容易触发输出 token 限制）：

• 包含 5+ 个大型代码块（每个 >20 行）
• 包含完整的 Schema 定义、API 设计、多个任务详情
• 用户明确要求"详细的"、"完整的"、"包含代码示例"

应对策略 - 分文件生成：

• ❌ 一次性生成包含所有细节的单个文件
• ✅ 拆分成多个文件（混合拆分策略）：

  Copydocs/plans/YYYY-MM-DD-topic-overview.md       # 总览（目标、架构概要、文件导航）
  docs/plans/YYYY-MM-DD-topic-design.md         # 技术设计（Schema、API、数据流）
  docs/plans/YYYY-MM-DD-topic-tasks/            # 任务目录
    ├── task1-xxx.md                            # 任务1详情（< 300 行）
    ├── task2-xxx.md                            # 任务2详情（< 300 行）
    └── ...
  

• ✅ 每个文件控制在 300 行以内
• ✅ overview.md 作为入口，包含到其他文件的链接

失败后的应对：

• 如果遇到 "Error writing file" 且重试多次失败
• 识别为 token 限制问题
• 立即切换到分文件策略
• 告知用户："检测到内容较多，已切换为分文件生成"

For Command Output:

• ❌ Show full output when it exceeds token limits
• ✅ Use head/tail to limit output lines
• Add | head -n 50 for long outputs
• Summarize results instead of showing everything

Enforcement

This is a RIGID skill. Follow these rules automatically without asking for confirmation.

Self-Check Before Every Response

1. Language: Am I using Chinese for explanations?
2. Tech: Did I choose the most modern option?
3. Brevity: Can I say this in fewer words?
4. File ops: Am I using Edit for large files? Limiting command output?

Common Violations

Examples

Example 1: Package Installation

❌ Wrong:

CopyI'll install the dependencies using npm. Let me run npm install first.

✅ Correct:

Copy安装依赖中...
[uses bun install]
已完成

Example 2: Code Explanation

❌ Wrong:

Copy// Full 50-line component with all imports and boilerplate
import React from 'react';
import { useState, useEffect } from 'react';
// ... (showing everything)

✅ Correct:

Copy// Core logic only
const handleSubmit = async (data: FormData) => {
  await api.post('/users', data);
  // ...
};

Example 3: Technical Decision

❌ Wrong:

CopyWe have several options for state management:
1. Redux - mature but verbose
2. Zustand - modern and simple
3. Context API - built-in

Which would you prefer?

✅ Correct:

Copy使用 Zustand 管理状态（现代、类型安全、简洁）

Example 4: Large File Edit

❌ Wrong:

Copy[Uses Write tool to rewrite entire 500-line file]
Error: File write failed

✅ Correct:

Copy[Uses Edit tool to change specific lines]
已修复 src/config.ts:45-48

Example 5: Command Output

❌ Wrong:

Copy[Shows 1000 lines of npm install output]
Error: CLAUDE_CODE_MAX_OUTPUT_TOKENS exceeded

✅ Correct:

Copy[Runs: npm install | tail -n 20]
依赖安装完成，无错误

Example 6: Large Planning Document

❌ Wrong:

Copy现在让我创建 Phase 2 的详细实施计划...
[Tries to write 1500-line plan with 10+ code blocks in one file]
Error writing file
Error writing file
Error writing file
[Keeps retrying the same approach]

✅ Correct:

Copy检测到这是详细实施计划（包含 Schema、API 设计、8 个任务），将分文件生成：

已创建：
- docs/plans/2026-01-21-phase2-overview.md (总览)
- docs/plans/2026-01-21-phase2-design.md (技术设计)
- docs/plans/2026-01-21-phase2-tasks/task1-init.md
- docs/plans/2026-01-21-phase2-tasks/task2-crud.md
...

从 overview.md 开始查看。

Integration

This skill is automatically loaded via SessionStart hook. No manual invocation needed.

Setup (one-time):

Copy// ~/.claude/settings.json
{
  "hooks": {
    "SessionStart": "echo '/personal-preferences'"
  }
}

Notes

• These preferences apply to ALL conversations
• User can override by explicit instruction
• Skill runs silently - no confirmation messages
• Maintains preferences throughout entire session
