source-driven-development

source-driven-development is a skill for Claude Code from vinvcn/addyosmani-agent-skills-zh. It costs 52 tokens per session (1,956 once invoked), scanned A, original, MIT.

A development method that bases framework and library decisions on current official documentation. TDD is not required; the focus is checking the right documentation for the exact versions used.

In plain words
What is it for?
Use it when building or reviewing framework features such as forms, routing, data fetching, state management, or authentication, especially when documented sources and citations matter.
Why use it?
It reduces mistakes caused by outdated training knowledge, removed APIs, or version-specific differences, and makes technical choices easier to verify.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

source-driven-development scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

来源驱动开发

概览

每个框架特定的代码决策都必须有官方文档支撑。不要凭记忆实现;要验证、引用,并让用户看到你的来源。训练数据会过时,API 会废弃,最佳实践会演进。这个 skill 确保用户拿到可信的代码,因为每个模式都能追溯到他们可以检查的权威来源。

何时使用

  • 用户希望代码遵循某个框架的当前最佳实践
  • 构建样板代码、starter code,或会被复制到整个项目中的模式
  • 用户明确要求有文档、有验证或“正确”的实现
  • 实现框架推荐做法很重要的功能(表单、路由、数据获取、状态管理、认证)
  • 审查或改进使用框架特定模式的代码
  • 任何你准备凭记忆编写框架特定代码的时候

何时不使用:

  • 正确性不依赖特定版本(重命名变量、修 typo、移动文件)
  • 在所有版本中行为相同的纯逻辑(循环、条件、数据结构)
  • 用户明确希望速度优先于验证(“just do it quickly”)

流程

DETECT ──→ FETCH ──→ IMPLEMENT ──→ CITE

 What       Get the    Follow the   Show your
 stack?     relevant   documented   sources
            docs       patterns

第 1 步:检测技术栈和版本

读取项目的依赖文件以识别精确版本:

package.json    → Node/React/Vue/Angular/Svelte
composer.json   → PHP/Symfony/Laravel
requirements.txt / pyproject.toml → Python/Django/Flask
go.mod          → Go
Cargo.toml      → Rust
Gemfile         → Ruby/Rails

明确说明你发现了什么:

STACK DETECTED:
- React 19.1.0 (from package.json)
- Vite 6.2.0
- Tailwind CSS 4.0.3
→ Fetching official docs for the relevant patterns.

如果版本缺失或有歧义,询问用户。不要猜,版本决定哪些模式是正确的。

第 2 步:获取官方文档

获取你正在实现的功能对应的具体文档页。不是主页,也不是整套文档,而是相关页面。

来源层级(按权威性排序):

优先级 来源 示例
1 官方文档 react.dev, docs.djangoproject.com, symfony.com/doc
2 官方博客 / changelog react.dev/blog, nextjs.org/blog
3 Web 标准参考 MDN, web.dev, html.spec.whatwg.org
4 浏览器/运行时兼容性 caniuse.com, node.green

不具权威性:绝不要作为主要来源引用:

  • Stack Overflow 答案
  • 博客文章或教程(即使很流行)
  • AI 生成的文档或摘要
  • 你自己的训练数据(这正是重点:要验证)

精确获取所需内容:

BAD:  Fetch the React homepage
GOOD: Fetch react.dev/reference/react/useActionState

BAD:  Search "django authentication best practices"
GOOD: Fetch docs.djangoproject.com/en/6.0/topics/auth/

获取后,提取关键模式,并记录任何废弃警告或迁移指导。

当官方来源彼此冲突时(例如迁移指南与 API reference 矛盾),把差异呈现给用户,并根据检测到的版本验证哪个模式实际可用。

第 3 步:按文档模式实现

编写与文档展示一致的代码:

  • 使用文档中的 API 签名,而不是凭记忆
  • 如果文档展示了新的做法,使用新的做法
  • 如果文档废弃了某个模式,不要使用已废弃版本
  • 如果文档没有覆盖某个点,将其标记为未验证

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

source-driven-development is a skill published in the GitHub repository vinvcn/addyosmani-agent-skills-zh (30 stars, last pushed 4mo ago), licensed MIT. It adds 52 tokens to every session and 1,956 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
