Technical Writing
使用范围与安全规则
本 Skill 只用于“技术文档专业写作”场景，围绕用户当前提供或明确授权处理的材料完成任务。功能目标：生成API参考、用户指南、入门教程、变更日志等专业技术文档，分析目标受众结构化信息层级。
- 默认先在回复中交付分析、方案、草稿、代码建议或检查清单，不主动读取任务范围外的文件、账号和数据。
- 信息不足时先标记缺口并向用户确认，不用猜测内容填补事实、数字、姓名、结论或权限。
- 需要联网检索或调用接口时，先说明访问目标、拟发送的数据和用途并取得用户明确同意；只访问用户指定或公开合法来源，不绕过登录、付费墙、验证码、访问控制或平台限制。
- 涉及发送、发布、上传、删除、支付、投放、部署、同步或其他外部写入时，先展示目标、内容和影响，获得用户对该次动作的明确确认后再执行。
- 不要求用户在对话里粘贴密码、Cookie、Token、API Key 或私钥；凭据仅用于用户指定的对应官方服务，不回显、不记录、不写入交付物，也不转发到无关地址。
- 命令和脚本默认作为可审查的参考方案；只有用户明确要求执行、目标路径与影响范围清楚且完成预检后，才运行必要的最小步骤。
- 交付前复核事实依据、隐私、版权、平台规则和可执行边界；发现高风险或越权请求时停止相关动作，并给出合规替代方案。
This skill enables an AI agent to produce high-quality technical documentation across a range of formats — API references, user guides, getting-started tutorials, changelogs, architecture decision records, and more. The agent analyzes the target audience, structures information logically, applies consistent formatting standards, and ensures every document is accurate, scannable, and actionable.
Workflow
-
Identify Document Type and Audience
Determine which type of document is needed (API reference, tutorial, user guide, changelog, architecture doc) and who will read it (beginner developers, experienced engineers, end users, stakeholders). Adjust vocabulary, depth, and assumed prerequisites accordingly. A tutorial for beginners should explain every step; an API reference for senior engineers should be terse and precise. -
Gather Source Material
Collect all relevant inputs: source code, existing documentation, design documents, user stories, API schemas (OpenAPI/Swagger), commit histories, or stakeholder interviews. Identify the authoritative source for each piece of information to ensure accuracy. Note any gaps that need clarification. -
Design the Document Structure
Create an outline following the conventions of the document type. API references use a consistent per-endpoint template. Tutorials follow a step-by-step progression. Architecture docs follow a decision-record format (context, decision, consequences). Plan where code examples, tables, and callout boxes will appear. -
Write the Content
Draft the document using clear, direct language. Prefer active voice and short sentences. Lead each section with the most important information. Include complete, runnable code examples that readers can copy and execute. Use consistent terminology and define acronyms on first use. Format according to the chosen standard (Markdown, reStructuredText, AsciiDoc). -
Add Navigation and Cross-References
Insert a table of contents for long documents, anchor links between related sections, and links to prerequisite or follow-up documentation. Add "Next steps" sections at the end of tutorials. -
Review for Accuracy and Completeness
Verify all code examples compile or run correctly. Confirm API endpoint paths, parameters, and response schemas match the actual implementation. Check that every tutorial step produces the described result. No placeholder text or TODO items should remain.
Usage
Provide the agent with:
- Document type — API reference, tutorial, user guide, changelog, architecture decision record, README
- Subject — the feature, API, tool, or system to document
- Audience — skill level and role of the intended readers
- Source material — code files, schemas, design docs, or a description of the feature
- Format — Markdown, reStructuredText, AsciiDoc, or HTML
Example prompt: "Write an API reference for the /users endpoint. The audience is third-party developers. Here is the OpenAPI spec: [attached file]."
Examples
Example 1: API Endpoint Reference
Input: "Document the POST /api/v1/webhooks endpoint. Creates a webhook subscription. Requires Bearer token auth. Body: url (string, required), events (string[], required), secret (string, optional). Returns 201 or 422."
Output:
> ## POST /api/v1/webhooks
>
> Creates a new webhook subscription. Requires a Bearer token in the Authorization header.
>
> | Field | Type | Required | Description |
> |-------|------|----------|-------------|
> | url | string | Yes | HTTPS endpoint URL to receive payloads. |
> | events | string[] | Yes | Event types to subscribe to (e.g., ["order.created"]). |
> | secret | string | No | HMAC-SHA256 signing secret. Auto-generated if omitted. |
>
> bash
> curl -X POST https://api.example.com/api/v1/webhooks \
> -H "Authorization: <user-provided-token> \
> -H "Content-Type: application/json" \
> -d '{"url":"https://myapp.com/hooks","events":["order.created"]}'
>
>
> 201 Created: {"id":"wh_9a8b7c6d","url":"https://myapp.com/hooks","events":["order.created"],"active":true}
>
> 422 Error: {"error":{"code":"validation_error","details":[{"field":"url","message":"URL must use HTTPS."}]}}
Example 2: Getting-Started Tutorial
Input: "Write a getting-started tutorial for our Python SDK (acme-sdk). Install, authenticate, and list projects."
Output:
> # Getting Started with the Acme Python SDK
>
> ## Prerequisites
> - Python 3.9+ and an Acme API key (found at Settings > API Keys)
>
> ## Step 1: Install the SDK
> bash
> pip install acme-sdk
>
>
> ## Step 2: Set Your API Key
> bash
> export ACME_API_KEY="sk_live_your_key_here"
>
>
> ## Step 3: List Your Projects
> python
> import os
> from acme_sdk import AcmeClient
>
> client = AcmeClient(api_key=os.environ["ACME_API_KEY"])
> for project in client.projects.list():
> print(f"{project.id}: {project.name}")
>
>
> Expected output:
> > proj_abc123: My First Project
> proj_def456: Marketing Site
>
>
> ## Next Steps
> - Create a project programmatically
> - Set up webhooks for real-time events
Best Practices
- Lead with the action. Start each section with what the reader needs to do, not background context. Put explanations after the instruction.
- Provide complete, runnable code. Every code example should work as-is when copied. Include imports, variable declarations, and expected output.
- Use consistent templates. API references should follow the same structure for every endpoint. Tutorials should follow the same step format throughout.
- Write scannable content. Use headings, tables, bullet points, and code blocks so readers can find information quickly without reading every paragraph.
- Version your documentation. Tie docs to specific software versions. Clearly indicate which version introduced a feature or deprecated an API.
- Test your instructions. Walk through every step in a tutorial to confirm it produces the described result.
Edge Cases
- Undocumented behavior: If source code reveals behavior not described in any spec, document it as "current behavior" and flag it for the engineering team to confirm as intentional.
- Multiple audiences for one document: Use a layered approach — put essentials first with expandable "Advanced" sections or links to deeper docs.
- Rapidly changing APIs: Note the version or date prominently and include a disclaimer that the interface may change.
- Missing source material: Explicitly list what information is missing and request it rather than guessing.
- Non-English documentation: Follow the technical writing conventions of that language's developer community rather than translating English conventions literally.
