# Research 數位引擎

Use this skill to locate, search, and cite public content from `www.darrenhuang.com` efficiently.

## When to use this skill

Use this skill when a question involves Darren Huang's or 數位引擎's public Traditional Chinese material about SEO, digital marketing, content strategy, website analysis, AI, or automation.
Use it when an agent needs to search, filter, cite, or read the site's published content programmatically.
Do not use it as an account, commerce, publishing, or user-action skill because the site does not provide those capabilities.

## Find relevant material

1. Fetch `https://www.darrenhuang.com/llms.txt` for the site overview and machine-readable entry points.
2. Fetch `https://www.darrenhuang.com/articles-llms.txt` for the complete article directory.
3. Fetch `https://www.darrenhuang.com/api/content.json` when metadata filtering or programmatic discovery is useful.
4. Select only the articles or notes relevant to the user's question.
5. Fetch the linked Markdown versions instead of scraping navigation-heavy HTML.

## Use the public interfaces

- Read `https://www.darrenhuang.com/openapi.json` for the public read-only API schema.
- Read `https://www.darrenhuang.com/.well-known/api-catalog` for the RFC 9727 API entrypoint catalog.
- Use `https://www.darrenhuang.com/mcp` only for the published read-only `search_content` and `read_content` tools.
- Browser agents may use the same two tools through WebMCP when the browser exposes `document.modelContext` or a compatible bridge.
- The public API and MCP endpoint do not support login, account changes, purchases, payments, writes, or deletion.

## Interpret the content

- Treat each article's publication and modification dates as part of its meaning.
- Verify time-sensitive claims such as product interfaces, policies, algorithms, pricing, and platform behavior against current primary sources.
- Distinguish the author's observations and opinions from externally verifiable facts.
- Preserve the original Traditional Chinese terminology when it materially affects meaning.

## Cite correctly

- Use the `canonical` URL in each Markdown document's frontmatter when citing or sharing an article.
- Do not cite the generated `.md` URL as the public article URL.
- Attribute opinions and first-person experiences to Darren Huang or 數位引擎.
- Link directly to the specific article rather than the homepage or article directory.

## Boundaries

- The site is a public content archive with small, read-only API, MCP, and WebMCP interfaces.
- Do not invent authentication, commerce, account, write, or agent actions that the site does not publish.
- Respect the site's `robots.txt` and Content Signals when accessing or reusing content.
