**The zhangxuefeng‑skill repository stores its skill definitions entirely in Markdown files enriched with YAML front‑matter headers, following the Agent Skills specification.**

The `alchaincyf/zhangxuefeng-skill` project implements a conversational AI persona using a structured data format that combines machine-readable metadata with human-readable documentation. This approach leverages the **Agent Skills** protocol, allowing the skill to be installed and interpreted by compatible runtimes like Claude Code, Codex, and Cursor.

## The Core Data Format: Markdown with YAML Front‑Matter

At the heart of the repository lies [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md), which exemplifies the primary data format. The file begins with a **YAML front‑matter block** delimited by triple dashes, followed by standard Markdown content.

The YAML header defines the skill's identity:

```yaml
---
name: zhangxuefeng-perspective
description: |
  张雪峰的思维框架与表达方式。基于5本著作、15+篇权威媒体深度采访、...
---

```

Everything following the closing `---` delimiter is **plain Markdown** that encodes the actual skill behavior. This includes role‑play rules, workflow definitions, mental models, and decision heuristics.

```markdown

## 角色扮演规则（最重要）

- 用「我」而非「张雪峰会认为...」
- 直接用东北大哥的语气、快节奏、段子化的方式回答问题
...

```

## Repository File Organization

The project maintains a consistent format across all documentation and resource files.

### SKILL.md

Located at the repository root, [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md) serves as the canonical skill definition. It combines the YAML metadata header with the operational Markdown body that defines the Zhang Xuefeng persona implementation.

### README.md

The [`README.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/README.md) file provides repository overview, installation instructions, and Agent Skills protocol badges. It references the primary [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md) file and explains how the YAML front‑matter enables runtime discovery.

### Auxiliary Resources

All supporting materials use the same **plain Markdown** format:

- **references/research/01-writings.md**: Research summaries stored as Markdown documents
- **examples/demo-conversation.md**: Sample dialogues demonstrating the skill in action

This uniformity ensures that content parsers can process the entire repository using a single Markdown parser without format switching.

## Agent Skills Protocol Integration

The data format adheres to the **Agent Skills** specification, which mandates that skill definitions reside in `*.md` files with YAML front‑matter. This standardization enables one‑command installation:

```bash
npx skills add alchaincyf/zhangxuefeng-skill

```

The installer reads the YAML front‑matter in [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md) to identify the skill's name (`zhangxuefeng-perspective`) and description before registering it with the local development environment.

## Summary

- **zhangxuefeng-skill** uses **Markdown with YAML front‑matter** as its exclusive data format.
- The [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md) file contains a YAML header defining metadata (`name`, `description`) followed by Markdown content defining behavior.
- Auxiliary files in `references/` and `examples/` maintain the same plain Markdown format.
- This structure complies with the **Agent Skills** protocol, enabling installation via `npx skills add`.

## Frequently Asked Questions

### What file extension does zhangxuefeng-skill use?

The repository uses `.md` (Markdown) extensions for all content files. The primary definition resides in [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md), while documentation and examples use the same extension, ensuring compatibility with standard Markdown parsers.

### How is the YAML front-matter structured in SKILL.md?

The YAML block appears at the very beginning of [`SKILL.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/SKILL.md), enclosed between triple-dash delimiters (`---`). It defines two key fields: `name` (set to `zhangxuefeng-perspective`) and `description` (a multi‑line string explaining the persona's cognitive framework and expression style).

### Can zhangxuefeng-skill be consumed by any AI assistant?

Yes. Any runtime implementing the **Agent Skills** protocol—including Claude Code, Codex, Cursor, OpenClaw, and Hermes Agent—can interpret the YAML front‑matter and Markdown body to instantiate the Zhang Xuefeng persona.

### Where are the research sources stored?

Research materials reside in the `references/` directory as plain Markdown files. For example, [`references/research/01-writings.md`](https://github.com/alchaincyf/zhangxuefeng-skill/blob/main/references/research/01-writings.md) contains synthesized research content that supports the skill's knowledge base, all formatted as standard Markdown without YAML headers.
