# HackerNews数据服务
一个通过Model Context Protocol提供HackerNews内容搜索、检索和分析的服务，适用于AI代理和开发者。
---
## ⚠️ 强制要求：API 密钥
**此 Skill 必须配置 API 密钥才能使用。**
- 首次使用时，如果 `.env` 中没有 `XBY_APIKEY`，**必须使用 AskUserQuestion 工具向用户询问 API 密钥**
- 拿到用户提供的密钥后，调用 `scripts.config.set_api_key(api_key)` 保存，然后继续处理
- 获取 API 密钥：https://xiaobenyang.com
- **禁止**在缺少 API 密钥时自行搜索或编造数据
---
## 工作流程（必须遵守）
你（大模型）是路由层，负责理解用户意图、选择工具、提取参数。代码只负责调用API。
```
用户输入 → 你选择工具 → 提取该工具需要的参数 → 调用 scripts.tools 中的函数 → 返回结果给用户
```
### 步骤
1. **检查 API 密钥**：如果 `scripts.config.settings.api_key` 为空，使用 AskUserQuestion 询问用户，拿到后调用 `scripts.config.set_api_key(key)` 保存
2. **选择工具**：根据用户意图从下方工具列表中选择对应的工具函数
3. **提取参数**：根据选中的工具，提取该工具需要的参数
4. **调用工具**：使用**关键字参数**调用 `scripts.tools` 中的函数，例如 `scripts.tools.search_schools(score='520', province='北京', category='综合')`
5. **返回结果**：将工具返回的 `raw` 数据整理后展示给用户

## 工具选择规则
根据用户意图选择对应的工具函数：
| 用户意图 | 工具函数 |
|---------|---------|
| Search HackerNews for stories, comments, and other content by keyword.
Supports:
- Keyword search across titles, text, and authors
- Tag filtering (story, comment, poll, show_hn, ask_hn, front_page, author_USERNAME)
- Numeric filters for points, comments, and dates
- Pagination with customizable results per page
- Advanced filtering with OR logic and multiple conditions
Basic Examples:
- Search for AI stories: { "query": "AI", "tags": ["story"] }
- Find popular posts: { "query": "Python", "numericFilters": ["points>=100"] }
- Filter by author: { "query": "startup", "tags": ["author_pg"] }
- Date range: { "query": "startup", "numericFilters": ["created_at_i>1640000000"] }
Advanced Filtering Examples:
- High engagement posts: { "query": "programming", "numericFilters": ["points>=100", "num_comments>=50"] }
- OR logic for tags: { "query": "web", "tags": ["(story,poll)"] } - returns stories OR polls
- Author with filters: { "query": "", "tags": ["author_pg", "story"], "numericFilters": ["points>=50"] }
- Multiple conditions: { "query": "AI", "tags": ["story"], "numericFilters": ["points>=200", "num_comments>=100"] }
Numeric Filter Operators: < (less than), <= (less than or equal), = (equal), >= (greater than or equal), > (greater than)
Numeric Filter Fields: points, num_comments, created_at_i (Unix timestamp)
Tag Syntax:
- Single tag: ["story"] - only stories
- Multiple tags (AND): ["story", "show_hn"] - stories that are also show_hn
- OR logic: ["(story,poll)"] - stories OR polls
- Author filter: ["author_USERNAME"] - posts by specific author
Returns paginated results with hits, total count, and page information. | `scripts.tools.search_posts` |
| Retrieve posts currently on the HackerNews front page.
Returns stories sorted by HackerNews ranking algorithm. The front page typically contains the most popular and trending stories.
Supports:
- Pagination to view beyond the first page
- Customizable results per page (default: 30)
- All posts are tagged with 'front_page'
Examples:
- Get first page: { }
- Get with custom page size: { "hitsPerPage": 50 }
- Get second page: { "page": 1 }
Returns the same structure as search results with hits, pagination info, and metadata. | `scripts.tools.get_front_page` |
| Retrieve the most recent HackerNews posts sorted by date.
Returns posts in chronological order (newest first), including all types of content unless filtered.
Supports:
- Filter by content type using tags (story, comment, poll, show_hn, ask_hn, etc.)
- Pagination to view older posts
- Customizable results per page (default: 20)
- Empty query to get all recent posts
Examples:
- Get latest stories: { "tags": ["story"] }
- Get latest comments: { "tags": ["comment"] }
- Get all recent activity: { }
- Get with custom page size: { "hitsPerPage": 50 }
Use this to monitor real-time HackerNews activity or find the newest content. | `scripts.tools.get_latest_posts` |
| Retrieve detailed information about a specific HackerNews item by ID.
Returns complete item details including the full nested comment tree. Use this to:
- View a story with all comments
- Read a specific comment with its replies
- Explore discussion threads in depth
- Get complete metadata for any item
Features:
- Full nested comment tree (all levels)
- Complete item metadata (title, url, text, points, author, etc.)
- Works for stories, comments, polls, and poll options
- Includes creation time and item type
Examples:
- Get story with comments: { "itemId": "38456789" }
- Get specific comment: { "itemId": "38456790" }
- Get poll: { "itemId": "126809" }
Note: Large comment threads (>500 comments) may take 2-3 seconds to load due to nested fetching.
Returns error if item doesn't exist or has been deleted. | `scripts.tools.get_item` |
| Retrieve public profile information for a HackerNews user.
Returns user profile including karma, bio, and account creation date. Use this to:
- Check user reputation (karma score)
- Read user bio and about information
- See when account was created
- Verify user existence before searching their content
Features:
- Username (case-sensitive)
- Karma score (total upvotes received)
- About/bio text (may contain HTML)
- Account creation date (Unix timestamp)
Examples:
- Get famous user: { "username": "pg" }
- Check moderator: { "username": "dang" }
- Verify author: { "username": "tptacek" }
Username validation:
- Alphanumeric characters and underscores only
- Case-sensitive
- Must exist on HackerNews
Returns error if user doesn't exist or username format is invalid. | `scripts.tools.get_user` |
**如果参数不完整，使用 AskUserQuestion 向用户询问缺失的参数。**

## 注意事项
1. **API 密钥是必需的**，无密钥时必须通过 AskUserQuestion 询问用户
2. **禁止**在缺少 API 密钥时自行搜索或编造数据don't have the plugin yet? install it then click "run inline in claude" again.
