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。

text

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

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
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
提取参数：根据选中的工具，提取该工具需要的参数
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')
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
