WeChat Search Skill

Search for WeChat Official Account (微信公众号) articles using a compliant, three-layer approach that prioritizes legal search APIs and falls back to respectful web scraping when needed.

Features

• Compliant Design: Prioritizes legal search APIs, respects robots.txt and rate limits

• Three-Layer Strategy:

  • Primary: OpenClaw web_search (Brave Search API)
  • Secondary: Tavily Search API (if Brave unavailable)
  • Fallback: Direct page fetching from WeChat search

• Recent Results: Returns the 5 most recent articles by default (configurable)

• Time Filtering: Support for date range and recency filters

• Multiple Output Formats: Text, JSON, and markdown formats available

Prerequisites

• OpenClaw Web Tools: Requires web_search, web_fetch tools to be available

• API Keys (optional but recommended):

  • Brave Search API Key (for primary search)
  • Tavily API Key (for secondary search, already configured in your environment)

Usage

Basic Search

wechat-search "人工智能"

Advanced Options

# Return 10 results instead of default 5
wechat-search "机器学习" --max-results 10

# Search within past week
wechat-search "大模型" --past-week

# Custom date range
wechat-search "AI应用" --from 2026-01-01 --to 2026-02-01

# JSON output format
wechat-search "开源AI" --output json

# Force specific strategy
wechat-search "最新技术" --strategy tavily_only

Configuration

Create ~/.openclaw/wechat-search-config.json to customize behavior:

{
  "defaultMaxResults": 5,
  "maxResultsLimit": 20,
  "requestDelayMs": 5000,
  "cacheDurationHours": 1,
  "userAgent": "OpenClaw-WeChat-Search-Bot/1.0 (+https://github.com/your-username/wechat-search-skill)"
}

Search Strategy Details

Layer 1: OpenClaw Web Search (Brave Search)

• Uses Brave Search API with site:mp.weixin.qq.com filter

• Fastest and most reliable when API key is configured

• Respects search engine's indexing and ranking

Layer 2: Tavily Search API

• Activated when Brave Search is unavailable or fails

• Uses Tavily's AI-powered search with WeChat site restriction

• Provides high-quality, relevant results with good coverage

Layer 3: Direct Web Fetch

• Final fallback when both APIs are unavailable

• Scrapes WeChat search results directly from搜狗微信搜索

• Implements proper delays and respects robots.txt

• Parses HTML to extract article metadata

Compliance & Ethics

• Respects robots.txt: Checks and follows robots.txt directives

• Rate limiting: Minimum 5-second delay between requests

• Transparent identification: Clear User-Agent string identifying the bot

• Public content only: Only accesses publicly available articles

• No data retention: Does not store full article content, only metadata

Error Handling

• Automatic retry on network failures (up to 3 attempts)

• Graceful fallback between all three search strategies

• Clear error messages for debugging

• Handles API key missing scenarios gracefully

Future Enhancements

• RSS feed integration support

• Article content summarization

• Author/subscription management

• Enhanced filtering options

This skill is designed to be both useful and responsible, providing access to valuable WeChat Official Account content while respecting platform rules and legal requirements.
