SpecFusion — Search 15 Chinese open platform API docs directly in Claude Code

[wxkingstar]

Hey everyone! I built a Claude Code skill called SpecFusion that lets you search API docs from 15 Chinese open platforms without leaving your terminal.

The Problem

If you work with Chinese platform APIs (WeChat Work, Feishu/Lark, DingTalk, Taobao, etc.), you know the pain — each platform has its own doc site, and you spend half your time switching between browser and editor looking up endpoints and parameters. Claude's training data doesn't fully cover these platforms, so it often "hallucinates" API parameters.

The Solution

SpecFusion indexes 26,840+ API docs from 15 platforms with jieba Chinese tokenization + SQLite FTS5 full-text search. Install with one command, and Claude Code can search the real docs in real-time:

npx skills add wxkingstar/SpecFusion -g -y

Then just ask naturally:

• "How do I send a WeChat Work application message?"
• "What's the Feishu approval instance creation API?"
• "How to query Douyin e-commerce order list?"

Supported Platforms (15)

WeChat Work (~2,680 docs) · Feishu/Lark (~4,070) · DingTalk (~2,020) · Taobao (~6,740) · Xiaohongshu (~100) · Douyin E-commerce (~1,280) · WeChat Mini Program (~280) · WeChat Shop (~480) · Pinduoduo (~280) · Youzan (~1,240) · WeChat Pay (~540) · Alipay (~600) · JD (~6,100) · SHEIN (~190) · Dewu (~260)

Key Features

• Chinese FTS: jieba tokenization + FTS5 — accurate search in both Chinese and English
• Zero config: Cloud-hosted, works immediately after install
• Multi-tool: Works with Claude Code, Cursor, Gemini CLI, Codex CLI
• Open source & self-hostable: Docker support for private deployment

Would love feedback from anyone working with Chinese platform APIs! ⭐
