What

Turn AI from "Random Guessing" to "Precise Querying"

AI models don't understand WeCom API details by default. SKILLs give them precise knowledge of every endpoint's real constraints.

Without SKILL

Build me an auto welcome message feature

Sure, let me write that…

// ❌ Fabricates API from memory
// ❌ Misses WelcomeCode 20s expiry
// ❌ Confuses follow_user vs follow_info

With SKILL

Build me an auto welcome message feature

Loaded wecom-crm-customer, note:

Listen for add_half_external_contact callback
WelcomeCode valid for only 20 seconds
First GET /externalcontact/get to fetch channel

Why

Core Value

Not just a documentation mirror, but knowledge engineering deeply optimized for AI

Precise API Knowledge

Every endpoint with exact parameters, response structures, and constraints

Endpoint-level precisionTraceable doc_idComplete param types

Gotcha Guide

Real-world pitfalls, field ambiguities, and time-sensitive constraints

Real-World Comparison

Same dev request — the quality gap between AI with and without SKILLs is crystal clear

Dimension	Without SKILL	With SKILL
API Path	May fabricate non-existent endpoints	Precise to /externalcontact/resigned/transfer_customer
Field Ambiguity	Unaware of follow_user vs follow_info difference	Proactively flags as CRITICAL gotcha
Transfer Types	Confuses on-job and resigned transfer	Provides 6-dimension comparison table
Chat Archive	May fabricate HTTP API	Clearly states C/C++ SDK required
Error Handling	Thinks errcode=0 means all success	Reminds to check each customer[].errcode
