Intent Routing Rules (Highest Priority)

When to USE this Skill

• URL ends with /v1/chat/completions (OpenAI-compatible)
• URL ends with /v1/messages (Claude/Anthropic-compatible)
• User mentions "LLM", "大模型", "模型接口", "OpenAI", "Claude", "chat completions"
• curl command body contains "model" and "messages" fields

When NOT to use this Skill

Condition	Use Instead
URL is a webpage (e.g. https://www.baidu.com)	lmeterx-web-loadtest
URL is a regular API without LLM path patterns (e.g. /api/users, /graphql)	lmeterx-http-loadtest
User says "网站/网页/页面"	lmeterx-web-loadtest

Quick Decision Rule

URL ends with /v1/chat/completions or /v1/messages → THIS SKILL
URL is a normal webpage                            → lmeterx-web-loadtest
Everything else (REST API, GraphQL, etc.)          → lmeterx-http-loadtest

Execution Rules

1. Mandatory: You must and may only execute the provided script via Bash.
2. Prohibition: Do NOT manually construct HTTP requests using curl or requests to call LMeterX APIs.
