"""OpenClaw Skill for AgentEvalTool — HTTP API mode.

Triggers an evaluation run via the AgentEvalTool REST API, polls until
completion, and returns a structured Chinese-language summary suitable for
display in an OpenClaw conversation.

Configuration (passed via OpenClaw skill params):
    api_base_url    Base URL of AgentEvalTool (e.g. http://192.168.8.145:8001)
    api_key         X-API-Key header value (if auth is enabled, else omit)
    target_id       ID of the registered evaluation target
    scenario_id     ID of the evaluation scenario
    poll_interval   Seconds between status polls (default: 3)
    timeout         Max seconds to wait for completion (default: 300)
