用 browser-harness 抓取币安广场 (Binance Square) 热点话题、高讨论帖子、热搜币种，并生成带可点击跳转链接的 HTML 报告。
Direct browser control via CDP. Use when the user wants to automate, scrape, test, or interact with web pages. Connects to the user's already-running Chrome.
Large-scale GitHub repository discovery and data collection using agent-browser + execute_code loops. Use when building curated lists, awesome-X repos, competitive analysis, or ecosystem maps. Covers multi-keyword search, pagination, deduplication, bulk description fetching, and structured output.
Create Hermes plugins that hook into the agent lifecycle (post_llm_call, pre_tool_call, on_session_end, etc.). Covers plugin structure, available hooks, and macOS notification pattern.
