+# search-hub-agents
+
+Search for Agents on the OpenAkita Platform Agent Store.
+
+## When to Use
+
+- User wants to find or browse Agents on the OpenAkita marketplace
+- User asks "有什么 Agent 可以用" or "搜索一个 XX Agent"
+- User wants to discover community-shared Agents by category
+
+## Workflow
+
+1. Call `search_hub_agents` with optional filters
+2. Review results — note the `id` field for each Agent
+3. Use `get_hub_agent_detail` (from install-hub-agent) to inspect before installing
+4. Use `install_hub_agent` to install the chosen Agent
+
+## Parameters
+
+| Parameter | Required | Description |
+|-----------|----------|-------------|
+| `query` | No | Search keyword (e.g. "客服", "project manager") |
+| `category` | No | Filter: customer_service, development, business, creative, education, productivity, general |
+| `sort` | No | Sort by: downloads (default), rating, newest |
+| `page` | No | Page number (default 1, 20 results per page) |
+
+## Fallback
+
+If the remote Agent Store is unavailable:
+- Local Agent import/export via `.akita-agent` files still works
+- Use `list_exportable_agents` to see local Agents
+- Suggest user retry later or check network
