🖥 Desktop Client

Introducing the CowAgent Desktop client for macOS and Windows — your local super AI assistant, truly ready to use out of the box.

Download: CowAgent Desktop

Highlights:

• Out of the box: the full Agent runtime is bundled — launch right after install, no need to set up Python or other dependencies
• Full chat experience: streaming replies, session management, tool-call step display, Markdown rendering, plus sending and previewing images / videos / files
• Visual management: configuration, models, knowledge base, scheduled tasks, skills, and memory pages mirror the Web console, all manageable in the native UI
• Channel onboarding: connect messaging channels by scanning a QR code right inside the app
• Auto update: automatic version checks and one-click updates, with download speed optimized across regions
• Native experience: first-run onboarding, follows the system language, and platform-adaptive window interactions

📚 Knowledge Base

• Create & import documents: create new documents or import external ones directly from the UI
• Automatic index maintenance: the knowledge base index is rebuilt automatically from the actual directory tree, preventing index drift or lost documents
• Vectorization fix: the index now reuses the unified embedding provider, ensuring real semantic vectors instead of falling back to keyword search

Thanks @yangziyu-hhh

🔌 On-demand MCP Tool Retrieval

To address context bloat when many MCP tools are connected, we added on-demand tool retrieval: relevant MCP tools are loaded on demand via RAG vector search based on the current task, reducing the context taken up by irrelevant tools.

Thanks @fengyl07

🌏 Traditional Chinese Support

The Web console, logs, and documentation now support Traditional Chinese (zh-Hant); the interface language can follow the system or be switched manually.

🔒 Security Hardening

• More reliable file editing: better preserves original indentation, and fuzzy matching no longer touches unrelated content. Thanks @weijun-xia (#2942)
• Command output encoding fix: fixed garbled Chinese characters when a command produces large output. Thanks @weijun-xia (#2941)
• Azure OpenAI fixes: fixed streaming output and related configuration issues for Azure OpenAI. Thanks @Tunnello
