npx create-cordis-plugin my-dsh-pluginCordis Plugins & Ecosystem FAQ
Frequently asked questions about DeepSeek Harness plugin architecture, installation, sandbox safety, and custom development.
What is the DeepSeek Harness plugin system, and how does it differ from traditional agent tools?
Built on the Cordis microkernel, Harness plugins decouple tools, sandboxes, and state machines, enabling models to invoke tools via the bus or write programmatic TypeScript scripts (PTC) to batch-orchestrate workflows.
How do I install and activate a specific Cordis plugin in my project?
You can install plugins with 'npx @deepseek-ai/dsh add [package-name]' or declare the package and configuration directly in 'cordis.yml'. Harness supports live Hot Module Reloading (HMR), applying new plugins without restarting the host agent daemon.
How is runtime safety guaranteed when executing agent plugins?
Harness enforces multi-layered sandbox isolation. High-risk shell commands and builds run inside disposable Docker containers or WebAssembly environments with strict CPU, RAM, and read-only filesystem limits. AST static code scanning and security interceptors are also provided.
How can I integrate existing community MCP tools into Harness?
Harness includes a built-in MCP bridge plugin. Simply configure the MCP server launch command or SSE endpoint in 'cordis.yml'. Harness automatically performs JSON-RPC handshakes, discovers tools, and mounts them as native Cordis services.
How can developers build and publish custom Cordis plugins?
Run 'npx create-cordis-plugin my-plugin' to scaffold a TypeScript project. Implement the standard 'apply(ctx, config)' lifecycle function, publish to npm or GitHub, and leverage TypeScript declaration merging for full intellisense.
How does Harness handle plugin errors, exceptions, or timeouts?
Harness relies on a deterministic state machine and Fiber lifecycle controller. If a plugin throws an exception or times out, error interceptors trap the failure, execute self-healing rollbacks, and inject sanitized error logs into the next reasoning step without crashing the agent process.
