Extend a running agent with Cordis tools

English | 中文

This practice guide enables @deepseek-ai/dsh-tool-cordis. The agent can inspect its current Cordis process and mount or unmount model-authored plugins in memory. Temporary plugins disappear when they are unmounted or the process exits and may affect other sessions in the same process.

Run it

Start the browser interface with the checked-in overlay:

pnpm dsh web --patch apps/cli/config/examples/cordis/cordis.yml

The command requires a model credential. The Cordis tool reference defines the tool arguments, lifetime, cleanup, and safety contracts.
