+Fresh stdio sessions use the process launch directory as `session.header.cwd`, so project-scoped features such as skill discovery and default bash workdir follow the directory where `dsh-stdio-agent` was started. Resumed sessions keep the cwd stored in the persisted session header.

 ## The bin
 
 `dsh-stdio-agent [path-to-cordis.yml]` (default `./cordis.yml`) loads a gitignored `.env` from the cwd (`DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`), then drives the cordis Loader against the config and awaits the whole plugin tree before returning. Run it under `node --expose-internals`: the cordis Loader resolves the config's bare plugin specifiers (`@deepseek-ai/dsh-*`, npm packages) through its internal module loader, which is only active under that flag. The `demo:echo` / `demo:coding` scripts invoke it that way.
