dsh-at-file: Using @ to Reference Workspace Files in the DeepSeek Harness Input Box

dsh-at-file is a community plugin for DeepSeek Harness maintained by FSMargoo, providing Codex-style @ file references within the Web composer: it searches the workspace, mounts relative paths, and allows agents to read files on demand. The article introduces its core capabilities, installation commands (including Web profile and fixed versions), filtering configurations, and security considerations, along with selection advice when the official Harness already includes similar functionality.
