Personal AI agents
DeepSeek Harness
An open-source agent you extend with plugins.
What it does
DeepSeek Harness is DeepSeek's open-source agent, in public preview. It runs as a desktop app or as a web UI started with npx. The page lists everyday work such as organizing files, analyzing data, drafting documents, and making slides, plus coding, research, and background tasks. It is built on the Cordis plugin architecture: you install plugins, or describe one in Creator mode and the agent writes and installs it. Scheduled tasks repeat work on a timetable, and developer tools show each tool call and its timing.
Where it fits
Download the macOS or Windows app, or start the web UI from a terminal. Point it at a workspace, ask for one task, and read the tool calls before you allow more access. Add a plugin only when a repeated job needs it.
Before you commit
The page labels it a preview and says core plugins and APIs are still changing. Agent teams, scheduled tasks, and voice input are marked experimental. The code is MIT licensed. The page does not state a price, so check the DeepSeek API terms for the model you connect. This check did not install the app.
