DeepSeek Harness Desktop Preview v0.2 Released with Plugin Support and Automation
DeepSeek has released the desktop preview v0.2 of DeepSeek Harness for macOS and Windows, featuring GUI-based plugin installation via npm package names, scheduled automated tasks, and enhanced code and document previews. It also introduces an experimental "Creation Mode" that allows users to generate and edit custom plugins using natural language prompts. This update significantly lowers the entry barrier for using AI developer agents by turning CLI-based plugin setup into a visual desktop workflow. It demonstrates DeepSeek's push toward building a modular agent ecosystem where tools and automation can be effortlessly extended by users. The release allows users to inspect code diffs and files directly in the sidebar, manage execution steps for transparency, and set up recurring task schedules. DeepSeek reported that around 60% of its API users currently utilize third-party plugins, prompting future plans for an official plugin marketplace, long-term memory support, and GUI automation.
## BACKGROUND
DeepSeek Harness is an open-source AI agent framework developed by DeepSeek AI, designed around an "everything-is-a-plugin" architecture powered by Cordis. An AI agent harness serves as the execution runtime connecting large language models (LLMs) to local files, system tools, memory, and scheduled loops to execute complex multi-step workflows.
