DeepSeek Harness: FREE 1 Hour Course!

Deepseek Harness Full Course: Free AI Employee, Custom Plugins & Agentic Operating SystemsThis course walks through Deepseek's brand new open-source AI harness, released August 13th as an MIT-licensed alternative to Claude Code and Codex. It covers installing the tool in under five minutes, connecting a free brain via OpenRouter or OpenCode, and setting up a clean workspace for real tasks. It then explores the "everything is a plugin" architecture, including Creator Mode for building custom tools by simply describing them, the trajectory view for full transparency into every agent action, and how MCP and agents.md files let it share context with other agents. It closes by building a full agentic operating system with Obsidian as shared memory, running multiple agents in parallel, and plugging free models directly into the dashboard.
