Guides
Learn DeepSeek Harness from the ground up — what it is, how to install and run it, how it works under the hood, and how to extend it with plugins. All guides are grounded in the official docs (verified 2026-08-13).
What is DeepSeek Harness?
Agent = model + harness. Understand dsh — an open-source agent runtime where everything is a plugin.
Installation
Install dsh locally and start the Web UI — one command, then configure a model and run your first task.
Troubleshooting
Port conflicts, profile errors, Windows quirks, and config debugging — with copyable fixes.
Upgrade Guide
Safe path across preview releases — backup, inspect config, upgrade, verify plugins, roll back.
Architecture
Cordis, profiles and bundles, core packages, events, the turn flow, and capability seams.
Plugin Development
End-to-end tutorial: from a minimal local plugin to a published npm bundle.
