What is DeepSeek Harness? DSH Plugin plugin architecture explained

28 articles

DeepSeek Harness turns the model adapter, tools, sessions, and the agent loop into DSH plugins, while the dsh launcher only boots a profile and combines them on demand. Grasp everything-is-a-plugin and installing, configuring, or building DSH plugins follows naturally.

DeepSeek Harness FAQ: install, configure, update & troubleshoot DSH Plugin

Who are the DSH Plugin tutorials for? Can absolute beginners learn DSH plugins from scratch?

They are for developers who want to get started with DeepSeek Harness Plugin (DSH plugin) quickly — beginners included: install DeepSeek Harness, add your first DSH plugin, then understand the everything-is-a-plugin architecture in order.

What is the best order to read the DSH Plugin tutorials — concepts first or install first?

Follow the order concept → install → hands-on → advanced: first understand DeepSeek Harness Plugin (DSH) and the everything-is-a-plugin architecture, then install it, run your first DSH plugin, and finally explore advanced usage. Articles in the list are already ordered this way.

What are the ways to install a DSH plugin — npx or building from source?

Three common paths: npx fetches the official package temporarily (zero config; uninstall by removing ~/.dsh), building from a source clone suits debugging and development, and dsh plugin add installs plugins into a specific profile. Choose npx to try it fast, or source builds for long-term use; see the install category for details.

Will my DSH plugins break after a DeepSeek Harness update, and how do I avoid it?

Possibly. DeepSeek Harness (DSH) is in developer preview with breaking changes — check each DSH plugin's compatible version and back up session data under ~/.dsh/sessions before upgrading, then re-run your main flows. See the update category for details.

How do I start developing my own DSH plugin?

Start by understanding how DSH plugins relate to profiles: plugins are installed into a profile where pnpm manages dependencies, and dsh plugin forwards commands to that pnpm. Clone the official deepseek-harness repo for reference and debug in an isolated profile (e.g. --profile dev). See the development category.

Can I troubleshoot DeepSeek Harness myself, and is there a recommended order?

Yes — follow three steps: decide whether the error is at startup, plugin, or model stage; confirm the merged config with dsh --dump-config; then address the symptom — use --port for port conflicts, check allowBuilds when plugins won't load, verify the API key when models fail. Common fixes live in the troubleshooting category.

How do the DSH Plugin tutorials relate to the plugin hub? Can I install plugins directly from a tutorial?

The hub lists installable DSH plugins, while tutorials explain how to install, use, and understand DeepSeek Harness Plugin. They interlink: tutorials point to the hub, and plugin detail pages link back to matching tutorials. Always install based on the hub listing.

Why do the commands in the DSH Plugin tutorials keep changing? What if updates land too fast?

DeepSeek Harness Plugin (DSH) is in developer preview, so interfaces and commands can change with breaking updates — which is why tutorial commands change too. This site revises articles alongside official changes and marks each review date as Updated; prefer recently updated articles.

Do the DSH Plugin commands in the tutorials work on macOS, Windows, and Linux?

Most commands are cross-platform, but parts involving paths, package managers, or permissions can differ by system; the tutorials call these differences out explicitly. If an error appears, check the notes for your platform first.

How do I report an error or outdated content in the DSH Plugin tutorials?

DeepSeek Harness Plugin (DSH) is evolving quickly, so tutorials can fall behind the latest release. If you spot an error or outdated content, report it via GitHub Issues; once verified, we revise the article and refresh its Updated date.
