How to configure DSH: config files, model keys, and profiles

DSHDeepSeek Harnessconfigurationprofilecordis.patch.ymlAPI key

DSH keeps its configuration under $DSH_HOME (default ~/.dsh): profile directories hold plugin dependencies and a cordis.patch.yml, and the model key lives in the Web UI settings. Covers where config lives, how to inspect it (dsh --dump-config), how to change it, and common usage like ports and workspaces.

What is DeepSeek Harness? DSH-Plugin plugin architecture explained

1 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.

How to update DSH-Plugin: npx auto-updates vs source rebuilds

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.
