Install Claude Code plugins in DeepSeek Harness

This guide shows how to bring Claude Code, Codex, Cursor and Kimi plugin marketplaces into DeepSeek Harness (DSH) in a few minutes.

Prerequisites

• DeepSeek Harness ≥ 0.1.0-rc.6 with a Web profile
• A terminal with dsh and pnpm available

Step 1 — Install the plugin

npm registry (recommended):

# inside a dsh profile
pnpm add dsh-agent-plugins-market

# or via the dsh CLI
dsh plugin --profile <name> add dsh-agent-plugins-market

Or install directly from GitHub:

dsh plugin --profile <name> add github:Sivan757/dsh-agent-plugins-market

Step 2 — Restart dsh and open the market

Restart dsh, open the Web GUI, then go to Settings → Agent Plugins Market. The built entry point is committed to the repository, so GitHub installs work without a build step.

Step 3 — Add a marketplace source

In the market page, add any git marketplace repository URL as a source (for example a Claude Code marketplace repo with .claude-plugin/marketplace.json). The source id is derived automatically from the repository manifest — no manual input.

Step 4 — Install suites

Browse the card grid, open a suite for a preview of its skills / MCP servers / hooks / commands, and install it. Installed plugins live under ~/.dsh/agent-plugins/.sources/<sourceId>/ (user dimension) or <project>/.dsh/agent-plugins/.sources/<sourceId>/ (project dimension).

Step 5 — Use it

• Skills appear in the / slash menu; Claude Code-authored skills work verbatim.
• MCP servers mount automatically — tools appear as mcp__<plugin>__<server>__<tool>.
• Hooks from hooks/hooks.json are mapped to DSH interception points.
• Commands / subagents — commands/*.md become slash commands; agents/*.md become agent-<name> skills.

Troubleshooting

• Project-dimension MCP servers are not mounted (DSH has no per-session tool scope); the project dimension covers skills and context.
• Skill discovery has no file watcher — catalog changes apply after a manager action or a host restart.
• Remote URL marketplace entries show as "remote reference" cards; add the target repo as a source to install them.
