dsh-plugin-switch

A marketplace for community DeepSeek Harness plugins. The plugin adds a Marketplace tab inside Settings → Plugins, browses the official dsh-plugin GitHub topic, and installs chosen repositories through dsh plugin add.

Before installing, Marketplace reads the repository's Git tree. Repositories with cordis.patch.yml are installed as profile plugins. Repositories with a root SKILL.md, .dsh/skills//SKILL.md, or .agents/skills//SKILL.md are installed as DSH skills under ~/.dsh/skills//; no package lifecycle scripts run for this path.

Status

This iteration ships both halves:

• Host (src/index.ts) — talks to GitHub REST, caches the search for ten minutes, reads each repo's optional plugin.json, and spawns dsh plugin add as a child process for installs. Exposes ctx.marketplace for the client.
• Client (src/client/) — registers a tab into the official settings.plugins.tab slot , renders the search box + repo list + install buttons, and calls the host service through the cordis DI proxy.

Why host + client

DSH plugins are roles in capability seams . This plugin needs both roles:
