Add the marketplace to your settings:
Then open Extensions, search @agentPlugins, and install a plugin from this marketplace. Review the source when VS Code asks you to trust it. See the VS Code plugin guide.
Run these in your terminal; devantler-plugins is the marketplace name registered by the first command. See the Copilot plugin reference.
# Register the marketplace
copilot plugin marketplace add devantler-tech/agent-plugins
# Browse available plugins
copilot plugin marketplace browse devantler-plugins
# Install a plugin
copilot plugin install gitops-kubernetes@devantler-pluginsAdd the marketplace, then install a plugin — run these inside Claude Code (official guide):
/plugin marketplace add devantler-tech/agent-plugins
/plugin install gitops-kubernetes@devantler-plugins
Browse everything on offer with /plugin (Discover tab) or list it with /plugin list. The bundled .claude-plugin/marketplace.json is also discovered automatically when this repo is added as a plugin source.
Claude Desktop can add the same GitHub repository from Plugins → Personal. That path validates the marketplace remotely in strict mode; every plugin therefore includes the canonical .claude-plugin/plugin.json manifest it requires.
npx skills reads this repo's .claude-plugin/marketplace.json and installs the bundled skills into its supported agents — useful when your agent isn't one of the three above:
# Browse the bundled skills without installing
npx skills add devantler-tech/agent-plugins --list
# Install specific skills for a specific agent
npx skills add devantler-tech/agent-plugins --skill gitops-knowledge --agent cursorImportant
This is a partial install path. The example installs only gitops-knowledge for Cursor. Use
--all to install every bundled skill across detected agents, or choose another skill by name
with --skill <name> and --agent cursor to target that agent. None of these skills-only forms
install the MCP servers or custom agents. To get everything a
plugin bundles, install it as a plugin in VS Code, Copilot CLI, or Claude Code above —
all three load a plugin's bundled .mcp.json and agents/ automatically.
