Copilot

devantler-tech/agent-plugins

A tool-neutral agent-plugin marketplace that bundles curated agent skills — sourced from across the agent-skill ecosystem — into category-based plugins.

Supports VS Code, GitHub Copilot CLI, and Claude Code via dual marketplace manifests.

Scope

This is a tool-neutral plugin marketplace, not a skills-only bundler. Every plugin published today bundles agent skills, but a plugin may bundle any agent resource — skills, MCP servers, and custom agents — so the marketplace can grow with the cross-tool agent ecosystem instead of being pinned to one tool or one resource type. Additional resource types are added as they prove out across the supported tools.

Plugins

gitops-kubernetes	gitops-cluster-debug, gitops-knowledge, gitops-repo-audit, gitops-tenant-onboarding	Flux CD debugging, knowledge, repository auditing, and tenant onboarding

Installation

VS Code

Add the marketplace to your settings:

// settings.json
"chat.plugins.marketplaces": [
    "devantler-tech/agent-plugins"
]

Then browse Extensions → Agent Plugins (@agentPlugins search) to install individual plugins.

Copilot CLI

# Browse available plugins
copilot plugin marketplace browse devantler-tech/agent-plugins

# Install a plugin
copilot plugin install gitops-kubernetes@devantler-plugins

Claude Code

Add the marketplace, then install a plugin — run these inside Claude Code:

/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.

How it works

Skills are installed from their upstream repositories using gh skill install. A daily update workflow runs gh skill update --all via the update-agent-skills reusable workflow and opens a PR when upstream content has drifted.

Each plugin directory is self-contained with a plugin.json manifest and a skills/ subdirectory holding the installed SKILL.md files (plus any supporting assets). Each SKILL.md contains metadata.github-* frontmatter for upstream provenance — no lockfile needed.

Each bundled skill is pulled from its own upstream (recorded in its SKILL.md metadata.github-* frontmatter), spanning many sources — including our in-house sibling library devantler-tech/agent-skills.
