Why AgentSkills CLI?

View on GitHub

First-class NuGet support

Install from public or private NuGet feeds using your existing NuGet.config and credential providers. Azure Artifacts, GitHub Packages, ProGet, MyGet - if `dotnet restore` works against your feed, `agentskills-cli` does too. No new auth surface.

Ship skills inside your library

Drop a skills/ folder into your existing NuGet or npm package and it becomes a skill source automatically. The SDK and the agent guidance for using it travel together, version together, and discover together. Library authors keep doing what they already do.

First-class npm registry fetch

Public and private npm registries via your existing .npmrc - scoped registries, _authToken, longest-path-prefix auth matching. Real registry fetch, not just node_modules sync. No Node runtime needed.

Every coding agent

Claude Code, Cursor, Codex, OpenCode, and any agent that reads the universal .agents/skills directory. Auto-detected; install once, picked up by all of them.

Extension points by design

Register ISkillSourceFactory for new source types (cargo, oci, conda, your internal feed) and ISkillSearchProvider for new search backends (internal registries, GitHub topic search) with a single DI registration. No core changes.

Built on the open spec

Implements the SKILL.md format and the well-known discovery endpoint from agentskills.io. Lock-file interop with the broader ecosystem - the same skill installed by any spec-compliant tool is visible to all of them.
