Build Claude Code skills with content-addressable MCP server dependencies
Creates a content-addressable OCI scratch image bundling a set of MCP servers pinned by digest. Invoked when the user asks to create a profile or bundle MCP servers into a content-addressable dependency.
Guides the user through creating a new Claude Code skill with content-addressable MCP server dependencies. Invoked when the user wants to build a skill, create a skill, or author a new slash command.
A collection of Claude Code plugins for building and managing skills with content-addressable MCP server dependencies.
Tools for creating Claude Code skills that pin their MCP server dependencies to immutable OCI digests.
Slash commands:
/skill-builder — End-to-end workflow: collects skill intent, creates a profile, defines tool access, authors skill instructions, and emits the plugin directory./skill-builder:profiles — Standalone profile creation. Useful for creating or updating profiles independently of a full skill build.A profile is a YAML manifest of MCP servers pinned to immutable OCI digests, bundled into a scratch OCI image. Skills reference a profile digest in their frontmatter to guarantee reproducible dependencies across any environment.
See skill-builder/NOTES.md for technical details on profiles, skills, the MCP registry API, and OCI digest resolution.

The repo includes two MCP servers (run as Docker containers) used by the demo skills:
| Server | Purpose |
|---|---|
project-gutenberg-mcp | Fetch book metadata and passages from Project Gutenberg |
append-log-mcp | Append-only JSONL log for tracking events across sessions |
