Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Skilljack MCP - Developer Guide

## Commands

- `npm run build` - Compile TypeScript to dist/ (two Vite UI builds, `mcp-app` and `skill-display`, then `tsc`)
- `npm run dev` - Watch mode (tsx)
- `npm test` - Run the vitest suite
- `npm run typecheck` - Typecheck both halves (`tsc --noEmit` for the server, `tsconfig.ui.json` for `src/ui`)
- `npm run inspector` - Test with MCP Inspector

CI (`.github/workflows/ci.yml`) runs `npm ci`, `npm run build`, and `npm test` on Node 22 for every push to `main` and every PR against `main`. Node 22+ is required; Node 20 reached end of life in April 2026.

## Two bundles: server and UI

This package spans two independent bundles that share only the MCP wire format:

- **Server half** (everything except `src/ui/**`) is on **MCP TypeScript SDK v2** — `@modelcontextprotocol/server`, `@modelcontextprotocol/server/stdio`, `@modelcontextprotocol/node` (+ `@modelcontextprotocol/client` in tests only) — and registers its MCP Apps tools and resources through `registerAppTool` / `registerAppResource` from `@modelcontextprotocol/ext-apps/server`. Typechecked by the root `tsconfig.json`, which **excludes `src/ui/**`**.

How to install

The exact contents, by fingerprint
mdr add olaservo/skilljack-mcp/CLAUDE.md@sha256:8b0c27e9ae4bf9ad

The line at the top of this page pins the label git:20260928.42f99ee, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
