Repo Sdk

A pnpm monorepo that builds and documents @repo/sdk, a TypeScript SDK you can use as a library or expose to AI agents via the Model Context Protocol (MCP).

What it does

• @repo/sdk – TypeScript package that provides:

  • printWorkingDirectory(directory) – Returns the current working directory for a given path (useful when agents need to resolve paths).
  • reviewDiffsBeforeCommit(cwd?) – Runs git diff HEAD in the given directory, sends the diff to the Claude Code CLI for review, and returns the review text. Optional .claude/skills/review-code/SKILL.md is used when present.

• MCP server – The same SDK is exposed as an MCP server over stdio so tools like Cursor, Claude Desktop, or other MCP hosts can call these functions as tools (e.g. “review my diffs before commit”, “print working directory”).

• Docs – A VitePress site in apps/docs that documents the SDK and is kept in sync via TypeDoc.

Repo structure

Path	Description
packages/sdk	@repo/sdk – main library + MCP server entrypoint
packages/tsconfig	Shared TypeScript configs
packages/eslint-config	Shared ESLint config
apps/docs	VitePress documentation site

Build and orchestration: pnpm workspaces + Turbo.

Requirements

• Node.js ≥ 18
• pnpm (see packageManager in root package.json)
• For reviewDiffsBeforeCommit: Claude Code CLI installed and on PATH

Commands (from repo root)

pnpm install          # Install dependencies
pnpm run build        # Build all packages (no docs)
pnpm run build:all    # Generate docs + build all
pnpm run dev          # Run dev tasks (e.g. docs dev server)
pnpm run lint         # Lint all packages
pnpm run format       # Format with Prettier
pnpm run format:check # Check formatting

Using the SDK

As a library:

pnpm add @repo/sdk

import { printWorkingDirectory, reviewDiffsBeforeCommit, SDK_VERSION } from "@repo/sdk";

console.log(printWorkingDirectory("/some/path"));
console.log(reviewDiffsBeforeCommit()); // uses process.cwd()

As an MCP server:

The package ships a binary repo-sdk-mcp. Point your MCP client at it (stdio transport). Example Cursor config:

{
  "mcpServers": {
    "@repo/sdk": {
      "command": "npx",
      "args": ["-y", "@repo/sdk", "mcp"]
    }
  }
}

Or run the built server directly: node node_modules/@repo/sdk/dist/mcp-server.js (after pnpm install in a project that depends on @repo/sdk).

Documentation

From repo root:

pnpm run docs:generate   # Generate API docs into apps/docs
pnpm --filter docs dev   # Serve docs (if the docs app has a "dev" script)

The docs app lives in apps/docs and consumes the generated API reference.
