A guide to organizing multiple applications and shared code libraries in one repository, called a monorepo.

In plain words
What is it for?
Use it to configure Turborepo or Nx, organize packages, set build pipelines and caching, and plan a move from separate repositories.
Why use it?
It helps teams choose a workspace structure and manage shared dependencies, builds, and incremental changes as the codebase grows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

monorepo-setup-guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Monorepo Setup Guide

Before you start

Gather the following from the user:

  1. Which tool? (Turborepo, Nx, or help deciding)
  2. What packages will exist? (Apps, shared libraries, configs)
  3. Package manager? (pnpm, npm, yarn — pnpm recommended for monorepos)
  4. What language/framework? (TypeScript, React, Next.js, Node.js, mixed)
  5. Existing repo or greenfield? (Migrating from multi-repo or starting fresh)
  6. Team size? (Affects caching and CI strategy)

If the user says "set up a monorepo," push back: "What packages do you need? I need to know the apps, shared libraries, and your package manager to design the workspace structure."

Turborepo vs Nx decision guide:

  • Turborepo: Simpler mental model, zero-config caching, good for TypeScript/JS monorepos under 20 packages.
  • Nx: More features (generators, affected commands, module boundary rules), better for large monorepos (20+ packages) or polyglot stacks.

Procedure

Step 1: Define the workspace structure

monorepo/
  apps/
    web/                  # Next.js frontend
    api/                  # Express/Fastify backend
    mobile/               # React Native app
  packages/
    ui/                   # Shared component library
    config-eslint/        # Shared ESLint config
    config-typescript/    # Shared tsconfig
    shared-utils/         # Shared utility functions
    database/             # Database client and schema
  tooling/
    scripts/              # Build and maintenance scripts
  turbo.json              # or nx.json
  package.json            # Root workspace config
  pnpm-workspace.yaml     # Workspace package globs

Rules for package organization:

  • apps/ contains deployable applications. Each has its own build output.
  • packages/ contains shared libraries consumed by apps or other packages.
  • Config packages (config-*) export shared tool configurations.
  • Every package has its own package.json with a name field using a scope: @repo/ui.

Step 2: Configure the workspace root

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
