monorepo-navigator

monorepo-navigator is a skill for Claude Code, Codex from seaworld008/Commonly-used-high-value-skills. It costs 40 tokens per session (3,401 once invoked), scanned A, original, MIT.

A toolkit for working in a monorepo, a single code repository that contains multiple related apps or packages. It covers common workspace and build tools such as Turborepo, Nx, pnpm, and Lerna.

In plain words
What is it for?
Use it to inspect package relationships, run builds or tests only for affected packages, optimize build workflows, publish package changes, or plan a multi-repository migration.
Why use it?
It helps you see which packages a change affects and avoid rebuilding or testing unrelated code. It also provides guidance for caching, dependency tracking, publishing, and moving several repositories into one.

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; mentions Claude Code.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is # { "extends": ["../../.eslintrc.base.js"] }.

Good fit Use it to inspect package relationships, run builds or tests only for affected packages, optimize build workflows, publish package changes, or plan a multi-repository migration.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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-navigator 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 5d 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 Navigator

Tier: POWERFUL
Category: Engineering
Domain: Monorepo Architecture / Build Systems


Overview

Navigate, manage, and optimize monorepos. Covers Turborepo, Nx, pnpm workspaces, and Lerna. Enables cross-package impact analysis, selective builds/tests on affected packages only, remote caching, dependency graph visualization, and structured migrations from multi-repo to monorepo. Includes Claude Code configuration for workspace-aware development.


Core Capabilities

  • Cross-package impact analysis — determine which apps break when a shared package changes
  • Selective commands — run tests/builds only for affected packages (not everything)
  • Dependency graph — visualize package relationships as Mermaid diagrams
  • Build optimization — remote caching, incremental builds, parallel execution
  • Migration — step-by-step multi-repo → monorepo with zero history loss
  • Publishing — changesets for versioning, pre-release channels, npm publish workflows
  • Claude Code config — workspace-aware CLAUDE.md with per-package instructions

When to Use

Use when:

  • Multiple packages/apps share code (UI components, utils, types, API clients)
  • Build times are slow because everything rebuilds when anything changes
  • Migrating from multiple repos to a single repo
  • Need to publish packages to npm with coordinated versioning
  • Teams work across multiple packages and need unified tooling

Skip when:

  • Single-app project with no shared packages
  • Team/project boundaries are completely isolated (polyrepo is fine)
  • Shared code is minimal and copy-paste overhead is acceptable

Tool Selection

Tool Best For Key Feature
Turborepo JS/TS monorepos, simple pipeline config Best-in-class remote caching, minimal config
Nx Large enterprises, plugin ecosystem Project graph, code generation, affected commands
pnpm workspaces Workspace protocol, disk efficiency workspace:* for local package refs
Lerna npm publishing, versioning Batch publishing, conventional commits
Changesets Modern versioning (preferred over Lerna) Changelog generation, pre-release channels

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.
