Automated summary
This skill explains how to set up and operate an Nx monorepo: generating projects, running tasks, caching builds, and using affected commands.
Strengths
- Covers the whole flow from creating the workspace to running tasks
- Shows key commands such as nx affected and nx run-many to target only what changed
- Includes a concrete nx.json example with targetDefaults and cache settings
- Notes that Nx can be added to an existing repo with npx nx init, without plugins
Limitations
- It is a quick start only: no detail on authoring custom plugins, executors, or generators
- Nx Cloud is mentioned in a single line with no setup procedure
- Assumes a Node.js environment and does not walk through Lerna migration beyond a brief mention
Use it when setting up or working in an Nx monorepo, adding build caching, or restricting CI to affected projects.
Avoid it if you need an advanced guide to custom Nx plugins or a detailed migration procedure from another tool.
Security analysis
CautionThe skill instructs standard Nx setup and build commands. No destructive, exfiltrating, or obfuscated actions are present. However, it involves downloading and running code from npm via npx and generators, which is a legitimate but powerful network/execution pattern, so caution is warranted.
- •Uses npx and network to download and execute packages (create-nx-workspace, generators), which introduces supply-chain risk if versions are not pinned.
- •No allowed-tools declared, so executing these commands may require elevated shell access beyond the skill's declared permissions.
Examples
Set up an Nx monorepo called my-org with a React app, a shared JS library, and a Node API, then enable caching for build, test, and lint.Configure our CI pipeline to run nx affected -t lint test build so only projects touched by the pull request are built and tested.We have an existing repository with several packages and no build cache — add Nx with npx nx init and wire up task caching.name: nx description: >- Build and manage monorepos with Nx.

Nx
Overview
Nx is a build system for monorepos. It provides computation caching (local + remote), task orchestration, dependency graph, code generators, and affected commands. Works with React, Angular, Node.js, Next.js, and any language.
Instructions
Step 1: Create Workspace
npx create-nx-workspace@latest my-org --preset=ts
cd my-org
Step 2: Add Projects
nx g @nx/react:app my-app
nx g @nx/js:lib shared-utils
nx g @nx/node:app api
Step 3: Run Tasks
nx serve my-app
nx build api
nx test shared-utils
nx affected -t test # only what changed
nx run-many -t build test # everything
Step 4: nx.json Configuration
// nx.json — Workspace configuration
{
"targetDefaults": {
"build": { "dependsOn": ["^build"], "cache": true },
"test": { "cache": true },
"lint": { "cache": true }
}
}
Guidelines
- Nx caches task results — second run is instant if inputs haven't changed.
- Use nx affected in CI to only build/test what changed in a PR.
- Nx Cloud provides remote caching — share cache across team/CI.
- Nx works without plugins too — add it to any repo with npx nx init.
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/nx-build-and-manage-monorepos-ms47vp5b/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/nx-build-and-manage-monorepos-ms47vp5b' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/nx-build-and-manage-monorepos-ms47vp5b/download' --output '.skill-downloads/nx-build-and-manage-monorepos-ms47vp5b/SKILL.md.part' && mv '.skill-downloads/nx-build-and-manage-monorepos-ms47vp5b/SKILL.md.part' '.skill-downloads/nx-build-and-manage-monorepos-ms47vp5b/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Environment declared by the author: Node.js, any framework
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/nx-build-and-manage-monorepos-ms47vp5b/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
