+title: RushStack Skill
+---
+
+[Rush MCP server](./rush_mcp.md) provides a powerful way to integrate Rush with AI coding assistants using the Model Context Protocol. **RushStack Skill** take a different approach, providing a comprehensive knowledge base that AI agents can load on-demand to better understand Rush monorepo best practices.
+
+## What are skills?
+
+[Skills](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/overview) are reusable knowledge packages that AI agents can dynamically load to gain expertise in specific domains. Unlike static context files, skills:
+
+- **Are modular, self-contained packages** that provide specialized knowledge, workflows, and best practices for specific domains
+- **Transform AI from a general-purpose agent** into a specialized agent equipped with procedural knowledge that cannot be fully learned from pre-training data
+- **Use progressive disclosure** - metadata stays in context, body loads on-trigger, and bundled resources load only as-needed, optimizing token usage
+- **Can be automatically discovered** when the agent detects relevant project indicators (e.g., `rush.json`)
+
+## The RushStack skill
+
+The **rushstack-best-practices** skill provides AI agents with comprehensive knowledge about working with Rush monorepos. It includes:
+
+- **Core Principles**: Essential guidelines for Rush monorepo development
+- **Command Usage**: Best practices for `rush`, `rushx`, and `rush-pnpm` commands
+- **Project Selection**: Proper use of selection flags like `--to`, `--from`, `--impacted-by`
+- **Dependency Management**: Adding/removing dependencies, version constraints, workspace linking
+- **Build Optimization**: Incremental builds, build cache configuration, parallel execution
+- **Subspace**: Using subspaces for large monorepos with isolated dependency trees
+- **Troubleshooting**: Common issues and solutions
+
+## Installation
+
+### Using npx skills add
+
+The RushStack skill can be installed using the `npx skills add` command:
+
+```bash
+npx skills add https://github.com/microsoft/rushstack/tree/main/skills
+```
+
+This command will:
+
+1. Download the latest version of the skill
+2. Prompt you to select which AI agent to install the skill for
+3. Install the skill in the selected agent's skills directory
+4. Make it available for automatic loading when working in Rush monorepos
+
+The skill will be **automatically loaded** when the AI agent detects a `rush.json` file in your workspace root, ensuring the agent has Rush-specific knowledge when working in your monorepo.
