How to use the Angular Best Practices agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Angular Best Practices skill is a set of prioritized Angular performance rules that an AI agent follows when you ask it to write, review or refactor Angular code. It targets large bundles, inefficient data fetching and rendering problems. This guide explains what the skill does, how to install it, how to trigger it and how to use it safely.

- 1Download the ZIP. Download the skill ZIP from this page.
- 2Unzip the skill folder. Unzip the archive so the angular-best-practices folder is available locally.
- 3Place it in the skills folder. Put the folder in ~/.claude/skills/ for personal use or .claude/skills/ inside a project.
- 4Or upload it in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the skill.
- 5Ask for Angular work. Make a plain request such as reviewing a component for performance problems.
- 6Validate the result. Measure bundle size and rendering before and after changes, and test in your own environment.
What the skill makes the agent do
Once installed, the agent applies Angular performance guidance when you work on Angular code. The skill's rules cover change detection (OnPush, Signals, zoneless apps), async operations (avoiding waterfalls, SSR preloading), bundle optimization (lazy loading, @defer, tree-shaking), rendering (TrackBy, virtual scrolling, CDK), SSR and hydration, template optimization, state management and memory management.
The rules are grouped by priority. Change detection, async waterfalls and bundle optimization are labelled critical, and the agent uses these labels to decide what to raise first. The priority labels are triage heuristics, not guaranteed gains.
Install the skill from the ZIP
Download the ZIP for this skill from this page and unzip it. For a personal install, place the unzipped skill folder in ~/.claude/skills/. For a single project, place it in the project's .claude/skills/ folder.
If you use the Claude apps, you can instead upload the skill under Settings → Capabilities → Skills.
- Personal install: ~/.claude/skills/
- Project install: .claude/skills/ inside your project
- Claude apps: Settings → Capabilities → Skills (upload)
Trigger the skill with natural requests
You do not need a special command. Ask for Angular work in plain language and the agent will use the skill when the task matches its scope. The skill is meant for writing new components or pages, implementing data fetching, reviewing code for performance issues, refactoring, optimizing bundle size or load times, and configuring SSR or hydration.
- Review this Angular component for performance problems.
- Refactor this list component to reduce rendering cost.
- Help me lazy load these routes and reduce the bundle size.
- Check this Angular service for data fetching waterfalls.
- Set up hydration for my Angular SSR app.
What to expect from the output
For focused work, the agent loads the relevant sections of the detailed guide. For end-to-end work, it reads the guide in full. The guide asks that you pin the Angular and CDK major versions and inspect the app's existing change-detection and SSR setup first.
Code snippets in the guide are focused fragments. Host services and imports are assumed, so they are not a complete runnable application. Measure bundle sizes and rendering profiles before and after a change to confirm it helped.
- Expect fragments, not a full app.
- Ask the agent to name the Angular and CDK versions it assumes.
- Ask for before-and-after measurements to be part of the plan.
What the skill needs and safety notes
The skill lists no required tools. It does not run scripts and does not use the network. Its files are metadata.json, README.md, references/detailed-guide.md and SKILL.md.
The skill is guidance only. It does not replace testing in your own environment or expert review. Use it only when the task clearly matches its scope, and let the agent stop and ask when required inputs or success criteria are missing.
- Requires: nothing listed
- Runs scripts: no
- Uses network: no
- Not for non-Angular projects such as React, Vue or plain JavaScript
What people use it for
- Reviewing an Angular pull request for change detection or rendering problems.
- Refactoring a list component to use TrackBy or virtual scrolling.
- Reducing bundle size by adding lazy-loaded routes or @defer blocks.
- Finding data fetching waterfalls in Angular services and components.
- Configuring SSR and hydration in an existing Angular app.
Frequently asked questions
Is the Angular Best Practices skill free?
The skill is published under the MIT licence, as stated on this page. Check the licence file in the repository for the full terms before reuse.
What do I need to use the angular-best-practices skill?
The skill lists no required dependencies. It does not run scripts and does not use the network. You need an agent environment that supports skills and an Angular project to work on.
Where do I install an agent skill?
For a personal install, unzip the skill into ~/.claude/skills/. For one project, use the .claude/skills/ folder in that project. In the Claude apps, you can upload it under Settings → Capabilities → Skills.
Does this skill work with React or Vue?
No. The rules are specific to Angular and will not apply to React, Vue or plain JavaScript.
Why does the agent give code fragments instead of a full app?
The guidance uses focused snippets with host services and imports assumed. You need to integrate them into your own application and check them against your Angular and CDK versions.
Can I trust the performance claims without testing?
No. The guidance is general. Measure bundle sizes and rendering profiles before and after each change, and validate the results in your own environment.

Our verdict
Use this skill if you build or review Angular applications and want an agent to check for performance problems and suggest prioritized fixes. Pick something else if your project is not Angular, or if you need a tool that measures your app's real performance, since this skill gives guidance rather than measurements.
