How to use the Angular Expert agent skill: install and trigger it

What is an agent skill and what does this one do?

An agent skill is a folder containing a SKILL.md file and supporting reference files. When a request matches the skill's description, the agent reads those instructions and follows them while it works. The angular skill is described as a modern Angular (v20+) expert with knowledge of Signals, Standalone Components, Zoneless applications, SSR/Hydration and reactive patterns.

In practice the skill steers the agent toward modern Angular patterns: Signals for reactive state, standalone components instead of NgModules, zoneless change detection, and server-side rendering with hydration. It also adds safety cautions, such as keeping server-side state per request and enforcing authorization on the server rather than only in route guards.

Install the Angular Expert skill

Download the skill ZIP from this page and unzip it. The skill folder is named angular and contains metadata.json, README.md, SKILL.md and references/detailed-guide.md.

For Claude Code, put the unzipped angular folder in ~/.claude/skills/ to make it available across your projects, or in a project's .claude/skills/ folder to limit it to that project.

In the Claude apps, you can upload the skill instead under Settings → Capabilities → Skills.

• Keep the references/detailed-guide.md file alongside SKILL.md; the skill reads it before running.
• Check that the folder name and file layout match the ZIP contents before relying on the skill.

How do you trigger the skill with a natural request?

You do not need a special command. Describe the Angular task in plain language and mention the version or feature you care about. The skill's description covers new Angular v20+ applications, Signals-based reactive state, migrating from NgModules to standalone components, zoneless configuration, SSR, prerendering and hydration, and performance work.

Requests that fit well include a clear goal and the current state of your project, for example what version you run and what you want to change.

• "Set up a new Angular v20 app with standalone components and Signals for the product list."
• "Help me move this feature from an NgModule to standalone components without a big-bang rewrite."
• "Configure zoneless change detection in my Angular project."
• "Add SSR with hydration and make sure user state is not shared between requests."

What kinds of examples and output should you expect?

The guide covers modern component patterns with Signal inputs and outputs, state management with Signals and computed values, performance techniques, SSR and hydration practices, and migration strategies from older Angular patterns. The examples are fragments: they omit project imports, types and components such as ItemComponent, HeaderDirective, User and Product, so you must supply their real definitions.

Expect the agent to flag version-specific details. The guide notes that provideZonelessChangeDetection is stable from 20.2, that zoneless is the default in v21+, and that Signal Forms appeared experimentally in v21.

• Product loading examples are expected to handle cancellation of stale responses, an error state, and repeated calls.
• Route guards improve navigation but every server endpoint must still enforce authorization.
• Use template imports and meaningful labels or alt text in complete components.

What does the skill need and what are its safety limits?

The skill requires an Angular v20+ project and read access to the bundled references/detailed-guide.md file. It does not run scripts and does not use the network.

The skill's own safety rules are to test changes in development before production, migrate existing apps gradually rather than in one big refactor, and keep backward compatibility during transitions. The guide itself has not been compiled or browser-tested, so validate every output with your build and tests.

Do not log real form or account data, and configure SSR state and cache providers per request to avoid leaking data between users.

• Not for AngularJS (1.x) migration; the skill points those tasks to a separate angular-migration skill.
• Not for legacy Angular apps that cannot be upgraded, because the skill targets modern versions.
• General TypeScript problems are routed to a typescript-expert skill.

Tips for getting reliable results

Give the agent your Angular version and a short description of the project before asking for changes. Because the skill targets v20+, that detail decides which patterns apply.

Ask for incremental changes. The skill itself advises gradual migration, and smaller steps are easier to test. Constructor injection and @Input remain supported, so the agent should migrate them only when there is a concrete benefit.

• Name the feature you want (for example SSR, zoneless or Signals) so the agent loads the right section.
• Ask the agent to add loading, error and cancellation handling when it writes data-fetching code.
• Review every generated file and run your build and tests before merging.
