What is presets.dev angular.instructions.md?

A set of path-specific instructions for GitHub Copilot when working on Angular, a framework for web applications. It covers standalone components, signals, templates, forms, and the project's Angular version.

Use it when creating or editing Angular components, services, templates, forms, routes, and reactive state.

It keeps generated components consistent with the repository's Angular style and avoids mixing incompatible dependency or component patterns. It also tells the agent to preserve the project's existing setup unless a change is requested.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01019	$0.01019
Opus 5.5	$0.00408	$0.00408
Sonnet 5.5	$0.00204	$0.00204
Haiku 4.5	$0.00102	$0.00102

Security

Grade A, and why

presets.dev angular.instructions.md 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 today.

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.

Angular Copilot Instructions: Standalone Components, Signals and Forms

Path-specific Copilot instructions for Angular. They apply through applyTo and leave .github/copilot-instructions.md in place.

Updated for Angular 22.2.6, Nov 2026

Do not upgrade dependencies or the framework version unless the task asks.

Project shape

New components are standalone. They declare imports for the directives they use. Templates use @if, @for, and @switch. That control flow has been the standard since v17. It is not a v22 feature. On v22, OnPush is the default change detection. The old Default strategy is named Eager. Do not set ChangeDetectionStrategy.Default on a new component. A feature is a set of standalone components and a route, not a new module, unless the repository is still on the module style and the task did not ask to convert it.

A new service uses @Service() and inject(). That decorator does not support constructor injection. Keep @Injectable when you need a constructor, useClass, or a non-root scope. injectAsync is the async form of inject() when the project is on a version that exports it. Do not generate a constructor-injected @Service.

Routes are lazy where the app already lazy-loads. Provide services at the route or the root the project already chose. Do not provide the same stateful service in every component.

Signals and templates

Own state in a signal. Derive with computed. Use input() and output() on a new component when the project is on a version that has them. An effect is for a side effect, and it must not write a signal that retriggers itself. If the effect loops, move the value into a computed.

The template calls signals as functions. Do not read a signal once in the constructor and cache the plain value for the life of the component.

Forms

On v22, a new form uses Signal Forms when the project has already adopted them. Follow the existing form helper if the app has not migrated. Do not mix a new Signal Form and a legacy FormGroup in the same form.

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.
