Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00036 | $0.03123 |
| Opus 5 | $0.00018 | $0.01562 |
| Sonnet 5 | $0.00007 | $0.00625 |
| Haiku 4.5 | $0.00004 | $0.00312 |
Grade A, and why
angular-best-practices 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 10d ago.
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.
This is a copy
86% identical to angular-best-practices — 548 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Angular Best Practices
Comprehensive performance optimization guide for Angular applications. Contains prioritized rules for eliminating performance bottlenecks, optimizing bundles, and improving rendering.
When to Apply
Reference these guidelines when:
- Writing new Angular components or pages
- Implementing data fetching patterns
- Reviewing code for performance issues
- Refactoring existing Angular code
- Optimizing bundle size or load times
- Configuring SSR/hydration
Rule Categories by Priority
| Priority | Category | Impact | Focus |
|---|---|---|---|
| 1 | Change Detection | CRITICAL | Signals, OnPush, Zoneless |
| 2 | Async Waterfalls | CRITICAL | RxJS patterns, SSR preloading |
| 3 | Bundle Optimization | CRITICAL | Lazy loading, tree shaking |
| 4 | Rendering Performance | HIGH | @defer, trackBy, virtualization |
| 5 | Server-Side Rendering | HIGH | Hydration, prerendering |
| 6 | Template Optimization | MEDIUM | Control flow, pipes |
| 7 | State Management | MEDIUM | Signal patterns, selectors |
| 8 | Memory Management | LOW-MEDIUM | Cleanup, subscriptions |
1. Change Detection (CRITICAL)
Use OnPush Change Detection
// CORRECT - OnPush with Signals
@Component({
changeDetection: ChangeDetectionStrategy.OnPush,
template: `<div>{{ count() }}</div>`,
})
export class CounterComponent {
count = signal(0);
}
// WRONG - Default change detection
@Component({
template: `<div>{{ count }}</div>`, // Checked every cycle
})
export class CounterComponent {
count = 0;
}
Prefer Signals Over Mutable Properties
// CORRECT - Signals trigger precise updates
@Component({
template: `
<h1>{{ title() }}</h1>
<p>Count: {{ count() }}</p>
`,
})
export class DashboardComponent {
title = signal("Dashboard");
count = signal(0);
}
// WRONG - Mutable properties require zone.js checks
@Component({
template: `
<h1>{{ title }}</h1>
<p>Count: {{ count }}</p>
`,
})
export class DashboardComponent {
title = "Dashboard";
count = 0;
}
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

angular-best-practices is a skill published in the GitHub repository benjaminasterA/antigravity-awesome-skills (256 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 3,123 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to angular-best-practices, differing in 548 lines, and is treated as a copy.
