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 | $0.00083 | $0.00842 |
| Opus 5.5 | $0.00033 | $0.00337 |
| Sonnet 5.5 | $0.00017 | $0.00168 |
| Haiku 4.5 | $0.00008 | $0.00084 |
Grade A, and why
angular-reactivity 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 2mo 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.

Angular Reactivity — Signals + RxJS
Signals handle state; RxJS handles streams. They interop via toSignal() and toObservable().
When to Use What
| Use Signals | Use RxJS |
|---|---|
| UI state (loading, error, filters) | Async event streams (click, submit) |
| Derived/computed values | debounceTime, distinctUntilChanged |
| Simple read/write state | switchMap, exhaustMap, combineLatest |
| Template bindings | Dialog handling (race, firstValueFrom) |
| Component inputs/outputs | Complex async orchestration |
Signal Essentials
// Writable
private readonly _items = signal<Entity[]>([]);
readonly items = this._items.asReadonly();
// Modify
this._items.set(newItems);
this._items.update(items => items.filter(i => i.id !== id));
// Computed (auto-updates)
readonly hasItems = computed(() => this._items().length > 0);
// linkedSignal (resets when source changes)
readonly selectedId = linkedSignal({
source: this.items,
computation: (items, prev) =>
prev && items.some(i => i.id === prev.value) ? prev.value : items[0]?.id ?? null,
});
Interop (Critical Patterns)
toSignal() — Observable to Signal
import { toSignal } from '@angular/core/rxjs-interop';
import { startWith } from 'rxjs';
// ALWAYS use startWith() to emit initial value
private readonly formStatus = toSignal(
this.form.statusChanges.pipe(startWith(this.form.status)),
{ initialValue: this.form.status }
);
toObservable() — Signal to Observable
import { toObservable } from '@angular/core/rxjs-interop';
combineLatest([toObservable(this._keyword), toObservable(this._page)])
.pipe(
debounceTime(100),
switchMap(() => this.fetchData()),
takeUntilDestroyed(this.destroyRef)
)
.subscribe();
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-reactivity is a skill published in the GitHub repository cuongtl1992/vibe-skills (11 stars, last pushed 7mo ago), licensed MIT. It adds 83 tokens to every session and 842 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
