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 | $0.00093 | $0.02204 |
| Opus 5.5 | $0.00037 | $0.00882 |
| Sonnet 5.5 | $0.00019 | $0.00441 |
| Haiku 4.5 | $0.00009 | $0.00220 |
Grade A, and why
angular-feature-flags 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Standard IDs
| ID | Severity | What it checks |
|---|---|---|
| AFF-001 | P1 | Feature flag hardcoded as a build-time environment.ts boolean instead of a runtime-evaluated flag |
| AFF-002 | P0 | Flag key names not contracted with the backend, causing silent desync |
| AFF-003 | P2 | Flag checks scattered as ad-hoc conditionals instead of a centralized service/directive |
| AFF-004 | P1 | No fallback behavior when the flag-evaluation endpoint is unreachable at startup |
| AFF-005 | P2 | Fully-rolled-out flag never removed, leaving permanent dead conditional branches |
| AFF-006 | P0 | Flag-gated UI with no matching server-side enforcement of the same restriction |
Check A — Flag baked into environment.ts at build time (AFF-001)
Detection
Grep environment.ts/environment.prod.ts for boolean properties like enableNewCheckout: true. Because these values are compiled into the bundle, toggling the flag requires a full
rebuild and redeploy of the SPA — defeating the entire point of feature flagging, which is
to decouple deployment from release. It also means every environment tier (dev/staging/prod)
needs its own bundle just to differ on flag state.
BAD — compiled-in flag constant
// environment.prod.ts
export const environment = {
production: true,
enableNewCheckout: false, // toggling this means a full rebuild + redeploy
};
// checkout.component.ts
export class CheckoutComponent {
showNewFlow = environment.enableNewCheckout;
}
GOOD — runtime-evaluated flag via a shared service
@Injectable({ providedIn: 'root' })
export class FeatureFlagService {
private http = inject(HttpClient);
private flags = signal<Record<string, boolean>>({});
async loadFlags(): Promise<void> {
const flags = await firstValueFrom(this.http.get<Record<string, boolean>>('/api/features'));
this.flags.set(flags);
}
isEnabled(key: string): boolean {
return this.flags()[key] ?? false;
}
}
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-feature-flags is a skill published in the GitHub repository AgenticPawan/FullStack-Pilot (2 stars, last pushed 2mo ago), licensed MIT. It adds 93 tokens to every session and 2,204 once invoked, about $0.0004 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.
