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.

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 | $0.00000 | $0.01563 |
| Opus 5.5 | $0.00000 | $0.00625 |
| Sonnet 5.5 | $0.00000 | $0.00313 |
| Haiku 4.5 | $0.00000 | $0.00156 |
Grade A, and why
add-notification-feature 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
add-notification-feature
Adds Firebase Cloud Messaging (FCM) push notifications to one app under
apps/{app}/: device token, foreground/background/terminated handling, topic
subscriptions, tap-to-open-a-page routing, and image (rich) notifications.
FCM only — no CleverTap.
The guide is split into platform tracks — present the steps separated by iOS and Android so the user can follow only the platform(s) they ship:
- Part A — Shared Flutter code (deps + Dart): identical for both platforms; always do it.
- Part B — iOS track: Apple/Firebase credential + Xcode capabilities.
- Part C — Android track: manifest permission + channel.
- Part D — Test: separate iOS and Android instructions.
Follow every step in the guide below. Notes on how this skill splits the work:
1. Pick the app, platform(s), and confirm Firebase is connected
If the app was not passed as an argument, list apps/ and ask which one. Also ask
which platform(s) it targets — that decides whether you do Part B, Part C, or
both.
This skill builds on /connect-firebase — it does not run the FlutterFire
CLI itself. Verify the app is already connected:
ls apps/{app}/lib/firebase_options.dart
grep -n "firebase_core" apps/{app}/pubspec.yaml
grep -n "Firebase.initializeApp" apps/{app}/lib/main.dart
If any is missing → stop, tell the user to run /connect-firebase first, then
return here.
2. Part A — shared Flutter code (agent, both platforms)
Add firebase_messaging + flutter_local_notifications to this app's
pubspec.yaml (never core), then create under
apps/{app}/lib/services/notification/ the payload, navigator key, local
notification service, router, and FirebaseMessagingService (static singleton — not
in GetIt), plus notification_type.dart enums. Register the background handler in
main.dart; call FirebaseMessagingService.instance.init() from the home
screen's addPostFrameCallback. This part is platform-agnostic.
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.

add-notification-feature is a skill published in the GitHub repository abhinav503/flutter-agentic (10 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,563 tokens. 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.
