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 | $0.00041 | $0.00818 |
| Opus 5 | $0.00020 | $0.00409 |
| Sonnet 5 | $0.00008 | $0.00164 |
| Haiku 4.5 | $0.00004 | $0.00082 |
Grade A, and why
maestro-flutter 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 12d 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

Reference Guide
| Topic | Reference | Use When |
|---|---|---|
| Flow Patterns | references/flow-patterns.md |
Writing YAML flows, Flutter-specific tips |
| CI & Visual Regression | references/ci-visual-regression.md |
CI/CD setup, visual comparison, troubleshooting |
Core Principles
- ADD semantic labels —
Key()/Semanticson all interactive widgets - WRITE flows in YAML — simple, readable, no code
- RUN on emulator first, then real devices
- CAPTURE screenshots at key assertion points
- USE visual regression for Pixel Perfect validation
TestKeys Pattern (MANDATORY)
// lib/core/constants/test_keys.dart
abstract class TestKeys {
static const emailField = Key('email_field');
static const passwordField = Key('password_field');
static const loginButton = Key('login_button');
static const registerButton = Key('register_button');
static const homeTab = Key('home_tab');
static const profileTab = Key('profile_tab');
static const loadingIndicator = Key('loading_indicator');
static const errorMessage = Key('error_message');

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.

maestro-flutter is a skill published in the GitHub repository aleksandr-chaika/flutter-clean-arch-skills (5 stars, last pushed 6mo ago), licensed MIT. It adds 41 tokens to every session and 818 once invoked, about $0.0002 per session on Opus 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.
