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 | $0.00066 | $0.00462 |
| Opus 5 | $0.00033 | $0.00231 |
| Sonnet 5 | $0.00013 | $0.00092 |
| Haiku 4.5 | $0.00007 | $0.00046 |
Grade A, and why
flutter-flavors 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 5d 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.

Key rules
- Three environments:
Env.dev,Env.uat,Env.prod. Each has its own entry point. Envis a simple enum (dev | uat | prod) with helper getters (isDev,isUat,isProd).EnvConfigmapsEnv→ config values (API base URL, app title, logging enabled, timeouts).AppConfig.fromEnv(env)is the single config object. Created once inmain_*.dartand passed toappBootstrap().- Three entry points:
lib/main_dev.dart,lib/main_uat.dart,lib/main_prod.dart. Each callsappBootstrap(Env.x). API_BASE_URLenv var overrides the config — useful for pointing a dev build at a local server:--dart-define=API_BASE_URL=http://localhost:3000.- No
kDebugModeorkReleaseModechecks — useAppConfig.envinstead (testable, not build-mode-coupled).

What ships with it
4 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.

flutter-flavors is a skill published in the GitHub repository yendangn/flutter-app-builder (5 stars, last pushed 2mo ago), licensed MIT. It adds 66 tokens to every session and 462 once invoked, about $0.0003 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.
