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 | $0.00096 | $0.01108 |
| Opus 5.5 | $0.00038 | $0.00443 |
| Sonnet 5.5 | $0.00019 | $0.00222 |
| Haiku 4.5 | $0.00010 | $0.00111 |
Grade A, and why
flutter-app 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
flutter-app
Bootstrap a new Flutter app the way this owner builds them: FVM-pinned SDK, clean architecture (feature-first), Riverpod for state, an Either/Failure error model, current stable packages, and the house git and CI workflow with release-please and Play Store delivery.
First read the shared rules (they override anything you remember):
../shared/house-rules.md, ../shared/no-ai-attribution.md,
../shared/git-and-ci.md, ../shared/docs-and-context.md,
../shared/hardening.md, and (for public repos) ../shared/open-source-docs.md.
Step 0. Get the brief, then ask the variant questions (hard stop)
This is a hard stop. Do not run any scaffolding command until the user has answered.
First, get the project brief: one paragraph on what the app does, its main features, target users, and any hard constraints. If the user has not given one, ask for it. The brief drives naming, the feature list, and the data model.
Then ask the variant questions. If a choice has multiple options, ask; do not assume. Ask in one batch, then proceed.
- Repo visibility: private, open-source, or private-plus-open-source.
- Backend: BYOK (each user supplies their own LLM key, no backend), a custom
backend (Dio + JWT auth), or none yet. See
references/architecture.md. - State codegen: Riverpod with codegen (
@riverpod+ build_runner) or plain Riverpod with hand-written providers. Default: codegen. - Local data: Drift, Isar, shared_preferences only, or none yet.
- Auth: Google Sign-In, none, or backend-driven.
- Release target: Play Store (default), App Store, or both.
If the user already answered some, do not re-ask.
Step 1. Pin the SDK with FVM and verify versions
- Use FVM so the SDK is pinned per project:
fvm use stable(or a specific stable). Every command runs throughfvm flutter .... - Run
fvm flutter --versionand record the real Flutter and Dart versions in the project docs. - Run
scripts/check-latest.shfor current stable package versions from pub.dev. Pin those, not versions from memory (../shared/house-rules.mdrule 2). - Pull current docs for Flutter, Riverpod, and any codegen packages via Context7
before writing code (
../shared/docs-and-context.md). Riverpod's provider syntax and codegen naming change between majors; confirm before writing.
What ships with it
5 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-app is a skill published in the GitHub repository ccplugins/awesome-claude-code-plugins (974 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 96 tokens to every session and 1,108 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 2026-08-30.
