What is _body-metrics_ AGENTS.md?

Repository instructions for BodyMetrics, a Flutter health app that records measurements and calculates body mass index (BMI). They explain the project structure, technologies, navigation, and rules an AI coding agent must follow.

Use them when changing the app's screens, data storage, network code, tests, localization, routing, architecture, or dependency setup.

They give an agent the project context and conventions needed to make changes that fit the existing codebase, including checking the main Flutter rules before implementation.

Token cost

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	$0.05886	$0.05886
Opus 5	$0.02943	$0.02943
Sonnet 5	$0.01177	$0.01177
Haiku 4.5	$0.00589	$0.00589

Security

Grade A, and why

_body-metrics_ AGENTS.md 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 9d 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.

AGENTS.md — BodyMetrics Project

This file is designed for general AI coding agents. It provides everything needed to understand, navigate, and contribute to this repository.

Mandatory Agent Rule

Before making any Flutter/Dart code, test, architecture, UI, localization, DI, routing, or cache/API decision in this repository, read and follow flutter_rules.md.

Treat flutter_rules.md as the primary implementation convention guide for this codebase.
If a generated suggestion conflicts with repo conventions, prefer flutter_rules.md.
Re-check flutter_rules.md before major refactors and before writing new feature code.

1) Project Goal

Health metrics tracking app (Flutter):

User onboards → picks avatar, enters name/gender/height
Enters weight → BMI automatically calculated and stored
Home screen shows historical measurements as cards and charts

2) Architecture

Stack: Flutter + BLoC/Cubit + Clean Architecture + sqflite + Dio (REST API) + auto_route + injectable/get_it

lib/
├── core/          # Shared infrastructure (router, theme, widgets, extensions, constants)
├── data/          # SQLite cache + REST API (Dio client, services, interceptors)
├── domain/        # Global entities, use cases, repository contracts
├── feature/       # Feature-based modules (each has presentation + optional domain)
│   ├── splash/
│   ├── onboard/
│   ├── avatar_picker/
│   ├── user_general_info/
│   ├── gender/
│   ├── height/
│   ├── weight_picker/
│   └── home/
└── injection/     # GetIt + Injectable DI setup (locator.dart, locator.config.dart)

Layers (per feature):

presentation/ → View + Cubit + State
domain/ → UseCase + Repository (abstract)
data/ (in lib/data/) → Cache implementations (sqflite) + API services (Dio)

Routes defined in lib/core/router/app_router.dart (auto_route):

SplashView → OnboardView → AvatarPickerView → UserGeneralInfoView
          → GenderView → HeightView → WeightView → HomeView
