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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01385 |
| Opus 5 | $0.00000 | $0.00692 |
| Sonnet 5 | $0.00000 | $0.00277 |
| Haiku 4.5 | $0.00000 | $0.00138 |
Grade A, and why
flutter-agent-guidelines 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 3d 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flutter Agent Guidelines
CRITICAL: All Flutter agents MUST follow these discovery rules and reference existing skills/rules
1. Discovery-First Approach
Before making ANY implementation decisions:
# Check dependencies & patterns
grep -A 50 "dependencies:" pubspec.yaml
find lib -name "*_bloc.dart" -o -name "*_repository.dart"
grep -r "BlocProvider\|ChangeNotifier\|GetX" lib/
cat analysis_options.yaml
2. Skills & Rules Reference
All agents MUST reference existing skills and rules instead of duplicating content:
Architecture & Design
- Planning features: Use
design-architecture-skillfor data/domain/view structure - Feature analysis: Use
feature-analysis-skillfor complexity assessment - Architecture rules: Follow
Flutter/rules/architecture.md
Bug Investigation & Debugging
- Debugging: Use
bug-solving-skillfor Flutter-specific patterns - Root cause analysis: Follow layer-by-layer (data/domain/view) investigation
- Foundation: Reference
skills/bug-investigationfor scientific method
Code Quality
- Linting: Follow
Flutter/rules/lint-rules.md- MUST passflutter analyzewith 0 errors - Formatting: Run
dart format .- follow project'sanalysis_options.yaml - Code review: Use
code-review-skill
Testing
- Test structure: Use
Flutter/rules/testing.md - Test patterns: Match project's existing test patterns (bloc_test, mocktail, mockito)
State Management
- Agnostic approach: All agents support Bloc/Provider/GetX/Riverpod
- Check first: Scan project for existing patterns before recommending
- Reference:
design-architecture-skillfor state management templates - Ask when unclear: Multiple patterns or conflicting approaches
Performance & Optimization
- Optimization patterns:
optimization-skillandoptimization-skill/examples.md - Widget rebuilds: Scope state listeners, use const constructors
- Lists: ListView.builder for >20 items, stable keys
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-agent-guidelines is an agent published in the GitHub repository Desquared/agents-rules-skills (4 stars, last pushed 20d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,385 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.
