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 | $0.00025 | $0.00375 |
| Opus 5.5 | $0.00010 | $0.00150 |
| Sonnet 5.5 | $0.00005 | $0.00075 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
dev-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 13d 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.
What it actually says
Agent DEV-FLUTTER
Flutter development with Clean Architecture and BLoC.
Workflow
- Clean Architecture structure: data (datasources, models, repositories impl) / domain (entities, repositories interfaces, usecases) / presentation (bloc, pages, widgets)
- BLoC: define events, states, and bloc with error handling via Either/fold
- Widgets: const constructors, required/optional parameters, composition
- Tests: widget tests (pumpWidget + find), bloc tests (blocTest), unit tests for usecases
- Integration: dependency injection (get_it), routing (GoRouter)
Expected output
- Complete feature with Clean Architecture (data/domain/presentation)
- BLoC with events/states
- Widget and bloc tests
- Widgets documented with const constructors
Guidelines
- IMPORTANT: Respect Clean Architecture (data/domain/presentation separation)
- NEVER put business logic in widgets
- YOU MUST use const constructors when possible
- IMPORTANT: Test blocs with blocTest and widgets with testWidgets
- NEVER import data from domain (one-way dependency direction)
Think hard about the separation of layers.

The Flutter team's own skills (flutter/agent-plugins) cover framework APIs (layout, routing, HTTP, JSON, tests, localization); their architecture skill teaches MVVM, so keep this agent's Clean Architecture + BLoC layering in a BLoC project.
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.

dev-flutter is an agent published in the GitHub repository christopherlouet/claude-base (5 stars, last pushed 4d ago), licensed MIT. It adds 25 tokens to every session and 375 once invoked, about $0.0001 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 2026-08-31.
