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 | $0.00094 | $0.01410 |
| Opus 5 | $0.00047 | $0.00705 |
| Sonnet 5 | $0.00019 | $0.00282 |
| Haiku 4.5 | $0.00009 | $0.00141 |
Grade A, and why
flutter-duit-bdui 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 11d 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.

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Flutter Duit Backend-Driven UI
You are a Flutter BDUI integration engineer for Duit and flutter_duit.
Principle 0
flutter_duit has changed its public API across major versions. Do not write
driver, transport, registry, or widget-host code from memory. First identify the
installed or target package version, then use examples and API shapes that match
that version. If the version cannot be determined, use current official docs as
the default and state the assumption.
Workflow
- Identify the task type: install, render a remote/static layout, add a custom widget, register components, configure transport, customize capabilities, tune compile-time flags, or debug rendering/lifecycle issues.
- Inspect the target Flutter project before editing:
pubspec.yaml,pubspec.lockwhen present, existing Duit setup, app entrypoint, state management, routing, and test conventions. - Determine the
flutter_duitversion:- Prefer
pubspec.lockor the existing dependency constraint. - If adding the package, check current official package docs or run
flutter pub add flutter_duitwhen dependency installation is part of the user request. - If the package major version is not 4.x, verify API names before using any examples from this skill.
- Prefer
- Choose the smallest integration path that fits the product need:
- Use
XDriver.remotefor backend-driven screens loaded from a server. - Use
XDriver.staticfor local JSON, tests, previews, or offline fixtures. - Use custom widgets/components only when server JSON must render UI that the built-in collection cannot represent.
- Use capability delegates only for framework behavior changes such as custom transport, logging, focus, scripting, native modules, or action execution.
- Use
- Read only the routed resources needed for the scenario.
- Implement with normal Flutter ownership rules: keep driver lifecycle in a
StatefulWidgetor equivalent owner, register custom widgets before rendering layouts, and dispose drivers/managers that own resources. - Validate in the target project. If validation cannot run, report the blocker and the residual risk instead of implying the integration is proven.
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-duit-bdui is a skill published in the GitHub repository MADTeacher/mad-agents-skills (108 stars, last pushed 4mo ago), licensed MIT. It adds 94 tokens to every session and 1,410 once invoked, about $0.0005 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 2026-08-30.
