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 | $0.00081 | $0.02006 |
| Opus 5.5 | $0.00032 | $0.00802 |
| Sonnet 5.5 | $0.00016 | $0.00401 |
| Haiku 4.5 | $0.00008 | $0.00201 |
Grade A, and why
flutter-workshop-builder 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 today.
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.

Flutter Hands-on Workshop Builder Skill
Purpose
Automates the end-to-end creation of technical hands-on workshops focused on Flutter Generative AI cross-platform applications. Enforces clean architecture, Material 3 UI design, state management best practices, the official google_generative_ai Dart SDK, and official Flutter Agent Plugins (github.com/flutter/agent-plugins) & Package Skills (docs.flutter.dev/ai/package-skills).
Pre-Flight Web Research Protocol: Before generating Flutter workshop materials or code, verify the latest versions on
pub.devforgoogle_generative_ai,genui, and check Flutter AI tooling documentation atdocs.flutter.dev/ai/get-started.
🛠️ Official Flutter Agent Plugins & Skills Ecosystem
Flutter hands-on workshops should actively leverage the official Flutter Agent Plugins (github.com/flutter/agent-plugins), the Dart & Flutter MCP Server, and Package Skills (docs.flutter.dev/ai/package-skills) to automate layout generation, UI debugging, and testing:
1. Installing Official Flutter Agent Skills
# Option A: Install via Universal Skills CLI
npx skills add flutter/agent-plugins --skill '*' --agent universal --yes
# Option B: Scan & discover bundled skills from pub.dev dependencies
dart run skills@ get
2. Official Flutter Agent Skills Integration Matrix
When building hands-on labs, AI coding assistants should invoke these specialized skills for specific development tasks:
| Specialized Flutter / Dart Skill | Workshop Lab Application |
|---|---|
flutter-build-responsive-layout |
Build adaptive layouts with LayoutBuilder / MediaQuery across Web, Tablet, and Mobile |
flutter-fix-layout-issues |
Diagnose and resolve RenderFlex overflowed errors and unbounded constraints in AI chat UI |
flutter-apply-architecture-best-practices |
Structure clean layered architecture (UI, Business Logic, Data layer) |
flutter-setup-declarative-routing |
Configure declarative URL-based routing via go_router for Web & deep linking |
flutter-implement-json-serialization |
Create type-safe data models with fromJson / toJson for Gemini API payloads |
flutter-add-widget-test |
Implement component-level tests with WidgetTester for prompt input & streaming views |
flutter-add-integration-test |
Automate end-to-end user flows on emulator, physical device, or Chrome |
dart-run-static-analysis |
Run dart analyze and execute dart fix --apply for mechanical code cleanup |
dart-fix-runtime-errors |
Fetch active runtime stack traces, locate failing lines, and verify with hot reload |
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-workshop-builder is a skill published in the GitHub repository JAICHANGPARK/workshop-harness (5 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 2,006 once invoked, about $0.0003 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.
