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 | $0.00042 | $0.00943 |
| Opus 5 | $0.00021 | $0.00472 |
| Sonnet 5 | $0.00008 | $0.00189 |
| Haiku 4.5 | $0.00004 | $0.00094 |
Grade A, and why
create-project 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Project
Scaffold a new Dart or Flutter project using Very Good CLI templates.
Core Standards
- Use the Very Good CLI MCP server to scaffold projects and install dependencies
- Infer the template from context — determine the right template based on what the user wants to build, not by asking them to pick a subcommand name
- Use
AskUserQuestiononly for information you cannot infer — project name and organization are the most common missing pieces - Install dependencies after creation
Workflow
Step 1: Understand What the User Wants to Build
Infer the subcommand from the user's description — the available subcommands and their descriptions are defined by the Very Good CLI MCP server. Do NOT ask users to pick a subcommand name — figure it out from context.
If the intent is ambiguous, use AskUserQuestion to clarify with a high-level question about what they're building — not which subcommand they want.
Step 2: Gather Missing Parameters
Use AskUserQuestion to collect only what you cannot infer. Batch questions into a single call when possible. Do NOT ask for optional parameters (description, output directory, application ID, etc.) unless the user brings them up.
Step 3: Create and Set Up
- Create the project using the Very Good CLI MCP server
- Install dependencies using the Very Good CLI MCP server — pass
directory: '<path-to-created-project>'topackages_getso it runs against the new project, not the workspace root
Key Domain Knowledge
- Use
dart_package(notflutter_package) for data layer and repository layer packages in the layered-architecture pattern — these must not depend on Flutter SDK - If a user provides a project name with dashes, convert to underscores — Dart package names only allow lowercase letters, numbers, and underscores
- Templates that produce apps, plugins, or games require an organization name — do not skip this or it defaults to a placeholder value
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.

create-project is a skill published in the GitHub repository VeryGoodOpenSource/vgv-ai-flutter-plugin (157 stars, last pushed 13d ago), licensed MIT. It adds 42 tokens to every session and 943 once invoked, about $0.0002 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.
