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 | $0.02225 | $0.02225 |
| Opus 5 | $0.01112 | $0.01112 |
| Sonnet 5 | $0.00445 | $0.00445 |
| Haiku 4.5 | $0.00222 | $0.00222 |
Grade A, and why
vgv-ai-flutter-plugin AGENTS.md 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.
How it starts
The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VGV AI Flutter Plugin
Project Overview
VGV AI Flutter Plugin provides best-practices skills for Flutter and Dart development. It is a documentation-only repository — there is no Dart/Flutter source code, no pubspec.yaml, and no tests. All value lives in the markdown skill files.

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.

vgv-ai-flutter-plugin AGENTS.md is an instructions file published in the GitHub repository VeryGoodOpenSource/vgv-ai-flutter-plugin (160 stars, last pushed today), licensed MIT. It adds 2,225 tokens to every session, about $0.0111 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 2026-09-03.
