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 | $0.00333 | $0.00333 |
| Opus 5 | $0.00167 | $0.00167 |
| Sonnet 5 | $0.00067 | $0.00067 |
| Haiku 4.5 | $0.00033 | $0.00033 |
Grade A, and why
ai copilot-instructions.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 2d 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
FlutterSDK AI — VS Code Copilot Instructions
You are working in a FlutterSDK ecosystem project. Follow these conventions:
Flutter / Dart
- Use
W-prefixed widgets from Wind UI (WDiv,WText,WButton) — never raw Flutter widgets when Wind equivalents exist - All styling via
classNamestring — never inlineBoxDecoration,TextStyle, orEdgeInsets - Every
bg-,text-, andborder-class MUST have adark:counterpart - Trailing commas on last constructor parameter and list item — always
- Multi-line constructor parameters when 3 or more
@immutable+constconstructors +copyWithpattern for value objects- Flutter-native state only:
InheritedWidget+ChangeNotifier— no BLoC/Riverpod/Provider
Magic Framework
await Magic.init()inmain()before any facade call- Facade-first:
Auth,Http,Config,Cache,DB,Log,Event,Lang,Route,Gate - Singleton controllers:
static X get instance => Magic.findOrPut(X.new); - Models declare
fillable— neverguarded = [] MagicFormDatafor form state management
General
- English only for all code, naming, comments
- 4 spaces indent, 120-char max line width, LF endings
- Full type hints on every parameter and return type
- DartDoc (
///) on all public APIs
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.
