Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is fluttersdk/ai's own configuration. It tells GitHub Copilot how to work on ai itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ai configures →

Token cost

What it costs to keep this loaded

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.

Security

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 className string — never inline BoxDecoration, TextStyle, or EdgeInsets
  • Every bg-, text-, and border- class MUST have a dark: counterpart
  • Trailing commas on last constructor parameter and list item — always
  • Multi-line constructor parameters when 3 or more
  • @immutable + const constructors + copyWith pattern for value objects
  • Flutter-native state only: InheritedWidget + ChangeNotifier — no BLoC/Riverpod/Provider

Magic Framework

  • await Magic.init() in main() 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 — never guarded = []
  • MagicFormData for 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
Changes

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.
