dart-best-practices from kevmoo/dash_skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Pins git:20260913.6c39005 in mdr.lock. Pin the fingerprint instead.

General best practices for Dart development. Covers code style, effective Dart, and language features.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Dart Best Practices

## 1. When to use this skill

Use this skill when:

- Writing or reviewing Dart code.
- Looking for guidance on idiomatic Dart usage.

### When NOT to use (Abstention Guardrails)

Do NOT apply this skill or refactor code when:

- **Public API Breaking Changes**: Refactoring would alter public API contracts,
  return types, or parameter signatures in published packages without a
  coordinated major SemVer bump.
- **Dogmatic Micro-Optimizations**: Rewriting clear, readable code for
  negligible theoretical gains (e.g. replacing clear string concatenation in a
  simple one-line log message with multiline quotes).
- **Domain-Specific or Code-Generated Files**: Generated files (`*.g.dart`,
  `*.freezed.dart`, protobufs) or files where line lengths and string layouts
  are managed by code generators.
- **Explicit Type Annotations in Public Interfaces**: Replacing explicit type
  annotations with `var` or `final` where explicit types document the public API
  surface or disambiguate complex generics.

## 2. Best Practices

### Multi-line Strings

Prefer using multi-line strings (`'''`) over concatenating strings with `+` and
…

How to install

The exact contents, by fingerprint

mdr add kevmoo/dash_skills/dart-best-practices@sha256:3d208d6fa9f30c35

The line at the top of this page pins the label git:20260913.6c39005, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
