slipstream-packages SKILL.md skillA
slipstream-packages from devoncarew/flutter-slipstream is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add devoncarew/flutter-slipstream/slipstream-packages@git:20260427.0584ad2Pins git:20260427.0584ad2 in mdr.lock. Pin the fingerprint instead.

This skill should be used when about to write Dart or Flutter code that calls into a pub package whose API is uncertain — the package is unfamiliar, or its version in pubspec.lock may be newer than training data. Also load when hitting an unexpected compile error or type mismatch on a package import. Skip for code that only uses the Dart SDK (dart:*) and packages already verified this session.
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# Dart Package API Lookup Training-data summaries for pub packages are often subtly out-of-date: incorrect parameter names, missing required/optional distinctions, wrong constructor shapes, renamed or removed APIs. The `packages` tools read directly from the local pub cache — exact signatures, always matches `pubspec.lock`, no network required. ## Call sequence 1. `package_summary(project_directory, package)` — always start here. Returns version, entry-point import, library list, and exported name groups. Often enough to confirm the right import path and top-level names. 2. `library_stub(project_directory, package, library_uri)` — full public API for one library as Dart signatures (no bodies, no private members). Use when you need exact constructor shapes, named parameter names, or return types. 3. `class_stub(project_directory, package, library_uri, class)` — single class stub including inherited and mixin-contributed members. Use when you know exactly which class you need. `project_directory` is the absolute path to the Dart/Flutter project (the directory containing `pubspec.yaml`). Run `dart pub get` first if `.dart_tool/package_config.json` is missing. …

How to install
mdr add devoncarew/flutter-slipstream/slipstream-packages@sha256:aab2b9c8d612f63cThe line at the top of this page pins the label git:20260427.0584ad2, 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.
