Use when implementing new behavior or fixing bugs via tests-first (TDD) in VS Code Copilot Agent mode.
5d-reflect

"Extract learning from completed work to improve future cycles. Use when: (1) After VERIFY phase shows feature complete, (2) End of development iteration, (3) User asks for 'retrospective,' 'lessons learned,' or 'what went well/wrong,' (4) Before starting next major feature. This phase prevents repeating mistakes and compounds learning."

refactor:flutter
by SnakeO
Refactor Flutter/Dart code to improve maintainability, readability, and performance. This skill applies Dart 3 features like records, patterns, and sealed classes, implements proper state management with Riverpod or BLoC, and uses Freezed for immutable models. It addresses monolithic widgets, missing const constructors, improper BuildContext usage, and deep nesting. Apply when you notice widgets doing too much, performance issues from unnecessary rebuilds, or legacy Dart 2 patterns.
refactor:pandas
by SnakeO
Refactor Pandas code to improve maintainability, readability, and performance. Identifies and fixes loops/.iterrows() that should be vectorized, overuse of .apply() where vectorized alternatives exist, chained indexing patterns, inplace=True usage, inefficient dtypes, missing method chaining opportunities, complex filters, merge operations without validation, and SettingWithCopyWarning patterns. Applies Pandas 2.0+ features including PyArrow backend, Copy-on-Write, vectorized operations, method chaining, .query()/.eval(), optimized dtypes, and pipeline patterns.
hm-coding-philosophy
by humanmade
Human Made engineering principles and code quality standards. Apply when writing code, reviewing code, planning implementations, or discussing architecture. Covers code quality priorities, simplicity over complexity, and avoiding over-engineering.
create-test
by kvnwolf
Write automated tests following TDD principles: red-green-refactor, vertical slices, behavior over implementation. Consult this skill whenever creating tests, adding test coverage, writing test-first code, fixing a bug with a regression test, or any task that involves verifying behavior through automated tests.
git-commit
by LukasStrickler
"Write clear git commits with Conventional Commits format. Detects project conventions from history and config. Guides commit granularity. Use when: (1) Completing working code, (2) Code builds and tests pass, (3) Ready to save, (4) Before pushing, (5) After review feedback. Triggers: automatically when finishing commitable work that builds and passes tests."
