Refactoring
Code restructuring and optimization
rebuild
by luan
"Collapse branch into working tree and rebuild as clean, refined commits with code improvements per commit. Triggers: 'rebuild branch', 'rebuild commits', 'clean up and improve branch'. Unlike /split-commit which preserves the exact diff, rebuild applies refinements and simplifications to each commit."
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.
split-commit
by luan
"Collapse a branch into working tree and repackage as clean, tested, vertical commits. Triggers: 'split commits', 'repackage commits', 'reorganize commits', 'clean up branch history', 'consolidate commits into clean ones'. Do NOT use when: branch already has a single clean commit or only needs amending — use /commit instead."

prompt-optimizer
by Aznatkoiny
Optimize prompts for Claude 4.x models using Anthropic's official best practices. Use when users want to improve, refine, or create effective prompts for Claude. Triggers include requests to optimize prompts, make prompts more effective, fix underperforming prompts, create system prompts, improve instruction following, reduce verbosity, control output formatting, or enhance agentic/tool-use behaviors. Also use when users report Claude is being too verbose, not following instructions, not using tools properly, or producing generic outputs.
Concurrency
by andrueandersoncs
This skill should be used when the user asks about "Effect concurrency", "fibers", "Fiber", "forking", "Effect.fork", "Effect.forkDaemon", "parallel execution", "Effect.all concurrency", "Deferred", "Queue", "PubSub", "Semaphore", "Latch", "fiber interruption", "Effect.race", "Effect.raceAll", "concurrent effects", or needs to understand how Effect handles parallel and concurrent execution.
