Run EELS Test Suite
by Sounder25
Automates running the Ethereum Execution Layer Specification (EELS) tests against a local EVM implementation. Handles venv setup, execution, and result parsing.
writing-assistant
by VegetaPn
Comprehensive writing workflow from ideation to publication. Guides users through creating polished articles by collecting ideas, asking clarifying questions, researching content, polishing drafts, adding images, and publishing to platforms like WeChat or X. Use when users want to write articles, blog posts, or long-form content, especially when starting from a topic idea, rough materials, or initial draft. Also use when users mention writing, publishing, or content creation workflows.
Pre-Action Guard
by Sounder25
A QA gate that validates potentially destructive or irreversible actions before execution.
playwright-best-practices
by vitalics
Review code for Playwright Guidelines compliance. Use when asked to "review my playwright tests", "check accessibility", or "check my tests against best practices".
map-reduce
by ElliotJLT
Orchestration pattern for large-scale processing where work is distributed, processed independently, then combined. Map phase splits and processes, Reduce phase aggregates results. Use for codebase-wide analysis, bulk transformations, or any task where "do X to everything, then summarize."
battle-plan
by ElliotJLT
Before ANY significant development task (new feature, refactor, integration, migration), run a complete planning ritual by orchestrating other skills in sequence: rubber-duck (clarify scope) -> pre-mortem (assess risks) -> eta (estimate time) -> final confirmation. Do not start coding until the battle plan is approved.
git-standards
by joncrangle
This skill should be used when the user asks to "commit changes", "create a PR", "push code", "check git status", or "review git history". Enforces safety checks and conventional commits.
SwiftUI Engineer
by TrevorS
Build, review, debug, and modernize SwiftUI apps for macOS with modern patterns. Use when building SwiftUI UIs, reviewing code quality, debugging view issues, checking anti-patterns, migrating from AppKit, or designing app architecture.
Skill Builder
by TrevorS
Create and validate Agent Skills with proper structure and effective descriptions. Use when building custom skills, testing skill discovery, or designing new skill workflows.
PreventionPatterns
by joncrangle
Known bug patterns and their fixes to prevent regression.
cuda-kernel-refine
by TrevorS
Iterative CUDA kernel optimization using NVIDIA profiling tools (nsys, ncu). Triggers on: "optimize kernel", "refine kernel", "improve throughput", "kernel performance", "make kernel faster", "reduce bandwidth", "memory bound", "compute bound", "roofline", "compare benchmark", "register pressure", "occupancy"
lang-typescript
by joncrangle
This skill should be used when the user asks to "write TypeScript", "debug TypeScript", "create a SolidJS component", "configure TanStack Start", "validate data with Valibot", or mentions .ts/.tsx files. Covers TypeScript 5.9+, SolidJS, and TanStack patterns.
prove-it
by ElliotJLT
Before declaring any task complete, actually verify the outcome. Run the code. Test the fix. Check the output. Claude's training optimizes for plausible-looking output, not verified-correct output. This skill forces the verification step that doesn't come naturally. No victory laps without proof.
WAV Audio Analysis Skill
by TrevorS
Fix: Add output clamping before int16 conversion
just-cli
by joncrangle
This skill should be used when the user asks to "create a justfile", "write just recipes", "configure just settings", "add just modules", "use just attributes", "set up task automation", mentions justfile, just command runner, or task automation with just.
maintaining-claude-code
by TrevorS
Validate and improve Claude Code configurations (CLAUDE.md, skills, commands, hooks). Use when auditing config quality, checking skill discoverability, organizing .claude directory, or deciding which entity type to use.
sanity-check
by ElliotJLT
Before building on assumptions, validates them first. Activates when making claims about how code works, what exists, or why something happens. Prevents assumption cascades where one wrong guess leads to a completely wrong solution.
fan-out
by ElliotJLT
Orchestration pattern for parallelizable tasks. When facing work that can be split into independent subtasks (research multiple topics, analyze multiple files, test multiple scenarios), spawn parallel agents and aggregate results. Use when subtasks have no dependencies on each other.
cosmetic-detect
by deusyu
Analyze facial/body photos to detect signs of cosmetic surgery or aesthetic procedures. Use when the user uploads a photo and asks to identify cosmetic work, detect plastic surgery, assess facial naturalness, check if someone has had work done, analyze before/after photos, or evaluate aesthetic procedure signs. Also trigger when users ask about specific procedures visible in photos (fillers, Botox, rhinoplasty, jaw contouring, etc.), compare photos for surgical changes, or want a "naturalness score" for a face. Works with single images, multiple comparison images, and video screenshots. 触发词：整容检测、看看有没有整、自然度评分、鉴定一下、有没有动过。
lang-javascript
by joncrangle
This skill should be used when the user asks to "write JavaScript", "debug a Node.js/Bun app", "create a Hono server", "configure Biome", "run tests with bun test", or mentions .js/.mjs files. Covers ES2024+, Bun, and Hono patterns.
code-review
by DanielKerridge
Deep code audit that finds dead wiring, silent failures, unfinished features, placeholder stubs, bloated files, and unnecessary complexity. Produces an actionable report with file:line references grouped by severity. Think of it as a senior dev doing a thorough PR review of the entire codebase. Triggers on: "code review", "audit the code", "review the code", "find dead code", "find placeholders", "check for stubs", "prune the code", "code cleanup", "implementation review", "completeness check", "find unused code".
