Claude Skills by ahonn

Create git branches named by conventional-commit type: <type>/<kebab-description>. Use when: creating any new git branch, starting work that needs a branch, or naming a branch. Triggers on: 'create branch', 'new branch', 'branch off', 'checkout -b', '/branch'.

Code quality standards. Defines complexity management, modular design, code smell detection, comment standards. Applied automatically when writing or reviewing code. Invoke directly to clean up comments in a file. Triggers on: 'clean up comments', 'comment cleanup', '/code-quality'.

Create conventional commits. Use when: committing staged changes. Triggers on: '/commit', 'conventional commit'.

Toggle English-only mode. Forces English input and provides grammar feedback. Use when: '/english', 'english mode', 'toggle english'.

Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks "what could be animated here?" or wants to "make this feel more alive". For fixing existing animations, use improve-animations or review-animations instead.

Compact the current conversation into a handoff document for another agent to pick up.

Systematic root-cause debugging. Use when: diagnosing bugs, investigating failures, debugging flaky tests, tracing unexpected behavior. Triggers on: '/investigate', 'debug this', 'why is this failing', 'find the root cause', 'flaky test'.

iOS app design guidelines based on Apple HIG and iOS 26 Liquid Glass. Use when: (1) Designing iOS app interfaces, (2) Reviewing iOS UI code, (3) Building SwiftUI/UIKit views, (4) Adopting Liquid Glass design, (5) Creating app icons. Triggers on: iOS design, SwiftUI layout, tab bar, navigation bar, Liquid Glass, SF Symbols, Dynamic Type, safe area, app icon, HIG.

nix-darwin dotfiles configuration for macOS with Nix flakes and home-manager. Use when: adding/modifying programs, writing nix modules, editing host configs (workstation/homelab), debugging darwin-rebuild errors, managing homebrew packages via nix, or improving nix architecture.

Enforce a strict ban on direct useEffect calls in React code. Replace with derived state, event handlers, data-fetching libraries, useMountEffect, or key-based remounting. Use when: (1) Writing new React components, (2) Reviewing React code for effect usage, (3) Refactoring existing useEffect calls, (4) AI agent is about to add useEffect. Triggers on: useEffect, effect hook, side effect, sync state, dependency array, infinite loop, race condition, effect cleanup.

Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.

React best practices from react.dev and Vercel. Use when: (1) Reviewing React code, (2) Debugging performance issues, (3) Optimizing bundle size, (4) Writing effects or state logic. Triggers on: React performance, re-render, bundle size, waterfalls, code splitting, memo, useCallback, useMemo, useEffect, SSR flicker, initial load slow, React Compiler, state structure, immutable update, setState array object.

Reviews animation and motion code against a high craft bar derived from Emil Kowalski's design engineering philosophy. Default to flagging; approval is earned.

Rust idioms and design patterns for writing idiomatic code. Use when: (1) Writing new Rust code, (2) Reviewing Rust code, (3) Solving borrow checker issues, (4) Designing Rust APIs. Triggers on: Rust ownership problems, lifetime errors, API design questions, 'how to do X idiomatically in Rust'.

Self-review of code changes (branch diff, staged, or uncommitted). Use when: reviewing code before pushing, checking diff quality, self-reviewing a PR, creating a PR (always use --peer), reviewing uncommitted work. Triggers on: '/self-review', 'review my changes', 'review this branch', 'self-review', 'pre-push review', 'review uncommitted', 'review staged', 'create PR', 'open PR', 'submit PR'.

Advanced full SEO audit skill. Runs its own full workflow from local scripts, including the basic SEO checks plus PageSpeed, social metadata, and advanced review modules when available.

An SEO agent skill for quick, lightweight, default single-page SEO audits. Performs basic on-page and site-level checks and outputs a structured basic SEO audit report. Use when the user asks for "SEO audit", "SEO check", "check my page SEO", "page analysis", or wants a first-pass review of a URL. If the user requests "deep audit", "full report", "technical SEO audit", or "advanced SEO", use seo-audit-full instead.

Guide for creating Claude skills. Use when: creating or updating skills. Triggers on: 'create skill', 'new skill', 'skill template'.

Research → Plan → Code workflow. Enforces evidence-based reasoning, codebase research, and structured planning before code modifications. Applied automatically for moderate+ tasks.

Red-green test-first workflow for behavior with a clear, user-confirmed seam. Use when: user asks for TDD/test-first/red-green, adding non-trivial domain logic with an existing test harness, or fixing a bug that needs a regression test under mode tdd. Do NOT use when: config/docs/Nix/home-manager only, pure styling/copy, renames, scaffolding, prototypes, no test runner for this surface, user said skip tests, verification is build/flake-check only, or AGENTS test mode is skip|verify-only|add-t...
