Best Claude skills for refactoring in 2026

A comprehensive autonomous web research agent that performs targeted searches, fetches and parses web content, summarizes findings, and generates structured reports, adhering to industry best practices for accuracy, security, and robustness.

Zero to power user in one invoke — detects OS, installs Homebrew/apt/Node.js/Python, sets up Claude Code, authenticates skills-hub CLI, connects MCP servers, and installs recommended skills based on your project. Cross-platform (macOS, Linux, WSL). Idempotent. Use when: 'quickstart', 'setup machine', 'new machine setup', 'install everything', 'get started', 'onboard me', 'setup skills-hub', 'fresh install'.

Multi-pass editor that removes AI-writing tells from drafted content — eliminates filler phrases, balances sentence length, restores opinion and voice, and strips em-dash overuse so posts sound human and opinionated rather than ChatGPT-generic. Use when the user wants to humanize AI-generated marketing copy, blog posts, landing pages, or social content.

Reconstructs the development cycle from git history, distills sequential/parallel patterns, and produces actionable insights for improving future iterations. Triggers: recall, retrospective, development analysis, what happened, dev cycle analysis.

Verify your development environment is correctly configured for a project — checks runtime versions, dependencies, env vars, services, ports, and permissions.

A comprehensive social media automation skill that monitors platforms like Reddit and other social media sites to generate, post, and reply with relevant content promoting your app. It ensures content relevance, adheres to platform policies, and incorporates best practices for engagement and safety.

Auto-detects the current project's technology stack and hot-loads context-appropriate skills at session start using Claude Code's SessionStart hook with reloadSkills: true. Detects Node.js/TypeScript, Next.js, Python, Rust, Go, Ruby, and monorepo layouts. Emits a .claude/dynamic-context.md with the detected stack and recommended skill list, then signals Claude Code to reload skills before the first agent turn.

Persist, summarize, and reload agent context between sessions — writes a structured session log to CLAUDE.md / AGENTS.md / .hermes.md, snapshots decisions before destructive ops, and resumes long-running goals without re-briefing. Works with any coding agent.

Generate MLS-compliant property listing copy in five length variants (tagline, MLS-short ≤250 char, MLS-long ≤4000 char, marketing description ~600-800 words, social caption) PLUS schema.org RealEstateListing JSON-LD for SEO/AEO syndication. Auto-runs HUD Fair Housing Act compliance check (catches discriminatory language patterns — "perfect for families", "walking distance", "exclusive", "safe neighborhood", "Christian community", etc.). TRIGGER on phrases like "MLS listing", "property listing description", "listing copy", "real estate description", "Zillow listing", "compelling listing", "write the listing", "MLS remarks", "marketing copy for [property]", "open house copy". Saves agents 30-60 minutes per listing — and prevents the fair-housing violations that cost agents licenses.

Analyzes mobile app binary size -- asset audit for unused images and font subsetting, code stripping with ProGuard and tree-shaking, on-demand resources, dynamic feature modules, and app thinning strategies. USE THIS SKILL WHEN: - Your app's download size is too large or growing unexpectedly - Someone asks "why is our app so big?" or "how do we reduce app size?" - You need to audit assets (images, fonts, videos) for waste or optimization - App store reviewers flag your app for exceeding cellular download limits (200MB) - You want to check if ProGuard/R8, tree-shaking, or resource shrinking is properly configured - Someone mentions ABI splits, dynamic feature modules, or on-demand resources - You are preparing for a release and want to minimize download size - Users are complaining about storage space or download times - You need to audit dependencies for size bloat or lighter alternatives TRIGGER PHRASES: "app size", "binary size", "reduce app size", "APK size", "IPA size", "unused ass
