28 Claude Tools to Install Right Now

Takes any AI-generated text and rewrites it to sound like a real person wrote it. It scans for 24+ common AI writing patterns (overuse of em dashes, perfectly balanced paragraphs, robotic transitions) and strips them out. You can feed it samples of your own writing so it matches your personal voice and sentence rhythm.

Ultra-compressed communication mode that cuts Claude's token usage by roughly 75%. It drops filler words, articles, and pleasantries while keeping full technical accuracy. This saves you money on API usage and keeps responses fast and scannable. Over 438,000 installs and 98,000+ GitHub stars make it one of the most popular Claude skills in existence.

Anthropic's official skill for building your own custom skills. It walks you through an interactive Q&A process and generates a properly structured SKILL.md file. Instead of learning the format yourself, you describe what you want the skill to do and it produces the complete package. This is how you turn any repeatable workflow into a one-command operation.

The built-in skill discovery system inside Claude Code and Claude Desktop. Use the /plugin command to browse the Discover tab, search by keyword, and install any skill from the official or community marketplaces. In Claude.ai, you can type /anthropic-skills: followed by a skill name to invoke built-in Anthropic skills directly. Think of it as the app store for Claude capabilities.

Fixes the biggest problem with AI-generated UIs: they all look the same. This skill forces Claude to commit to a bold, distinctive design direction before writing any code. It bans overused fonts like Inter and Roboto, requires a design system to be established upfront, and produces output that looks like it was built by a designer, not a chatbot. Over 277,000 installs. Works with React, Vue, Svelte, and vanilla HTML.

A comprehensive SEO audit and optimization skill with 25 sub-skills, 18 specialist agents, and 8 optional extensions. Covers technical SEO, E-E-A-T, schema markup, GEO (generative engine optimization), AEO (answer engine optimization), backlink analysis, local SEO, and semantic clustering. Run a single command to get a full audit with evidence-backed findings and a prioritized action plan. Free, open source, and MIT licensed.

An open-source video rendering framework from HeyGen that turns HTML, CSS, and JavaScript into rendered MP4 videos. Instead of using a timeline editor, you describe what you want and Claude writes the code for motion graphics, explainer videos, product launches, animated slides, and social clips. Ships with 20 agent skills covering workflows from "website to video" to "PR to video." Works as both a Claude connector and a Claude Code skill.

Creates complex, multi-component HTML artifacts using React, Tailwind CSS, and shadcn/ui. While Claude can build simple artifacts by default, this skill handles the heavy lifting: state management, routing, component composition, and bundling everything into a single portable file. Use it for interactive dashboards, calculators, forms, games, and any web app that goes beyond a static page.

A complete software development workflow skill pack. It enforces a plan-first, test-driven execution cycle: think before you code, write tests first (Red, Green, Refactor), then run a cold-read review. Widely used by individual developers, startups, and engineering teams. Pairs well with G-Stack for decision-making and GSD for spec management. This is the "execution layer" of the most popular Claude Code skill stacks.

Open-source skill pack created by Y Combinator CEO Garry Tan. Turns a single Claude Code instance into a virtual engineering team with 9+ specialist roles: a CEO who reviews product decisions, an engineering manager for architecture, a designer who catches AI slop in UIs, a security reviewer, a QA lead that opens a real browser and tests your app, and a release manager for git workflows. Over 85,000 GitHub stars within weeks of release. Garry Tan publicly shared that he averaged 10,000 lines of code and 100 pull requests per week using this stack.

Delegates coding tasks to OpenAI's Codex CLI, running in a completely separate process from Claude. This gives you a second AI model reviewing your code from a different perspective. Adds /codex:review, /codex:adversarial-review, and /codex:rescue commands. Fire off a code review to Codex, keep working with Claude in the foreground, and check results when done. Every AI model has blind spots; running two eliminates more of them.

Guides Claude through building high-quality MCP (Model Context Protocol) servers in Python or TypeScript. MCP is the open standard that powers how Claude connects to external services. This skill handles tool definitions, schemas, and transport wiring so you can hook Claude up to any API or database. If the connector you need does not exist yet, this is how you build it yourself.

Read, search, draft, reply, and send emails. Claude can triage your inbox, draft personalized responses, find specific email threads, and create follow-up sequences. Emails send with your approval, never automatically. Pairs powerfully with other connectors: "Read the client brief from Gmail, create tasks in Asana, and send a kickoff message on Slack."

View and manage your calendar events. Claude can check your schedule, identify conflicts, suggest meeting times, and create events. Useful for morning briefings: "What does my day look like? Flag any back-to-backs and suggest a 15-minute buffer."
