Agent Army

Deploy a 2-layer parallel agent hierarchy for large, parallelizable work — big refactors, multi-file migrations, codebase-wide audits, bulk generation. A top-tier commander (Fable or Opus) orchestrates the swarms; the user picks a power level (Max Power / Heavy / Balanced / Economy) that sets the Opus/Sonnet/Haiku model mix per layer. Layer 1 is 3-50+ specialist agents, each with its own full context window; Layer 2 is 2+ sub-agents per member. Includes git safety, tiered sizing, a pre-deploy gate, phantom-completion checks, and multi-wave follow-up.

Design Export Repair

Fixes broken decks/PDFs exported from Claude's \"Design\" feature (or similar AI deck generators) — cut-off or clipped text, wrong/substituted fonts, and corrupted .pptx package structure that shows up only once you export to PDF, not while looking at it in the app. Use this skill whenever the user uploads a zip, .pptx, or .pdf exported from Claude Design (or mentions \"Design\" export, an AI-generated deck, or a generated slide deck/PDF) AND reports it looking broken, wrong, cut off, garbled, or different from the original when opened, printed, or converted to PDF — even if they don't use the word \"repair\" or name the specific defect. Also trigger for general \"my exported PDF/deck is broken, help fix it\" requests when the file was clearly produced by an AI design/deck tool rather than hand-authored. Produces both a repaired, still-editable .pptx and a clean PDF, plus a report of exactly what was wrong and what changed.

Css Animation Creator

Create professional CSS animations, transitions, micro-interactions, and complex motion design. Use when adding animations, hover effects, loading states, page transitions, scroll animations, or any motion design work.

Dark Mode Converter

Convert a light-only site or app to a real dark mode -- semantic token mapping, elevation-based surfaces, recalibrated shadows and imagery -- not a naive inversion. Handles Tailwind, CSS variables, and styled-components, plus the toggle, persistence, and no-flash boot.

AI Agents

Agent Army

Agent Swarm Deployer

Deploys swarms of sub-agents for massive parallel data processing tasks.

Scout

Analyzes current conversation context to recommend the best skills and subagents for the task at hand. Use proactively when unsure which tool, skill, or agent to use.

Scout Pro

Enhanced skill navigator that maps conversation history, recommends multi-skill chains, identifies patterns from past usage, and learns from session outcomes. Goes beyond basic scout with deep context analysis and workflow orchestration.

Claude Products

Claude Design Critic

Audit a website or UI and de-AI it — find the patterns that make it look template-generated (in both design and copy) and return specific, prioritized fixes that push it toward editorial, premium, human-crafted. Reviews layout, color, type, spacing, motion, accessibility, AND the words. Use after building or generating any frontend, or when a site looks "fine but generic" and you can't say why.

Claude Design System Architect

Generate a complete, premium design system from a brand brief or an existing site — color tokens, type scale, spacing/radius/elevation, motion language, and component specs — exported as Tailwind config, CSS variables, and a usage doc. Built to look editorial and human-crafted, not template-generated. Use when starting a new product/site, unifying an inconsistent UI, or codifying a brand into reusable tokens.

Claude Landing Composer

Compose a premium, animated landing page section by section in Next.js + Tailwind + Motion (Framer Motion) — built on a real design system, with editorial copy and motion that feels human-crafted, not template-generated.

Get the whole library

Claude Code loads every folder containing a SKILL.md and ignores the rest. If ~/.claude/skills already exists, clone elsewhere and symlink the folders you want — Claude Code follows symlinks.

Install all skills

git clone https://github.com/OneWave-AI/claude-skills.git ~/.claude/skills

Update later

git -C ~/.claude/skills pull

The skills are free. The rollout is the hard part.

Teams that get real value out of Claude don't just install skills — they change how the work gets done. That's what we do: in-person and virtual training, bootcamps, and builds on your actual workflows.

Questions

What is a Claude skill?

A skill is a folder with a SKILL.md file that teaches Claude how to do a specific job — the instructions, the steps, and any reference files it needs. Claude loads it when a task matches its description. Skills are instructions; MCP servers are connections to external tools; plugins bundle both. Most of what people want is a skill.

Where do skills go on my machine?

Personal skills live in ~/.claude/skills/<skill-name>/SKILL.md, and project-specific ones in .claude/skills/ inside the project. The folder name is the skill name. Claude Code watches those directories, so a new skill works immediately — no restart.

Do these work in Claude Cowork and the Claude app?

Most of them. Cowork and the Claude app do not read your local ~/.claude/skills/ folder — they load skills enabled on your account, uploaded as a zip. Every skill page here has a zip download and the upload steps. Skills that run shell commands or spawn agents are Claude Code only, and each one says so.

Can I use these commercially?

Yes. The library is MIT licensed. Use them at work, modify them, ship them inside your own tooling. No attribution required and no email wall.

Who maintains this?

OneWave AI. We are an AI consultancy — we train teams on Claude and build AI tools for companies from SMB to enterprise. These are the skills we actually use on client work, opened up.

Also on 12 independent directories

Other people index and redistribute these skills — 50K+ downloads reported across the directories below. On GitHub, where we can measure it directly, the library has 272 stars, 42 forks, and was.

Elsewhere

Anthropic publishes its own official skills — document handling (pptx, docx, xlsx, pdf), artifact building, and skill authoring among them. They follow the same open format as everything here and work alongside these.
