35 Claude Code Skills — Here's What's Actually Useful

This week: a deep batch of open-source skills for Claude Code (and a few for Cursor). Lots of noise, but about a dozen are genuinely worth your time.

The Big Idea

The "Claude skills" ecosystem is maturing fast — think of these as .md files or CLI tools that snap specialized behavior onto your AI coding agent. The best ones replace a SaaS subscription or a consultant. The worst ones are just novelty prompts. Below is the edited highlight reel.

AI Agent Tooling: Build Better, Faster

talk-normal

A system prompt that kills corporate-speak in LLM responses — no more "Certainly! Great question!" preamble before every answer. Drop it into your Claude or ChatGPT setup and get direct, informative replies instead. Small change, big quality-of-life improvement.

harness

A meta-skill that spins up entire AI agent teams — it defines specialized agents, assigns them roles, and generates the coordination logic between them. If you're building multi-agent workflows manually right now, this automates the scaffolding. Worth a look before you hand-roll another orchestration layer.

autoskills

A CLI that scans your project's tech stack and auto-installs the best matching skills from the skills.sh registry. Detects Next.js, Tailwind, Spring Boot, etc. and wires up relevant agent skills without manual configuration. Useful starting point for any new project where you want Claude Code actually aware of your stack.

SkillClaw

An "agentic evolver" that watches your AI agent's sessions and automatically refines its skills from real interaction data — deduplicating, improving, and verifying them over time. Agents that improve themselves from usage, rather than needing constant manual prompt rewrites, is the right direction. Early, but the concept is solid.

Self-Hosted Alternatives to Expensive SaaS

email-campaigns-claude

An autonomous email agent that connects Claude Code to the Resend API to draft copy, build HTML layouts, optimize subject lines, and fire bulk sends — all from the terminal. Replaces Mailchimp, ConvertKit, and similar subscription tools for teams that can handle a little CLI. If your email marketing budget is going to a SaaS platform and you have a developer, this is worth evaluating.

shopify-admin-skills

63 AI agent skills for operating a Shopify store: abandoned cart recovery, bulk price adjustments, inventory audits, refund processing. Replaces a pile of Shopify apps and a lot of manual admin clicking. Shopify store owners with a dev on hand should look at this before renewing another third-party app subscription.

Dev Productivity: Design, Docs & Code Quality

skillui

A CLI that reverse-engineers any website, GitHub repo, or local project into a Claude-ready design skill — extracting design tokens, fonts, and hex colors. No API keys needed. Saves hours when you need to match an existing brand or replicate a design system from a live site.

hue

Similar angle to skillui but focused on brand: point it at a URL, name, or screenshot and it generates a full reusable design system with color tokens, typography, and light/dark mode variants. Replaces the manual process of documenting brand guidelines before feeding them to an AI. If you're doing client work, this is a real time-saver.

my-ai-workflow

A battle-tested workflow that forces Claude to interview you, explore the codebase, and ask hard architectural questions before writing a single line of code. Prevents the "AI just started coding without understanding the problem" failure mode that wastes hours. If you're using Claude Code without a structured planning gate, this is a good starting template.

spider-king-skill

A reverse-engineering skill that turns modern, anti-bot-protected websites into clean protocol-level Python collectors — bypassing DOM noise and browser dependencies. Replaces fragile Beautiful Soup / Scrapy setups for sites that actively fight scraping. Practical for anyone pulling structured data from hostile web clients.

Niche But Notable

friday-showcase

A fully autonomous, self-evolving AI assistant built on Claude Code CLI + Telegram — manages tasks, monitors info, and learns from its own behavior over time. No custom AI backend or fine-tuning required. Ambitious scope; replaces a personal assistant + task manager + a handful of automation tools if you're willing to run it yourself.

buffett-skills

Distills Warren Buffett's value investing framework into a Claude Code skill that runs structured financial analysis on stocks — economic moat, management quality, valuation, capital allocation. Skeptic's note: AI + stock picking deserves a healthy side-eye, but as a research organizer rather than a decision-maker, this is genuinely useful.

Quick Hits

• caveman-claude-skill — Forces Claude to respond like a caveman: terse, no filler, full technical accuracy. Claims up to 75% token reduction. Sounds absurd; actually useful for cutting API costs on high-volume workflows.
• marp-slides — Turns Claude into a MARP deck designer with SVG charts and themes, all in Markdown. Replaces PowerPoint/Google Slides for devs who live in the terminal.
• html-ppt-skill — Similar idea, HTML-native: 36 themes, 31 layouts, 20+ animations, presenter mode included. Two solid presentation options; pick your flavor.
• agentic-seo — Audits docs and websites for AI agent discoverability, not Google. Think Lighthouse but for LLM crawlers. From Addy Osmani, so the code quality bar is high.
• PaperOrchestra — Multi-agent pipeline that turns research notes into submission-ready LaTeX papers, complete with simulated peer review. Niche, but researchers will want to bookmark this.
• android-skills-mcp — Wraps Google's official android-skills library as an MCP server and converts skills into native rule formats for seven different AI agents. Android devs using multiple AI tools should check this one.
• antivibe — Explains why AI wrote the code it wrote, maps concepts, and links learning resources. Directly addresses the "vibe coding without understanding" problem — useful for devs who want to actually grow, not just ship.

The Takeaway

Pick one: install talk-normal into your Claude setup today — it takes five minutes and immediately improves every AI interaction you have. If you're a Shopify merchant, open shopify-admin-skills and count how many of those 63 skills overlap with apps you're currently paying for.

Reply and let me know which of these would actually be useful in your workflow — or if there's a category of Claude skills you want us to dig into next issue.
