October 17, 2025 -

Hey everyone.

I have compiled a curated list of all known Claude Skills (both official ones from Anthropic and community-built projects found across GitHub).

Each skill has a clear description and a link to its repository, so you can plug them directly into your Claude setup or use them as templates to create your own.

r/ClaudeAI on Reddit: I’ve been tracking what people are building with Claude Skills since launch - here’s the wildest stuff I’ve found (with links)
October 20, 2025 -

So Claude Skills dropped last week and honestly, I’ve been down a rabbit hole watching what the community’s been shipping. For those who haven’t tried it yet - Skills are basically persistent instructions/code/resources that Claude can load when it needs them. Once you install a Skill, Claude just knows how to do that thing across all your conversations.

The crazy part? People are building genuinely useful stuff in HOURS, not weeks.

Here’s what I’ve found so far:

🔥 The Meta One: Skill-Creator

Anthropic made a Skill that builds Skills for you. Yeah, you read that right. You just describe what you want in plain English, and it writes the SKILL.md file for you. I tested it yesterday and it’s actually really good. Demo (47 seconds): https://youtube.com/watch?v=kS1MJFZWMq4

🤖 Auto-Generation Tool: Skill Seekers

u/Critical-Pea-8782 built something wild - a tool that auto-generates Claude Skills from ANY documentation site.

  • Feed it a docs URL

  • Wait 25 minutes

  • Get a production-ready Skill

It has presets for React, Vue, Django, Godot, FastAPI… basically any major framework. GitHub: https://github.com/yusufkaraaslan/Skill_Seekers I tried this with the Godot docs and it actually works. The Skill it generated knows way more about Godot than base Claude.

📚 Community Collections

A few people have started curating all the Skills being created:

BehiSecc’s Collection: https://github.com/BehiSecc/awesome-claude-skills Includes: CSV analyzers, research assistants, YouTube transcript fetchers, EPUB parsers, git automation, and a bunch more.

travisvn’s Collection: https://github.com/travisvn/awesome-claude-skills Similar vibe but with more enterprise/workflow focus. Both are actively maintained and honestly just browsing these gives you ideas.

🎨 Official Anthropic Skills Pack

Anthropic shipped 15 Skills out of the gate. The document creation ones are actually really impressive:

  • docx - Creates proper Word docs (not just markdown pretending to be Word)

  • pptx - Actual PowerPoint files with layouts, charts, etc.

  • xlsx - Excel with real formulas

  • pdf - Form filling and manipulation

  • canvas-design - Visual layouts in PNG/PDF

  • brand-guidelines - Keeps everything on-brand

  • algorithmic-art - Generative art with p5.js

  • slack-gif-creator - Makes GIFs that fit Slack’s constraints

Plus more for internal comms, web testing, MCP server creation, etc. GitHub: https://github.com/anthropics/skills The document-skills folder is particularly interesting if you want to see how Anthropic approaches complex Skills.

🧠 Simon Willison’s Take: “Bigger Than MCP”

Simon Willison (the guy who reverse-engineered Skills before the official announcement) wrote a really good technical breakdown: https://simonwillison.net/2025/Oct/16/claude-skills/

TLDR: Skills are more token-efficient than MCP and way easier to share. Each Skill only uses a few dozen tokens until it’s actually needed, then Claude loads the full details. His take is that Skills might end up being more important than MCP in the long run. Honestly? After using both, I kinda see his point.

🎬 Official Demo: Skills Chaining

Anthropic’s demo shows Skills working together automatically: PowerPoint Skill → Brand Guidelines Skill → Poster Design Skill All in one conversation. Claude just switches between them as needed. Video: https://youtube.com/watch?v=IoqpBKrNaZI

🤔 My Honest Take

I’ve been using Claude for months and Skills genuinely feel different. It’s not just “better prompts” - it’s more like giving Claude actual expertise that sticks around. The best part? Everything’s open-source. You can fork Skills, modify them, share them with your team. The barrier to entry is super low.

Downsides I’ve noticed:

  • Some Skills work better than others (canvas-design got roasted on HN)

  • You need Claude Pro/Team/Enterprise (not available on free tier)

  • It’s still early - some rough edges But overall? This feels like a real step forward in making AI actually useful for specific workflows.

📢 What are you building?

Has anyone else been experimenting with Skills? What have you built? What Skills do you wish existed? I’m particularly curious if anyone’s made Skills for:

  • API documentation (specific to your company)

  • Data analysis workflows

  • Content creation pipelines

  • Design systems
