Awesome LLM Skills
A curated list of awesome LLM Skills, resources, and tools for customizing AI workflows on tools like Claude Code, Codex, Gemini CLI, Qwen Code, OpenCode etc.

What Are LLM Skills?
LLM Skills are customizable workflows that teach LLM how to perform specific tasks according to your unique requirements. Skills enable LLM to execute tasks in a repeatable, standardized manner across all LLM platforms.
Quick Start
-
Create a project-local or user-level skill folder
Use one of these discovery paths so Claude Code finds it automatically:
- Project:
.claude/skills/webapp-testing/
- User:
~/.claude/skills/webapp-testing/
-
Add SKILL.md (required)
Basic Skill Template:
---
name: my-skill-name
description: A clear description of what this skill does and when to use it.
---
# My Skill Name
Detailed description of the skill's purpose and capabilities.
## When to Use This Skill
- Use case 1
- Use case 2
- Use case 3
## Instructions
[Detailed instructions for LLMs on how to execute this skill]
## Examples
[Real-world examples showing the skill in action]
- Focus on specific, repeatable tasks
- Include clear examples and edge cases
- Write instructions for LLM, not end users
- Document prerequisites and dependencies
- Include error handling guidance
-
Keep supporting files small
Add only what's needed (e.g., small fixtures in resources/, helper scripts). This keeps skills snappy to load and easier for Claude to apply.
-
Load the skill
- Claude (web or Desktop): Upload a ZIP via Settings → Capabilities → Skills → Upload skill.
- Claude Code (terminal): Place the folder under
.claude/skills/ (project) or ~/.claude/skills/ (user). Claude Code discovers skills from these locations.
- Other CLIs (Codex, Gemini, OpenCode, Qwen Code): They don't use Anthropic's Skills format natively—reference your
SKILL.md in prompts (Gemini CLI supports @ file/context attachments).
-
Use it
Just ask in natural language, optionally mentioning the skill by name—for example:
"Use the Webapp Testing skill to validate the checkout flow and generate report.md." Claude can auto-invoke relevant skills based on your request.
-
(Optional) Kickstart a repo session in Claude Code
Slash-commands are supported; many users run /init to generate a CLAUDE.md and bootstrap context before working.
