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.
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.
-
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/
- Project:
-
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.mdin 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
/initto generate aCLAUDE.mdand bootstrap context before working.

Set‑up and enable skills
- Installation: Ensure Node 20+ and Visual Studio Code are installed. Claude Code enhances Claude's coding capabilities with runtime access, terminal support, and code generation.
- Getting Started: Launch Claude Code from VS Code or terminal. Claude Code automatically discovers skills from
.claude/skills/(project) or~/.claude/skills/(user) directories. - Using Skills: Just describe what you need in natural language. Claude Code activates relevant skills automatically based on your request context.
Set‑up and enable skills
- Claude Desktop provides a native application experience for Claude across Windows, macOS, and Linux platforms.
- Access skills through Settings → Capabilities → Skills. Upload custom skills as ZIP files or select from available community skills.
- Desktop app supports all Claude features including file uploads, code generation, and real-time collaboration.
Set‑up and enable skills
- OpenAI's Codex powers GitHub Copilot and can be accessed via CLI tools for code generation and automation.
- While Codex doesn't natively support Anthropic's Skills format, you can adapt skills by including instructions in your prompts or configuration files.
- Best for code completion, refactoring, and generating boilerplate code across multiple programming languages.
Set‑up and enable skills
- Install Node 20+ and then install Gemini CLI via
npm install -g @google/gemini-clior run it on‑demand withnpx @google/gemini-cli. - Run
geminiand sign in with your Google account; a browser window will open for authentication. Gemini CLI currently doesn't have built‑in support for Anthropic skills, but you can follow skill instructions by loading your ownSKILL.mdfile and referencing it in prompts. Use the@symbol to upload files containing your skill instructions.
Set‑up and enable skills
- Install OpenCode with a one‑line script:
curl -fsSL https://opencode.ai/install | bash. - Run
opencode auth loginand choose your provider (e.g., Cerebras) to configure your API key. - Start the interface with
opencodeand initialize your project context using/init. - OpenCode doesn't natively load Anthropic skills, but you can place a
skills/folder in your project and ask OpenCode to read theSKILL.mdfile; this approximates skills functionality and lets you reuse instructions across tools.
Set‑up and enable skills
- Ensure Node 20+ is installed, then install Qwen Code with
npm install -g @qwen-code/qwen-code@latestand verify withqwen --version. Alternatively, clone the repository and install locally. - Start a session by running
qwen. Qwen Code currently doesn't support Anthropic skills directly, but you can still adopt the skill pattern by creating askills/directory and prompting Qwen Code to follow the instructions in yourSKILL.mdfiles.
