Getting Started with Agent Skills đź§
Adding skills to your AI workflow is simple. In just a few minutes, you can enhance your agent's capabilities for specific tasks across multiple platforms.
Works Across Platforms
Agent Skills is an open standard. The same skill file works with Claude, OpenAI Codex, GitHub Copilot, VS Code, and more. Write once, use everywhere.
Platform-Specific Instructions
While skills are universal, installation paths differ by platform. For detailed setup instructions for your specific tool, see our Supported Platforms guide.
Prerequisites
To use skills, you need:
- Access to an AI agent that supports the Agent Skills specification (Claude, OpenAI Codex, GitHub Copilot, VS Code)
- Access to your preferred agent interface (web, IDE, or API)
Best Experience
Skills work best with persistent context features. Most platforms offer this: Claude Projects, Copilot Custom Instructions, Codex skills directory, etc. These let you add knowledge that applies across all conversations in that context.
Step 1: Find a Skill
Browse our skill directory to find skills that match your needs. You can:
- Search by keyword using the search bar
- Browse by category (Development, Document Creation, etc.)
- Filter by official vs community skills
Step 2: View the Skill
Click on any skill to see its full details, including:
- What the skill does
- Who created it
- Links to the SKILL.md file
Step 3: Copy the Skill
On the skill page, click "View SKILL.md" to open the full skill definition. Then:
- Click the copy button or select all the content
- Copy the entire SKILL.md content to your clipboard
Remember: The same SKILL.md file works across all platforms. Copy it once, and you can use it with any AI tool that supports the Agent Skills specification.
Step 4: Add to Your Platform
For Claude:
- Go to claude.ai and open or create a Project
- Click on Project Knowledge in the sidebar
- Click Add Content → Add text
- Paste the skill content
- Give it a descriptive name (e.g., "Excel Creator Skill")
- Click Save
For GitHub Copilot (as of December 2025):
- Create a
.github/skills/directory in your project - Create a subdirectory for your skill (e.g.,
.github/skills/excel-creator/) - Create a
SKILL.mdfile in that directory - Paste the skill content into
SKILL.md - Save the file—Copilot will automatically load it
Note: .claude/skills/ directory is also supported
For Other Platforms:
- Check our Supported Platforms guide for specific instructions
- Or look for "System Instructions", "Custom Instructions", or "Knowledge" settings in your tool
- Paste the skill content into the appropriate location
- Save your changes
That's It!
The skill is now active. Start a new conversation and the agent will automatically use the skill when relevant to your requests.
Tips for Best Results
Use Specific Projects or Contexts
Create dedicated projects or contexts for different types of work. Add only the relevant skills to each context to keep the agent focused and avoid context overload. This works the same across all platforms.
Combine Skills Thoughtfully
You can add multiple skills to a context, but be mindful of how they interact. Skills that complement each other (like "Frontend Design" + "Artifacts Builder") work great together.
Test Before Relying
After adding a skill, test it with a few typical requests to ensure it works as expected for your use case and platform.
Use Skills Across Platforms
Because skills follow an open standard, you can copy the same skill to multiple platforms. Use it with Claude for web work, Copilot for coding in VS Code, and Codex for CLI workflows—all with the same SKILL.md file.
Check for Updates
Skills may be updated over time. Periodically check back to see if there are improved versions available.
Troubleshooting
Skill doesn't seem to be working
- Make sure you're in the right project or context where the skill was added
- Start a new conversation (skills apply to new chats on most platforms)
- Check that the skill was saved properly to your platform's knowledge base
- Verify the skill format is correct (valid YAML frontmatter and markdown)
The agent ignores the skill
- Try explicitly mentioning what you want (e.g., "Create an Excel spreadsheet for...")
- The skill may only activate for specific types of requests—check the skill's description
- Some platforms require specific triggers or commands to activate skills
Installation path issues
- Each platform uses different installation paths—see our Supported Platforms guide for exact paths
- Make sure the SKILL.md file is properly named (case-sensitive on some systems)
- Check that the file is in the correct directory structure for your platform
