Revolutionary System for Customizing AI Capabilities
On October 16, 2025, Anthropic announced Skills for Claude, a new system that allows the AI to load task-specific instructions, scripts, and resources when needed. Skills are folders containing instructions and resources that Claude can access only when relevant to the task at hand, improving efficiency and accuracy for specialized workflows.
ðŊ How Skills Work:
- âĒ Composable: Skills stack together - Claude identifies needed skills and coordinates their use
- âĒ Portable: Use same format across Claude apps, Claude Code, and API
- âĒ Efficient: Progressive disclosure - Claude sees skill names/descriptions, loads only what's needed
- âĒ File Structure: Folder with required SKILL.md file + optional referenced files
- âĒ API Limits: Up to 8 skills per request, 8MB combined upload, YAML frontmatter required
ð§ Availability: Skills are available to Pro, Max, Team, and Enterprise users. Free tier is not included. Anthropic provides starter Skills for creating Excel spreadsheets, PowerPoint presentations, documents, and fillable PDFs. Users can create custom Skills for brand guidelines and specialized workflows.
This launch positions Anthropic as a leader in customizable enterprise AI, directly competing with OpenAI's GPTs and Google's custom AI agents while maintaining consistency across all Claude platforms.
