Agent Skills: Portable AI Capabilities

Anthropic released an open standard for packaging agent capabilities: Agent Skills.

The Problem

Every agent platform has its own format. Build for Claude, rebuild for OpenAI, rebuild for local models.

The Solution

Agent Skills are standardized folders:

skill-name/
├── SKILL.md        # Instructions
├── scripts/        # Executable files
├── references/     # Docs
└── assets/         # Resources

Package once. Use anywhere.

What It Enables

• Domain expertise - Legal review, data pipelines as reusable skills
• New capabilities - Presentations, MCP servers, analysis tools
• Repeatable workflows - Consistent, auditable execution
• Interoperability - Same skill across different agents

Why It Matters

Most AI tools chase model performance. Agent Skills chases workflow portability.

The value isn't the LLM. It'''s the work. Skills package that work so it moves with you.

Adoption

Open standard. GitHub repo is public. Growing ecosystem support.
