Agent Skills Open Standard

WorkflowAdvanced

Agent Skills is an open standard (agentskills.io) for portable skill formats across AI coding agents. Built on Claude Code's SKILL.md, it extends compatibility to Cursor, Windsurf, and other agents. Includes enterprise features like Skills API (/v1/skills), organization-wide deployment, and skill registries.

## Reference: agentskills.io

### What is Agent Skills?
An open standard for portable AI coding agent skills.
Write once, run on any compatible agent (Claude Code, Cursor, Windsurf, etc.)

### Standard SKILL.md (Agent Skills compatible):
```markdown
---
name: deploy-check
description: Verify deployment readiness
version: 1.0.0
compatibility:
  - claude-code
  - cursor
  - windsurf
---

Check deployment readiness:
1. Run test suite
2. Verify environment variables
3. Check dependency versions
4. Validate build output
```

### Skills API:
```bash
# List available skills
GET /v1/skills

# Get skill details
GET /v1/skills/{name}

# Execute a skill
POST /v1/skills/{name}/execute
{
  "arguments": "src/app",
  "context": { "cwd": "/project" }
}
```

### Organization Deployment:
```
org-skills-registry/
  skills/
    deploy-check.md
    security-audit.md
    code-standards.md
  registry.json          # Skill manifest
  README.md
```

### Distribution channels:
1. Project-level: committed to repo
2. Organization: private registry
3. Public: agentskills.io registry
4. npm/pip: package-based distribution

Copy and paste into your CLAUDE.md to start using immediately.

How Agent Skills Open Standard Works

The Agent Skills standard adds version and compatibility metadata to SKILL.md, enabling portable skills across multiple AI coding agents. The Skills API (/v1/skills) provides programmatic skill listing, execution, and management.

When to Use Agent Skills Open Standard

Ideal for organizations using multiple AI coding agents (Claude Code, Cursor, Windsurf) that need unified skills, or for building enterprise-grade skill distribution systems.

Key Strengths

Write-once, run-anywhere cross-platform compatibility
Skills API for programmatic management and CI/CD integration
Centralized skill deployment via organization registries
Open standard (agentskills.io) ensures ecosystem extensibility
