Skill Test

A simple test skill to verify that the Claude Agent SDK skills system is functioning correctly.

Purpose

This skill exists purely for testing. When invoked, it returns a simple JSON response to confirm:

  1. Skills are being discovered from .claude/skills/ directory
  2. The SDK can invoke project-level skills
  3. JSON responses are properly parsed

When to Use

Use this skill when:

  • Asked to "test skills"
  • Asked to "verify skills work"
  • Asked to "run a skill test"
  • Testing the skills system

What This Skill Does

Simply returns a JSON response with:

  • A success flag
  • A timestamp
  • A greeting message
  • The skill version

Output Format

Return ONLY valid JSON. No markdown code fences, no explanation.

{
  "success": true,
  "message": "Skill system is working!",
  "timestamp": "<current ISO timestamp>",
  "version": "1.0.0",
  "test_data": {
    "skill_name": "skill-test",
    "invocation_count": 1
  }
}

Example Response

{
  "success": true,
  "message": "Skill system is working!",
  "timestamp": "2025-10-24T12:34:56.789Z",
  "version": "1.0.0",
  "test_data": {
    "skill_name": "skill-test",
    "invocation_count": 1
  }
}

That's it! This skill should be trivial to invoke and verify.
