# Skill Name

Detailed description of the skill's purpose.

## When to Use This Skill

- Use case 1
- Use case 2

## Instructions

[Detailed instructions for the agent]

## Examples

[Real-world examples]

Best Practices

Keep descriptions exhaustive: The frontmatter description helps agents decide when to trigger the skill.
Focus on execution: The body should contain clear, actionable steps.
Use progressive disclosure: Put detailed references in references/ folder.
Include scripts for automation: Use helper scripts for deterministic operations.
Keep SKILL.md under 500 lines: For optimal performance.
Test across platforms: Verify skills work with Claude Code, Codex, etc.

Token Efficiency

Skills employ progressive disclosure architecture:

Metadata loading (~100 tokens): Agent scans available skills
Full instructions (<5k tokens): Load when skill is activated
Bundled resources: Only load as needed

Platform-Specific Paths

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.

# Skill Name

Detailed description of the skill's purpose.

## When to Use This Skill

- Use case 1
- Use case 2

## Instructions

[Detailed instructions for the agent]

## Examples

[Real-world examples]

Best Practices

Keep descriptions exhaustive: The frontmatter description helps agents decide when to trigger the skill.
Focus on execution: The body should contain clear, actionable steps.
Use progressive disclosure: Put detailed references in references/ folder.
Include scripts for automation: Use helper scripts for deterministic operations.
Keep SKILL.md under 500 lines: For optimal performance.
Test across platforms: Verify skills work with Claude Code, Codex, etc.

Token Efficiency

Skills employ progressive disclosure architecture:

Metadata loading (~100 tokens): Agent scans available skills
Full instructions (<5k tokens): Load when skill is activated
Bundled resources: Only load as needed

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
