If there are no prerequisites, remove this section.

[Detailed instructions for the first step. Use imperative form (commands).]

• Check that [prerequisite] is available
• Verify [condition] is met
• Gather [required information]

Example:

# Command to verify setup
tool --version

# Command to check prerequisites
tool check --all

[Instructions for the primary workflow.]

1. Execute [specific action]
2. Monitor [specific indicator]
3. Validate [expected condition]

Important Considerations:

• [Key decision point or branching logic]
• [Edge case to handle]
• [Safety check or validation]

Example:

# Example code showing this step
def main_process():
    """Core implementation of the skill's main action."""
    # Step-by-step implementation
    result = perform_action()
    validate(result)
    return result

[Instructions for confirming success.]

Verify the process completed successfully by:

1. Checking [specific output or indicator]
2. Confirming [expected state or condition]
3. Running [validation command or test]

Expected Outcomes:

• [Specific success criterion 1]
• [Specific success criterion 2]

Example:

# Validation commands
tool verify --output
tool status --check-all

[Any additional steps needed after main process.]

• Clean up [temporary resources]
• Document [results or decisions]
• Notify [stakeholders or systems]
• Update [tracking or monitoring systems]

Optional: Remove this step if not applicable.

[Explanation of why this is important and how to apply it.]

Example:

**REMOVE THIS SECTION** when creating your actual skill. This guidance is only for template users. 1. **Concise and Actionable**: Every sentence should provide value. Remove fluff.

1. Imperative Form: Write as commands ("Do this", "Check that") not descriptions.

2. Progressive Disclosure:

   • Frontmatter metadata: ~50-100 tokens (always in context)
   • SKILL.md body: 2,000-5,000 tokens (loaded when skill triggered)
   • Supporting resources: Variable (loaded on-demand)

3. Concrete Examples: One good example > 10 paragraphs of explanation.

4. Appropriate Specificity:

   • High freedom: Provide principles, options, and trade-offs
   • Medium freedom: Show preferred patterns with acceptable alternatives
   • Low freedom: Give exact procedures with safety checks

5. Test with Real Tasks: Validate effectiveness with actual agent workflows.
