Skill Authoring Coach

Use this skill to help users design, review, genericise, and package reusable Agent Skills.

Purpose

A good skill is not a long prompt dump. It is a focused, reusable capability with:

• A clear trigger description.
• Practical step-by-step instructions.
• Guardrails and edge cases.
• Optional references, assets, or scripts.
• A compact structure that an agent can load when needed.

Skill vs reference vs template

Use these distinctions:

• Skill - Teaches the agent how to perform a repeatable task or workflow.
• Reference - Supplies detailed information the skill may need, such as policies, rubrics, examples, taxonomies, or checklists.
• Template - Supplies a reusable output shape or file structure.
• Script - Performs deterministic work that should not rely on prose instructions alone.

If the user tries to put everything into SKILL.md, recommend moving detailed lookup material into references/ and static output structures into assets/.

Recommended skill shape

<skill-folder>/
├── SKILL.md
├── references/      optional
├── assets/          optional
└── scripts/         optional

The SKILL.md should contain:

1. Frontmatter with name and description.
2. A short explanation of when to use the skill.
3. Inputs to look for.
4. Workflow steps.
5. Output formats.
6. Guardrails and quality checks.

Workflow

1. Identify the workflow the user wants to package.
2. Decide whether it should be a skill, reference, template, script, or combination.
3. Write or improve the skill trigger description.
4. Keep instructions concise and operational.
5. Move long examples and detailed reference material out of SKILL.md where appropriate.
6. Check for sensitive, organisation-specific, or non-reusable content.
7. Produce a candidate folder structure and files.

Review rubric

Score candidate skills from 0 to 5 on:

1. Trigger clarity - Will the agent know when to use it?
2. Task focus - Is it one coherent capability?
3. Instruction quality - Are the steps clear and repeatable?
4. Portability - Can others use it without private assumptions?
5. Safety and evidence discipline - Does it avoid invented claims, secret leakage, or risky actions?
6. Packaging quality - Are references, assets, and scripts separated cleanly?

## References

This skill includes supporting reference material. Read the relevant reference file when the task needs additional structure, rubric detail, examples, or checklist support.

- `references/skill-design-checklist.md` - use this when additional structure, examples, or checks are useful for the task.

## Quality checklist

Before responding, check:

- The proposed skill has a clear reusable job.
- The trigger description is precise.
- Organisation-specific material is removed or parameterised.
- Long reference content is not overloaded into the main skill file.
- The result is practical for a maker to copy into a skills repository.
