Create Skill

The skill

Shows you how to write a short, clean skill.

Only when you ask.

Fewer bugs

Your skills stay short and quick to load. Fewer broken skills.

↻ Runs by itselfevery time a skill file changes

How the habit works.
You don't have to.

Three questionsWhen does it start? How does it check its work? What does it remember?

01

It starts by itself

a SKILL.md changes. Runs in GitHub Actions or Claude Code routine.

  • ↻ a SKILL.md changes
  • push touching **/SKILL.md

02

It checks its work

under 200 lines, valid. If a check fails, it tells you.

  • ✓SKILL.md is under 200 lines
  • ✓the YAML frontmatter has name and description
  • ✓every file linked from SKILL.md exists under references/, scripts/ or assets/

03

It remembers

skill size log. The next run reads it first: skills checked before and their line counts.

loops/skill-size-loop/runs.md

One run, step by step.
Then it stops.

Stop ruleStops after ten SKILL.md files per run.

  1. 01

    Find changed skills

    Collect every SKILL.md touched by the push.

  2. 02

    Count lines

    Each SKILL.md must stay under 200 lines.

  3. 03

    Check frontmatter

    The YAML block needs both name and description.

  4. 04

    Check resources

    Links must point to files that exist in references/, scripts/ or assets/.

  5. 05

    Suggest splits

    For files over the limit, propose which sections move into references/.

  6. 06

    Log results

    Line counts and open issues go into the run log.

What it may do.
Nothing more.

Safe by defaultIt writes only in its own folder and asks you before anything goes out.

Is it for you?
Use it when it fits.

Quick checkRead both lists. If the left one sounds like you, the Create Skill skill helps.

Use it when

  • ✓ You write a new agent skill
  • ✓ A SKILL.md has grown too long
  • ✓ You split a skill into references

Skip it when

  • – You only use skills
  • – You need a full test harness

Questions

Create Skill skill, answered.

Why 200 lines?

The skill treats it as the limit for the SKILL.md body. Longer detail belongs in references/ files that load only when needed.

Does it test skills with models?

No. The skill advises testing with every model you use, which stays a manual step.

How do I install the Create Skill skill?

Copy the prompt at the top into your agent. It installs the skill from siviter-xyz/dot-agent and sets up the habit. Or run npx skills add siviter-xyz/dot-agent --skill create-skill.

Is the Create Skill skill free?

Yes. It is published under MIT. Habit is free too.
