Agent skills · SKILL.md

One skill format, every agent you already use

SKILL.md started in Claude Code and spread. Cursor, GitHub Copilot, Codex CLI and 20+ other agents now read the same folders, so a skill you install once works wherever you work.

What is inside a SKILL.md file

Two parts. Frontmatter with a name and a description, which tells the agent when the skill applies. Then a body of instructions, which tells it how to do the job. Good skills add a references/ folder for the parts you should customise.

Where the folder goes

Only the install directory differs between agents. In Claude Code it is ~/.claude/skills/ for personal skills, or .claude/skills/ inside a repository for a team. The CreAI pack ships an install guide for every platform.

What makes an agent skill good

  • A trigger-rich description, so the agent knows when the skill applies.
  • One job, done properly.
  • Editable reference files for everything opinionated: rubric, tone, delegation list.
  • Hard safety rules: it drafts, and never sends, posts or spends on its own.
  • Honest failure modes: [FILL IN] placeholders instead of invented facts.

Five ready-made agent skills

The Agent Skills Pack ($29) follows every rule above, with a structural test suite and an install guide for each platform.

  • Lead qualification: Scores and ranks inbound leads against a rubric you edit in plain English, with a written reason for every score.
  • Inbox triage: Labels every email act-now, respond-today, delegate or archive, and drafts a reply for the ones that need one.
  • Content repurposing: Turns one post or transcript into channel-ready drafts in your voice.
  • Meeting actions: Turns a meeting transcript into decisions, owned action items with deadlines, and a drafted follow-up email.
  • Weekly review: Writes an honest weekly review from what actually happened.

FAQ

Which agents support SKILL.md skills?
The CreAI skills are built for Claude Code, Cursor, GitHub Copilot, Codex CLI and 20+ other agents that read SKILL.md. The folder is the same everywhere; only where you put it changes.
Do I need to code to use agent skills?
No. Installing a skill is copying a folder, and customising one is editing a plain-English reference file.
Do skills cost extra to run?
No. A skill is instructions, not a service. It runs inside the agent subscription or API usage you already have.
Can a skill send emails or post for me?
A skill can only do what your agent can do. Every skill CreAI ships drafts for your review and never sends, posts or spends on its own.
