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.

- 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.
