Multi-Client AI Skill Builder
Turn a repeatable AI workflow into a reusable skill file for Codex, Claude, Cursor, or a generic AI agent. The generator is local, copy-only, and does not call an AI model.

What this builder is for
AI skills are reusable instructions for repeated work. Instead of pasting the same long prompt every time, you can define when the workflow should trigger, what steps the assistant should follow, what output you expect, and what risks it must avoid.
This page focuses on portable skill writing. It does not install anything, execute scripts, or connect to an AI account. That keeps the first version fast, private, and useful across several clients.
Success sign: after copying the generated file, another person should understand when to use the skill, what it does, and what it must not do.
Client format guide
Codex AGENTS.md
Best for project-level coding guidance. Put stable repo rules, workflow preferences, and verification expectations in the generated section.
Claude SKILL.md
Best for reusable skills with a clear name, description, trigger, steps, and optional examples.
Cursor rules
Best for editor-level project rules. Keep the scope narrow so the rule helps without overriding every request.
Generic agent skill
Best when you want a portable Markdown prompt for ChatGPT, custom agents, or another tool.
Limitations
The builder cannot prove a skill is safe, complete, or supported by a specific client version. It also cannot inspect scripts, dependencies, or external repositories. Treat the output as a strong draft, then review it before use.

Frequently asked questions
Does this call an AI model?
No. The builder runs in your browser and formats the fields you provide into client-specific Markdown. Nothing is uploaded.
Which AI clients does it support?
The first version supports Codex AGENTS.md style instructions, Claude SKILL.md files, Cursor project rules, and a generic agent skill prompt.
Can I install a generated skill automatically?
No. The output is copy-ready text only. Automatic install is intentionally out of scope because skills can contain risky instructions or scripts.
What makes a good AI skill?
A good skill has a clear trigger, narrow scope, concrete steps, output expectations, safety limits, and a success check.
