What it does

Drafts a skill name from your prompt's first line, in the lowercase-and-hyphens form agents require.
Writes a starting description with a "Use when" sentence, so agents know when to load the skill. Sharpen it in your own words.
Turns each blank into a plain instruction: blanks with a default get "If it isn't given, use...", blanks without one get "Ask for it."
Checks the rules from the Agent Skills standard: a valid name up to 64 characters, and a description up to 1,024 characters.
Uploading to the Claude app instead of Claude Code or Codex? Anthropic's help center lists a 200-character limit for descriptions there, so keep it short.

Everything runs in your browser. Your prompt is never sent anywhere.

Install the skill

Make a folder with the skill's name and put the file inside, for example ~/.claude/skills/code-review/SKILL.md for Claude Code. Read how Claude Code skills work, or how to write a SKILL.md by hand.

Keep your prompts and skills in one place, in your own GitHub. Install every skill with one command.
