# Skill Creator A skill for creating new bb skills and iteratively improving them. At a high level the process looks like this: - Decide what the skill should do and roughly how it should do it - Write a draft of the skill into `~/.bb/skills/<name>/SKILL.md` - Try it on a few realistic prompts by spawning bb threads, with and without the skill - Evaluate the results with the user, both qualitatively and with a few objective checks - Rewrite the skill based on what you learned - Repeat until you are both satisfied - Optionally tune the description so the skill triggers reliably Your job is to figure out where the user is in this process and jump in. Maybe they say "I want a skill for X" — then help narrow the intent, write a draft, pick test prompts, run them, and iterate. Maybe they already have a draft — then go straight to the test/iterate loop. And if they say "I don't need a bunch of evals, just vibe with me," do that instead. Be flexible. ## How skills work in bb - **Location.** A skill is a directory with a `SKILL.md` file. User skills live under `~/.bb/skills/<name>/`. The directory name must exactly match the `name` in the frontmatter. - **Frontmatter.** `SKILL.md` must begin with a plain `---` delimiter on its own line, followed by `name` and `description`, then a closing `---`. `name` must be lowercase letters, numbers, and single hyphens (no double hyphens, no spaces, ≤64 chars). `description` must be non-empty and ≤1024 chars. - **Discovery.** bb loads skill...
