Slice a whole capability into ordered releasable increments (increment backlog in increments/<stem>.md). Delegate each slice to skills/new-increment — do not implement slices yourself. Default step mode stops after each increment for feedback; automatic mode (explicit opt-in) continues until the backlog is done. Use for an entire feature or epic (e.g. full FizzBuzz), not for implementing one increment.
$npx -y skills add dan-the-dev/xp-developer-skills --skill new-featureInstalls into the current project.
Run `npx skills use "https://github.com/dan-the-dev/xp-developer-skills" --skill "dan-the-dev/xp-developer-skills/new-feature"` and follow the generated skill instructions now. Read its complete output, redirecting it to a temporary file first if necessary. Resolve relative paths from the supporting-files directory it provides.
Use the skills in "https://github.com/dan-the-dev/xp-developer-skills" that are relevant to the current task. Run `npx skills add "https://github.com/dan-the-dev/xp-developer-skills"` and select the relevant skills, then follow their instructions.
