What /onboard does
/onboard is the setup flow. It runs once after install and asks about your business: who you are, what you build, your brand voice, your stack, your goals, and how you plan to use the pack. It writes all of that to a single profile.md file at your pack root.
Every other skill reads that profile on demand, only when it needs context, never at the start of a session. So instead of re-explaining your stack on every task, you tell the pack once and it remembers.
Running it
/onboard in a fresh session. It is a guided, 10 to 20 minute Q&A.onboard adapter, then save the result as profile.md (or paste the relevant parts when a skill needs them).What it captures
Some of these change the actual behavior of skills. For example, your team size shifts the threshold at which a code review convenes a panel, and your budget tier changes the numbers a pricing skill recommends.
Good to know
/onboard writes the profile. Other skills read it; they never overwrite it. Update it by running /onboard again (or a single stage of it).
