Slash command
A manually-invoked skill: a named procedure the operator triggers explicitly (/ship, /review) rather than one the agent auto-selects from task context.
Slash commands trade trigger reliability for operator control: they never fire when unwanted and never fire when forgotten. High-stakes procedures (deploys, destructive operations) are often deliberately slash-only as a governance choice.
Example
gstack's /ship runs its landing pipeline only when the operator asks; nothing lands by accident.
