Hooks
What swarm runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
Install
> /plugin marketplace add DheerG/swarms > /plugin install swarm@swarms
Ships with swarm. Installing the plugin gets these hooks.
What fires, and when
SessionStart
Fires once when a session begins, and again after a context compaction. It is where a plugin sets up its environment, or restores state the compaction dropped.
