Hooks
What cprof 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 dcotelo/cprof > /plugin install cprof@dcotelo
Ships with cprof. 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.

Read the script before you install anything that runs on your machine. This is the one part of a plugin that acts without being asked.
