What autoharness runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
Claude Code
> /plugin marketplace add tigerless-labs/autoharness> /plugin install autoharness@autoharness
Cursor
Cursor also runs Claude Code hooks from .claude/settings.json, so copy these hooks there to use them in Cursor.
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.
