Hooks
What trigger-tree runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
$ npx -y skills add Hedde/trigger_tree --agent claude-codeShips with trigger-tree. 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.
- Runs fi.
UserPromptSubmit
Fires before Claude sees each prompt you send. A plugin can use it to inject context, so the same instruction reaches the model every turn instead of only at session start.
- Runs fi.
PostToolUse
- Runs fi.
Stop
- Runs fi.
