Hooks
What opik runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
Install
$ npx -y skills add comet-ml/opik-claude-code-plugin --agent claude-codeShips with opik. Installing the plugin gets these hooks.
What fires, and when
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.
