Hooks
What agents-observe runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
> /plugin marketplace add simple10/agents-observe > /plugin install agents-observe@agents-observe
Ships with agents-observe. Installing the plugin gets these hooks.
What fires, and when
Setup
bash ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/hook.sh
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.
node ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/observe_cli.mjs hook-autostart
SessionEnd
bash ${CLAUDE_PLUGIN_ROOT}/hooks/scripts/hook.sh
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.
