Hooks
What orchestrator runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
> /plugin marketplace add Rylaa/fable5-opus5-orchestrator > /plugin install orchestrator@fable-orchestrator
Ships with orchestrator. 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.
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/inject_instructions.py"
UserPromptSubmit
Fires before Claude sees each prompt you send. A plugin can use it to inject context, so the same instruction reaches the model every turn instead of only at session start.
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/remind_chair.py"

Run Claude Fable 5 all day — without watching the usage meter. Fable 5 is the best chair a Claude Code session can have, and the most expensive seat in the house. Let it type every token itself and the session ends rate-limited, waiting out the reset window.
