Everything Silicon Workers touches is local and documented, so uninstalling is a few lines of config and one folder. Nothing was ever uploaded, so there's nothing to delete anywhere else.
Open ~/.claude/settings.json and delete the entries in the hooks section that reference butler-hook.sh — or simply restore the backup that was created when you connected:
~/.claude/settings.json.backup-butler
Your own pre-existing hooks are untouched either way (connecting only ever appended).
~/.codex/config.toml, set notify back to your original command — or restore config.toml.backup-butler.~/.butler/hooks/codex-notify-forward if it exists.~/.butler/ — it holds the hook scripts, the event log (events.jsonl), and task state (tasks.json). That's every byte the app ever wrote.~/.butler/, so no running session tries to write to a missing script.Changed your mind? Download it again — reconnecting is idempotent and restores nothing you deleted.
