Edit .env in your workspace. Add or change KEY=value; remove a line to restore its runtime default. Quote values containing spaces. Keep credentials in Keychain or a secret manager. Credential values are hidden here.
Most changes apply on the next poll or dispatch. Run sq stop, then sq start after changing loop intervals or exported process settings. If a process environment value takes precedence, update or unset that exported variable too. Existing terminal sessions may need reopening. Review agent model and permission changes before saving.
