A tool is an action Arro takes in one of your connected apps: post a Slack message, create a Trello card, or search your Notion workspace. It works in the app itself rather than by driving your mouse and keyboard. Tools come from installed, enabled Plugins with the required app connected in your current workspace. Saved authorization alone does not make tools available. Manage each action’s permission in the plugin’s connection settings.

Plugin tools

Plugin tools are the ones you can see and control. Each connected service publishes its own set, such as Notion Search and Create page, or Slack Read channel and Post message. On a connection’s manage page, tools are split into Read-only and Write/delete groups, and each tool can be set to Always allow, Needs approval, or Blocked. A blocked tool is never used. Defaults, group dropdowns, and how the agent applies your settings are covered under per-tool permissions.

Continue an interrupted task

Arro carries recorded plugin results into continued tasks. If an action was approved but its final result could not be recorded, Arro treats its outcome as unknown and checks what happened before retrying. Approval alone does not confirm that an email was sent or another action completed.
