Open the file panel and select the brief. On a wide desktop chat, split view keeps it beside the conversation; narrower layouts may show the file separately.

Markdown opens as a formatted preview. Switch to Source to edit the text. Change the closing time from five to six, leaving the change unsaved for now.

Select Save file or use the save shortcut, then check the saved status. Edits made during saving still need another save. Closing a dirty tab asks for confirmation.

For a larger revision, reference the file in DeepAgents and state what to change and preserve. Check the write region and avoid simultaneous manual edits.

When approval appears, red shows removals and green additions. Check the path and diff before approving or rejecting. A pending proposal is not a completed edit.

Wait for a successful tool result, then open the target file. With CLI, check the archived output path. The agent saying “edited” is not sufficient verification.

Practice one small manual save and one Agent-assisted paragraph revision. For each, verify the saved state and target file so the update has a checkable result.
