Preview, save, and ask your agent to edit files

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.

Try it · Open brief.md and select 分屏 on a wide screen; locate 对话全屏 and 文件全屏.

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.

Try it · Select 源码, change 17:00 to 18:00, and observe that Save becomes available.

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.

Try it · Select 保存文件, wait for 已保存, then return to 预览 and check 18:00.

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.

Try it · Save and stop manual editing; reference brief.md and request a checklist while preserving the reception hours.

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.

Try it · Review the proposed paragraph-to-checklist diff, verify the hours are unchanged, and select Approve.

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.

Try it · Reopen brief.md after the illustrated DeepAgents success; contrast it with CLI output under generated/runtime.

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.

Try it · Make a small manual edit and request an Agent revision in the teaching file, then inspect the original.
