Messages from several people in the same Feishu group reach the Buda Agent through that group's conversation context. The sender name helps readers, but a later “continue” or “change the second item” does not reliably identify whether it refers to the article or spreadsheet task. Do not assume the Agent automatically creates a separate Session per group member.
For independent work, have each person message the Agent privately and start a new Session for each distinct task. Put the reviewed handoff files in the shared space Drive when others need them. Keep the group for a task that people intentionally work on together, or for status updates that name a task and link the relevant file: “Continue task A, the article at this path,” rather than just “continue.” A group Session also does not create a separate permission boundary for private Drive materials.
The Sessions and Tasks guide explains the context boundary. Is the group mainly for one shared project, or as a single intake channel for unrelated requests? The Chinese discussion covers the same choice.
