Unclear What the "Live room" feature is and how a session gets access to it is not established by the evidence.

What

  • A new helper builds extra markdown sections appended to the Artifact/skill system prompt: a "Live files — this session" block, and, when room mode is on and the capability roster includes "room", a "Live room — this session" block.
  • These sections are now appended both to the skill-authoring prompt and to the top-level artifact prompt builder.
  • The function that renders a skill's capability roster now always appends these Live files/Live room sections, including on error or empty-roster paths.

Why This gives the model explicit, up-to-date context about files and rooms that are live/shared during the session, wherever an artifact or skill prompt is built.
