New features

  • Agent can read images. The agent’s Read tool now accepts image files (PNG, JPEG, and friends) and ingests them natively, so you can point it at a screenshot or figure on disk instead of pasting it into chat. See Steering the agent.
  • System prompt in the session transcript. The session viewer’s System card now shows the full system prompt the agent ran with, so you can see exactly what context — including your rules — was in play. See Observability.

​
Updates

  • Rules are inlined in the system prompt. Your writing rules are now baked into the agent’s system prompt under “Rules to obey” instead of being appended to each user turn. The agent has the full rule list on every request, and the rules show up in the transcript. See Steering the agent.
  • Agents reply, they don’t start threads. The agent can only reply on comment threads you’ve opened, not start new ones on its own. Use comments to drive a back-and-forth instead of getting unsolicited threads. See Comments.

Bug fixes

  • Creating a new file no longer carries over state from the previously active tab. New files now open empty as expected.
