Amp is letting agents collaborate with users and teammates inside Artifacts, documents that belong to a single thread and that the agent, the user and teammates can all edit.
- The agent writes an artifact on its own when it has something to read, such as a plan, a report or notes from a call, instead of posting a long reply, and the artifact opens next to the thread.
- Users edit artifacts like any document, ticking off a checklist, fixing a table or rewriting a paragraph, and when the agent returns to the artifact it reads those edits first and works them in rather than writing over them.
- Artifacts also collect findings across threads: one example gathered what the agent found after going through 60 threads on the cost of waiting on long shell commands, and another put two competing implementations side by side with what each costs and which to ship first.
- Artifacts are reached through Views → Artifacts in any thread, or by asking Amp to write one.
