Agent Artifacts are durable outputs that Kiro creates during a chat session. Instead of leaving a document, diagram, or preview buried in the conversation, Kiro presents it as an artifact that you can open again while the session is available.
Artifacts are session outputs, not project files. Creating an artifact does not add it to your repository or commit it to version control. If you need the content in your project, ask Kiro to create or update a project file separately.
Kiro can display these artifact types:
PowerPoint (.pptx) artifacts appear as a text outline. HTML artifacts do not run scripts, so interactions that depend on JavaScript are unavailable. Each artifact has a maximum payload size of 12 MB.
When an agent creates an artifact, a compact preview appears in the chat transcript. Open the preview to inspect the artifact without searching through the conversation.
In Agent Focus Mode, selecting an artifact preview expands the session details panel on that artifact and renders it there. The panel lists every artifact from the session, so you can return to one later, and Open in IDE opens it in the editor.
Kiro stores artifacts per session in its global application storage, outside your project's .kiro directory. They remain associated with the chat session and do not overwrite local Steering, Specs, Hooks, or other project configuration.
Treat artifacts as session outputs rather than a substitute for source control. Save important content to your project or another durable system when it needs to follow your normal review, backup, and versioning process.
