Artifacts are session outputs that are better reviewed outside the chat transcript. Agents create artifacts for rich walkthroughs, diagrams, dashboards, reports, structured exports, screenshots, PDFs, and other files.

​
View artifacts

Open a session and select Artifacts in the sidebar. Tembo groups artifacts into sections for sources, files, plans, and generated outputs. HTML artifacts open in a preview with actions to copy a link, download the file, or open the artifact full screen. Files and plans open in a preview dialog on desktop and a bottom sheet on mobile.

​
When agents create artifacts

Agents create artifacts when a self-contained output is easier to scan, share, or revisit than a long chat response. Good examples include:
  • PR walkthroughs
  • Bug explainers
  • Architecture maps
  • Security findings
  • License audits
  • Incident timelines
  • Cloud cost maps
  • UX variations
  • Release checklists
  • Rollout plans
Artifacts stay attached to the session and use the same organization and session access controls as the rest of the work.
