DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Away Summary [In Development]

What

Automatically generates a brief task summary when the user steps away (window blur detected), so they can quickly re-orient when returning.

Status

Feature-flagged via tengu_sedge_lantern (defaults to false)

Details
  • Triggered by terminal focus/blur events tracked via the presence system
  • Generates summaries under 40 words in 1-2 plain sentences, naming the task and next action
  • Summary is added as a system message of subtype away_summary
  • Uses cached parameters to avoid expensive re-computation
  • Cannot use tools (text-only generation)
Evidence

Away summary generation (search for "The user stepped away and is coming back")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
