Source Intelligence

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.

Claude Code v2.1.105

Session Recap (Away Summary) [Gradual Rollout]

What

When you return to a session after being away for 5+ minutes, Claude generates a brief recap of where things left off.

Status

Feature-flagged behind tengu_sedge_lantern (default: false). Can be force-enabled with CLAUDE_CODE_ENABLE_AWAY_SUMMARY=1.

Details
  • Tracks focus/blur events to detect when the user steps away
  • On return, generates a recap: "under 40 words, 1-2 plain sentences, no markdown. Lead with the overall goal and current task, then the one next action."
  • Toggleable in /config via awaySummaryEnabled setting (when the flag is on)
  • Recap can be cancelled, and shows "No recap available" if generation fails
  • A /recap command is also available to manually trigger a recap
  • SDK event: memory_recall emitted when memories are surfaced

Orphaned Tip: ⚠️ Users who get the flag enabled may see "(disable recaps in /config)" — but the feature doesn't work unless the flag is active.

Evidence

Feature gate (search for "tengu_sedge_lantern") and env override (search for "CLAUDE_CODE_ENABLE_AWAY_SUMMARY")

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