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.

Names in this entry

flagtengu_sedge_lantern
/recap and the Session recap settings entry now work for everyone without an experiment flag.
envCLAUDE_CODE_ENABLE_AWAY_SUMMARY
Override session recap availability. Set to 0 to force recaps off regardless of the /config toggle. Set to 1 to force recaps on when awaySummaryEnabled is false. Takes precedence over the setting and /config toggle
slash/config
Open the Settings interface to adjust theme, model, output style, and other preferences. Pass one or more key=value pairs to set a setting directly without opening the interface, for example /config thinking=false, /config theme=dark, or /config model=sonnet. The key=value form also works in non-interactive mode (-p) and from the Claude mobile app via Remote Control. The key=value form can't turn on a setting that needs your confirmation in the panel, such as autoContinueAtUsageLimit, though it can turn one off. Run /config --help to list the keys it accepts. Alias: /settings
settingawaySummaryEnabled
Turn off the session recap shown when you come back to the terminal
slash/recap
Generate a one-line summary of the current session on demand. See Session recap for the automatic recap that appears after you've been away

Anthropic's note

Upstream's own release notes for v2.1.105 name something this entry names, so the two are probably about the same change. Probably: the pairing is made on a shared name rather than on the words around it.

Improved /config labels and descriptions for clarity

Is this right?

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.
