focus-mode

"Leave me alone for <N> hours." Three steps: block calendar, set IM DND, optionally post to team.

Verbs (the installed lark-* skills): calendar +create (--summary/--start/--end/--description — note: CLI has NO free-busy-status or visibility flag), im +messages-send (--chat-id/--text). Atomic shapes + token flags: connectors/LARK-RECIPES.md.

Limitation — DND not settable via CLI

im has no +set-status/+set-dnd verb. DND must be set manually in Lark IM UI (Settings → Notifications → Do Not Disturb). This skill: creates the calendar block, optionally posts to team, and suggests the user set DND manually.

Workflow

1. Parse duration + start from message: "block 2 tiếng chiều nay"

→ start now+30min, 2h; "DND tới 17h" → start now, end 17:00; explicit window → use as-is. Ambiguous → ask.

1. Parse topic (optional) → event title "Focus — <topic>", else

"Focus block".

1. Echo confirm: calendar block window + title, optional team

post, DND reminder. Wait y/n.

1. Execute (after confirm):

`` calendar +create --summary "Focus — <topic>" --start "<t>" --end "<t>" # optional: im +messages-send --chat-id <team-group> --text "🎧 Focus mode tới <end>. Urgent thì DM." ``

1. Output: block created until <end> + calendar URL + team

notified/skipped + reminder to set DND in Lark UI.

Hard rules

1. Confirmation gate — echo intent + wait y/n, especially the team post.
2. Don't auto-decline existing meetings in the focus window — surface

conflict, let user pick decline/skip/re-block.

1. DND isn't silent — IM still receives, just no notify; user should re-check.
2. Don't extend silently — window ends, focus ends. Re-invoke to extend.
3. Don't notify group if user is solo — check memory/team-roster.md.

Edge cases

• Mid-meeting trigger → start = meeting end + 5min, not now.
• Across midnight → split into 2 events or multi-day.
• Weekend/off-hours (working-hours.md) → warn "ngoài giờ làm, vẫn block?".

Memory

Optional: working-hours.md (off-hours warning), team-roster.md (which group to notify). Missing → skip optional steps.
