Google Calendar Free Up Time Skill for Codex

Google Calendar Free Up Time

Use this skill when the goal is to create time, not just inspect time.

Relevant Actions

• Use search_events to map the day's current fragmentation and identify movable candidates.
• Use read_event or read_event_all_fields when one candidate meeting needs a closer look before proposing a move.
• Use create_event when the user explicitly wants a temporary hold or focus block once the target slot is grounded.
• Use update_event only after the proposal is clear and set update_scope to this_instance, entire_series, or this_and_following once the correct scope of change is grounded.

Workflow

• Start by identifying the target: today, tomorrow, this afternoon, a specific day, or a broader window. If the user already gave a concrete window or duration, work inside it before asking follow-up questions.
• Optimize for contiguous free blocks, not raw free-minute totals.
• Identify which meetings are likely fixed and which are more movable before proposing changes.
• If the user explicitly wants a temporary hold or focus block rather than a reschedule plan, choose the best qualifying free slot and create the hold once the slot is clear.
• Look for the smallest edit set that creates a meaningful uninterrupted block.
• Prefer solutions that reduce fragmentation across the rest of the day, not just one local gap.
• If no clean block exists, show the best partial win and what tradeoff it requires.

Prioritization Heuristics

• Protect hard anchors such as external meetings, major reviews, commute buffers, or lunch if it is already a stable part of the day.
• Move lower-cost meetings first, such as optional events, transparent holds, lightweight internal syncs, or self-created placeholders.
• Favor one or two coherent shifts over a chain of many tiny moves.
• Prefer creating one useful block over scattering a few small openings.

Output Conventions

• Show the before-and-after effect of the proposal.
• Name the block of time created and the minimum meetings that would need to move.
• When creating a hold, state the exact slot and whether the hold is transparent or busy.
• If suggesting multiple options, keep them short and explain the tradeoff for each.
