What problem does it solve? When working across many sessions, it becomes hard to recall what happened recently—what was decided, which tasks moved, and what artifacts were saved. This Skill produces a read-only digest that summarizes activity over a chosen time period so you can quickly reorient without digging through raw records. ## Core Features & Use Cases - Period-based overview: Summarizes activities, decisions, and materials from a specified window (default: last 7 days, auto-shortened to 3 days when volume is high). - Domain grouping: Organizes results by domain: tags so related work is presented together, with uncategorized items listed separately. - Decision classification: Separates settled decisions from ongoing discussion points ([議論中]) and flags superseded decisions so outdated choices are not shown as current. - Use Case: After returning from a week away, ask "今週のまとめ" to get a domain-by-domain digest of completed and in-progress activities, decisions made, and saved materials. ## Quick Start Ask the AI to show a digest of what happened over the past week, such as "最近何やったっけ" or "先週から何が決まった?".
