What problem does it solve? Starting a personal knowledge vault from zero means weeks of empty notes before the system becomes useful. This Skill bootstraps the vault on Day 1 by reconstructing 1–6 months of work history from email, calendar, drive, and chat sources, so the second brain starts with an already-living knowledge base. ## Core Features & Use Cases - Stakeholder Mapping: Scans calendar events and email threads to identify top recurring contacts, then creates validated person notes with frontmatter and monthly aggregated timelines. - Project & Decision Detection: Detects candidate projects from recurring topics and historical decisions from keywords like "approved" or "we've decided", creating notes only after user validation. - Backfill Report: Generates a meta report documenting the window, sources, stats, and caveats so future sessions weight backfilled notes appropriately. - Use Case: On your first day with the system, ask to backfill the last 3 months; the Skill proposes a shortlist of ~15 stakeholders and 4 projects, you validate each phase, and it creates 30–60 high-quality notes marked as backfilled. ## Quick Start Ask the assistant to kickstart the vault by backfilling the last 3 months from calendar and email in strategic mode.
