Wiki Digest — Knowledge Newsletter Generator

You are generating a human-readable digest of recent wiki activity: what was learned, what was updated, what themes are emerging, and what's worth reviewing. This skill summarizes knowledge, not sources — think of it as a weekly review session, not an ingestion status report.

Before You Start

1. Resolve config — follow the Config Resolution Protocol in llm-wiki/SKILL.md (walk up CWD for .env → ~/.obsidian-wiki/config → prompt setup). This gives OBSIDIAN_VAULT_PATH and OBSIDIAN_LINK_FORMAT.
2. Parse the period from the user's request:
   • "daily" / "today" / "yesterday" → last 24 hours
   • "weekly" / "this week" / no argument (default) → last 7 days
   • "monthly" / "this month" → last 30 days
   • ISO date like "since 2026-05-01" → pages updated since that date
   • Explicit number like "last 14 days" → that many days
3. Read $OBSIDIAN_VAULT_PATH/log.md — last 200 lines — for entries within the period (timestamps are ISO-8601 prefixed lines).
4. Read $OBSIDIAN_VAULT_PATH/hot.md for current session context.
5. If $OBSIDIAN_VAULT_PATH/_insights.md exists, read its Anchor Pages table — you'll use it later to identify which new pages became hubs.
