## Description

Produce a day/week/month knowledge digest summarizing what was learned, updated, and connected in the wiki. Use for readable recent-learning summaries; wiki-status reports source and ingestion state instead.

# 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

**Writing profile:** Before drafting or rewriting natural-language Markdown, read and apply the `Writing Profile Resolution` section in `llm-wiki/SKILL.md`. Framework schema, provenance, safety, and operation-specific requirements take precedence.
`WRITING.md` preferences apply only to newly drafted or rewritten natural-language Markdown; preserve source content and structured records.

1. **Resolve config**, follow the Config Resolution Protocol in `llm-wiki/SKILL.md` (inline `@name` override → walk up CWD for `.env` → global 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.

## Step 1: Collect Pages Active in the Period

Glob all `.md` files under `$OBSIDIAN_VAULT_PATH`. Skip special/system files:
- `index.md`, `log.md`, `hot.md`, `AGENTS.md`, `_insights.md`
- Anything under `_meta/`, `_archives/`, `_raw/`
- Journal digest pages themselves (`journal/digest-*.md`)
