## What it does

The skill reads `log.md` and `hot.md` in your Obsidian vault, picks pages created or updated in the chosen period, and writes a structured markdown digest. You get headline insights, tables of new and updated pages, tag frequencies, cross-category links and a short re-read list.

The period comes from your phrasing: "daily", "weekly", "monthly", an ISO date or a number of days. With no argument it takes the last 7 days. If fewer than 5 pages were active, it stops and offers a wider window — a sign worth checking whether the wiki is actually growing.

It needs your vault path. Config resolution follows the protocol in `llm-wiki/SKILL.md`: inline `@name` override, then a walk up the CWD for `.env`, then global config. Without `OBSIDIAN_VAULT_PATH` it asks you to set it up. It also reads `_meta/taxonomy.md` to flag tags that are not in the taxonomy yet.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-digest -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/wiki-digest/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/wiki-digest/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-digest -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/wiki-digest/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-digest -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/wiki-digest/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Ar9av/obsidian-wiki wiki-digest
```

2. **Manually: put the files in place**
- File: `.github/skills/wiki-digest/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-digest -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Ar9av/obsidian-wiki --path .skills/wiki-digest
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/wiki-digest/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill wiki-digest -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Ar9av/obsidian-wiki/tree/HEAD/.skills/wiki-digest/SKILL.md

## When to use it
- produce a weekly digest of fresh notes
- spot the themes that kept coming up this month
- flag new tags missing from the taxonomy
- pick older pages worth re-reading
- count drafts and unpromoted notes in `_raw/`

## Example prompts
- make a weekly digest of my wiki
- show what changed in the last 14 days
- build a monthly digest and flag new tags

# 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`)

For each remaining page, read its frontmatter:
- `created` — when the page was first written
- `updated` — when it was last modified

Classify:
- **New pages**: `created` is within the period
- **Updated pages**: `updated` is within the period but `created` is before it
- **Unchanged**: neither date falls in the period → skip

If fewer than 5 pages were active, note it and offer to widen: *"Only 3 pages were active in the last 7 days — want a monthly digest instead?"* Stop here unless the user says to continue.

For each active page, collect: `title`, `category`, `tags`, `summary` (frontmatter field), `lifecycle`, any `^[ambiguous]` or `^[inferred]` markers in the body.

## Step 2: Identify Themes

From all active pages' tags, tally theme frequency:

```
For each tag across new + updated pages:
  count how many active pages carry it
