## What it does

daily-update runs a maintenance cycle for an Obsidian wiki. It compares source file modification times with `.manifest.json`, classifies sources as fresh, stale, or missing, then calls `obsidian-wiki memory index` and `obsidian-wiki memory hot`. The index is reconciled with pages on disk, while `hot.md` receives refreshed activity and status sections.

The skill writes vault-scoped state, appends a record to `log.md`, and runs `impl-validator` after the cycle. A scheduled `wiki-lint` check can run in `manual`, `daily`, or `weekly` mode. Setup mode configures a 9 AM launch through launchd, systemd, or cron, with an optional terminal reminder.

If the vault is unmigrated, the cycle stops until `obsidian-wiki memory migrate` and then `--apply` are run. Check migration first when preparing a new vault.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

```bash
npx skills add Ar9av/obsidian-wiki --skill daily-update -a claude-code
```

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Ar9av/obsidian-wiki --skill daily-update -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/daily-update/SKILL.md

## When to use it
- check source freshness in `.manifest.json`
- reconcile the page index with the vault contents
- refresh `hot.md` and persist cycle state
- configure a daily launch with launchd, systemd, or cron
- run scheduled `wiki-lint` health checks

## Example prompts
- Run `daily-update` to refresh my Obsidian wiki this morning.
- Set up `daily-update` to run through cron at 9 AM.
- Check the vault, refresh the index and `hot.md`, then report stale sources.

# Daily Update — Wiki Maintenance Cycle

You run a lightweight maintenance pass over the wiki: check source freshness, refresh the index, update hot.md, and write the state file that the terminal notification reads.

## Before You Start

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_WIKI_REPO`.
2. **Derive vault-scoped state dir** — all runtime state is scoped to the resolved vault, not global:
   ```bash
   VAULT_ID=$(echo "$OBSIDIAN_VAULT_PATH" | md5sum 2>/dev/null | cut -c1-8 || md5 -q - <<< "$OBSIDIAN_VAULT_PATH" | cut -c1-8)
   STATE_DIR="$(obsidian_wiki_config_dir)/state/$VAULT_ID"
   mkdir -p "$STATE_DIR"
   ```
3. Read `$OBSIDIAN_VAULT_PATH/.manifest.json`.

## Modes

### Run Mode (default — triggered by cron or `/daily-update`)

Execute the maintenance cycle:

**Step 1: Source freshness check**

Compare each source in `.manifest.json` against its file's modification time. Classify as:
- **Fresh** — `mtime ≤ ingested_at`
- **Stale** — `mtime > ingested_at` (new content exists, not yet ingested)
- **Missing** — source file no longer exists

**Step 2: Index refresh**

```bash
obsidian-wiki memory index --vault "$OBSIDIAN_VAULT_PATH"
```

This reconciles `index.md` against the pages on disk under the memory lock — missing entries added, entries for deleted pages removed, the owner's own sections left untouched. Note `added`/`removed` from the output for the log line in Step 6. Do not enumerate pages with `find` and edit the index by hand.

**Step 3: hot.md update**

```bash
obsidian-wiki memory hot --vault "$OBSIDIAN_VAULT_PATH"
```

Recent Activity, Active Threads, and Flagged Contradictions are regenerated from the log, the todo index, and page frontmatter; `## Key Takeaways` carries across unchanged. If the takeaways are older than ~48h *and* the vault has changed materially since, refresh them: read the 10 most recently updated pages and pass a fresh ~500-word snapshot with `--takeaways -` on stdin. Otherwise leave them — a rebuild without new takeaways is cheap and correct.

If either command reports the vault is **unmigrated**, stop and tell the user to run `obsidian-wiki memory migrate` (preview) then `--apply`; do not fall back to hand-editing.

**Step 4: Write state**

Write to the vault-scoped `$STATE_DIR` derived in "Before You Start":

```bash
date +%s > "$STATE_DIR/.last_update"
echo "<stale_count>" > "$STATE_DIR/.pending_delta"
echo "$OBSIDIAN_VAULT_PATH" > "$STATE_DIR/.vault_path"
```

**Step 4a: Scheduled health check (wiki-lint)**
