# wiki-lint

Runs a deterministic read-only check on an Obsidian vault: dead links, orphan pages, frontmatter gaps. It reports, it does not repair.

## What it does

The skill drives a portable lint engine that ships with the installed product. It reads vault state and returns findings: dead or ambiguous links, orphan pages, missing required frontmatter (including `title`), empty sections, stale index entries, and source/claim ledger contract violations. It does not do semantic or prose-level contradiction analysis, so do not claim that it did.

The parser handles Obsidian wikilinks and embeds, Markdown links, aliases, heading and block fragments, escaped aliases, and code fences. Dot-prefixed directories are skipped, mirroring Obsidian's own indexer. Link resolution honors `.gitignore` files inside the vault without spawning `git`: when a link is ambiguous between a page and a gitignored file such as a build artifact, the gitignored candidate is dropped. The repeatable `--exclude GLOB` flag scopes a path out of page, link, orphan, frontmatter, empty-section, and stale-index scanning.

You need Python 3 and the path to the installed product: the engine sits at `scripts/claude-obsidian.py` and runs as `python3 "$CORE" lint --vault "$VAULT"`. Add `--strict` only when a nonzero exit for findings helps your automation; the command stays read-only either way. Repair is a separate operation. Re-read each target and record its expected SHA-256, draft only the selected changes, build one repair bundle with a new operation ID, inspect it, then apply after that review. Lint never auto-fixes and never commits Git.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install AgriciDaniel/claude-obsidian wiki-lint
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/AgriciDaniel/claude-obsidian --path skills/wiki-lint
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add AgriciDaniel/claude-obsidian --skill wiki-lint -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/AgriciDaniel/claude-obsidian/tree/HEAD/skills/wiki-lint/SKILL.md

## When to use it
- find dead links across an Obsidian vault
- list orphan pages with no inbound links
- catch missing required frontmatter fields such as `title`
- spot empty sections and stale index entries
- check source and claim ledger contract violations

## Example prompts
- run wiki-lint on my Obsidian vault
- check vault health and show orphans and dead links
- run lint with `--exclude "wiki/scratchpad/*"`

description: "Run a deterministic, read-only health check on an Obsidian wiki.

# Lint the wiki

Use the portable lint engine as the source of truth. Lint observes vault state;
it does not create reports, dashboards, canvases, stubs, or fixes.

Resolve the installed product root from this skill's own location, not from the
vault or current working directory:

```bash
PRODUCT_ROOT=/absolute/path/to/installed/claude-obsidian
CORE="$PRODUCT_ROOT/scripts/claude-obsidian.py"
test -f "$CORE"
```

Every `../wiki/references/` link in this file resolves the same way, relative
to this skill's own directory under `$PRODUCT_ROOT`, never relative to the
selected vault's `wiki/` directory.

## Run

Resolve the user vault, then run one of:

```bash
python3 "$CORE" lint --vault "$VAULT"
python3 "$CORE" lint --vault "$VAULT" --format markdown
python3 "$CORE" lint --vault "$VAULT" --exclude "wiki/scratchpad/*"
```

The repeatable `--exclude GLOB` flag scopes a path (for example a scratchpad
folder) out of page, link-resolution, orphan, frontmatter, empty-section, and
stale-index scanning.

Use `--strict` only when a nonzero exit for findings is useful in automation.
The command remains read-only either way.

The deterministic parser understands Obsidian wikilinks and embeds, Markdown
links, aliases, heading and block fragments, escaped aliases, and code fences.
It skips dot-prefixed directories by default, mirroring Obsidian's own
indexer. Link resolution honors `.gitignore` files inside the vault (no `git`
subprocess): when a link is ambiguous between a page and a gitignored file
such as a build artifact, the gitignored candidate is dropped.
It reports such categories as dead or ambiguous links, orphan pages, required
frontmatter gaps (including `title`), empty sections, stale index entries, and
source/claim ledger contract violations. Report only the
checks and counts present in its output; do not claim that it performed
semantic, stylistic, or prose-level contradiction analysis when it did
not.
