## What it does

The skill performs a structural health check on an Obsidian vault in a report-only format. It detects pages with zero incoming wikilinks, flags broken targets while accounting for section anchors and aliases, and inspects frontmatter fields like `title`, `tags`, `sources`, and `updated`. Folders such as `_archives/`, `_raw/`, `_readouts/`, and `.obsidian/` are skipped automatically.

The process avoids bulk file reads by relying on frontmatter-scoped greps and targeted section lookups. When the `obsidian-wiki` executable is present on PATH, it runs `obsidian-wiki lint "$OBSIDIAN_VAULT_PATH" --json` with schema rules defined in `$OBSIDIAN_VAULT_PATH/AGENTS.md`. If the CLI is absent, it executes deterministic grep routines instead.

It requires the `OBSIDIAN_VAULT_PATH` environment variable or a local `.env` file to locate the vault. Any empty or whitespace-only configuration values cause the run to fail closed immediately rather than falling back to defaults.

## Requirements
- Works with: Obsidian

## Install

### Claude Code (native platform)

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/Ar9av/obsidian-wiki --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 Ar9av/obsidian-wiki --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/Ar9av/obsidian-wiki/tree/HEAD/.skills/wiki-lint/SKILL.md

## When to use it
- identify orphan pages lacking incoming wikilinks
- detect broken wikilinks to missing markdown files
- flag notes missing required frontmatter attributes
- spot stale content by checking source modification timestamps

## Example prompts
- Run a wiki health check using wiki-lint
- Scan the Obsidian vault for broken wikilinks and orphan notes

# Wiki Lint — Health Audit

You are performing a health check on an Obsidian wiki. Your goal is to find and fix structural issues that degrade the wiki's value over time.

**Before scanning anything:** follow the Retrieval Primitives table in `llm-wiki/SKILL.md`. Prefer frontmatter-scoped greps and section-anchored reads over full-page reads. On a large vault, blindly reading every page to lint it is exactly what this framework is built to avoid.

## 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.
Apply `WRITING.md` preferences only to generated consolidation reports; deterministic findings and fixes keep their existing formats.

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` plus any `OBSIDIAN_ALLOWED_LIFECYCLES`, `OBSIDIAN_ALLOWED_RELATIONSHIP_TYPES`, `OBSIDIAN_REQUIRED_TRUST_FIELDS`, and `OBSIDIAN_SCHEMA_SOURCE` values.
2. **Read owner rules** — if `$OBSIDIAN_VAULT_PATH/AGENTS.md` exists, read it before interpreting any schema. Owner rules override framework defaults.
3. **Form the effective schema** — record the schema source locator plus effective required/optional frontmatter, lifecycle values, relationship types, and provenance markers. Framework values are defaults; preserve owner extensions and relaxed requiredness exactly. Never coerce an owner type to a framework type.
4. Read `index.md` for the full page inventory
5. Read `log.md` for recent activity context

Pass the effective schema to deterministic checks explicitly. For example, add each owner extension with `--allow-lifecycle` / `--allow-relationship-type`, replace trust requiredness with repeatable `--required-trust-field`, and identify the authority with `--schema-source "$OBSIDIAN_VAULT_PATH/AGENTS.md"`. The JSON report's `schema` block must match the schema you formed before findings are accepted.

Schema precedence is CLI flags > resolved environment/config values > framework defaults; lifecycle and relationship extensions remain additive. Strip every override before use. An explicitly configured empty or whitespace-only value—and any empty comma-separated list entry—fails closed; never treat it as a valid lifecycle, relationship type, required field, or authority locator. Remove the variable instead when defaults are intended.
```
