## What it does

The skill targets the local docs clone at `~/.claude-code-docs/`. It first looks for `paths_manifest.json`. No manifest means the plugin was never installed or the docs were never cloned, and the skill prints the install commands.

Freshness comes from two signals: the manifest build time and the last git update of the clone. A manifest older than roughly a day is normally refreshed by the SessionStart hook on your next session. Doing it by hand means running `git fetch origin main` and `git reset --hard origin/main` inside the docs directory. After that the skill reads cache state through `fetch-docs.sh status`, which reports manifest pages, cached pages and pending ones.

URL checking is a separate step, handled by `validate-paths.sh`. There is a fast pass with `--quick` and a full scan that runs 1-2 minutes. The script pulls addresses straight from the manifest and summarizes reachable, broken and timed-out entries. If broken URLs survive a `git pull`, the upstream page probably moved, and the repo issues page is the place to report it. For counts, `jq` against the manifest gives the total and a per-category breakdown.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add costiash/claude-code-docs --skill claude-docs-validate -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add costiash/claude-code-docs --skill claude-docs-validate -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add costiash/claude-code-docs --skill claude-docs-validate -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install costiash/claude-code-docs claude-docs-validate
```

2. **Manually: put the files in place**
- File: `.github/skills/claude-docs-validate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add costiash/claude-code-docs --skill claude-docs-validate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/costiash/claude-code-docs --path plugin/skills/claude-docs-validate
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add costiash/claude-code-docs --skill claude-docs-validate -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/costiash/claude-code-docs/tree/HEAD/plugin/skills/claude-docs-validate/SKILL.md

## When to use it
- tell whether the local Claude docs clone has gone stale
- spot broken or unreachable URLs in the docs manifest
- see how many pages are cached and how many are pending
- refresh the docs clone by hand when the hook did not run
- count documentation pages by category

## Example prompts
- Check whether my local Claude docs are current
- Validate the documentation and find broken links
- Show me the doc statistics by category

  Check the health and freshness of locally-stored Claude documentation.
  Use this skill when the user asks about documentation health, broken links,
  stale docs, freshness checks, or wants to validate that their local install
  is up-to-date and all URLs are reachable. Triggers on: "are my docs current",
  "check doc health", "validate documentation", "broken links", "stale docs".

# Claude Documentation Validation Skill

Check whether the local documentation clone at `~/.claude-code-docs/` is healthy and up-to-date.

## When to Use This Skill

Activate when the user asks about:
- Documentation freshness or staleness
- Broken links or unreachable docs
- Health checks on their local install
- Whether docs need updating

## Validation Workflow

### Step 1: Check if the metadata is installed

Verify `~/.claude-code-docs/paths_manifest.json` exists. If not:
> Documentation not found. Run this in Claude Code to install:
> ```
> /plugin marketplace add costiash/claude-code-docs
> /plugin install claude-docs@claude-code-docs
> ```

### Step 2: Check freshness

Two signals — when the manifest was last generated (server-side), and when the clone last pulled:
```bash
jq -r '.generated_at' ~/.claude-code-docs/paths_manifest.json          # manifest build time
cd ~/.claude-code-docs && git log -1 --format="%ci %s"                  # clone last updated
```
If the manifest is older than ~24h, the SessionStart hook normally refreshes it on the next
session; a manual refresh is `cd ~/.claude-code-docs && git fetch origin main && git reset --hard origin/main`.

### Step 3: Check the cache status

```bash
~/.claude-code-docs/plugin/scripts/fetch-docs.sh status
```
Reports manifest pages / cached / pending / stale. If pending > 0, suggest `/docs sync`.

### Step 4: Run URL validation (if user asks for it)

Quick spot-check (recommended first), or full scan (1-2 min):
```bash
bash ~/.claude-code-docs/plugin/skills/claude-docs-validate/scripts/validate-paths.sh --quick
bash ~/.claude-code-docs/plugin/skills/claude-docs-validate/scripts/validate-paths.sh
```
These read URLs directly from the manifest. Report the summary (reachable / broken / timed out).
For persistent broken URLs, the upstream page may have moved — report at
https://github.com/costiash/claude-code-docs/issues.

### Step 5: Doc statistics (if user asks for stats/count)

```bash
jq '.pages | length' ~/.claude-code-docs/paths_manifest.json                       # total
````
