# Query Docs And Library Metadata

Use this skill to collect authoritative context before code generation or integration selection.

## Setup

```bash
npx @tanstack/cli libraries --json
```

## Core Patterns

### Resolve valid library ids before doc fetch

```bash
npx @tanstack/cli libraries --json
```

### Fetch a specific docs page with explicit version

```bash
# Syntax: tanstack doc <library-id> <path> [--docs-version <version>]
npx @tanstack/cli doc router framework/react/guide/routing
npx @tanstack/cli doc router framework/react/guide/routing --docs-version latest
```

### Search docs for implementation targets

```bash
npx @tanstack/cli search-docs "server functions" --library start --json
```

## Common Mistakes

### HIGH Use invalid library id/version/path for doc fetch

Wrong:
```bash
# Wrong: --library and --version are not flags on doc; path must not include /docs/ prefix
npx @tanstack/cli doc --library router --version latest --path /docs/framework/react/guide/routing
```

Correct:
```bash
# Step 1: resolve a valid library id
npx @tanstack/cli libraries --json
# Step 2: fetch using positional args — library id then doc path (no /docs/ prefix)
npx @tanstack/cli doc router framework/react/guide/routing
```

`doc` takes `<library>` and `<path>` as positional arguments (not flags), and the path must not include a leading `/docs/` segment. Use `--docs-version` (not `--version`) to pin a specific version.

### MEDIUM Rely on deprecated create alias for discovery

Wrong:
```bash
npx create-tsrouter-app --list-add-ons
```

Correct:
```bash
npx @tanstack/cli create --list-add-ons --json
```

Legacy alias workflows can produce confusing outputs that do not match current CLI discovery behavior. Fixed in newer versions, but agents trained on older examples may still generate this pattern.

### HIGH Tension: Single-command convenience vs integration precision

This domain's patterns conflict with create-app-scaffold and choose-ecosystem-integrations. Skipping discovery to run one-shot scaffold commands tends to lock in plausible defaults that miss architecture constraints.
