Query Docs And Library Metadata

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

Setup

npx @tanstack/cli libraries --json

Core Patterns

Resolve valid library ids before doc fetch

npx @tanstack/cli libraries --json

Fetch a specific docs page with explicit version

# 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

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

Common Mistakes

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

Wrong:

# 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:

# 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:

npx create-tsrouter-app --list-add-ons

Correct:

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.
