Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Repository Overview

TanStack AI is a type-safe, provider-agnostic AI SDK for building AI-powered applications. The repository is a **pnpm monorepo** managed with **Nx** that includes TypeScript packages, plus multiple framework examples.

**Docs skill (mandatory).** Before planning, writing, editing, or reorganizing anything under `docs/`, load `.claude/skills/docs/SKILL.md` and follow it. Do not write docs without it. See **Documentation** below for TanStack-specific rules that also apply.

**PR description skill (mandatory).** Before `gh pr create`, and after an agent `git push` on a branch that already has an open PR, load `.claude/skills/pr-description/SKILL.md` and follow it. Do not invent the title and body from memory. A **fix** PR must pass `bugfix-pr` before this skill posts.

How to install

The exact contents, by fingerprint
mdr add tanstack/ai/CLAUDE.md@sha256:7900218e4b604439

The line at the top of this page pins the label git:20261106.2641779, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
