ai-persistence/build-cloudflare-artifact-store skillA

ai-persistence/build-cloudflare-artifact-store is agent-read markdown (skill) from tanstack/ai: Use when a Cloudflare Worker needs durable byte storage for TanStack AI generated media (images, audio, video, transcripts) — writes a BlobStore backed by R2 and an ArtifactStore backed by D1, composes them onto the generation persistence so withGenerationPersistence persists artifact bytes, and serves them back from a Worker GET route. Includes one-line sketches for S3, GCS, Vercel Blob, Supabase, and a dev filesystem BlobStore..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add tanstack/ai/ai-persistence/build-cloudflare-artifact-store@git:20260909.53e2ec0
Exact content
mdr add tanstack/ai/ai-persistence/build-cloudflare-artifact-store@sha256:fd895225b1842239

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
