TanStack AI is a TypeScript SDK for building applications that stream AI responses, call tools, run agents, produce structured output, and handle multimodal or realtime interactions. Developers use it across frameworks and AI providers through shared typed interfaces and provider adapters. The catalogue entries are add-ons for working with this SDK.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 10 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00068 | $0.03706 |
| Opus 5.5 | $0.00027 | $0.01482 |
| Sonnet 5.5 | $0.00014 | $0.00741 |
| Haiku 4.5 | $0.00007 | $0.00371 |
Grade A, and why
ai-persistence/build-cloudflare-adapter scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
| How `env` reaches code | the Worker `fetch(request, env)`, or an async-local helper (`getDb()`, `getCloudflareContext()`) | Whether the factory takes `env` or reads a helper | How it starts
The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cloudflare Chat Persistence
The deliverable is one file in the Worker — src/lib/chat-persistence.ts —
exporting a factory that builds a ChatPersistence from the request's D1
binding, plus (when the app needs coordination) a Durable Object lock store.
Tables go into the app's existing migrations/ directory and are applied with
wrangler d1 migrations apply.
Do not create a package or a migration runner. Wrangler already tracks applied migrations; a second bookkeeping table only creates drift.
Read the Store Reference
(docs/persistence/store-reference.md) for the store contracts, and
ai-persistence/stores for the shape rules. This skill covers only
the Cloudflare-specific parts.
1. Read the app before writing anything
| Find | Where to look | What it decides |
|---|---|---|
| D1 binding name | wrangler.jsonc d1_databases[].binding |
env.DB vs env.AI_STATE in the factory |
How env reaches code |
the Worker fetch(request, env), or an async-local helper (getDb(), getCloudflareContext()) |
Whether the factory takes env or reads a helper |
| Drizzle or raw D1 | drizzle-orm in package.json, a src/db/schema.ts |
Which recipe below to follow |
| Migrations dir | wrangler.jsonc migrations_dir, default migrations/ |
Where the new .sql file goes |
| Existing table names | the current migrations / schema | Prefix (chat_*) so nothing collides |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ai-persistence/build-cloudflare-adapter is a skill published in the GitHub repository TanStack/ai (3,336 stars, last pushed yesterday), licensed MIT. It adds 68 tokens to every session and 3,706 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
