tanstack-best-practices

tanstack-best-practices is a skill for Claude Code, Codex from zama-ai/sdk. It costs 160 tokens per session (3,736 once invoked), scanned A, original, BSD-3-Clause-Clear.

A set of coding guidelines for building TanStack Query hooks. TanStack Query is a library for fetching, caching, and updating data in web applications; hooks are reusable functions that connect that library to application code.

In plain words
What is it for?
Use it when writing useQuery or useMutation hooks, designing cache identity and invalidation rules, or creating reusable query-option factories.
Why use it?
It helps keep data-fetching hooks consistent and prevents mistakes in cache keys, query options, and cache updates.

Token cost

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.

Security

Grade A, and why

tanstack-best-practices scanned grade A with 0 findings 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
