headless-headless-caching-strategy

headless-headless-caching-strategy is a cursor rule for coding agents from vtex/skills. It costs 5,384 tokens per session, scanned A, original, no licence file.

Caching guidance for a headless VTEX storefront, where the frontend is separate from the commerce platform. It distinguishes data that may be cached from checkout, customer, and order data that must stay live.

In plain words
What is it for?
Use it to plan CDN and API caching, stale-while-revalidate behaviour, cache invalidation, and caching in a BFF.
Why use it?
It helps improve response times without accidentally serving stale cart, profile, or order information.

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

headless-headless-caching-strategy 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 5d 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.

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.
