Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 7 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 | $0.00155 | $0.03893 |
| Opus 5 | $0.00077 | $0.01946 |
| Sonnet 5 | $0.00031 | $0.00779 |
| Haiku 4.5 | $0.00015 | $0.00389 |
Grade A, and why
sanity-live-cache-components 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sanity Live + Cache Components
Wires next-sanity into a Next.js 16+ app with cacheComponents: true. Data is fetched with sanityFetch through a single shared 'use cache' boundary (cachedSanity), and <SanityLive> in the root layout revalidates cached content over an EventSource connection to Sanity Content Lake. Visual Editing and Presentation Tool are fully supported when draft mode is enabled.
Read the relevant guide in node_modules/next/dist/docs/ (when available) before writing code. If a guide conflicts with this skill, follow this skill.
This skill assumes familiarity with Cache Components fundamentals — 'use cache', cacheLife, cacheTag, and the cookies/headers/params rule — covered by the Cache Components guide (bundled offline under node_modules/next/dist/docs/). The only Sanity-relevant exception: await draftMode() is allowed inside 'use cache' (Next.js bypasses caching when draft mode is enabled — see the use cache reference).
Where this skill fits
Next.js ships official skills for the framework-generic workflows (see Setting up your project for AI coding agents). This skill covers only the Sanity surface and defers everything else to them. Install them from the Next.js repository:
npx skills add vercel/next.js --skill next-dev-loop
npx skills add vercel/next.js --skill next-cache-components-adoption
npx skills add vercel/next.js --skill next-cache-components-optimizer
npx skills add vercel/next.js --skill next-partial-prefetching-adoption
When their rules apply — blocking-route triage, <Suspense> placement, loading-UI reuse, instant() regression tests, link prefetch audits — follow them; don't re-derive that guidance from here.
Recommended sequence when migrating an app:
next-cache-components-adoption— enablescacheComponents: trueand works the app to a passing build, route by route. Tell it to leave the Sanity surface to this skill:
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

sanity-live-cache-components is a skill published in the GitHub repository sanity-io/next-sanity (951 stars, last pushed today), licensed MIT. It adds 155 tokens to every session and 3,893 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
