Two big months: Next.js Cache Components via next-sanity v13, Markdown content negotiation, a shared blocks package and agent skills. Here it is.

If you only read one of these posts, read this one. May and June reshaped how the starter caches, renders and talks to agents.

## Cache Components via next-sanity v13

The starter adopted Next.js Cache Components through next-sanity v13, and the Sanity ecosystem was aligned to match. Live tag invalidation was restored for regular visitors, and realtime draft preview now uses `updateTag`. Fresh installs also stopped failing on an empty `generateStaticParams`.

## Markdown for agents

Pages can be served as Markdown, with components kept out of the output. Page-builder surfaces were co-located and the serialiser moved to `@portabletext/markdown`. Agents get clean text, and unknown blocks degrade to nothing.

## Shared packages

Blocks moved into a `sanity-blocks` package and Tailwind config into its own package, with an env example so the template works from a fresh clone. A root type-check task now runs through Turborepo.

## Agent skills

Sanity agent skills and Vercel Labs skills now ship in the repo, so coding agents start with the right conventions.

## Smaller wins

- The SEO site title now comes from Settings instead of being hard-coded.
- The Studio deploys via `appId` rather than the deprecated `studioHost`.
- The FAQ uses native `details` and `summary`, with hardened JSON-LD.
- Open Graph images use a simpler site name and title layout.
- A central container standardises widths across nav, sections and blog.
- Image placeholders are pixelated rather than blurred.
- A cleanup removed manual memoisation and dead code, and fixed accessibility issues.

Serve humans HTML, serve agents Markdown, and cache both properly.
