Tokens, turns and time describe resource use, not a dollar price.
One of 8 test cases the skill fixed. Same model, same prompt, with and without the skill.
We are configuring `next.config.ts` for a new Next.js application that wants to leverage Partial Prerendering and granular component-level caching primitives like `'use cache'`. Show the exact `next.config.ts` file needed to enable this feature.

| The Next.js config object sets cacheComponents to true. | Missed | Passed |
The instructions your model reads when the skill loads.
Auto-activation: This skill activates automatically in projects with
cacheComponents: truein next.config.
When starting work in a Next.js project, check if Cache Components are enabled:
# Check next.config.ts or next.config.js for cacheComponents
grep -r "cacheComponents" next.config.* 2>/dev/null
If cacheComponents: true is found, apply this skill's patterns proactively when:
Cache Components enable Partial Prerendering (PPR) - mixing static HTML shells with dynamic streaming content for optimal performance.
Cache Components represents a shift from segment configuration to compositional code:
| Before (Deprecated) | After (Cache Components) |
|---|---|
export const revalidate = 3600 | cacheLife('hours') inside 'use cache' |
export const dynamic = 'force-static' | Use 'use cache' and Suspense boundaries |
| All-or-nothing static/dynamic | Granular: static shell + cached + dynamic |
Key Principle: Components co-locate their caching, not just their data. Next.js provides build-time feedback to guide you toward optimal patterns.
