Summary

• Clarify that existing fetch and unstable_cache caching can remain in place during Cache Components adoption.
• Preserve routes that previously used dynamic = 'force-static' or dynamic = 'error' instead of leaving them under instant = false, which can move rendering to request time and reduce prefetched UI.
• Update the adoption skill to prioritize those routes in the first migration PR and verify that they still prerender.
• Extend the existing Cache Components adoption eval with static-route contracts and independent cache lifetimes.

Eval results

The updated agent-047-adopt-cache-components eval was attempted with Claude Opus 4.8:

The local runner could not obtain Vercel OIDC credentials. These were infrastructure failures, so no eval criteria ran and no pass rates were produced.

Verification

• pnpm --filter=next build
• Prettier check for all changed Guide, skill, and eval files
• git diff --check origin/canary...HEAD
