You Don't Need ISR

Audit a Next.js project's Incremental Static Regeneration (ISR) usage. For each occurrence, classify whether ISR is genuinely the right tool or whether a simpler primitive (SSG + webhook revalidation, SSR + CDN cache headers, on-demand revalidation, client-side fetch, or a beefier build runner) does the same job with less platform lock-in and less complexity. Then walk the user through fixes interactively.

This skill audits, explains, and assists. It is not a refactor bot — bias toward fewer, higher-confidence changes and never auto-fix on uncertainty.

Phase 1: Project Detection

Detect characteristics using Glob and Grep. Skip inapplicable phases silently.
