Dead Code Report

knip v5 scan results (auto-detects Next.js entry points — pages, layouts, API routes, middleware are not flagged):

!npx knip@5 --no-color 2>&1 || echo "(knip exited with errors — see output above)"

---

Node Version Note

!node --version

knip@6+ requires Node ≥20.19. If the Node version above is older, the skill pins to knip@5 automatically.

Instructions

Analyse the knip output above and produce a structured report with three sections. For each finding, say what it is, whether it looks like real dead code or a false positive, and what action to take.

---

Section 1 — Unused Files

Files that are never imported by any other module. These are the highest-priority findings.

Known false-positive patterns for this project — skip these:

• Files under src/app/ (Next.js entry points — pages, layouts, route handlers, middleware)
• src/proxy.ts / src/middleware.ts (Next.js middleware, auto-executed)
• Test files (*.test.ts, *.spec.ts)

For each real unused file: name it, describe what it contains, and recommend deleting it or wiring it up.

---

Section 2 — Unused Exports

Named exports that no other module imports. These are lower priority — the file itself is live, but the export is dead weight.

Known false-positive patterns for this project — skip these:

• signIn / signOut re-exports from src/lib/auth.ts — used by Auth.js internally via the auth config object
• Query key objects (*Keys) — these are exported for cache invalidation and may not show up in static analysis
• redirect from src/i18n/navigation.ts — re-exported from next-intl, may be used conditionally

For each real unused export: name it, show the file:line, and recommend either removing the export or deleting the function/type entirely if nothing else in the file is used.

---

Section 3 — Unlisted / Unused Dependencies

Unlisted = used in code but not declared in package.json (transitive dep leak — fragile). Unused = declared in package.json but never imported in the scanned source.

Known false-positive patterns for this project — skip these:

• postcss unlisted — it's a peer dependency of @tailwindcss/postcss, not needed as a direct dep

For each real finding: name the package, show where it is/isn't used, and recommend adding it explicitly or removing it.

---

Summary

End with a concise punch list:

• Delete — files/exports that are clearly dead
• Investigate — findings that might be false positives requiring a closer look
• Skip — confirmed false positives and why
