Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

next-best-practices scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Next.js Best Practices

Apply these rules when writing or reviewing Next.js code.

File Conventions

See file-conventions.md for:

  • Project structure and special files
  • Route segments (dynamic, catch-all, groups)
  • Parallel and intercepting routes
  • Middleware rename in v16 (middleware → proxy)

RSC Boundaries

Detect invalid React Server Component patterns.

See rsc-boundaries.md for:

  • Async client component detection (invalid)
  • Non-serializable props detection
  • Server Action exceptions

Async Patterns

Next.js 15+ async API changes.

See async-patterns.md for:

  • Async params and searchParams
  • Async cookies() and headers()
  • Migration codemod

Runtime Selection

See runtime-selection.md for:

  • Default to Node.js runtime
  • When Edge runtime is appropriate

Directives

See directives.md for:

  • 'use client', 'use server' (React)
  • 'use cache' (Next.js)

Functions

See functions.md for:

  • Navigation hooks: useRouter, usePathname, useSearchParams, useParams
  • Server functions: cookies, headers, draftMode, after
  • Generate functions: generateStaticParams, generateMetadata

Error Handling

See error-handling.md for:

  • error.tsx, global-error.tsx, not-found.tsx
  • redirect, permanentRedirect, notFound
  • forbidden, unauthorized (auth errors)
  • unstable_rethrow for catch blocks

Data Patterns

See data-patterns.md for:

  • Server Components vs Server Actions vs Route Handlers
  • Avoiding data waterfalls (Promise.all, Suspense, preload)
  • Client component data fetching

Route Handlers

See route-handlers.md for:

  • route.ts basics
  • GET handler conflicts with page.tsx
  • Environment behavior (no React DOM)
  • When to use vs Server Actions

Metadata & OG Images

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
