Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00037 | $0.00392 |
| Opus 5.5 | $0.00015 | $0.00157 |
| Sonnet 5.5 | $0.00007 | $0.00078 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
nextjs-fullstack 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 1mo 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.
What it actually says
Next.js Fullstack
Ship Next.js features with correct boundaries between server, client, data, and UI.
Grok Build Mode
- Use Plan Mode for routing, auth, persistence, caching, or data-fetching changes.
- Use subagents for broad changes:
routes: app router structure, layouts, metadata.data: DB queries, server actions, validation.client: components, state, forms, accessibility.tests: unit/e2e/build verification.
- Arena-style comparison: compare server action vs API route vs client-only approaches and choose by security, simplicity, and cache behavior.
Workflow
- Detect Next version, package manager, styling, auth, DB, and test setup.
- Keep server-only code out of client components.
- Validate inputs on the server.
- Respect existing caching/revalidation patterns.
- Add loading/error/empty states.
- Run the narrowest relevant checks:
npm run lintnpm run typechecknpm run build- project tests.
Rules
- Do not leak secrets into
NEXT_PUBLIC_*. - Avoid unnecessary client components.
- Do not mutate data without auth and ownership checks.
- Keep forms progressive and resilient.
- Use existing UI primitives and route conventions.
Example Prompts
Use nextjs-fullstack. Plan a server-action implementation for this feature, including validation, auth, tests, and loading/error UI.
Review this Next.js diff for server/client boundary bugs and cache invalidation issues.
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.

nextjs-fullstack is a skill published in the GitHub repository DominikTobureto/awesome-grok-build (67 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 392 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
