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.

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 | $0.00047 | $0.00219 |
| Opus 5 | $0.00023 | $0.00110 |
| Sonnet 5 | $0.00009 | $0.00044 |
| Haiku 4.5 | $0.00005 | $0.00022 |
Grade A, and why
nextjs-security-review 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 6d 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 Security Review
Required Checks
- App Router conventions and server/client boundaries.
- Route handlers and server actions for input validation.
- Auth and authorization checks on sensitive paths.
- Middleware coverage or documented route-level alternatives.
- Rate limiting on public mutation and AI/model routes.
- Security headers and deployment-layer header evidence.
- Environment validation and client/server secret separation.
- Unsafe redirects, SSRF, file uploads, and raw provider error leakage.
- Logging that may expose headers, cookies, tokens, requests, or model/provider errors.
Evidence
Use concrete files such as middleware.ts, app/api/**/route.ts, next.config.*, env modules, tests, and security docs. If a control is missing, say missing rather than assuming it exists elsewhere.
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-security-review is a skill published in the GitHub repository priyanshuchawda/codeaudit (1 stars, last pushed 4mo ago), licensed MIT. It adds 47 tokens to every session and 219 once invoked, about $0.0002 per session on Opus 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 2026-08-31.
