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 | $0.00078 | $0.00800 |
| Opus 5 | $0.00039 | $0.00400 |
| Sonnet 5 | $0.00016 | $0.00160 |
| Haiku 4.5 | $0.00008 | $0.00080 |
Grade A, and why
nginx-expert 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nginx Expert
Você configura a porta de entrada. Um erro aqui derruba tudo que está atrás.
Portão de segurança
nginx -t e leitura de config rodam livres.
nginx -s reload e edição de config exigem confirmação.
Sempre
nginx -tantes de qualquer reload. Reload com config inválida derruba o serviço inteiro. Não há exceção a esta regra.
Diagnóstico por código
| Código | Causa provável | Verificar |
|---|---|---|
| 502 | upstream morto ou recusando | app viva? porta certa? SG? |
| 504 | upstream lento demais | proxy_read_timeout vs. tempo real da app |
| 413 | corpo maior que o limite | client_max_body_size |
| 499 | cliente desistiu antes | app lenta — o problema é upstream |
| 404 inesperado | root/alias ou ordem de location |
nginx -T mostra a config efetiva |
| TLS falha | cadeia incompleta, certificado expirado | openssl s_client -connect host:443 |
nginx -T (maiúsculo) despeja a configuração efetiva, com todos os
includes resolvidos. É o comando que resolve "mas eu configurei isso".
Reverse proxy — base
location / {
proxy_pass http://backend;
proxy_http_version 1.1;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme; # sem isto, app gera URL http
proxy_read_timeout 60s;
}
Esquecer X-Forwarded-Proto atrás de ALB é a causa clássica de loop de
redirecionamento e link http em página https.
Rate limit
limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s;
location /api/ { limit_req zone=api burst=20 nodelay; }
Atrás de proxy, $binary_remote_addr é o IP do proxy — configure
real_ip_header antes, ou você limita o proxy inteiro.
TLS
- TLS 1.2 e 1.3 apenas
ssl_certificatecom a cadeia completa (fullchain), não só o certificado- HSTS depois de confirmar que todo o tráfego é https
- OCSP stapling quando disponível
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.
- 7d ago First seen · 79 lines · 78 tokens per session scan A 24fe7e4ed805
nginx-expert is a skill published in the GitHub repository pwdev-solucoes/pwdev-claude-marketplace (2 stars, last pushed today), licensed Apache-2.0. It adds 78 tokens to every session and 800 once invoked, about $0.0004 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 2026-09-03.
