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 | $0.00042 | $0.00443 |
| Opus 5 | $0.00021 | $0.00221 |
| Sonnet 5 | $0.00008 | $0.00089 |
| Haiku 4.5 | $0.00004 | $0.00044 |
Grade A, and why
rn-navigation 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 9d 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
React Native — Navegação
Objetivo
Prover navegação tipada, previsível e escalável entre telas.
Quando utilizar
- Adicionar/registrar uma tela, stack, tab ou drawer.
- Passar e ler parâmetros de rota com segurança de tipos.
- Configurar deep linking ou fluxos autenticado vs público.
Conhecimentos necessários
- Biblioteca de navegação do projeto (ex.: React Navigation) e seus navigators.
- Tipagem da lista de parâmetros de rota (
ParamList). - Gate de autenticação (rotas públicas vs privadas).
- Deep linking e configuração de linking.
Fluxo de execução
- Defina a chave da rota e seus params no tipo central de rotas (
ParamList). - Crie a tela e, se houver padrão, uma factory/registro consistente.
- Registre a tela no navigator correto (público vs privado).
- Navegue com params tipados; leia params com hook tipado.
- Atualize o mapeamento de deep link se a rota for endereçável.
Boas práticas
- Nome de rota único e centralizado; sem strings mágicas espalhadas.
- Params serializáveis e mínimos (passe IDs, não objetos grandes).
- Telas finas: lógica no hook de tela, não no componente de rota.
- Padronize wrappers/headers via factory reutilizável.
Armadilhas comuns
- Rota registrada com nome divergente do tipo → erro só em runtime.
- Passar objetos não serializáveis nos params.
- Lógica de navegação acoplada a regra de negócio.
- Deep link sem tratar o estado não autenticado.
Critérios de sucesso
- Navegar para rota/params inexistentes não compila.
- Telas registradas e alcançáveis; deep links funcionam.
- Sem duplicação de definição de rota.
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.

rn-navigation is a skill published in the GitHub repository cmaranho/rn-agent-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 42 tokens to every session and 443 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.
