project-structure

project-structure is a cursor rule for coding agents from cmaranho/rn-agent-skills. It costs 150 tokens per session, scanned A, original, MIT.

A set of rules for organizing a project's folders, features, and shared code.

In plain words
What is it for?
Use it when adding features, defining module boundaries, separating shared code from feature code, or deciding how a module exposes its public interface.
Why use it?
It reduces confusion about where new code belongs and prevents unrelated modules from depending directly on each other. This makes features easier to change and reuse.

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.

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

project-structure 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 4d 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

Organização do Projeto

  • Separe código compartilhado de código de domínio/feature (ex.: common vs modules).
  • Cada módulo/feature é coeso e autocontido (uma responsabilidade).
  • Estrutura por feature com camadas separadas: dados, estado, UI e telas.
  • UI compartilhada em local comum; UI exclusiva vive dentro do módulo.
  • Sem dependências cruzadas entre módulos irmãos; compartilhe via camada comum.
  • API pública do módulo exposta por barrel (index.ts); sem imports internos profundos.
  • Feature nova segue a estrutura completa; não replique padrões legados em código novo.

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.
