project-structure

A set of React coding patterns for applications built with Vite or Next.js. It covers component style, page rendering, styling, accessibility, translations, effects, and reusable hooks.

In plain words
What is it for?
Use it when writing React components, Next.js pages, interactive behaviour, Tailwind styles, translations, and shared hooks.
Why use it?
It prevents common inconsistencies, such as mixing server and browser code incorrectly or putting user-visible text directly inside interface components.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 299 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 yesterday.

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

Project structure

  • shadcn UI → src/components/ui/ (primitives only)
  • Domain presentational UI → src/components/[domain]/
  • Shared UI (≥2 domains) → src/components/shared/
  • Feature modules → src/features/[domain]/ (same *.types.ts / *.constants.ts layout as components)
  • HTTP + Zod → src/fetchers/[domain]/
  • Tanstack Query hooks → src/hooks/[domain]/ (usable from components and features)
  • Context + app-wide providers → src/providers/ (compose in AppProviders)
  • shadcn cnsrc/lib/utils.ts
  • Locale config → src/i18n/; catalogs → src/messages/
  • Global utils/types/constants → src/utils, src/types, src/constants (utils usable from components/features)
  • E2E → e2e/[domain]/[path].spec.ts
  • Next.js routes → src/app/; Vite screens → src/pages/

Do not call Tanstack Query/fetch directly from components — go through hooks / fetchers (usually via a feature). Details: docs/frontend/conventions/PROJECT_STRUCTURE.md

Changes

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.

project-structure is a cursor rule published in the GitHub repository ddebixx/frontend-template (3 stars, last pushed 24d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 299 tokens. 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.
