patterns

patterns is a cursor rule for Cursor from timurgaleev/vibestack. It costs 311 tokens per session, scanned A, original, MIT.

A collection of recurring code structures for API responses, frontend custom hooks, and a repository layer that separates data access from other code. It also describes choosing an existing project skeleton before building new functionality.

In plain words
What is it for?
It helps shape API results, reusable frontend hooks, data-access methods, and plans for starting larger features from an existing foundation.
Why use it?
It gives developers consistent starting points instead of inventing different structures for similar features.

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

patterns 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

Common Patterns

API Response Format

interface ApiResponse<T> {
  success: boolean
  data?: T
  error?: string
  meta?: {
    total: number
    page: number
    limit: number
  }
}

Custom Hooks Pattern

export function useDebounce<T>(value: T, delay: number): T {
  const [debouncedValue, setDebouncedValue] = useState<T>(value)

  useEffect(() => {
    const handler = setTimeout(() => setDebouncedValue(value), delay)
    return () => clearTimeout(handler)
  }, [value, delay])

  return debouncedValue
}

Repository Pattern

interface Repository<T> {
  findAll(filters?: Filters): Promise<T[]>
  findById(id: string): Promise<T | null>
  create(data: CreateDto): Promise<T>
  update(id: string, data: UpdateDto): Promise<T>
  delete(id: string): Promise<void>
}

Skeleton Projects

When implementing new functionality:

  1. Search for battle-tested skeleton projects
  2. Use parallel subagents to evaluate options:
    • Security assessment
    • Extensibility analysis
    • Relevance scoring
    • Implementation planning
  3. Clone best match as foundation
  4. Iterate within proven structure

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.

patterns is a cursor rule published in the GitHub repository timurgaleev/vibestack (6 stars, last pushed yesterday), licensed MIT. It adds 311 tokens to every session, about $0.0016 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 2026-09-19.
