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

typescript-react-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 3d 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.

TypeScript React Patterns

Type-safe React with TypeScript. Contains 33 rules across 7 categories covering component typing, hooks, event handling, refs, generics, context, and utility types.

Metadata

  • Version: 2.0.0
  • Rule Count: 33 rules across 7 categories
  • License: MIT

When to Apply

Reference these guidelines when:

  • Typing React component props
  • Creating custom hooks with TypeScript
  • Handling events with proper types
  • Working with refs (DOM, mutable, imperative)
  • Building generic, reusable components
  • Setting up typed Context providers
  • Fixing TypeScript errors in React code

Rule Categories by Priority

Priority Category Impact Prefix
1 Component Typing CRITICAL comp-
2 Hook Typing CRITICAL hook-
3 Event Handling HIGH event-
4 Ref Typing HIGH ref-
5 Generic Components MEDIUM generic-
6 Context & State MEDIUM ctx-
7 Utility Types LOW util-

Quick Reference

1. Component Typing (CRITICAL)

  • comp-props-interface - Use interface for props, type for unions
  • comp-children-types - Correct children typing (ReactNode, ReactElement)
  • comp-default-props - Default props with destructuring defaults
  • comp-forward-ref - Typing forwardRef components
  • comp-polymorphic - Polymorphic "as" prop typing
  • comp-fc-vs-function - Function declaration vs React.FC
  • comp-display-name - Display names for debugging
  • comp-rest-props - Spreading rest props with proper types

2. Hook Typing (CRITICAL)

  • hook-usestate - useState with proper generic types
  • hook-useref - useRef for DOM elements and mutable values
  • hook-use-reducer - useReducer with discriminated union actions
  • hook-use-callback - useCallback with typed parameters
  • hook-use-memo - useMemo with typed return values
  • hook-use-context - useContext with null checking
  • hook-custom-hooks - Custom hook return types
  • hook-generic-hooks - Generic custom hooks

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.
