typescript

typescript is a cursor rule for Cursor from inboxpraveen/Minimize-Cursor-Cost. It costs 0 tokens per session (349 once invoked), scanned A, original, Apache-2.0.

Coding rules for TypeScript and JavaScript files, including React code. They guide the agent to follow the project's existing style and type choices.

In plain words
What is it for?
Use it when changing functions, React components, imports, or types in TypeScript and JavaScript projects.
Why use it?
It reduces inconsistent formatting, unnecessary type changes, and overly broad code examples. It also helps keep edits focused on the requested parts.

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 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

TypeScript/JavaScript Rules

Style Matching

  • Match existing: semicolons or not, single vs double quotes, trailing commas
  • Match existing: function declarations vs arrow functions
  • Match existing: interface vs type alias preference
  • Do not add as const or other TS niceties if the file doesn't already use them

Output Format

  • Single function change → show only that function
  • React component change → show only the changed JSX section + affected hooks
  • Use // ... rest of component to skip unchanged JSX

Types

  • Reuse existing project types — check for them before creating new ones
  • Inline types for one-use cases: (items: string[]) => not a new interface
  • Don't add unknown or overly defensive types unless the existing code does

Imports

  • Show only new/changed import lines
  • Group: external libs → internal modules → types (match existing grouping)

React Specifics

  • Don't rename props or state variables
  • Don't extract new components unless asked
  • Don't add useMemo/useCallback optimizations unless the task is performance
  • Don't switch between controlled/uncontrolled input patterns

Never

  • Don't convert .js to .ts unless asked
  • Don't add JSDoc to functions that don't have it
  • Don't wrap with try/catch unless existing similar functions have it
  • Don't add default exports if the file uses named exports

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.
