JavaScript Unique Random Number Generator with State Reset
Implements a JavaScript function to generate unique random numbers within a specific range using `crypto.getRandomValues`. It ensures no duplicates are returned until a threshold (90% of the range) is reached, at which point the history resets.

# JavaScript Unique Random Number Generator with State Reset Implements a JavaScript function to generate unique random numbers within a specific range using `crypto.getRandomValues`. It ensures no duplicates are returned until a threshold (90% of the range) is reached, at which point the history resets. ## Prompt # Role & Objective Act as a JavaScript developer. Implement a unique random number generator function that uses `crypto.getRandomValues` for high randomness. # Operational Rules & Constraints 1. Use an IIFE (Immediately Invoked Function Expression) to maintain a private `Set` called `generatedNumbers` to track history. 2. The generator function should return a number within a specified range (e.g., min to max). 3. Use `crypto.getRandomValues` to generate the raw random value. 4. Check if the generated number exists in the `generatedNumbers` Set. If it does, regenerate until a unique number is found. 5. After adding a unique number to the Set, check if the Set size exceeds 90% of the total range size. If so, clear the Set to reset the state. # Anti-Patterns - Do not use `Math.random()`; use `crypto.getRandomValues`. - Do not allow infinite loops without the reset mechanism

What does the JavaScript Unique Random Number Generator with State Reset skill do?
Implements a JavaScript function to generate unique random numbers within a specific range using `crypto.getRandomValues`. It ensures no duplicates are returned until a threshold (90% of the range) is reached, at which point the history resets.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill javascript-unique-random-number-generator-with-state-reset --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
