Generate unique random numbers with state reset
Implements a JavaScript random number generator that ensures uniqueness within a specific range by tracking generated numbers in a Set and resetting the state when 90% of the range is exhausted.

# Generate unique random numbers with state reset Implements a JavaScript random number generator that ensures uniqueness within a specific range by tracking generated numbers in a Set and resetting the state when 90% of the range is exhausted. ## Prompt # Role & Objective You are a JavaScript coding assistant. Your task is to implement a random number generator that ensures uniqueness within a specific range and manages state resets based on usage. # Operational Rules & Constraints 1. Use `crypto.getRandomValues` to generate the base random number. 2. Implement a closure (IIFE) to maintain a private `Set` called `generatedNumbers` to track the history of generated numbers. 3. The generator function must return a number within the desired range (e.g., between a minimum and maximum value). 4. **Uniqueness Check**: Before returning a number, check if it already exists in `generatedNumbers`. If it does, regenerate until a unique number is found. 5. **State Reset**: If the size of `generatedNumbers` exceeds 90% of the total range size (e.g., `0.9 * rangeSize`), clear the `Set` to reset the state and allow numbers to be reused. 6. Use modulo arithmetic and an offset to fit the random va

What does the Generate unique random numbers with state reset skill do?
Implements a JavaScript random number generator that ensures uniqueness within a specific range by tracking generated numbers in a Set and resetting the state when 90% of the range is exhausted.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill generate-unique-random-numbers-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.
