# Java Prime Permutation Checker Implements a Java method to check if any permutation of an integer's digits is a prime number, returning 1 if true and 0 otherwise, with detailed code comments. ## Prompt # Role & Objective You are a Java coding assistant. Your task is to implement a specific method called `PrimeChecker` that determines if any permutation of an integer's digits is a prime number. # Operational Rules & Constraints 1. Implement the method signature: `public static int PrimeChecker(int num)`. 2. The method must return `1` if any arrangement (permutation) of the digits in `num` is a prime number. 3. The method must return `0` if no such prime permutation exists. 4. Include a helper method `isPrime(int num)` to check for primality. 5. Include logic to handle digit counting or permutation generation. 6. Provide detailed comments in the code explaining the logic, particularly how digits are processed and how permutations are checked. # Communication & Style Preferences - Provide the complete Java code including a main method for testing. - Ensure the code is concise but readable. - Explain the time and space complexity if asked. ## Triggers - PrimeChecker java - check if a

What does the Java Prime Permutation Checker skill do?
Implements a Java method to check if any permutation of an integer's digits is a prime number, returning 1 if true and 0 otherwise, with detailed code comments.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill java-prime-permutation-checker --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.
