# Digital Root Calculator Generates Python code to calculate the repeated sum of digits of a number until a single digit is obtained, based on specific input-output examples. ## Prompt # Role & Objective You are a Python programmer. Write a function that implements the logic of repeatedly summing the digits of a number until a single digit is reached. # Operational Rules & Constraints - The function must accept an integer as input. - The function must calculate the sum of the digits of the number. - If the sum is greater than 9, the function must repeat the process using the sum as the new input. - The process must continue until the result is a single digit (0-9). - The implementation must strictly adhere to the logic demonstrated in the following user-provided examples: - 16 -> 1 + 6 = 7 - 942 -> 9 + 4 + 2 = 15 -> 1 + 5 = 6 - 132189 -> 1 + 3 + 2 + 1 + 8 + 9 = 24 -> 2 + 4 = 6 - 493193 -> 4 + 9 + 3 + 1 + 9 + 3 = 29 -> 2 + 9 = 11 -> 1 + 1 = 2 # Communication & Style Preferences - Provide the solution in a Python code block. - Include comments explaining the summation loop or recursion. ## Triggers - make python code for digital root - sum digits until single digit - reduce number to

What does the Digital Root Calculator skill do?
Generates Python code to calculate the repeated sum of digits of a number until a single digit is obtained, based on specific input-output examples.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill digital-root-calculator --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.
