Calculate the hash of a given text.
— the description by Google AI Edge

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The calculate-hash skill provides a straightforward mechanism to compute the hash of any given text string. By leveraging a specific JavaScript execution environment, it processes input text and returns the corresponding hash value, facilitating data integrity checks or identifier generation.

What it does

  • Computes a hash value for a specified text string.
  • Uses a dedicated script to perform the hashing operation.
  • Accepts input text via a structured JSON format.

When to use it

  • When you need to generate a unique hash for a piece of text.
  • When performing data verification or creating identifiers.
  • When you require a programmatic way to hash strings within an agent workflow.

Advantages

  • Provides a consistent and repeatable hashing process.
  • Simple integration into existing agent workflows.
  • Supports arbitrary text input for flexible use cases.

Usage examples

“Calculate hash of 'hello world'”
The agent returns the computed hash value for the string 'hello world'.
“What is the hash of the text 'data-integrity-check'?”
The agent processes the text and provides the resulting hash string.
