What This Skill Does
A CLI utility for generating and verifying cryptographic checksums for files and directories. Supports MD5, SHA1, SHA256, and SHA512 algorithms. JSON output makes results easy to pipe into other scripts.
Works on Windows, macOS, and Linux without requiring coreutils or platform-specific tools like md5sum or shasum.
When to use it
- Verifying a downloaded archive before installing it
- Detecting file changes between two deployments
- Generating checksums for software release artifacts
- Auditing a directory for unexpected file modifications
- Comparing file sets across different machines or environments
Example Workflow
Here's how your AI assistant might use this skill in practice.
User asks: verify that a downloaded release archive matches the published SHA256 hash
- 1Run the checksum tool against the downloaded file with --algo sha256
- 2Capture the output hash string
- 3Compare it against the published hash from the release page
- 4Report whether the hashes match or differ
