Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned fatih-developer/fth-skills at f0d82e9b4f.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

The schema-diff-analyzer skill compares two JSON schemas and identifies the differences between them. It highlights additions, deletions, and modifications to properties within the schemas. This allows for a clear understanding of changes made during schema evolution or versioning.

When to use it

  • Schema Version Control: Compare a current schema with an older version to understand what changed before deploying updates.
  • API Migration: Analyze differences between API schema versions to plan and execute migrations smoothly.
  • Data Validation Updates: Determine the impact of changes to data validation rules defined in JSON schemas.
  • Collaboration & Review: Facilitate understanding among developers when reviewing or collaborating on schema modifications.

Key capabilities

  • Schema comparison
  • Identification of added properties
  • Identification of deleted properties
  • Detection of modified property definitions

Example prompts

  • "Compare these two schemas: [schema 1] and [schema 2]"
  • "Show me the differences between schema version 1.0 and 1.1."
  • "Analyze this JSON schema and tell me what properties have been changed."

Tips & gotchas

The skill requires valid JSON Schema inputs to function correctly. Providing invalid or malformed schemas will result in errors.
