Live repository

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 patricio0312rev/skills at 79ea6af485.

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

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables AI agents to generate and execute contract tests, ensuring that different services in a distributed system adhere to their agreed-upon interfaces. It automates the verification of API contracts to prevent breaking changes during development or deployment cycles.

When to use it

  • Microservices Integration: Validate interactions between independent services before merging code into a shared repository.
  • API Evolution: Ensure backward compatibility when updating request/response schemas in an existing service ecosystem.
  • CI/CD Pipelines: Integrate automated contract checks into build processes to catch integration failures early.
  • Third-Party Dependencies: Verify that external library updates or partner API changes do not violate internal usage expectations.

Key capabilities

  • Generates contract test suites based on defined service agreements.
  • Executes tests against actual service implementations to detect mismatches.
  • Provides clear feedback on which specific contract clauses are violated.
  • Supports both request and response validation logic.

Example prompts

  • "Create a contract test suite for my user authentication microservice that validates the new token response format."
  • "Run contract tests against the payment gateway API to ensure our recent schema update didn't break existing integrations."
  • "Generate a report showing which service endpoints are failing their current contract agreements in the staging environment."

Tips & gotchas

Ensure your services have well-defined interface documentation or OpenAPI specs available, as the skill relies on these definitions to generate accurate tests. Limit test execution frequency during high-load production windows to avoid unnecessary network overhead from repeated validation calls.
