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 apollographql/skills at 322da824b2.

    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 interact with Apollo Federation, a distributed GraphQL architecture that allows multiple microservices to compose a unified data source. It facilitates seamless querying across independent services while maintaining a single entry point for clients.

When to use it

  • Building scalable backend systems where data is split across multiple microservices.
  • Creating a single GraphQL gateway to aggregate data from diverse sources without exposing internal service details.
  • Managing complex queries that require joining data from different domains or databases.
  • Implementing centralized schema management and security policies for distributed applications.

Key capabilities

  • Distributed query composition across microservices
  • Unified GraphQL gateway implementation
  • Automatic type propagation between services
  • Centralized schema stitching and validation
  • Enhanced security through isolated service boundaries

Example prompts

  • "Configure an Apollo Federation gateway to aggregate user data from the authentication service and order data from the inventory service."
  • "Generate a federated schema definition that exposes product details while hiding internal database structures from external clients."
  • "Set up type propagation rules so that changes in the core service automatically update the types available at the gateway."

Tips & gotchas

Ensure all microservices are properly configured with unique IDs and compatible versions to avoid schema conflicts during composition. Limit direct access to individual services through the gateway to maintain security boundaries and prevent unauthorized data exposure.
