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 mastra-ai/mastra at 788ceed5b3.

    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

The e2e-tests-studio skill provides a dedicated environment for designing, executing, and managing end-to-end testing workflows within the Mastra framework. It enables AI agents to validate complex application flows by simulating user interactions across the entire system lifecycle.

When to use it

  • Regression validation: Automatically verify that recent code changes did not break critical user journeys in production-like environments.
  • Integration verification: Test how different microservices or third-party APIs interact during a complete transaction flow.
  • CI/CD pipelines: Integrate automated end-to-end checks into deployment workflows to catch integration errors before release.
  • User experience simulation: Replicate specific multi-step user scenarios to ensure the application behaves as expected from start to finish.

Key capabilities

  • End-to-end test orchestration within Mastra
  • Full lifecycle validation of application flows
  • Automated execution of complex user interaction sequences
  • Integration with Mastra's agent testing infrastructure

Example prompts

  • "Run an end-to-end test for the checkout process starting from product selection to payment confirmation."
  • "Simulate a multi-step user journey involving login, profile update, and order placement using e2e tests."
  • "Execute automated validation of the new API integration flow across all dependent services."

Tips & gotchas

Ensure your application environment is stable before running end-to-end suites, as these tests are sensitive to external dependencies. Limit concurrent test executions if your infrastructure cannot handle full-scale load during validation cycles.
