Automated safety checks

scanned 11 Oct 2026

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 anthropics/skills at dbd4588f9e.
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 webapp-testing skill enables AI agents to perform automated testing of web applications. It includes capabilities such as executing test scripts, validating user interface elements, and ensuring functionality across different browsers and devices.

When to use it

To verify that a new feature works correctly after deployment.
To run regression tests before releasing an update.
To ensure cross-browser compatibility for a web application.
To automate repetitive testing tasks in continuous integration pipelines.

Key capabilities

Execution of unit, integration, and end-to-end tests
Validation of UI elements and user interactions
Support for multiple browsers and devices
Integration with CI/CD tools

Example prompts

"Run all test cases for the login functionality."
"Check if the checkout process works on Chrome and Firefox."
"Generate a report for failed test cases from the last build."

Tips & gotchas

Ensure that your web application is accessible during testing to avoid connection errors.
Some advanced features may require additional setup or dependencies, such as browser drivers or test frameworks.
