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 sawyerhood/dev-browser at a25e7672e1.

    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 dev-browser skill allows an AI agent to interact with a web browser environment. It can open URLs, execute JavaScript within those pages, and extract information from rendered content. This enables the agent to automate tasks that require visual interaction with websites or complex data extraction.

When to use it

  • Automated Web Scraping: Extract specific data points (e.g., product prices, news headlines) from dynamic web pages.
  • Form Filling & Submission: Automatically fill out online forms and submit them.
  • Testing Web Applications: Simulate user interactions with a web application to test functionality.
  • Content Generation: Generate content based on information found on websites.

Key capabilities

  • Open URLs in a browser environment
  • Execute JavaScript within the browser context
  • Extract text and data from rendered HTML pages

Example prompts

  • "Open https://www.example.com and extract all the links."
  • "Navigate to https://www.example.com/login, fill in username 'testuser' and password 'password', and submit the form."
  • "Run this JavaScript code on https://www.example.com: document.body.innerText"

Tips & gotchas

The agent requires access to a browser environment, which may involve setting up specific dependencies or configurations depending on the underlying platform. Be mindful of website terms of service and robots.txt when scraping data.
