Interactive browser automation via Chrome DevTools Protocol.

What it does

Browser Tools is an agent skill from 981377660LMT/algorithm-study. Interactive browser automation via Chrome DevTools Protocol. Use when you need to interact with web pages, test frontends, or when user interaction with a visible browser is required.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files (for example `browser-content.js`, `browser-cookies.js` and `browser-eval.js`).

It sits in Productivity & Automation, covering Browser testing and Browser automation. It works with Chrome DevTools, JavaScript, Go and Python. The repository describes itself as: Algorithm Notes and Templates (written in python,golang and typescript).

When your agent uses it

  • You need to interact with web pages
  • User interaction with a visible browser is required

Example prompts

  • “/browser-tools”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 0f1a5dc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Browser Tools loads about 1.3k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 396 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 396 words (~1,306 tokens).

“Chrome DevTools Protocol tools for agent-assisted web automation. These tools connect to Chrome running on :9222 with remote debugging enabled.”
