What it does

Web Browse is an agent skill from initializ/forge. Drive a headless browser to navigate pages, read content, click, and fill forms — for sites that need JavaScript rendering or interaction beyond a plain HTTP fetch.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Browser automation and Forms and invoices. It works with JavaScript. The repository describes itself as: Forge is the open-source runtime for Anthropic's Agent Skills standard — built for the agent that runs next to a service, in your environment, on infrastructure you already… The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 3c608d8. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Web Browse loads about 1.1k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 442 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

Web Browse

Drive a real headless browser (Chromium) to accomplish web tasks that a plain http_request cannot: pages that render content with JavaScript, multi-step flows, forms, and anything gated behind a click.

The browser is registered only because this skill declares requires.capabilities: [browser]. All navigation is forced through the agent's egress proxy, so it obeys the same allowlist, SSRF, and DNS-rebinding protections as every other web tool. Add the domains you need to egress_domains; a page that redirects off-allowlist is blocked.

Tools

You drive the browser through six tools. You never see raw HTML — every observation is a compact digest: the page title, URL, a numbered list of interactive elements ([3] input(email) "Work email"), and the start of the page text.

  • browser_navigate {url, wait_ms?} — load a page, get its digest.
  • browser_state {max_elements?, scroll_pages?, scroll_to_index?} — re-read the current page (after it changed on its own, to scroll, or to see more elements). Returns a fresh digest with new indices and generation.
  • browser_click {index, generation} — click the element at index from the latest digest. Returns the resulting page digest.
  • browser_fill {index, text, generation, submit?} — type into an input (or pick a select option by label). submit: true presses Enter. Password and payment fields are refused unless this skill opts in.
  • browser_extract {mode?, selector?, max_chars?, offset?} — pull page content: text (readable markdown, default), links, or html (scoped to a CSS selector). Long content is paginated — pass the offset from the previous call's header to continue.
  • browser_screenshot {full_page?, filename?} — capture a PNG for the user (attached to the reply; you will not see the image). Use only when the user wants a visual — read pages with digests and browser_extract.

Workflow

  1. browser_navigate to the target URL. Read the digest's [N] elements and note the Generation number.
  2. To act, pass that generation to browser_click / browser_fill with the element's index. Every action returns a fresh digest — read it, don't assume the old indices still hold.
  3. If you act on a stale generation (the page navigated or changed), the tool returns an error with a fresh digest — retry using the new indices and generation.
  4. For long articles or tables, browser_extract with mode: text and paginate via offset. Use mode: links to enumerate links.

Notes

  • Indices reset whenever the page changes. Always drive from the most recent digest.
  • The browser keeps no cookies or profile between runs.
  • Before using this skill, add the hostnames this agent may reach to egress_domains in the frontmatter above (real domains, wildcards, or $VAR/${VAR} references expanded from the agent env). It ships empty, so every navigation is blocked until at least one host resolves; production builds also reject an open egress policy.
