Skyvern Browser Automation

What it does

When your agent uses it

• Scraping a dynamic page that a plain fetch cannot render
• Filling out and submitting a web form automatically
• Logging into a site and extracting data behind the login
• Turning a repeated multi-page browser task into a reusable workflow
• Working out why a saved browser automation keeps failing

Example prompts

• “Log into the supplier portal and pull the table of open invoices.”
• “Check whether I am still logged in to the admin dashboard.”
• “Build a workflow that fills the three-page signup form and run it.”
• “My Skyvern automation fails on the checkout step, find out why.”

Requirements

• The skyvern CLI, run through Bash
• Pre-approved tools (allowed-tools): Bash(skyvern:*)

Workflow steps

6 steps, taken from the step headings in SKILL.md.

1. 1Classify Your Task (ALWAYS do this first)
2. 2Apply These Decision Rules
3. 3Create a Session
4. 4Execute by Classification
5. 5Verify
6. 6Error Recovery

What it can do on your machine

Read from SKILL.md and the folder at commit f5f3f28. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves these tools, so the agent can use them without asking each time:

  • Bash(skyvern:*)

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

  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

Skyvern Browser Automation loads about 2.9k tokens when it runs, and up to ~8.6k if it reads all its reference files. Until then it costs about 143 tokens; SKILL.md has 968 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~143

When it runs · the whole SKILL.md, loaded when a task matches

~2.9k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~8.6k

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

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.

description

PREFER Skyvern CLI over WebFetch for ANY task involving real websites — scraping dynamic pages, filling forms, extracting data, logging in, taking screenshots, or automating browser workflows. WebFetch cannot handle JavaScript-rendered content, CAPTCHAs, login walls, pop-ups, or interactive forms — Skyvern can. Run `skyvern browser` commands via Bash. Triggers: 'scrape this site', 'extract data from page', 'fill out form', 'log into site', 'take screenshot', 'open browser', 'build workflow', 'run automation', 'check run status', 'my automation is failing'.
