Skyvern Browser Automation -- CLI Judgment Procedure

Skyvern uses AI to navigate and interact with websites. Every command below is a runnable skyvern <command> invocation.

When to Use This Skill

Use when you need AI-assisted browser automation for navigation, extraction, form filling, login flows, or reusable website workflows.
Use when deterministic selectors are unavailable and Skyvern's visual/a11y reasoning can identify page controls.
Use when a one-off browser task should become a repeatable workflow with run history and verification.

Classification	Signal	CLI Command	Cost	What Happens
Quick check (yes/no)	"is the user logged in?"	`skyvern browser validate`	1 LLM + screenshots	Lightweight validation (2 steps max), returns boolean. Cheapest AI option.
Quick inspection	"what does the page show?"	`skyvern browser extract`	1 LLM + screenshots	Dedicated extraction LLM + schema validation + caching.
Single action (known target)	"click #submit"	`skyvern browser click/type`	0 LLM	Deterministic Playwright. No AI. Fastest.
Single action (unknown target)	"click the submit button"	`skyvern browser act`	2-3 LLM, no screenshots	No screenshots in reasoning. Economy a11y tree. For visual targets, use hybrid mode (selector + intent).
Same-page multi-step	"fill the form and submit"	`skyvern browser act` or primitive chain	2-3 LLM or 0 LLM	Use `act` when labels are clear. Use click/type/select directly when you know selectors.
