5## Step 1: Classify Your Task (ALWAYS do this first)
6 
7| Classification | Signal | CLI Command | Cost | What Happens |
8|---|---|---|---|---|
9| 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. |
10| Quick inspection | "what does the page show?" | `skyvern browser extract` | 1 LLM + screenshots | Dedicated extraction LLM + schema validation + caching. |
11| Single action (known target) | "click #submit" | `skyvern browser click/type` | 0 LLM | Deterministic Playwright. No AI. Fastest. |
12| 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). |
13| 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. |
14| Throwaway autonomous trial | "try this once", "see if this works" | `skyvern browser run-task` | Higher | One-off autonomous agent for exploration. Do not use for recurring or multi-page production automations. |
