Nothing to hand? Load the — a goto_url first navigation, fixed sleeps, a raw AX-tree dump, unverified clicks, a typed password and a cloud daemon that never stops billing — or the , a plan-mode brief whose right design is a cloud browser, polite pacing and a stop-and-ask login posture.
Paste it — the prescan is free
No upload, no AI: the prescan reads your paste in the browser and lists what it mechanically found. For a script: the navigations, clicks, extractions, daemons and recordings, then the flags — goto_url as the first navigation, navigations without wait_for_load(), fixed sleeps, clicks never verified with a js()/page_info() check, the full AX tree printed raw, screenshot-only element finding, credential literals and typed passwords, cloud daemons started but never stopped or never named with BU_NAME, and recording slips. For a task: the signals that drive the design — interaction verbs, login walls, captcha risk, parallelism, scale. Each group explains why it matters. This part costs nothing and happens while you type.
The AI makes the calls — this is the metered part
A browser-automation engineer's pass: first the browser call itself — whether the job needs a browser at all (a plain fetch is faster, cheaper and more reliable when it works) and whether local Chrome or a managed cloud browser fits the task's parallelism, blocking risk and session needs. Then a readiness posture with the single most important change named, the inventory, prioritized findings across correctness, resilience, efficiency, auth-and-secrets, billing hygiene and etiquette — each with the problem, the impact and corrected Python — and the complete runnable script. Every prescan flag is confirmed or explicitly set aside. Findings may only cite calls and blocks that actually appear in your paste. Pricing is honest: a worst-case amount is reserved before the run and only what the run actually uses is charged — the meter next to the button shows both.
Fix, export, re-check
The script in one copy or as a ready-to-run .sh download, every corrected fragment in one paste-ready block, a tickable action checklist, the findings table as CSV, and Markdown or JSON export of the whole report. Then start fixing: the prescan re-runs as you edit and the strip above the run button counts the flags you have cleared, the ones still open and any you have just introduced — in the browser, for free, before you pay for a second check. Flight checks are saved to your SkillSafe account when you are signed in, so they follow you to another machine; restore puts the input back in the form too.
