Can it handle manual steps like 2FA or Captchas?

Yes, the workflow allows for defining manual checkpoints where the automation pauses and resumes after user intervention.

Which browser libraries are supported?

The skill is designed to work seamlessly with both Puppeteer and Playwright for building Node.js automation runners.

How does this skill reduce LLM costs?

It utilizes a single-shot LLM call only when necessary for element selection, relying on deterministic Node.js code for the execution phase to avoid continuous API usage.

What happens if the LLM fails to select an element?

The skill implements defensive JSON parsing and can fall back to heuristic ordering if the LLM response is invalid or fails.

Builds cost-efficient Node.js automation workflows that combine Puppeteer/Playwright with targeted LLM element selection.

This skill enables developers to transition from expensive, manual LLM-driven browser exploration to scalable, deterministic Node.js runners. By integrating Puppeteer or Playwright with single-shot LLM calls for element selection, it significantly reduces API costs while maintaining high reliability for complex web interactions. It is particularly effective for productizing page-structure discovery into automated flows that include heuristic filtering, robust error handling with screenshot captures, and playback controls for dynamic content.
