What problem does it solve? This Skill handles the narrow case of running a legacy, explicitly authorized ChatGPT browser workflow: submitting a prompt to a ChatGPT project through a real Chrome session, confirming the requested model mode, downloading the generated artifact, and validating the file before reporting success. ## Core Features & Use Cases - Browser session control: Focuses the Oracle Chrome control tab and connects to the DevTools endpoint at 127.0.0.1:9222 via chrome-remote-interface. - Model verification: Inspects or selects Instant, Thinking, or Pro modes and saves JSON proof of the visible composer model state. - Artifact download and validation: Downloads the newest matching generated file, verifies SHA-256 hashes across copies, and validates ZIP, DOCX, PPTX, XLSX, PDF, HTML, JS, image, and GIF outputs. - Use Case: An owner approves a one-off task to generate an XLSX report through a specific ChatGPT project; the Skill submits the prompt file, confirms Pro mode, downloads the workbook, and validates xl/workbook.xml before returning the artifact path. ## Quick Start Ask the agent to run the approved ChatGPT browser artifact workflow with your prompt file and output directory, then verify the downloaded file with the validation script.
