What problem does it solve? Non-technical users can describe a web flow in plain language, but turning that description into a reliable, deterministic Playwright check that runs on a schedule without any AI at run time is hard. This Skill guides the full authoring session from intent file to packaged, deployable test. ## Core Features & Use Cases - Structured authoring workflow: Walks through PREFLIGHT, EXPLORE, ASSESS, AUTHOR, RUN, and COMPARE phases, validating the intent file and confirming stable Playwright locators before writing any test code. - Quality gate before packaging: Enforces a nine-item checklist including consecutive clean runs, an independent critic pass, perfdata emission, and a VERIFICATION.md report before the test can be packaged with cep_package. - Site knowledge accumulation: Reads and updates a site-level KNOWLEDGE.md so consent dialogs, login quirks, and reliable selectors are reused across sessions instead of rediscovered. - Use Case: An admin runs check_cep --authoring with an intent file describing a login-and-check-balance flow; the Skill explores the site, authors the test reusing sanctioned robustness helpers, proves it green across consecutive runs, and produces a deployable tar.gz package. ## Quick Start Start an authoring session with check_cep --authoring and ask the assistant to turn your intent file into a deployable Playwright check.
