About this skill
Automates conversion of email HTML templates from six major ESPs to Mailtrap-compatible Handlebars syntax. Runs a bundled Python converter script for deterministic pattern replacements, then applies LLM judgment for complex edge cases. Handles single files, bulk directory conversion, or inline HTML pasted in chat. Generates a detailed report of changes made and flags any patterns that require app-layer code changes. Includes API field mapping reminders so the sending integration is updated alongside the template.
