AnasDevO/PackTemplateCompanion ? reverse-engineered prompt

Build me a Minecraft 1.12.2 companion mod that checks my modpack at runtime and tells me what’s outdated, risky, or replaced by better modern options.

I want it to scan the loaded mods, inspect configs for bad or crashy settings, and compare everything against a live set of master lists that can be updated from JSON so the recommendations stay current. It should also know about Universal Tweaks and point out mods or features that are already covered there, along with the config changes I’d need instead.

When the game starts, it should generate clean HTML and Markdown reports in the config folder, with clear notes, links to fixes or replacements, and a simple way to open the report in my browser after I join a world. If you need to check current docs or best practices online, go ahead. The goal is to make it easy for someone building or cleaning up a modpack to see what should be removed or changed without digging through everything manually.
