diagnose_crashread-only

Find the mod most likely behind a modded Minecraft crash (Fabric, NeoForge, Forge). Use it whenever the user shares a crash report or latest.log or says the game will not start. It is the only tool that reads logs, and it adds what the file does not hold: it checks every installed mod against the Modkeel lab (pairs in the pack that clashed, jars that crashed on that Minecraft version), says how ma

search_modsread-only

Turn a mod's display name or part of its id into the exact mod id the other lab tools take, and see which mods the Modkeel lab has data on. Use it first when you only have a name ("Entity Culling", "Sodium") or are unsure of the id; skip it when you already have the id. To download a mod, call find_mod_download with its name instead: it finds the mod itself. Matching ignores case, spaces and punct

get_mod_inforead-only

What one Minecraft mod is and where to get it: its Modrinth page (title, summary, categories, loaders, the Minecraft releases its author lists, client/server side, licence, downloads, source and issue links) next to a short Modkeel lab record (tested versions, run and pair counts). Use it for "what does this mod do?", "is it client-only?", "where do I download it?" or to link a suspect from diagno

find_mod_downloadread-only

The exact file to install for one mod on one Minecraft version and loader, with its download link. Use it for "where do I get X for 26.2 Fabric?", after diagnose_crash names a mod that needs another build, or when updating a pack to a new version. Checks, best first: the author's own build on Modrinth (status official: file, required mods, and lab runs of that exact file), a community port the Mod

get_mod_runsread-only

Everything the Modkeel lab saw one Minecraft mod do: each Minecraft version where it ran on a server or a client, or crashed, and every mod it ran with or clashed with. Use it for "does this mod work on 1.21.1?", "which versions was it tested on?" or to check a suspect from diagnose_crash. For one specific pair of mods, check_mod_pair gives a direct verdict; for what the mod is and where to get it

check_mod_pairread-only

Whether two Minecraft mods ran together in the Modkeel lab, clashed, or were never tested together. Use it for "can I use X with Y?" or to check two suspects from diagnose_crash; for one mod's whole record, use get_mod_runs. Takes two mod ids in any order (from names, call search_mods first). Unknown ids are not an error: the verdict is untested, meaning no lab run, never a known conflict. With mc

check_mod_listread-only

A whole mod list or modpack checked against the Modkeel lab at once: every pair in it that clashed, the mods whose jar crashed, the pairs that ran together, and the mods the lab has no data on. Use it for "will these mods work together?" or before updating a pack; for two mods, check_mod_pair is enough. Takes up to 300 mod ids (from names, search_mods first; unknown ids just land in untested_mods)
