port-a-mod SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
port-a-mod from rehan-remade/universal-modder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Port an existing mod to a newer game version or another mod loader while keeping its behaviour, values and quirks. Typical cases are an old Forge 1.7.10 or 1.12 Minecraft mod moving to modern Fabric or NeoForge, a Skyrim LE plugin moving to SE/AE, or a tModLoader 1.3 mod moving to 1.4. It covers pinning one source version, a private decompiled reference, an adaptation matrix, extracting the mod's data with scripts instead of retyping it, porting unit by unit with tests that catch drift…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Port a mod faithfully When porting an existing mod, the original is the spec. A port rarely fails for lack of code. It fails by **drift**: - values recalled from memory or a wiki; - mechanics borrowed from a later rewrite of the same mod; - quiet "improvements"; - renderers that look roughly right; - checks that the original made on the client and the port forgot. The method below carried a Thaumcraft 4.2.3.5 port from Minecraft 1.7.10 Forge to 1.20.1 Fabric: - 859 original classes became about 77,000 lines of port code; - 323 GameTests cover it, and scripted real-client scenarios check what tests can't reach; - the work spanned many sessions and two agent accounts. The field note `knowledge/games/minecraft/porting-thaumcraft-4-1-7-10-forge-to-minecraft-1-20-1-fabric.md` has its gotchas. Minecraft-specific mappings are in `references/minecraft-1-7-10-forge-to-1-20-fabric.md`. Run the **mod-any-game** loop around this skill (intake, recon, lab, verify, publish, field note). This skill replaces its "vertical slice" step with a long series of slices, one per unit of the original. …

How to install
mdr add rehan-remade/universal-modder/port-a-mod@sha256:54307cdf04558998The line at the top of this page pins the label git:20261012.315fa17, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
