How Cities: Skylines II is built and how a mod changes it. Use when writing or debugging CS2 mod code, when deciding how to change something the game simulates, when locating the systems, components or prefab data behind a game mechanic, when restarting the game after a build or running in-game tests, or when a mod runs at the wrong moment, breaks another mod, or does not survive a save.
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
# Modding Cities: Skylines II A mod is a .NET assembly the game loads by scanning it for a type implementing `Game.Modding.IMod`. What it does afterwards is add systems of its own, edit the game's data, or — rarely — rewrite a vanilla method at runtime. The simulation is Unity ECS: city state lives in components on entities, and systems running in fixed update phases are what change it. Most of what the player sees as content is a prefab — a data-driven object the game derives entities from — so changing what the game does is often changing data rather than code. A change therefore starts as two questions: which components carry the state, and which system writes them. Verified against game version 1.6.2f1. Every reference below states its own baseline. ## Five facts to hold before writing a line **IMPORTANT: follow this skill's references on anything they own — or at the very least grep them before acting on a familiar shape, because this game diverges from the standard shapes exactly where a prior feels safest, and the guess tends to compile, run and fail silently.** **Mods load late, through a two-method contract.** …

How to install
mdr add citiesskylinesmodding/agents-plugins/cs2-modding@sha256:0548059313cf179fThe line at the top of this page pins the label git:20261102.17b13a8, 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.
