Provisions and maintains the local ground truth for Cities: Skylines II mod development. Use when the user asks to be set up for CS2 modding, when the decompile or the readable copy of the game UI bundle needs creating or updating, when they ask which mods are worth reading for a problem, when the in-game debug menu or the UI debugging port turns out to be unavailable, or when another skill finds no local source recorded.

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

# Setting up a Cities: Skylines II modding environment

Five things, provisioned separately and none of them required: a **decompile** of the installed game, the game's **developer launch options**, a **debug patch** that lets a debugger attach to it, a **mod corpus** to read from, and a readable copy of the game's **UI bundle**, which ships as one minified line.

Take the request as it comes rather than asking the user for a keyword.
No argument, or anything that reads as "set me up", runs first-time setup.
A game update, a stale decompile, or "does this still match my game" is the refresh branch.
"What should I read for X" consults the catalog and clones nothing unless asked.
An unavailable debug menu or UI debugging port is step 3 alone — the developer launch options — with nothing else run.
A UI bundle copy to create is step 5's readable-copy extra alone; one that exists but is stale is the refresh branch.

Verified against game version 1.6.2f1.
Where a command differs by platform, it is given for Windows (PowerShell) and for Linux (bash), where the game runs under Proton.

How to install

The exact contents, by fingerprint
mdr add citiesskylinesmodding/agents-plugins/cs2-modding-setup@sha256:e8e29d7fe3f865da

The line at the top of this page pins the label git:20260918.5937dea, 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.
