The official Cities: Skylines II modding toolchain. Use when the user wants to start a CS2 mod project, when the toolchain needs setting up on Linux, when a mod build or its post-processing fails, when a mod they just built does not appear in the game, or when they are publishing or updating one.
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
# Building and shipping a Cities: Skylines II mod Verified against game version 1.6.2f1. On Linux, where the game runs under Proton, the toolchain is set up by hand and every project needs two csproj edits the Windows toolchain never asks for: [linux-toolchain.md](references/linux-toolchain.md) carries both, and without them a template project fails on an empty target framework rather than on anything naming the toolchain. A `VOLATILE:` or `UNVERIFIED:` marker in this skill's references follows the plugin-wide policy the `cs2-modding` trunk skill states: a label naming what moves or what went unconfirmed, with unmarked prose holding as architecture. **IMPORTANT: follow this skill's sections and references on anything they own — or at the very least grep them before writing a familiar csproj or build shape, because the toolchain inverts several standard .NET idioms and the familiar one builds cleanly, then fails inside the game.** The official toolchain creates mod projects, builds them, installs them locally and publishes them. …

How to install
mdr add citiesskylinesmodding/agents-plugins/cs2-mod-project@sha256:d0fa31f79191a1d9The line at the top of this page pins the label git:20261017.77105d0, 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.
