CS1 Agent Skill

Cities: Skylines 1 Agent SkillAPI-driven city operations for Codex agents

Inspect, repair, build, zone, simulate, and save a Cities: Skylines 1 city through a local bridge instead of screen scraping.

Start the Guide

State First

Read problems, facilities, road anomalies, networks, saves, and prefabs directly from CS1 data.

Small Commands

Use explicit build, bulldoze, place, move, zone, speed, batch, and save operations that are easy to audit.

Agent Ready

The root SKILL.md teaches Codex how to resume a city, inspect it, make scoped repairs, and verify the save.

What This Repository Contains
