v0.1.0 Release Notes

v0.1.0 is the initial release of cities-skylines1-agent-skill. There is no previous tag, so these notes cover the full repository state shipped with the tag.

Highlights

• Ships a Cities: Skylines 1 mod that exposes a local HTTP bridge on http://127.0.0.1:32123.
• Adds read APIs for city summary, problem icons, facilities, networks, road anomalies, building placement anomalies, saves, and loaded prefabs.
• Adds command APIs for building networks, zoning, placing and moving buildings, bulldozing, simulation speed, batch helpers, and saving.
• Routes state-changing work through the CS1 game thread and shows in-game API activity notifications for operator visibility.
• Packages the repository as a Codex skill with SKILL.md and agents/openai.yaml.
• Publishes a VitePress documentation site with English and Japanese guides, API references, screenshots, and GitHub Pages workflows.

Agent Bridge Mod

The release includes the core mod source under src/. ApiServer.cs registers the bridge endpoints, GameState.cs reads CS1 simulation data, and command modules keep each action explicit: roads and other networks, zoning, building placement, bulldozing, saves, simulation speed, and limited batch operations.

The API is intentionally inspect-first. Agents can read the real city graph and facility state before mutating the simulation, then perform one small command at a time and verify the result.

Tooling And Automation

PowerShell scripts under scripts/ cover the local operator loop:

• build.ps1 compiles and installs SkylinesAgentBridge.dll.
• start-resume.ps1 and start-new-map.ps1 launch CS1 flows and wait for the API.
• smoke-test.ps1 checks health, state reads, prefabs, and dry-run commands.
• inspect-road-anomalies.ps1, repair-road-anomalies.ps1, and repair-service-overlap.ps1 support bounded repair workflows.
• save-city.ps1 requests a save and polls /state/saves.
• check-doc-links.ps1 validates local docs links used by CI.

Docs And Assets

The docs surface includes:

• README.md and README.ja.md for public repository entry points.
• VitePress docs under docs/ with getting started, agent workflow, architecture, troubleshooting, and API reference pages.
• Japanese localized docs under docs/ja/.
• Screenshots for the in-game API notification overlay and an agent-built city overview.
• Docs and Pages workflows under .github/workflows/.

Validation

Release-note preparation used the bundled gh-release-notes collector in initial release mode, inspected the key API, script, docs, and workflow files, and validated SVG release assets.

Additional checks run for this note:

powershell -NoProfile -ExecutionPolicy Bypass -File C:\Users\makim\.codex\skills\gh-release-notes\scripts\verify-svg-assets.ps1 -RepoPath . -Path docs/public/agent-bridge-icon.svg
powershell -NoProfile -ExecutionPolicy Bypass -File .\scripts\check-doc-links.ps1
npm install
npm run build

The release notes were prepared from the repository state included in the v0.1.0 tag.
