HallOfFame

How the game's UI engine (Coherent Gameface / Cohtml) differs from a real browser, and the workarounds this codebase already uses. Use when writing or debugging the HTML/CSS/JS UI under HallOfFame/UI/src, when a CSS property, HTML element, or Web API behaves unexpectedly in-game, or when the user mentions cohtml, gameface, or coherent.

Write and run the mod's C# unit tests off-engine (net48 + xUnit). Use when writing or running C# tests, when a test hits an engine-bound type (Unity native call, Colossal.Logging.ILog, HttpQueries) or throws TypeLoadException off-engine, or when deciding where to put logic so it stays testable (plain Services/, not ECS Systems/).

Behavioral guidelines to reduce common LLM coding mistakes. Use when writing, reviewing, or refactoring code to avoid overcomplication, make surgical changes, surface assumptions, and define verifiable success criteria.

Provides expert guidance on mise (mise-en-place) — a polyglot dev tool and environment orchestrator that manages runtimes, environment variables, and project tasks. This skill should be used when users ask about mise configuration (mise.toml), installing or switching tool versions (Node, Python, Go, .NET, etc.), the mise task runner, environment variable management, secrets with SOPS/fnox, backends (ubi, cargo, npm, aqua), Lua plugins, shell hooks, migrating from asdf/nvm/direnv, or debugging with mise doctor.

Write and run the mod's UI tests with bun (pure-logic tests and React component tests). Use when writing or running UI tests, when a component test must render against the real game bundle / cs2/* modules, when configuring value bindings or asserting outbound triggers in a test, or when the game bundle fails to load / react injection anchors drift after a game update.
