This repository is a curated collection of rules for the ananicy-cpp daemon, which automatically adjusts process nice/ionice/scheduling priorities on Linux. It is primarily a dataset of process name to type mappings, organized by category (audio-video, browsers, games, desktop environments, services, tools, etc.), with additional cgroup CPU quota definitions. The rules are manually curated by the community and cover thousands of applications, including Linux native and Wine/Proton games, with detailed per-game executable entries. The repository includes JSON schemas for validation, a linting script, a sorting script for game rules, and a Makefile for installation. It is actively maintained and serves as the default ruleset for the CachyOS Linux distribution's ananicy-cpp package. No ETL pipelines or analytical models are present; the primary data product is the ruleset itself.
