Commands:\n\
\x20 new <name> Create a new mod project in ./<name>/\n\
\x20 build Compile the current mod and package it as artifacts/<id>.yog\n\
\x20 build debug Same, but keep debug info in the native (for yog-debugger)\n\
\x20 check Generate .yog-build/ and `cargo check` the mod (host only)\n\
\x20 bench [filter] Run the mod's benches/*.rs #[yog_api::bench] functions (host only)\n\
\x20 designer-lib Build the mod's library for this machine (Yog-IDLE's designer); prints its path\n\
\x20 setup Check and install build dependencies (Rust, Zig, targets)\n\
\x20 doctor [--json] Report build dependencies without changing anything\n\
\x20 version Print the yog CLI version\n\
\x20 add <crate> Add a Rust dependency to yog.toml\n\
\x20 remove <crate> Remove a dependency from yog.toml\n\
\x20 schema <format> Print a format's schema as JSON (yblock, yitem, yrecipe, ydef, yres, yog.toml, ybook)\n\
\x20 run <config> Build, export, and launch a [run.<config>] dev instance\n\
\x20 run <config> --debug Same, built with debug info kept (see `build debug`)\n\
\x20 publish exports Publish this mod's exported API to crates.io\n\
\x20 ui gen [files] Generate .yog-build/generated/**/*.g.rs from .yui screens (build does this too)\n\
\x20 res check Validate resources/**/*.yres, regenerate accessors, list untranslated texts\n\
\x20 content check Validate content/**/*.yblock|*.yitem (blocks/items), regenerate yog-content.g.rs\n\
\x20 import resourcepack <zip|dir> [--model <id>|--all]\n\
\x20 Turn a resource pack's block/item models into content/ files\n\
\x20 import bbmodel <file.bbmodel> [--id <name>] [--item]\n\
\x20 Turn a Blockbench model (Java block/item) into a content/ file\n\
\x20 help Show this message\n\n\
Mod projects use yog.toml instead of Cargo.toml.\n\
Cross-compilation requires cargo-zigbuild + zig (yog setup installs them).\n\
Set YOG_TARGETS=linux-x86_64 (comma-separated tags/triples) to build only those platforms."
