Module add 

add <module>: a module of the game’s engine turned on (ADR-0009 §6). It:

1. turns on the module’s feature of the shuyi crate in the game’s Cargo.toml, keeping its layout (catalog::turn_on);
2. copies the module’s skill into the game’s skills (.claude/skills), if the game keeps them (catalog::copy_skill);
3. gives the first paragraph of the module’s README: what it is for;
4. says so when the game already has one of its alternatives on, with the README’s section on using both (BESIDE);
5. gives the line to add when the game’s code never installs the modules it turns on (shuyi::enabled_modules), and the line for the game’s formats() when the module adds formats.

Run twice, the second run changes nothing and says so (changed: false). A name that is no module of the engine fails with codes::UNKNOWN_MODULE and the names there are.
