defaultSkillRoots function
The default skill roots for a host: <cwd>/.fah/skills +
<cwd>/.agents/skills (project) and, when a home directory exists,
~/.fah/skills + ~/.agents/skills (user). Web/sandbox hosts pass
their sandbox cwd and no home (the sandbox FS carries project skills).
Implementation
({List<String> projectRoots, List<String> userRoots}) defaultSkillRoots({
required String cwd,
String? homeDir,
}) {
return (
projectRoots: ['$cwd/.fah/skills', '$cwd/.agents/skills'],
userRoots: homeDir == null
? const <String>[]
: ['$homeDir/.fah/skills', '$homeDir/.agents/skills'],
);
}
