Add global: prefix for agent_skills config entries that resolve to
~/.claude/skills/<name>/SKILL.md instead of the project root. This
allows injecting globally-installed skills (e.g., shadcn, supabase)
into GSD sub-agents without duplicating them into every project.
Example config:
"agent_skills": {
"gsd-executor": ["global:shadcn", "global:supabase-postgres"]
}
Security: skill names are validated against /^[a-zA-Z0-9_-]+$/ to
prevent path traversal. The ~/.claude/skills/ directory is a trusted
runtime-controlled location. Project-relative paths continue to use
validatePath() containment checks as before.
