Three tool-restricted agents (scout/search/researcher) that cannot
spawn sub-agents, plus a research skill that prevents recursive
agent chains and caps web fetching.
The single ai-skills plugin becomes plugins/g4b_ai/ inside a
reliquary-named Claude marketplace. Root README/CLAUDE.md now
describe the marketplace; the plugin's own docs move alongside it.
This makes room for additional themed plugins and non-Claude
formats in parallel.
