The root router listed every skill and ended 'When in doubt, invoke the
skill'. Current Claude models follow that literally: they tried to invoke
skills a user had turned off in Claude Code's skillOverrides (which gstack's
own disabled_skills render cannot see), and borderline requests tipped into
full workflows. The router now routes only to skills in the session's
available-skills list and names when to answer directly; the CLAUDE.md
routing block skill-start offers says the same.
