PR #883 nested Claude skills 3 levels deep under gsd-ns-*/skills/<stem>/SKILL.md.
Claude Code's Skill tool scans only one level under ~/.claude/skills/ — nested
concrete skills were never listed and Skill(skill="gsd-plan-phase") calls failed.
Revert to flat layout: all ~61 concrete skills at ~/.claude/skills/gsd-<name>/SKILL.md.
The 6 other runtimes confirmed as non-recursive scanners (cline, qwen, hermes, augment,
trae, antigravity) retain their nested layout — only Claude changes.
Tradeoff: ~61 top-level skill dirs return to the flat install, but they are discoverable
and invokable. Nested concretes were invisible to the Skill tool entirely.
