Migrate direct ~/.codex/skills/gstack installs into ~/.gstack/repos/gstack during setup.\n\nCreate a minimal Codex runtime root that only exposes runtime assets and generated SKILL.md files so Codex no longer discovers duplicate source skills recursively.
Generated Codex skills (review, ship, plan-ceo-review, plan-eng-review) reference checklist.md, design-checklist.md, greptile-triage.md, and TODOS-format.md under .agents/skills/gstack/review/. Symlink these individual files instead of the whole review/ dir (which contains SKILL.md and would re-introduce duplicate discovery). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

This would be useful! I have ended up with duplicate skills in codex by running: git clone https://github.com/garrytan/gstack.git ~/.codex/skills/gstack
cd ~/.codex/skills/gstack && ./setup --host codex |

Adds migrate_direct_codex_install() to move old direct installs from ~/.codex/skills/gstack to ~/.gstack/repos/gstack. Adds create_codex_runtime_root() to expose only runtime assets (bin/, browse/, review files) via symlinks instead of symlinking the entire repo.

Summary
Fix duplicate Codex skill discovery when gstack is installed directly into
~/.codex/skills/gstack.This changes the Codex setup flow so we no longer expose the full repo under the Codex skills root, which was letting Codex recursively discover both:
That produced duplicate entries in the skill picker because both copies shared the same
name:frontmatter.What changed
~/.codex/skills/gstackto~/.gstack/repos/gstackduring./setup --host codex~/.codex/skills/gstackruntime root instead of symlinking the whole repoSKILL.mdbin/browse/binbrowse/distgstack-upgrade/SKILL.mdreview/checklist.md,review/design-checklist.md,review/greptile-triage.md,review/TODOS-format.md(individual files, not the wholereview/dir which contains its ownSKILL.md)~/.codex/skillsWhy this fixes the issue
Codex scans
~/.codex/skillsrecursively. Before this change, a direct install left the full gstack repo under~/.codex/skills/gstack, so Codex could discover both the source SKILLs and the generatedgstack-*Codex skills.After this change:
~/.codex/skills~/.codex/skills/gstackis now only a runtime sidecar, not a second discoverable skill treereview/dir) to avoid re-introducing duplicate discovery viareview/SKILL.mdThat removes the duplicate discovery path without changing the absolute paths referenced by generated Codex skills.
