The missing GUI for wrangling Codex skill files

What it does

Codex Skill Manager is a SwiftUI app that corrals your local AI assistant skills—those SKILL.md files that Codex and Claude Code keep in hidden directories under your home folder—into a single browsable window. It renders the Markdown, handles imports from folders or zip archives, and lets you pull new skills from Clawdhub without leaving the app. Think of it as a dedicated package manager, except the packages are text files that tell your AI how to behave.

The interesting bit

The app is built entirely with SwiftPM and ships without an Xcode project, which is a neat flex for a native Mac app. More practically, it speaks to both ecosystems at once: skills can be installed into Codex directories, Claude Code directories, or both, with visual tags tracking where each file lives and what version it carries.

Key highlights

• Browses local skills from ~/.codex/skills, ~/.codex/skills/public, and ~/.claude/skills in one sidebar
• Renders SKILL.md with Markdown and inline reference previews via swift-markdown-ui
• Imports skills from local folders or zip files, and deletes them from the sidebar
• Searches and downloads remote skills from Clawdhub into either or both toolchains
• Visual tags show installed status (Codex vs. Claude) and version numbers

Caveats

• Requires macOS 26+ and Swift 6.2+, which are aggressively bleeding-edge and will limit who can build or run it today

Verdict

Grab it if you live in Codex or Claude Code and want a GUI for skill housekeeping. Skip it if you are not on macOS, or if you prefer managing a handful of markdown files by hand.
