About
Dimillian's macOS app for managing your OpenAI Codex skills — install, organize, enable/disable from a clean native UI.
What it does
It inventories skill bundles across Codex, Claude Code, OpenCode, and GitHub Copilot, reads their metadata and supporting content, and groups matching copies. It also searches Clawdhub, installs downloads to selected agents, imports folders or archives, deletes local bundles, and publishes owned skills.
Why it's ranked here
This is a focused, practical manager for people running several coding agents on one Mac. Cross-agent discovery, custom roots, remote installation, and publishing form a coherent workflow. Its value drops sharply outside macOS, and replacement-style remote installs deserve caution.
What's good
The scanner counts references, assets, scripts, and templates, then exposes those details as useful tags. It previews Markdown references, recognizes the same skill across multiple agents, supports custom search roots, and records Clawdhub origin metadata. Content hashing also lets publishing detect changes since the previous publish.
Tradeoffs
The documented requirement says macOS 26 or newer, while the package manifest targets macOS 15. Remote installation removes an existing destination before copying the downloaded bundle. Archive handling depends on the system ditto utility. Publishing requires Bun, invokes the latest Clawdhub package, and expects an authenticated account.
How to use it well
It suits Mac users who maintain overlapping skill collections for several coding agents and want one place to inspect, import, distribute, or publish them. Use version control or backups before replacing remote installations. It does not cover editing skill content, cross-platform management, or hosting a private catalogue.
Technical notes+
Package.swift defines a Swift 6.2 executable and CodexSkillManagerTests test target, targets macOS v15, enables complete strict concurrency, and depends on MarkdownUI plus Sparkle. Sources/CodexSkillManager/Workers/SkillFileWorker.swift scans directories, parses frontmatter with a Markdown fallback, hashes text files with SHA-256, extracts ZIP archives through /usr/bin/ditto, and replaces existing remote-install directories. Sources/CodexSkillManager/Workers/SkillImportWorker.swift validates folders or ZIPs and avoids import collisions with numeric suffixes. Sources/CodexSkillManager/Workers/ClawdhubCLIWorker.swift resolves bunx, checks Clawdhub identity, computes semantic version bumps, and publishes through clawdhub@latest. Sources/CodexSkillManager/Skills/Shared/SkillPlatform.swift defines Codex, Claude Code, OpenCode, and GitHub Copilot storage locations. Sources/CodexSkillManager/App/CodexSkillManagerApp.swift enables Sparkle only for configured, Developer ID-signed app bundles.
