What it does

  1. Multi-AgentOne skill, every agent

    Claude Code, Codex, Gemini CLI, Copilot CLI, OpenCode, Antigravity, Cursor, Kiro, CodeBuddy, OpenClaw, Trae, Qoder, QClaw, and WorkBuddy. Install a skill once; SkillDeck creates the right symlinks for each agent directory automatically.

  2. Registry BrowserDiscover community skills

    Browse the skills.sh leaderboard directly inside the app. Filter by All Time, Trending, or Hot. One click to install any listed skill — no terminal required.

  3. One-Click InstallGit clone to symlink

    Paste a GitHub URL or pick from the registry. SkillDeck clones the repo, parses SKILL.md frontmatter, creates canonical storage in ~/.agents/skills/, symlinks to each agent, and updates the lock file — all in a single operation.

  4. Update CheckerRemote diff at a glance

    Compares local commit hashes against the remote HEAD. A badge appears when updates are available; pull the latest changes with one click. No manual git fetch needed.

  5. SKILL.md EditorForm + markdown split

    A split-pane editor: structured form fields for YAML frontmatter on the left, live markdown preview on the right. Edit name, description, version, and agent compatibility without touching raw YAML.

  6. Auto-RefreshFilesystem watching

    Uses DispatchSource and FSEvents to monitor skill directories in real time. If you edit a SKILL.md from the terminal or another tool, SkillDeck picks up the change within half a second.

  7. skilldeck SkillNatural language management

    A built-in skill that lets any AI agent manage skills via natural language. Say "install the code-review skill" and the agent clones the repo, creates symlinks for all detected agents, and updates the lock file — following the same filesystem conventions as the GUI. Supports install, update, delete, and agent assignment. See skills/skilldeck/SKILL.md.

Supported agents

Every agent gets its own symlink farm. SkillDeck detects installed agents via CLI binaries and config directories, then manages the wiring.

03 · Questions

FAQ

What is a skill?
A directory containing a SKILL.md file with YAML frontmatter (name, description, version, agent compatibility) and a markdown body. Agents read these files to gain new capabilities. Think of it as a portable prompt package.
Where are skills stored?
Canonical files live in ~/.agents/skills/<name>/SKILL.md. Each agent gets a symlink to its own directory — for example, ~/.claude/skills/<name> points to the canonical path. The lock file at ~/.agents/.skill-lock.json tracks metadata.
Do I need all 14 agents installed?
No. SkillDeck detects which agents are installed by checking for CLI binaries and config directories. Only detected agents appear in the sidebar. You can still manage skills for agents you haven't installed yet.
Can I use this with skills I already have?
Yes. SkillDeck reads existing SKILL.md files and respects your current directory structure. It won't overwrite anything without confirmation, and it deduplicates skills that share the same canonical path via symlinks.
What macOS version do I need?
macOS 14 (Sonoma) or later. The app is built with SwiftUI and the @Observable framework, which requires macOS 14+. It's a native Apple Silicon binary.
