The short answer
Choose Skiller to inspect installed skills, edit SKILL.md and manage coding-agent targets in a desktop app. Choose Vercel Labs’ Skills CLI for scriptable installation, command-line updates and remote environments. Both work with the skills.sh ecosystem.

| Read and edit skills | Inspect supporting files and edit SKILL.md in the app | Create a template with skills init; use your editor for revisions |
| Discovery | Marketplace sources include skills.sh and ClawHub | skills find and skills.sh discovery |
| Agent targets | Inspect targets and synchronize from the app | Explicit --agent targets; symlink or copy installation |
| Scope | Project-scoped and personal skill workflows | Project installation by default; --global for personal skills |

What changes in your daily workflow?
Skills CLI is a good match for the moment you know the repository you want. Run an installation command, select the skill and target agents, and continue in your terminal. Its documented commands also cover listing, removal, updates and creating a SKILL.md template. It can use a skill temporarily through skills use, without a permanent installation.
Skiller becomes useful when your next question is about the installed library: which agents have this skill, what are its instructions, and what should I change? Instead of moving between agent folders and a separate editor, you inspect the package and revise its instructions inside the desktop app. That is the main reason to choose Skiller over a terminal-only workflow.
Do Skiller and Skills CLI use the same ecosystem?
Skiller includes skills.sh in Marketplace, alongside ClawHub. Skills CLI is the installer for the open agent skills ecosystem, and skills.sh helps users discover packages. Choosing Skiller does not require abandoning repositories you found through skills.sh.
The tools also share the .agents/skills/ project convention for agents that support it. Skiller documents read-only access to the Skills CLI global lock file; that does not transfer ownership of CLI update history to Skiller. A shared path is compatibility, not a guarantee that two tools can independently overwrite the same package without conflict.
When is Skills CLI the better choice?
Use Skills CLI when the installation belongs in a setup script, a remote development machine or a repeatable terminal workflow. The README documents explicit agent and skill selection, global scope, copy mode and non-interactive confirmation flags. These make the intended install easier to express as a command.
For example, first list the skills in a reviewed repository, then install only the selected package for the intended agent. Avoid installing every package to every agent just because the command permits it. A repeatable command still needs a reviewed source and a clear destination.

npx skills add vercel-labs/agent-skills --skill web-design-guidelines --agent claude-code
When should you choose Skiller?
Choose Skiller when managing an existing collection takes more time than installing a new package. The visual library, inline editing and target controls put recurring tasks in one place. This is particularly useful when you alternate between Claude Code, Codex and Cursor and want to review the instructions each client receives.
Start with one installed skill. Open its instructions, make a small revision, select the intended targets and test the result in each client. Our cross-agent synchronization guide explains the checks that matter after deployment.
Can you use both tools?
Yes, for different parts of the workflow. Keep CLI installation and update history under Skills CLI, and use Skiller to inspect the local library where supported. Before editing or syncing a shared package, identify the authoritative source copy and preserve deliberate customizations. An upstream update can otherwise replace the instructions you just improved.
The practical choice is straightforward: Skills CLI for commands you need to repeat; Skiller for a collection you need to see, understand and edit. See the full skill-manager comparison if device backup or presets are also requirements.
FAQ
Is Skiller an alternative to skills.sh?
Skiller is a desktop manager; skills.sh is a discovery site. Skiller includes skills.sh as a Marketplace source. The direct terminal comparison is with Vercel Labs’ Skills CLI.
Can Skills CLI edit SKILL.md?
Skills CLI documents skills init for creating a template. Editing the instructions is normally done in a separate editor; Skiller provides editing within its desktop library.
Which should I use for automated installation?
Choose Skills CLI for explicit command-line installation and documented non-interactive flags. Choose Skiller for visual inspection, editing and everyday management of agent targets.
