Skills: ready-made Vivu workflows for Claude.

What a skill is

A skill is a folder with a SKILL.md file in it. The file starts with a short header that names the skill and says when to use it, followed by instructions in plain Markdown. Claude reads the header of every skill you have installed and uses a skill when your request matches it. You can also ask for one by name. The folder follows Agent Skills, an open format that other agents read too; ChatGPT and Codex are among them. The steps on this page are written for Claude.

The skills here are written by Vivu. They call the Vivu connector for the video work: creating a project, opening its upload page, and searching. Some also use other tools you connect to Claude, such as Slack. Each skill's page lists what it needs, and shows its full text, so you can read exactly what Claude will be told before you install it.

Before you install

• Add the Vivu connector to Claude. Every skill here works through it. The fastest route is the Vivu listing in Claude's connector directory; the MCP server page has the other ways in.
• Check the skill's page. It says where the skill runs and what else it needs. A skill that downloads files, for example, needs a shell on your own computer.
• In the Claude app, keep code execution on. Skills need it. It is under Settings → Capabilities → Code execution and file creation, and it is on by default on Free, Pro and Max. On an Enterprise plan an Owner turns on Skills and code execution under Organization settings → Skills; on a Team plan Skills are on by default.

Install in the Claude app

Claude on the web and Claude Desktop

1. Download the skill. Keep it as a .zip; do not unzip it.
2. In Claude, open Customize in the left sidebar, then Skills.
3. Select +, then Create skill, then Upload a skill, and choose the .zip.
4. The skill appears in your skills list. Check that its toggle is on.

Safari on a Mac may unzip the download for you and leave a folder in Downloads instead of the .zip. If it does, right-click the folder and choose Compress to get the .zip back for this upload.

A skill you upload is private to your account. On a Team or Enterprise plan, an Owner can add it for everyone instead, under Organization settings → Skills, where members can still switch it off for themselves. The skills in your account also reach Cowork tasks, scheduled ones included, and the Code tab in Claude Desktop.

Install in Claude Code

CLI, IDE extensions, and the Code tab in Claude Desktop

Claude Code reads personal skills from ~/.claude/skills/, one folder per skill, in every project on that computer. Local sessions in the desktop app's Code tab read the same folder. Each zip here holds a single folder named after the skill, so unzipping it into ~/.claude/skills is the whole install. On macOS or Linux:

mkdir -p ~/.claude/skills
unzip ~/Downloads/youtube-competitor-watch.zip -d ~/.claude/skills

If Safari already unzipped the download, move the folder instead: mv ~/Downloads/youtube-competitor-watch ~/.claude/skills/.

On Windows, in PowerShell:

Expand-Archive "$HOME\Downloads\youtube-competitor-watch.zip" -DestinationPath "$HOME\.claude\skills"

That leaves ~/.claude/skills/youtube-competitor-watch/SKILL.md. Claude Code notices a new skill in a session that is already running. If ~/.claude/skills did not exist when the session started, restart Claude Code once so it starts watching the folder. Type /skills to see the skill in the list. To keep a skill to one project, unzip it into that project's .claude/skills/ folder instead, and commit it if your team should have it too.

This folder is for Claude Code only; Cowork uses the skills in your Claude account. Install a skill in one place: if Claude Code finds the same skill in both, the copy in ~/.claude/skills is the one that runs.

Use a skill

Ask for the task in your own words. Claude picks a skill when your request matches what the skill says it is for, and naming the skill in your request is the most reliable way to have Claude use it. In Claude Code you can also run it directly by its folder name, for example /youtube-competitor-watch.

A skill can stop to ask for inputs or approval along the way. Each skill's page says when it does, and what it will do on your behalf.

Update or remove a skill

Each skill's page and card show the date of its current version. To update, remove your copy and install the new .zip the same way. To stop using a skill, switch it off in Customize → Skills in the Claude app, or delete its folder from ~/.claude/skills in Claude Code.

Read a skill before you run it

A skill is a set of instructions that Claude follows with the tools you have connected, and Anthropic's advice is to install skills only from sources you trust. Before you install one of these, read its full text on its page; the .zip holds exactly that file, and the page gives the SHA-256 of the .zip so you can check your download. Look at what the skill will do for you, such as downloading files, posting to Slack or creating a scheduled task, and make sure that fits your organization's policies.

Troubleshooting

• Skills are greyed out in the Claude app. Code execution is off, either in your own settings or for your organization.
• The upload is rejected. The .zip must hold the skill folder at its top level, and the folder name must match the name inside SKILL.md. The files here are packed that way; if you re-zip one yourself, compress the folder, not the files inside it.
• There is no way to upload, or it fails, on a Team or Enterprise plan. An Owner may have turned off user-created skills. Ask them to add the skill for the organization under Organization settings → Skills.
• Claude does not use the skill. Check that it is switched on, then name the skill in your request.
• Claude says it has no Vivu tools. Add the Vivu connector and allow its tools in the conversation; the MCP server page has the steps.
• Claude Code does not list the skill. Check that the file is at ~/.claude/skills/<skill-name>/SKILL.md, not one folder deeper, and restart Claude Code if that skills folder is new.
