Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Skillcheck for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "skillcheck": { "command": "npx", "args": [ "-y", "@reneturcios/skillcheck", "mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Skillcheck tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    node -v
    • A version number such as v26.13.1 = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed

    Open the Node.js download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

    Install once; it works for everything that needs Node.js

  2. Open the Claude desktop app’s settings file

Common questions

Is Skillcheck safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 13 days ago, and the latest version (0.1.0) reached the registry 15 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Docker on your computer.

What can I use instead?

skillcheck

Is this SKILL.md well-formed? skillcheck answers from the text itself: it parses the frontmatter block, checks the body, walks the markdown links, and compares the headings against the sections a skill is supposed to have — then reports every finding as a coded issue, plus the statistics it collected:

  • NO_FRONTMATTER — the document does not start with a --- line
  • UNCLOSED_FRONTMATTER — the frontmatter block never closes
  • MISSING_NAME / MISSING_DESCRIPTION — a required frontmatter field is absent
  • BAD_NAME_FORMAT — the name value is not a kebab-case slug (^[a-z0-9]+(-[a-z0-9]+)*$)
  • EMPTY_BODY — nothing but whitespace after the frontmatter
  • MISSING_FILE — a relative link target is not in the caller-supplied list of files that exist next to the skill
  • MISSING_SECTION — a required heading has no matching markdown heading (compared trimmed, case-insensitively, at any heading level)

Links to http://, https://, mailto:, and #anchor targets are counted but never checked. Relative targets have any #anchor suffix and surrounding <> stripped before the file check. Nothing is read from disk and nothing is fetched: the caller supplies the document text and the file list, so the same input always gives the same report.

CLI

npx @reneturcios/skillcheck validate --skill SKILL.md --files files.json --sections sections.json

npx @reneturcios/skillcheck --version

files.json and sections.json are each a JSON array of strings, and both flags are optional. Omitting --files skips the file check entirely (the report's stats.files_checked is then false).

Exit codes: 0 whenever the tool ran — a document that fails validation is a result, not a process failure — 1 on a runtime error, 2 on a usage error.

MCP server

npx -y @reneturcios/skillcheck mcp

MCP client config:

{

"mcpServers": { "skillcheck": { "command": "npx", "args": ["-y", "@reneturcios/skillcheck", "mcp"] } } }

Tools
  • validate_skill — Validate a SKILL.md document and report {valid, issues, stats}.
  • content (string, required) — the SKILL.md text
  • available_files (array of strings, optional) — relative paths that exist next to the skill; relative links are checked against it
  • required_sections (array of strings, optional) — heading texts that must appear as markdown headings

Docker

docker run -i ghcr.io/cloudcorprecords/skillcheck

docker run --rm -v "$PWD:/w" ghcr.io/cloudcorprecords/skillcheck validate --skill /w/SKILL.md
