What it does

Validates Claude Code plugin structure, JSON schemas, frontmatter format, security compliance, and marketplace catalog consistency. Runs the same checks as the CI pipeline to catch issues before committing.

When your AI uses it

Use when validating configurations or code

You don’t need to name it. Ask for the job in your own words — your AI loads the skill when the request matches.

What it can touch

  • Includes 1 script

    Your AI can run these when the skill is used — on your computer in a coding tool (which asks first unless you have told it not to), or in the AI’s own sandbox in Claude and ChatGPT.

    How we know

    Found in the skill’s folder: scripts/validate_plugin_marketplace.py.

  • Says which tools it uses

    It declares the tools it expects to be allowed: Read, Grep, Bash(cmd:*)

    How we know

    The allowed-tools field in the SKILL.md front matter.

  • No known risk pattern found

    Launch7’s automated check read all 11 text files in this skill and matched none of its risk patterns. This is not a guarantee: a check like this can miss new or disguised tricks, and the author can change the files after the check.

    How we know

    Read 2026-10-05, commit 680131e by pipeline/trust/analyze.py — 40+ patterns for hidden text, prompt injection, downloads that run, credential access and more. It reads; it never runs the skill.

  • Recently maintained

    Its repository has had changes recently.

    How we know

    Last push to jeremylongshore/claude-code-plugins-plus-skills: 2026-10-04 (1 days before the scan).

Read automatically from the skill’s own files on GitHub on 5 Oct 2026. Launch7 does not run or manually review skills: this lists what the check saw, and nothing here means “safe”. How we check

Add it to your AI

Partly. Upload it in Claude’s settings — the instructions work; the scripts need the full folder.

  1. Built in your browser from the SKILL.md on GitHub — nothing passes through Launch7.

  2. In Claude, open Customize → Skills, press +, then Create skill → Upload a skill, and choose the .zip.

  3. Make sure code execution is switched on (Settings → Capabilities). Skills need it.

  4. Start a new chat and ask for the job in your own words — Claude picks the skill up when it fits.

This skill ships 1 script beside its instructions. The download here is the SKILL.md alone — enough for the instructions, not for the parts that run code. Use the command route, or take the full folder from the repository.

How Claude does this: support.claude.com · checked 28 Sep 2026 · “Supported” means documented by the vendor; Launch7 has not run it end to end
