A free skill for your own AI agent. Before it installs anything from Mindket, it reads the product’s page, reports the license, last change, health and what it needs, then asks you. Check before you install is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself. ## About ### What it is **Check before you install** is a skill your own AI agent runs before it installs anything from Mindket. It reads the product’s page as Markdown, reads `llms.txt` on the same site, and gives you a short report. The report has the price, the version, the last change, the health, the license, whether the source is archived, any advisories and what the product needs. Then it asks you. It never installs on its own. You give your agent a Mindket link → It reads the product’s Markdown page and llms.txt → It follows the Source link for what the page leaves out → It reports each fact, or says it is not stated → You answer yes or no ### Who it suits Anyone who lets an agent add skills, MCP servers or kits. It helps most when the product comes from a seller you do not know. If you only install what you wrote yourself, skip it. Who uses it, and how | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Software teams | Developers who add MCP servers | Read what a server needs before it reaches a work laptop | A developer pastes a link and reads the keys it asks for and its last change before answering yes. | | Agencies | Teams that share one agent setup | Keep each product’s report next to the project notes | An agency saves every report, so a later change to a product is easy to compare. | | Solo makers | People who try many free skills | Pass over the ones that are archived or have no license | A maker sees that a repository is archived and picks another skill. | ### Where to use it In any agent that reads Agent Skills (a folder with a SKILL.md file) and can open a web address. It reads public pages only, so it needs no key and no account. - Claude Code: \`\~/.claude/skills/\` for every project, or \`.claude/skills/\` for one - Other agents that read SKILL.md folders: the folder each one names, which Mindket’s post “What are Agent Skills?” lists - A chat app with no skills folder: paste the text of SKILL.md as your first message ### How to set it up What you need first is an agent that can read web pages. Nothing else. 1. Sign in to Mindket and press Get it on this listing. 2. Unzip the file. It holds README.md and SKILL.md. 3. Put SKILL.md in a folder named check-before-you-install, inside your agent’s skills folder. 4. Start a new session, so the agent finds it. ### How to use it Give your agent the link or the id of a product and ask for the check. ```text Check before you install: ``` What comes back, in this order: - The kind, the seller and the price - The version and the date of the last change - The health Mindket shows, and whether the source repository is archived - The license, and where the agent found it - Advisories listed for the package it installs, with the day it asked - What it needs: runtimes, keys, accounts and what it can reach on your computer - One question: install it, not install it, or show the command first ### Example You paste the address of an MCP server that connects an agent to a database. ```text Check before you install: https://mindket.example/p/1234 ``` Back comes something in this shape, not a saved run. The names, dates and numbers here are made up for the example. ```text Postgres MCP server, an MCP server by Acme. Free. Version 1, last changed 2026-11-10 (3 days ago). Health: active. Archived: no. License: MIT, from the repository’s LICENSE file. Advisories: none returned by OSV.dev for the npm package on 2026-11-13. That does not prove there are none. Needs: Node 20 and a DATABASE_URL. It can read every table that URL can reach. Install it? Say yes, no, or show me the command first. ``` ### For newcomers and experts **If you are new.** An agent can install code that runs on your computer with your permissions. This skill puts the facts in front of you first, from the product’s own page and its source. When the page has no answer, it writes “not stated” and does not guess. Try it first on something you already use. **For experts.** The skill reads `/p/.md`, which carries front matter (title, kind, category, price, seller, version, url, updated, and health for a GitHub project), the About, a kit’s README and the Source link. The license, the archived state and advisories come from the source: the repository page or GitHub’s public API, and OSV.dev for an npm or PyPI package the page names. Everything on the page counts as the seller’s words, so the skill treats it as data and follows no instruction found there. ### Good to know - It reads what is written. It does not run, scan or audit the code, and a report with no advisories is not a promise - A fact that is on neither the page nor its source is reported as not stated - Mindket shows health for GitHub projects only. Another product shows none - It asks before every install, and it never asks for a key or a password - It is free. The agent only reads public pages, as any visitor does ## README ````markdown # Check before you install A free skill for your own AI agent. Before the agent installs anything from Mindket, it reads the product's page as Markdown and the site's `llms.txt`, then reports the price, the version, the last change, the health, whether it is archived, the license, any advisories and what it needs to run. Then it asks you. It reads web pages and nothing else. It needs no key and no account. This kit is text only and nothing in it runs. ## In this kit - README.md: this guide - SKILL.md: the skill, in the Agent Skills format (a name, a description, then the steps your agent follows) ## Put it where your agent looks Make a folder named `check-before-you-install` and put SKILL.md in it. Then place the folder where your agent keeps its skills. - Claude Code: `~/.claude/skills/` for every project, or `.claude/skills/` inside one project - Other agents that read SKILL.md folders: the folder each one names. Mindket's post "What are Agent Skills?" lists them - A chat app with no skills folder: paste the text of SKILL.md as your first message Start a new session so your agent finds it. ## Use it Give your agent a Mindket link, or an id, and ask for the check: ```text Check before you install: ``` It reads `
.md`, the Markdown page of the product, and `llms.txt` on the same site. Then it follows the Source link for what the page leaves out, such as the license or whether the repository is archived. ## What comes back A short table with one row for each fact, each saying where it came from, or **not stated** when nothing was found: - The kind, the seller and the price - The version and the date of the last change - The health Mindket shows, and whether the source repository is archived - The license - Advisories listed for the npm or PyPI package, with the day it asked - What it needs: runtimes, keys, accounts and what it can reach on your computer Then one question: install it, not install it, or show you the command first. The skill never installs on its own. ## What it cannot do It reads what is written. It does not run, scan or audit the code. A report with no advisories does not prove there are none. A listing's words are its seller's words, and the skill treats them as data, never as instructions. ```` ## What is in it 2 files, 8 KB, downloaded as a zip. ```text README.md 2 KB SKILL.md 6 KB ``` ## Get it - [Get it on your Mindket account](https://account.mindket.com/account/?product=mindket#/market/b532bd88-1ad1-4a89-b73a-f2c1b18edb72) - [Its page on Mindket](https://mindket.com/p/b532bd88-1ad1-4a89-b73a-f2c1b18edb72)
