# Show HN: PlugVet, hygiene grades for AI agent plugins with the evidence shown > Source: > Published: 2026-10-23 13:28:03+00:00 ### A directory Claude Code skills, Cursor plugins, Codex plugins and MCP servers, in one place. The directory lists every entry the scanner has graded and published. Independent directory PlugVet is an independent directory of AI agent skills and plugins. Every entry is meant to show a public grade, the checks behind it, and the date we looked. For people who build with coding agents, ship vibe coded apps, or spend the weekend making a game. Got a GitHub link? [Look up a grade in seconds](https://plugvet.com/lookup/). **Scanner coming soon** Paste any GitHub repo and we'll grade it. 11,739entries graded A, B, C and D grades are published automatically. F grades are held and not listed. Updated each time the site is rebuilt. 1,000 entries were graded on , the latest date graded in the directory. These 12 are a sample from that day, in a fixed but arbitrary order. It is not a ranking, and it says nothing about quality. Five letters. Each one has its own shape and colour, so the grade does not depend on colour alone. We show what was checked and the date. Soon A basic check for common problems in a vibe coded app. The checker is not connected yet. You can read what it will look for. We read the source, run the same hygiene checks on every entry, and publish the letter with the evidence. Payment does not change a grade. Permissions, install and update steps, network, secrets, agent instructions, obfuscation, licence, and maintainer activity. Eight checks, every time. The letter is A, B, C, D or F. There is no E. The grade is what we found on that date. A later change can make it stale. Grades are a hygiene check, not a security guarantee. Magenta is the logo. It is not a grade. Spark yellow is a small accent. It is not a grade either. This grade is a hygiene screen, not proof of safety. Featured listing £39 a month. Category card £149 a month. Homepage sponsor £499 a month. Newsletter issue £99. Items graded D or F cannot take a paid slot. 1,974 A, 6,378 B, 2,481 C and 906 D. No F grades are published yet.
