yolo-agpl-license-check - findings on the bundled example

Who it's for

ML and computer-vision engineers shipping closed-source YOLO detection in SaaS back ends, edge cameras or robots.

What breaks, and when

Ultralytics: "An Enterprise License is required if you want to use Ultralytics YOLO without open-sourcing your entire project" - a torch.hub.load call or base image pulls it in with no requirements line.

What it printed on the bundled example

== rf-detr Migration Check — 10 findings (5 errors, 5 warnings) in 3 files · 9 rules
  ERROR Dockerfile:2  [ultralytics-docker-image]
        The ultralytics/* base image ships the AGPL-3.0 ultralytics package in every container built from it, including containers deployed to cameras, robots and edge devices, which Ultralytics lists as needing an Enterprise License.
        fix: FROM python:3.12-slim  +  RUN pip install --no-cache-dir rfdetr
  ERROR Dockerfile:5  [ultralytics-package]
        This line installs the ultralytics package, which is AGPL-3.0. Ultralytics: "An Enterprise License is required if you want to use Ultralytics YOLO without open-sourcing your entire project", and that includes internal business tools, SaaS back ends and edge devices.
        fix: rfdetr  (Apache-2.0 for Nano, Small, Medium and Large)
  ERROR Dockerfile:6  [ultralytics-repo-source]
        This line pulls Ultralytics YOLO source straight from GitHub. The code carries the same AGPL-3.0 terms as the pip package, so a vendored copy needs an Enterprise License or a fully published project.

Install

Unzip into ~/.claude/skills/ (all projects) or your-repo/.claude/skills/ (one repo), then ask Claude Code: "We ship a closed-source camera service that uses YOLO. Where does this repo depend on Ultralytics, and what would we swap it for? Don't edit anything yet.". Needs Node 16+.

unzip yolo-agpl-license-check.zip -d ~/.claude/skills/

Ask Claude

“We ship a closed-source camera service that uses YOLO. Where does this repo depend on Ultralytics, and what would we swap it for? Don't edit anything yet.”

What it does not do

Not legal advice; it maps dependencies as text. No network calls, no edits without your OK.

FAQ

What is a Claude Code skill?

A folder with a SKILL.md and scripts that Claude Code loads when your request matches it. You ask in plain words and Claude runs the scanner the skill carries.

How is this different from asking Claude without the skill?

The skill carries a dated rule table and a scanner that reads every file, so Claude quotes the exact date and line instead of answering from memory.

Does it send my code anywhere?

Not legal advice; it maps dependencies as text. No network calls, no edits without your OK.

How do I install it?

What do I get when I buy?

The zip. On Whop it is in your library as a download lesson with the zip attached; on Gumroad it is the product file.
