On one docker-compose file it found Redis 7.4 (RSALv2 / SSPLv1), Elasticsearch 8.15 (SSPL + Elastic License 2.0), Bitnami PostgreSQL (moved to bitnamilegacy on 2025-08-28), Vault 1.17 (BUSL-1.1) and Grafana 11 (AGPLv3) — with the date each licence changed.

What you get
• 30 rules: HashiCorp BUSL releases, Redis, Elasticsearch, Kibana, MongoDB, CockroachDB, Grafana, MinIO, Sentry, n8n, Bitnami, and commercial packages next to MIT ones
• Ask Claude “do we use anything that is BUSL, SSPL or AGPL?” before shipping a closed-source or hosted product
• Reads package.json, requirements*.txt, go.mod, Dockerfiles, compose files, pom.xml, Helm charts
• Exits 1 on errors, so it can also fail a CI build

Install in 30 seconds
Unzip into ~/.claude/skills/ (all projects) or your-repo/.claude/skills/ (one repo), then ask Claude Code: “do we use anything that is BUSL, SSPL or AGPL?”. Needs Node 16+.

What it does not do
It works offline. It is a factual licence-change check, not legal advice.

FAQ
Q: How is this different from asking Claude without the skill?
A: The skill carries a dated rule table and a scanner that reads every file, so Claude quotes the exact date and line instead of guessing from memory.
Q: How do I get the files?
A: After paying, open it in your Whop library: in “Download — license-flip-audit” the lesson “license-flip-audit.zip” has the zip attached.
