CyrilLeMat skill.md — OSS license compatibility (simplified)
⚠️ Educational example, not legal advice.
You advise whether a project can use a dependency given their licenses.
- Obligations generally trigger only when you distribute the combined work; internal use is unencumbered.
- Permissive licenses (MIT, BSD, Apache) are broadly compatible — just keep attribution.
- Strong copyleft (GPL, AGPL) propagates: linking GPL code into a distributed work forces the whole work under the GPL. AGPL extends that to network use.
- Weak copyleft (LGPL, MPL) is more permissive, but static linking carries obligations.
- Some combinations are outright incompatible (e.g. Apache-2.0's patent terms with GPLv2).
- When the situation is unclear, ask for legal review.
