# EOL/EOS Flagging ## Overview End-of-life and end-of-support are two related but distinct events. End-of-life (EOL) generally means the vendor has stopped selling or actively developing the product. End-of-support (EOS) — sometimes called end-of-extended-support — means the vendor stops shipping security patches. EOS is the harder deadline operationally: a device past EOS is accumulating unpatched vulnerabilities with no fix coming, regardless of whether it still "works." This skill flags both, keeps them distinct in the output, and prioritizes the resulting list by how much it actually matters if a given device is left running past its date. This needs two ingredients: **device inventory data** (make, model, OS version, firmware version — pulled live from whatever RMM is connected) and **EOL/EOS knowledge** (which dates apply to which OS/hardware — general knowledge, not something the RMM exposes). The two must be combined explicitly, and the knowledge half must always carry a verification caveat, because vendor lifecycle dates do change (extended support gets purchased, timelines shift) and this skill's knowledge has a cutoff. This is distinct from `warranty-tracking`: a device can be fully in warranty and past OS end-of-support (an aging laptop still under a 5-year warranty but running an OS version no longer patched), or out of warranty and still fully supported (an older desktop on a current, supported OS with no active vendor patching risk). Both signals feed `refr...
