The limits every Sylin tool is built to respect. Where one isn't met yet, the page says so.
The tools run where you are - your laptop, your LAN, the rack in the closet. Nothing routes through a service we operate. If your internet drops, your tools don't.
Sylin's tools were built in partnership with AI coding agents, and they expose themselves to agents the same way they expose themselves to you. Model Context Protocol is a first-class surface, not a bolt-on.
A tool you rely on shouldn't be able to turn against you. Ours don't check in, don't expire, and don't degrade when a subscription lapses. Where there's a paid layer, it governs how the tools are used - it never gates your ability to run them. Ghostlight shows how โ
The engines are open. You can read them, run them, fork them, and keep them. Where there is a commercial layer - as in Ghostlight - it governs; it never gates the ability to run the thing.
What keeps the other four honest. Less a fifth commitment than a habit - one that shows up as things you can check:
Every project page has a "when not to use this." We publish nothing we can't keep true.
