   <h1>🧠 SiriBench — On-Device iOS Agent Benchmarking</h1>
-  <p>How we <b>author tasks</b> for an on-device iOS agent — Apple's Foundation Model driving the
-  <b>real</b> Reminders, Calendar, Contacts & Messages — and <b>capture every run as a verifiable trajectory</b>.
-  Each task seeds a real iOS world, runs through a single Standard Agent with 11 tools, and is scored from the
-  trajectory <i>plus</i> a re-read of the real OS store.</p>
+  <p>This is a benchmark for evaluating <b>Apple's Foundation Model</b> — the on-device model that
+  powers <b>Siri</b>. We created a set of real-world tasks across the actual iOS apps
+  (Reminders, Calendar, Contacts & Messages), let the model complete them on its own, and check
+  whether it actually got them right.</p>
