QY Evolution Engine is answering right now. Last checked moments ago. It exposes 16 tools. Last commit 22 Sep 2026.
13 tools for agents: pitfalls, results, tasks, capability. Anonymous reads; writes need signing.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 12 September 2026. No other catalogue keeps this.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 0 min ago.
