 ## 0.5.4 — Unreleased
 
+### Changed
+- Docs: README now explicitly warns against `pnpx @steipete/oracle` (pnpx cache breaks sqlite bindings); use `npx -y @steipete/oracle` instead. Thanks Xuanwo for flagging this.

 ### Fixed
 - Browser uploads: detect ChatGPT’s composer attachment chip (not echoed in the last user turn) to avoid false “Attachment did not appear” failures. Thanks Mariano Belinky (@mbelinky) for the fix.
 - Browser interruption: if the user/agent sends SIGINT/SIGTERM/SIGQUIT while the assistant response is still pending, Oracle leaves Chrome running, writes runtime hints, and logs how to reattach with `oracle session <slug>` instead of killing the browser mid-run.
