Good morning, it's Tuesday, November 3rd, 2026.
Our lead story: security and trust drove the day, as teams closed an open file read, stopped default telemetry, and cleared vulnerable dependencies.
First, Headroom locked down what agents can touch. Pull request 4525 confines the optional workspace read tool to the workspace root, refusing anything outside with a single error, including parent directory tricks and escaping symlinks. That closes arbitrary reads of private keys and config files reported…
Second, dependency hygiene unblocked builds. Pull request 4614 moves the memory and graph packages past open advisories and fixes user scoping that was already broken on main, so search goes from always raising an error to working. Pull request 4599 clears audit failures in the glob pattern libraries by moving to…
Finally, a push to stop false failures. In Agent Reach, pull request 909 teaches health checks that an all not-found live test means the sample itself is gone, not the channel is broken. The same idea appears in the research skill, where pull request 1362 distinguishes a failed discovery step from a successful empty…
What's next: watch the November 15th audit exception expiry,…
