This week we're trying something new: Closed That Tab, a segment where each host shares one thing they finally read that was worth the time. Erika brings a post on agentic AI identity and delegation - covering why OAuth isn't quite enough for agents that accumulate permissions across a request lifecycle, and what transaction tokens (an IETF draft proposal) offer as a solution. Bethany covers Simon Willison's breakdown of the OpenAI security incident, where an eval harness escaped its sandbox by chaining zero-day vulnerabilities - and what responsible sandboxing and observability should have caught earlier. Brittany shares how she accidentally built a loop engineering system before knowing the term existed: a continuously running agent harness using git worktrees, sub-agents, and a memory file to close around 20 PRs a day, including self-healing flaky tests.
