**The Context Gap (Free)
Dear Reader,
Who’s watching your AI agents?
This past week alone: Codex shipped its Chrome extension, giving OpenAI’s agent access to your signed-in Gmail, LinkedIn, and Salesforce. Meta confirmed “Hatch”, a consumer agent built to do your Instagram shopping. Alibaba integrated Qwen with Taobao, launching agentic checkout across four billion products.
The tech press framing is breathless. The capability is real. The question nobody’s asking: who audits what the agent does once it’s in there?
The two-second test
A few weeks ago, a stranger tried to sell me an exercise bike I’ve never owned, on a Canadian classifieds site I’ve never used. The wrongness was obvious in two seconds. My AI agent didn’t see it — a few days later it queued up “ship the bike, print the prepaid label, today” as a task in my morning brief.
The agent wasn’t fooled. It processed the emails correctly by its own rules. The problem was that the rules couldn’t represent what I already knew.
The flash that fired in those two seconds was domain knowledge — a messy, lived-in pattern you build up by being wrong about things and learning from it. I never told my agent “I don’t live in Canada,” because I never had to tell myself.
Before you authorise the next agent inside your Gmail, your Instagram, or your Taobao cart, run the test: in this exact context, what would this agent do that I’d have caught in two seconds?
If you can’t answer that yet, the agent isn’t ready. That’s a question you can answer in an afternoon.
What’s in the full issue
The paid edition picks up from here. Michael Polanyi called this tacit knowledge in 1966 — “we can know more than we can tell.” The full issue walks through what that means for every agent you authorise: the Overhead Multiplier (where the time AI saves you gets refilled with risk faster than the savings compound), Cory Doctorow’s Reverse Centaur (humans in the loop functioning as accountability sinks), and the loop-sizing question that determines whether you actually catch a context gap when it appears.

Also in this week’s workbench: a freediver analogy for explaining context windows to non-technical audiences — with the verification story behind the diagram (Claude Opus 4.7 was first listed at 200K tokens; Gemini 3 Pro was inflated to 10M). And a new open-source MCP server I shipped this week for cyber threat intelligence disambiguation.
