Onboarding to a company this large used to be a slow and steady process: pairing, reading, and a thousand little "why is this here" questions over months. But this time was different. From day one, I had a bunch of agents (Notion AI, Slackbot, Claude with MCPs and infinite tokens) that assisted me in learning and shipping.

I was able to ship features spanning multiple codebases faster than I expected, because I could ask AI to find documentation, create visualizations to explain things, search Notion and Slack for previous conversations about the tradeoffs I was navigating, run many rounds of self-review, and compare similar implementations. A codebase this size is more sampled than read, and the agents turned out to be an ideal sampling tool. But it also came with a subtle feeling of unease about what parts of the…
