- Kevin Liao — agents don't need memory, they need documentation
Kevin Liao argues that memory plugins for coding agents are just RAG over old chats, and that agents work better with a folder of plain Markdown docs they read before and update after each task. The essay reached 324 points on Hacker News.

- Simon Willison — usage-billed services need hard budget caps by default
Simon Willison argues that pay-per-use services should stop spending at a hard cap by default, with uncapped billing as an opt-in. Coding agents make it easy to spin up code that can run up a surprise bill.
