the cheapest model call is the one you deleteIf you need a pile of machinery to make a model behave, the model shouldn’t be there.agentsJun 21, 2026a prompt is a vote, not a checklistWhy a soft “…unless…” clause loses to the paragraph around it.agentsJun 15, 2026evals turn a demo into a productA golden set, an LLM judge, and trusting the delta — not the score.agentsJun 12, 2026deterministic state machines pay for themselvesMake the core pure and the features you haven’t thought of get easier.engineeringJun 11, 2026casual is the hardest registerThe impressive case is the messy, unwritten one — so build for it.agentsJun 10, 2026refusing an injection is also a leakFor a tool that transforms untrusted text, the safe-looking fix creates a second leak.agentsJun 9, 2026validate your environment at the edgeFail loud and early on bad config — but be precise about which edge.engineeringJun 8, 2026a library relocates the bugA battle-tested dependency doesn’t delete your bugs — it moves them to how you call it.engineeringMay 29, 2026
