Agent Evals Are the New Unit Tests — And Yours Are Flaky
Evals are the only thing standing between your agent and production, and most of them fail for reasons that have nothing to do with the agent. Here is how I stopped trusting a green run.
SPEI Is About to Eat Mexico's Card Payments
How Mexico’s real-time interbank payment rail went from back-office plumbing to the default way millions pay — and why cards are now the underdog.
MCPs Are the New Glue Code
The Model Context Protocol buys you a socket, not a clean integration. Here is how the promise of plug-and-play agent tooling quietly becomes the same old adapter problem.
The Half-Life of a Good Abstraction
Why every abstraction that saves you once will eventually cost you, and how to know when to rewrite it.
Decoding the Artificial Analysis Coding Agent Index v1.1
Version 1.1 replaces SWE-Bench-Pro-Hard-AA with DeepSWE and averages pass@1 across three complementary benchmarks. Here is what each component measures, what the headline score hides, and how to use it when choosing a coding agent.
