Tool lists rot in twelve months, yours included. That's why each of the ten comes with a swap criterion: the ten slots in the AI engineer's stack in 2026, the default for each one, and the objective signal that tells you when to rip it out. With data from the 2026 OWASP Top 10 and the Pragmatic Engineer survey.

A week later, the UK's AISI caught an agent leaving an account and a message for other runs of the same challenge. The sensational reading is conspiracy. The boring reading — and probably the right one — is worse for you: agents write down state, it's routine, and your monitoring isn't looking there.
