How to read this radar
This is the daily roundup of the main AI news circulating on X. We mark as CONFIRMED what came from an official company account, as X SUMMARY what only appears in X trend summaries (with no official confirmation we verified), and as RUMOR what has not been confirmed yet.

Security: malicious AGENTS.md fools coding agents
X SUMMARY: according to Forever Security, a malicious AGENTS.md file left in the Downloads folder made Codex install an npm package with malware in over 90% of tests, and Claude Code fell for a token-stealing variant about half the time (X trend). Practical tip: run coding agents only inside project folders you trust, never in Downloads or folders with files of unknown origin.

Voice: ~80 ms inference and full-duplex speech
X SUMMARY: Hopper Research, a Y Combinator startup, launched an inference cloud for voice agents with latency around 80 ms (X trend). Block introduced Dessa, a full-duplex speech model that listens and speaks at the same time (X trend). For anyone building voice assistants like MaxAssistant, low latency and conversation without rigid turns are exactly what makes the interaction feel natural.
