Every self-improving agent hits the same trap. If it grades its own fixes, it learns to pass the test instead of getting better. The Kiro science team nearly shipped a fix whose entire gain came from one lucky run. Now in kiro-trace, the model proposes, deterministic code decides, and a human merges. The fixes that survived: → Redundant file re-reads down about 83% → Compaction retention up from 0.82 to 0.92 Full breakdown 👉 spr.ly/6010BHZrug

Re-explaining the same repo conventions? Again? Memory in Kiro IDE + CLI can carry forward your preferences, repo conventions, corrections, debugging insights, and approaches you've already ruled out, then bring them back when they matter. See and manage what Kiro remembers anytime. 👉spr.ly/6017BHnfPW

Is computer science still relevant?👀 @SwamiSivasubram tells @mndoci the fundamentals still matter. What students can build with them has changed. Kiro for students gives you a free year of kiro to build with. Get started → kiro.dev/students 📚Want Kiro at your university? Comment your school below!

Why does your coding agent's context fill up with stale copies of files that keep changing? Researchers on the kiro team built CORVUS to fix that: one live copy of each file, 9–50% fewer input tokens, same pass rates. Read the paper accepted to NeurIPS '26 👉 spr.ly/6018BHRvlu

With local sandboxing on, agent-run commands run with scoped access to files and the network. See how it works 👉 spr.ly/6010BHRv5o

Kimi K3 model from Moonshot AI is available in Kiro. It's the first open-weight model with 2.8T parameters, and room to hold your entire repo and spec in a single pass. Get started here: spr.ly/6016BHMzlj
