Most important updates

AWS launches Kiro agentic IDE: generally available, replaces Amazon Q Developer, spec-driven development, free tier with 50/mo interactionsMar 2026

Current obstacles

Spec quality constraintsThe agentic loop is only as good as the initial spec. Poor or ambiguous specifications limit what the agent can accomplish.

How it works

4 parts

Spec-first

Specs are the source of truth

The spec is source of truth; code is artifact. Inverts traditional workflows where specs accompany code.

Agentic loop

Plans, writes, tests, iterates

Acts as collaborator: plans, writes files, runs tests, and iterates within user-set constraints.

Dual-model routing

Sonnet for reasoning, Nova for throughput

Routes reasoning-heavy tasks to Claude Sonnet 4.5, mechanical work to Nova via Bedrock.

VS Code base

Code OSS compatible

Inherits themes, shortcuts, extensions from Open VSX marketplace; no vendor lock-in.
