Which one would each critic pick
| Critic | CodeArts Agent | Kiro | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.0 | 7.3 | Kiro — Pick Kiro if you want an agent that makes you write requirements and a design before it touches code, and accept that the bill is a credit meter you cannot route around with your own key. |
| El Crítico | 6.3 | 6.3 | no preference |
| El Profesor | 7.0 | 6.5 | CodeArts Agent — Retrieval is split between a cloud index over repositories of tens of millions of lines and a local language server supplying diagnostics, jumps and symbols. Two sources, two jobs. |
| La Inversora | 7.5 | 7.8 | Kiro — Kiro is AWS's entry, and the question is never whether AWS can fund it, only whether AWS keeps caring. |
| La Jefa | 7.5 | 7.0 | CodeArts Agent — Single sign-on, IP allow-lists, per-scope governance and token quotas, with a seat-based professional edition sized from 1 to 1000. This is the first row this quarter written for me. |
| El Hacker | 5.5 | 4.3 | CodeArts Agent — Closed source, and third-party models are mine to configure on the entry tiers but an administrator's decision on the professional one. It is an MCP server as well as a client. |
Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
