“It creates the task before it does the work, so it now files its own tickets, which is more process rigour than most teams manage.”

Which one would each critic pick
| Critic | SourceCraft Code Assistant | Terragon | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.3 | 3.3 | SourceCraft Code Assistant — Pick this only if you already build and deploy on this vendor's cloud; pick GitLab Duo if you want the same one-platform story somewhere your team can actually buy it. |
| El Crítico | 4.8 | 3.3 | SourceCraft Code Assistant — The advertised flow ends with the agent triggering a deployment, and nothing published describes a human gate between the generated change and production. |
| El Profesor | 4.5 | 5.0 | Terragon — The design routed all agent output through pull requests, so verification borrowed the organisation's existing review process rather than inventing one. |
| La Inversora | 5.8 | 3.0 | SourceCraft Code Assistant — Tariffs are published on the platform in the vendor's own currency, which tells you the buyer this was built for, and it is a regional one. |
| La Jefa | 3.8 | 2.8 | SourceCraft Code Assistant — There is no dollar list price to multiply by sixty, the code lives on the vendor's cloud, and the data residency answer is a jurisdiction rather than a policy. |
| El Hacker | 2.8 | 5.0 | Terragon — Apache-2.0 on the way out, `terry` for local handoff and an MCP server in the box, which is a better goodbye than most companies manage. |
