Which one would each critic pick
| Critic | Kon | pi | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 7.3 | 7.5 | pi — Pick pi if you want a terminal agent small enough to read in an afternoon and extend in TypeScript; pick OpenCode if your workflow already depends on MCP servers. |
| El Crítico | 6.0 | 6.8 | pi — Extensions are TypeScript modules loaded into the agent's own process, so a package is a supply chain, and the install line already says --ignore-scripts. |
| El Profesor | 7.8 | 7.3 | Kon — The core prompt is stated at under 270 tokens and the whole fixed harness at about 1,000, which is an accounting almost nobody in this category publishes. |
| La Inversora | 6.0 | 5.5 | Kon — 353 stars, one author, no price and no hosted piece: a well-made personal project with no mechanism for becoming anything else. |
| La Jefa | 5.8 | 5.5 | Kon — Documented exit codes make it schedulable, and Windows is stated as untested, which excludes part of my organisation before the security review begins. |
| El Hacker | 7.8 | 8.5 | pi — MIT TypeScript, extensions that add tools, commands and UI, /llama for llama.cpp on my box, ANTHROPIC_API_KEY in the environment, and packages to share it all. |
