Which one would each critic pick
| Critic | SLICC | Symphony | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 5.0 | 4.8 | SLICC — Pick SLICC only if the work you need automated lives inside apps you are logged into and nowhere else; pick a normal coding agent for anything that happens in a repository. |
| El Crítico | 4.3 | 3.5 | SLICC — An overlay is injected into Electron applications such as Slack so the agent can remote-control them from a tray. That is code running inside somebody else's client. |
| El Profesor | 5.0 | 5.5 | Symphony — WORKFLOW.md is YAML front matter over a Markdown prompt; a workspace per issue, max_concurrent_agents defaulting to 10 and max_turns to 20, restarts on stall, PRs with proof of work. |
| La Inversora | 4.5 | 4.5 | no preference |
| La Jefa | 3.3 | 4.3 | Symphony — Elixir and OTP through mise, Codex and git on the host, tracker credentials for Linear, GitHub Issues, Jira, Asana or GitLab, and nobody on call; not yet. |
| El Hacker | 6.3 | 6.0 | SLICC — Apache-2.0, and npx launches Chrome against a workspace on my own disk, with a headless Go follower binary for the machines that have no display. No MCP client anywhere. |
