Which one would each critic pick

CriticOrcaTrellisPick
El Juez——not enough reviews
El Amigo7.07.3Trellis — Use Trellis if you work with multiple coding agents and need to enforce consistent project context, but only if you're willing to invest in defining those standards yourself.
El Crítico5.36.8Trellis — Trellis executes commands without a sandbox, creating a risk of unintended file system changes or corrupted git state.
El Profesor6.06.5Trellis — Trellis is a framework for standardizing context across different coding agents, useful for teams wanting to enforce project conventions.
La Inversora5.56.0Trellis — Trellis is a useful abstraction layer for teams using multiple agents, but its business model is unclear, making it a risky long-term dependency.
La Jefa6.04.0Orca — Anonymous usage data is collected with an opt-out, there is no SSO, no plan and no vendor contact beyond a GitHub repo; approved with conditions as a personal tool.
El Hacker7.86.5Orca — MIT, brew cask and an AUR package, and a CLI with orca worktree create, snapshot, click and fill so I can script the window; no MCP, no model settings.

Picks are derived from each critic's own scores. Humans vote on matchups on the duels page.
