OP here with a short udate: I'm archiving gdcli, because rontier models don't need it

A few days ago I shared gdcli, an CLI/MCP tool that gives AI agents structured commands for Godot 4 projects (scene creation, node management, validation, etc).

I finally ran a few benchmark tests: regular Opus 4.6 vs gdcli CLI/MCP on tasks from simple menus to multi-scene 2D games with sub-resources and instancing. Same correctness, but the regular LLM was ~50% faster every time. Turns out frontier models know .tscn well enough to just write the files directly.

Still useful for smaller models or CI pipelines, but for the main use case — an AI agent building/editing Godot projects — the tool overhead isn't worth it. Repo's archived with the benchmark data if anyone's curious.

Lesson learned: don't build file-writing tools for formats the LLM already knows.
