The framework runs agents against actual Supabase environments using containerized stacks, scoring results with deterministic checks and LLM-as-a-judge. Key findings include: agents perform reasonably well without skills loaded, but skills help with edge cases and outdated knowledge; agents tend to avoid declarative schema workflows; newer Supabase libraries like @supabase/server are underused; skill activation is uneven across models; and Claude Code checks docs far less frequently than Codex-based agents. The benchmark results are publicly viewable and the regression suite runs daily internally. ## Full article daily.dev links to this article rather than hosting it.
