Overall

Strengths

  • CI configuration
  • CONTRIBUTING guide
  • Dependency manifest
  • License file
  • Linter / formatter config

Gaps

  • AGENTS.md / CLAUDE.md
  • Reproducible dev env
  • Pre-commit / git hooks

Suggestions to improve for a specific model

  1. 1
    AGENTS.md / CLAUDE.md
    Add an AGENTS.md covering project goals, layout, setup commands, and conventions. Aim for 800+ chars of real guidance (not boilerplate).
    +13.2 pts
  2. 2
    Reproducible dev env
    Add a Makefile or devcontainer or Dockerfile so the agent can set up the project in one command.
    +11.8 pts
  3. 3
    Pre-commit / git hooks
    Set up pre-commit (.pre-commit-config.yaml), husky, or lefthook to run format+lint on every commit.
    +5.3 pts

Per-model scores

Claude Code
Weights AGENTS.md and tests heavily — Claude Code leans on an instructions file and a fast feedback loop.
67.0
Cursor
Weights type config and a detailed README highly — Cursor's inline edits benefit from static types and skim-readable docs.
76.1
Devin
Weights CI and reproducible envs highly — Devin runs in a sandboxed VM and needs end-to-end automation.
71.1
GPT-5 Codex
Balanced profile as a reference point.
72.1
