Suggestions to improve for a specific model

  1. 1
    CONTRIBUTING guide
    Add CONTRIBUTING.md describing branch naming, commit style, test commands, and the PR process.
    +5.3 pts
  2. 2
    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
  3. 3
    Reproducible dev env
    Add a Makefile or devcontainer or Dockerfile so the agent can set up the project in one command.

Per-model scores

Claude Code
Loads CLAUDE.md at the start of every conversation per Anthropic's memory docs, so AGENTS.md / CLAUDE.md and a fast test loop carry the most weight.
79.5
Cursor
Per Cursor's Rules docs, reads `.cursor/rules/*.mdc` and AGENTS.md as the canonical repo-side input. Type config and a clean README still aid the codebase index but aren't the docs-cited signal.
74.8
Devin
Operates from a sandboxed Ubuntu VM and runs an 8-step machine setup (deps, secrets, language versions, lint/test commands) per Cognition's repo-setup docs. CI config files alone aren't what the docs ask for — a runnable dev environment is.
76.8
GPT-5 Codex
Reads AGENTS.md before doing any work per OpenAI's Codex docs — the strictest AGENTS.md adherent of any agent here. Hierarchical (per-directory) AGENTS.md and AGENTS.override.md are first-class.
81.1
Gemini CLI
Reads hierarchical `GEMINI.md` (global → workspace → component-level) at every prompt per Gemini CLI's docs. The long-context advantage favors repos that split context per directory rather than docs-heavy in general.
72.2
Aider
Auto-lints on every edit by default; runs the configured test command after edits when `--test-cmd` is set (per Aider's lint/test docs). A green linter and a declared test command translate directly into successful commits.
73.2
OpenHands
Runs in a sandboxed container and executes `.openhands/setup.sh` at session start per OpenHands' repo-customization docs. Root AGENTS.md is now the preferred always-on instruction surface (microagents are deprecated in favor of it).
67.6
Pi
Minimal terminal coding harness. Loads `AGENTS.md` (or `CLAUDE.md`) at startup — global, parent dirs, then cwd — per the Pi coding-agent README. Sandboxing is deferred to user-installed extensions.
81.5
