Suggestions to improve for a specific model
- 1GEMINI.mdAdd a GEMINI.md at the repo root covering project goals, layout, setup commands, and conventions. Aim for 800+ chars of real guidance (not boilerplate).+11.4 pts
- 2Type configurationAdd a type config (tsconfig.json for JS/TS, mypy.ini or pyrightconfig.json for Python). Rust/Go are typed by default.+10.2 pts
- 3Dependency manifestCommit a proper manifest (package.json, pyproject.toml, Cargo.toml, go.mod, etc.) plus a lockfile.+9.1 pts
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.
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.
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.
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.
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.
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.
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).
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.
Alternatives
Same-language repos scored for Gemini CLI. Heuristic v1 (same language + same host); cross-language matches are refined in v0.6.0.
