AI coding tools like Claude Code, Cursor, Windsurf, and GitHub Copilot are only as good as the context they get. Here are 10 concrete steps to make your codebase work better with AI — and with human contributors too.
Your README is the first thing both humans and AI read. A good README covers: what the project does, how to set it up locally, the architecture at a high level, and how to run tests. AI tools use this as their primary context for understanding your project.
Quick win: Add a "Project Structure" section that maps directories to their purpose. This alone helps AI tools navigate your codebase 10x faster.
Modern AI tools look for project-specific instruction files:
These files give AI tools the project-specific context they need to generate correct, idiomatic code on the first try instead of generic suggestions.
TypeScript over plain JavaScript. Python type hints. Rust's type system. Go interfaces. Strong types act as documentation that AI tools can actually parse. They dramatically reduce hallucinated function signatures and incorrect parameter usage.
Quick win: If you're in a JavaScript project, adding a tsconfig.json with checkJs: true and JSDoc comments gives you type safety without a full TypeScript migration.
Tests serve two purposes for AI: they provide examples of how code should be used, and they give AI tools a way to verify that generated code actually works. A project with good tests lets AI iterate confidently — write code, run tests, fix failures.
Quick win: At minimum, document how to run your tests in the README or a CONTRIBUTING.md file. AI tools that can run npm test or pytest are dramatically more effective.
A CONTRIBUTING.md tells AI tools (and humans) how to add code to your project: branch naming, commit message format, PR templates, required checks. This prevents AI from submitting code that doesn't match your workflow.
GitHub Actions, CircleCI, or any CI pipeline signals to AI tools that there's an automated quality gate. AI tools like the ai-ready GitHub Action can automatically score your repo on every PR, tracking readiness over time.
A clear package.json, requirements.txt/pyproject.toml, Cargo.toml, or go.mod helps AI tools understand your dependency graph. Lock files (package-lock.json, poetry.lock) ensure reproducible environments.
Follow the conventions of your framework. Rails has its standard layout. Next.js has app/ and pages/. A predictable structure means AI tools can find what they need without guessing. Avoid deeply nested or unconventional directory trees.
ESLint, Prettier, Ruff, rustfmt, gofmt — automated formatters and linters enforce consistency. When AI reads consistently styled code, it generates consistently styled output. Include your config files (.eslintrc, ruff.toml, etc.) in the repo.
If your project exposes an API (REST, GraphQL, library), document it. OpenAPI specs, JSDoc/TSDoc, Python docstrings on public functions — these let AI tools understand your contract without reading every implementation detail.
The AI Ready score evaluates all 10 dimensions above on a 100-point scale:
Add the ai-ready GitHub Action to your CI pipeline. It scores your repo on every PR and posts the result as a comment, so you can track improvements over time. Available as a CLI tool too: npx ai-ready.
