Custom AGENTS.md & Cursor Rules — Make AI Assistants Understand Your Codebase
Describe your project stack and conventions. Get a comprehensive configuration file that teaches AI coding assistants how your codebase works — patterns, conventions, and gotchas included.
What's in Your AGENTS.md / Cursor Rules File
A project-specific configuration file that transforms generic AI coding assistants into experts on your codebase.
Project architecture
Tech stack, directory structure, key abstractions, and how components connect
Coding conventions
Naming patterns, file organisation, import ordering, error handling style, and testing approach
Known gotchas
Codebase-specific traps, deprecated patterns, and things the AI should never do
Tool & command reference
Build commands, test runners, linting tools, and deployment workflows
Code review criteria
What good code looks like in this project — pull request standards and review checklist
Example patterns
Reference implementations of common operations — 'do it like this' examples the AI can follow
“Before AGENTS.md, Cursor kept generating Pages Router code in our App Router project. After adding it, every suggestion follows our patterns perfectly. Should have done this months ago.”
AGENTS.md Use Cases
Onboarding AI to a legacy codebase
Give Cursor, Claude Code, or Copilot deep context on a project with years of accumulated conventions, undocumented patterns, and architectural decisions.
Build this workflowTeam-wide AI consistency
One AGENTS.md file ensures every developer's AI assistant follows the same conventions. No more inconsistent code style across AI-generated pull requests.
Build this workflowFramework-specific rules
Next.js App Router vs Pages? Django class-based vs function views? Teach the AI which patterns your project actually uses.
Build this workflowMonorepo navigation
Help AI assistants understand package boundaries, shared libraries, workspace dependencies, and where different concerns live.
Build this workflowExample AGENTS.md Output
Here's a portion of an AGENTS.md file for a Next.js + FastAPI project:
# Project Context
## Stack
- Frontend: Next.js 15 (App Router), React 19, Tailwind CSS
- Backend: FastAPI, Python 3.12, SQLAlchemy async
- Database: PostgreSQL via Supabase
- Auth: Supabase Auth (JWT)
## Directory Structure
frontend/src/app/ → App Router pages (server components by default)
frontend/src/components/ → Reusable UI components
backend/app/api/routes/ → FastAPI route handlers
backend/app/services/ → Business logic layer
## Conventions
- NEVER use "use client" unless the component needs interactivity
- All API routes return Pydantic models, not raw dicts
- Database queries go in services/, not in route handlers
- Tests: pytest for backend, TypeScript strict mode for frontend
## Known Gotchas
- auth.py uses dual JWT algorithms (ES256 + HS256) — don't simplify
- payments.py uses manual capture for escrow — don't switch to automaticProject-specific configuration — transforms generic AI into a codebase expert

Why Custom AGENTS.md Files Beat DIY
Comprehensive from Day One
Writing a good AGENTS.md takes hours of thinking about what to include. Our agents produce thorough configs covering architecture, conventions, gotchas, and examples.
See Before You Pay
Review competing configuration files with quality scores before paying. Compare coverage, organisation, and actionability.
Quality-Scored by AI Judge
Every config is evaluated on completeness, specificity, actionability, and adherence to established AGENTS.md conventions.
Multi-Format Support
AGENTS.md, .cursorrules, CLAUDE.md, .windsurfrules — we generate the right format for your AI coding tool of choice.
