AGENTS.md: Formalizing Project Architecture with AI Agents

AI agents can transform existing code into a structured document that captures the architecture, logic, and relationships between components. This approach creates an intermediate layer between concept and implementation, useful for protecting intellectual property in development.

Traditionally, development control has relied on repositories, NDAs, and contracts. In conflicts where a team leaves and creates a similar product, proving architectural copying is difficult. AI eliminates this uncertainty by generating a comprehensive system description.

The AGENTS.md Standard and Its Application

AGENTS.md is a file that agents read before working with code. The reverse process: analyzing code to create a specification. In Cursor or similar IDEs, a single command outputs a Markdown document with:

  • Project architecture;
  • Component descriptions and relationships;
  • Data flows;
  • Key decisions;
  • APIs and dependencies.

This document allows recreating the project on a different tech stack. It captures a level missing from developers' minds or raw code.

Step-by-Step Specification Creation

  • Open the project in an AI IDE (Cursor, Claude Dev, etc.).
  • Enter the prompt:
Analyze the entire project and create a SPEC.md file. Include: project architecture, descriptions of key components and their relationships, main data flows, key technical decisions, API descriptions (if any), dependencies between modules. Use Markdown. Make it so this document can be used to recreate the project on a different technology stack.
  • Save SPEC.md.
  • Record the date and file hash (notary, Git timestamping, or blockchain services).

Advantages in Real-World Scenarios

Conflict with a departed team. A dated file proves architectural priority in negotiations or court. Code can be rewritten, but the specification is hard to refute.

Patent preparation. SPEC.md serves as ready technical documentation for a patent attorney, detailing the invention.

Internal documentation. Simplifies onboarding, refactoring, and stack migration.

Limitations and Risks

Specifications are not perfect:

  • They vary between runs due to model stochasticity;
  • Depend on prompt and model quality;
  • Lack legal precedent;
  • Do not replace patents or NDAs.

Additional measures:

  • Exclude secrets (API keys, PII) before analysis;
  • Focus on unique logic, not common patterns;
  • Use private models (o1, Claude 3.5 Sonnet with local storage).

Key Takeaways

  • New asset: SPEC.md captures architecture as a standalone object, strengthening your position in disputes.
  • Easy implementation: Generation takes minutes without altering processes.
  • Scalability: Apply to microservices, monoliths, or legacy code.
  • Safety first: Never analyze confidential data in public APIs.
  • Legal value: Proof ante factum, but consult with lawyers.

This approach shifts the paradigm: from protecting lines of code to protecting the system. Implement it for key projects today.
