What you cannot safely skip is making the project’s purpose, data, boundaries, and review requirements clear. Start with a small brief and a simple sketch of the main parts; then use AI for bounded changes that a human can inspect, test, and approve.
What to decide before asking AI to write code
Describe the problem before choosing a framework or requesting implementation. A useful first brief answers five questions:
As an Amazon Associate I earn from qualifying purchases.
- Who will use it? Name the intended users and what they need to accomplish.
- What is the core job? State the problem the software solves in concrete terms.
- What is the smallest useful version? Identify the essential behavior that would make a first release worthwhile.
- What data does it handle? Note what the software collects, stores, displays, or sends elsewhere.
- What is out of scope? List features and integrations you are deliberately postponing.
NIST’s DevSecOps reference model places requirements, architecture, secure design, and resources for addressing threats and defects in the planning phase. Its reference model also describes AI assistance in planning and development, but generated work still goes through review and validation.

Before implementation, ask the assistant to identify ambiguities, assumptions, and risks in the brief. Treat its answers as questions to resolve, not as proof that the project is ready to build.

Sketch the architecture without learning a whole discipline first
For a small project, a useful architecture sketch can be a few labeled boxes and arrows. It is not a formal blueprint; it is a way to make responsibilities and data movement visible.
- Interface: Where a person interacts with the software, such as a web page or mobile screen.
- Application logic: The part that applies the project’s rules and decides what happens after an action.
- Storage: Where information is kept, such as a database or file store.
- Outside services: Any third-party service the application calls, such as a payment or email service.
- Data flows and access: What information crosses each boundary, and which component can read or change it.
Mark uncertain choices rather than hiding them. Keep the first design understandable, and add components only when a real requirement calls for them. OWASP’s Secure by Design Framework includes architectural principles such as least privilege and isolation; in practice, this means limiting each part to the data and capabilities it needs.
Rank #2
Use AI to explore choices, not to make them for you
Once the brief and sketch exist, ask the assistant to explain the proposed design in terms you can evaluate. For each component or service, ask:
- What responsibility does it have, and what does it not do?
- What data enters or leaves it?
- What could fail, and what happens when it does?
- What is the simpler alternative, and what would be lost by choosing it?
- Which assumptions or decisions require a human to choose?
A confident explanation can still omit a constraint or propose unnecessary complexity. NIST’s Secure Software Development Framework (SSDF) is a lifecycle framework for integrating secure development practices, not a guarantee that a particular design is safe. Its SP 800-218 publication explains why security practices need to be incorporated into software-development lifecycles.
Rank #3
Turn the design into small, reviewable changes
Do not ask an AI tool to build the entire application in one go. Break the work into changes with a clear boundary and a way to check the result. For each task, specify:
- The behavior to add or change.
- The files or component boundary involved, if you know them.
- Constraints, such as data that must not be exposed or behavior that must remain unchanged.
- How success can be checked, such as a test or a particular visible result.
- Ask for a plan. Have the assistant list tasks and dependencies before it edits anything.
- Clarify unfamiliar choices. Ask why a component or package is needed and what a simpler option would be.
- Choose one bounded task. Prefer a change small enough to inspect and undo.
- Review the proposed change. Check its scope and whether it matches the intended behavior.
- Run the relevant tests. Examine the actual output; do not rely on a generated statement that tests passed.
- Approve or revert before moving on. Keep changes that you understand and can verify, and undo the rest.
NIST’s DevSecOps model describes AI assistance for generating work items, decomposing requirements, and generating code and tests. It also states that AI-generated outputs are reviewed through established processes including peer review, security validation, automated testing, and approval workflows. A small project may not have a formal review team, but the principle still applies: someone accountable needs to inspect and approve each material change.

Choose a tool by its workflow and access
Tools can range from interactive coding suggestions to agents that perform several steps or edit multiple files. GitHub’s documentation describes Copilot use across IDE, CLI, website, app, and SDK surfaces; that documentation describes product availability, not an independent ranking of tools. See Where to use GitHub Copilot for those documented surfaces.

- Task shape: Is the job an inline suggestion, an explanation, or a multi-step change across files?
- Access and autonomy: Can the tool only suggest text, or can it edit files, run commands, install packages, access the network, or use external services?
- Context exposure: What source code, terminal output, repository material, or credentials might be sent to the service?
- Reviewability: Can you inspect, test, attribute, and approve the proposed change before it is accepted?
- Project risk: Does the project handle sensitive data, have financial or safety consequences, or depend on authentication and outside integrations?
More autonomy makes permissions and review more consequential. OWASP’s Secure Coding with AI Cheat Sheet discusses agent trust boundaries and the possibility that coding tools expose code context that includes sensitive information. Give a tool only the access needed for its current task, and do not provide secrets unless you have a clear, approved reason and understand how they will be handled.

Generated code can appear to satisfy a visible feature request while missing security or architectural constraints. Treat changes as proposals, especially when they affect data, permissions, dependencies, or external services.
- Verify suggested packages before installing them. Check the exact package name and its provenance. OWASP warns that AI coding workflows can produce hallucinated dependency suggestions, including package names that may not be legitimate.
- Treat repository content as untrusted input. Issues, pull requests, documentation, and other files may contain malicious or misleading instructions aimed at an AI agent. Review actions prompted by that content rather than letting it expand the agent’s authority.
- Restrict permissions. Limit access to files, tools, commands, and services that the task needs. Use a human approval step for material actions.
- Inspect data handling. Check what information is stored, transmitted, or exposed, and whether the change respects the intended boundaries.
- Keep a human owner. A person must be responsible for review, approval, security, and maintainability—not just for typing the original request.
NIST SP 800-218A supplements the SSDF with secure-development practices for generative AI and dual-use foundation models. It is AI-specific guidance, not a turnkey architecture curriculum for someone building a small application. See the SP 800-218A publication.
Know when a project needs more than an AI assistant
The approach above is most appropriate when the project is modest, its requirements are understandable, and a responsible person can review its behavior and changes. Pause and get qualified help if you cannot explain how sensitive data is protected, the software makes high-impact decisions, or you are unsure how authentication and external integrations should be secured. AI can help surface questions, but a generated answer is not a substitute for accountable security review.
For ongoing work, NIST’s SSDF offers a lifecycle vocabulary for adding security practices to development rather than treating security as a final step. Use it as a guide to practices and review, not as a claim that following a checklist alone proves an application secure.
