You've built something with AI. The code runs on your laptop, the feature works in the demo, but now you need to ship it to real users. That's where most AI-assisted projects hit friction. The code that feels complete in Cursor or Claude often lacks the guardrails, tests, and safeguards that separate a prototype from a production system. This checklist gives you the concrete steps to close that gap.

TL;DR

  • AI-generated code works differently in production than in development, you need a shipping mindset, not just a working prototype.
  • Verify every layer: security, error handling, performance, and data integrity before you deploy.
  • Use code review, automated testing, and monitoring to catch what humans and AI miss.
  • The real question is not whether AI can create code. It's whether you can ship it responsibly.

Shipping AI-assisted code requires the same discipline as shipping any code, plus one extra filter: skepticism toward the AI output. When you use Cursor, Copilot, or Claude to generate features, you get speed but you also inherit invisible assumptions, missing error handlers, unvalidated inputs, side effects the AI didn't flag. Between "it works locally" and "it's live" sits a deployment checklist. This guide walks you through that gap.

Why AI-Assisted Code Needs Extra Scrutiny

0%
AI Code Shipped Without Review

AI can write syntax-correct code that compiles and runs, yet fails in production. The gap exists because AI doesn't see your infrastructure, your edge cases, or your failure modes. It doesn't know that your payment processor times out after 3 seconds, or that your database resets every night for testing, or that users in Southeast Asia experience 500 ms latency.

When you ask an AI to build a feature, it delivers code that satisfies your prompt. That's different from code that handles production reality: concurrent requests, malformed inputs, network partitions, disk full, and a thousand other conditions that exist nowhere in the training data.

"The real question is not whether AI can create code."
>, AI Coding Workflow Checklist Before You Ship

The reality: shipping AI code is not about trusting the AI. It's about trusting your process. A checklist enforces that process.

Common Mistakes When Shipping AI Code

Before you build, know what fails:

  • Skipping code review. The AI output looks right; review feels redundant. It's not. Developers miss subtle bugs in human code; AI code introduces bugs humans wouldn't write, like missing null checks or hardcoded secrets.
  • No error handling for external dependencies. AI often generates happy paths. API calls succeed. Files exist. Databases respond. Production is different.
  • Insufficient test coverage. AI-generated tests pass because they test what the AI thinks the code should do, not what it actually does under load or with edge inputs.
  • Deploying without monitoring. If something breaks, you want to know within minutes, not when a customer reports it. AI-assisted codebases often lack instrumentation.
  • Security assumptions baked into the code. AI doesn't flag that a user-facing endpoint lacks authentication, or that SQL queries need escaping, or that secrets shouldn't be logged.

Step-by-Step Deployment Approach

1. Audit the Code for Security

Start here. AI code often has security blind spots.

  • Check for hardcoded secrets. Grep for API keys, database passwords, tokens. AI sometimes includes them as placeholders. Remove them now.
  • Verify input validation. Every endpoint, every function that accepts user input, does it validate type, length, and format? AI skips this often.
  • Review authentication and authorization. Is every protected endpoint actually protected? Does the code verify that the user owns the data they're accessing?
  • Inspect SQL/database queries. Are they parameterized? AI generates vulnerable queries when you don't explicitly ask for protection.
  • Check for unsafe deserialization. If your code parses JSON, YAML, or pickled data, is it using safe parsers?
Use a tool like Semgrep, Snyk, or your IDE's built-in security scanner. These catch patterns that humans and AI both miss.

2. Validate Error Handling

Proper Error Handling Coverage
0%

AI writes success paths beautifully. Failure paths are optional in its mind. You need them mandatory.

For every external call, database, API, filesystem, network, ask:
  • What happens if this times out?
  • What if it returns an error code?
  • What if the response is malformed?
  • Should the entire request fail, or should we retry/fallback?
Walk through the code with these questions. Mark every uncaught exception, every unhandled edge case. AI tends to write: 
result = api.call()
return result

You need:

try:
  result = api.call(timeout=3)
  if result.status != 200:
    log_error(result)
    return fallback_value
  return result
except TimeoutError:
  return cached_result or fallback
except Exception as e:
  alert_team()
  raise

3. Write Tests That Match Reality

AI generates tests that verify the happy path. You need tests for the crash paths.

  • Unit tests: Each function with its edge cases. Test with None, empty strings, negative numbers, enormous inputs.
  • Integration tests: Real database, real API calls (or mocks). Does the full flow work?
  • Load tests: Can it handle 10 concurrent requests? 100? Where does it break?
  • Error injection: Simulate timeouts, connection failures, database unavailability. Does the code handle them?
Use pytest (Python), Jest (JavaScript), or your language's standard. Aim for 70%+ code coverage on the paths that matter. AI-generated code often has low test coverage; you're raising it to production standards.

4. Set Up Monitoring and Alerting

Monitoring is your early warning system. You want to catch production issues minutes after they happen, not days.

  • Application metrics: Response time (p50, p95, p99), error rate, throughput. Track these over time.
  • Infrastructure metrics: CPU, memory, disk, network. Does the code leak resources?
  • Business metrics: Successful transactions, failed payments, user actions. Does the feature behave as intended?
  • Logs: Structured logs with context. When something breaks, you need to understand why.
Use Datadog, New Relic, CloudWatch, or open source equivalents like Prometheus + Grafana. Set up alerts so you hear about problems before customers do.

5. Code Review (Mandatory)

Even if it's just you and one other person, do a code review. AI code needs a second pair of eyes.

Reviewers should check:
  • Logic correctness. Does the code do what the ticket asked?
  • Performance. Are there N+1 queries, infinite loops, or wasteful operations?
  • Maintainability. Can someone other than the author understand this in six months?
  • Consistency. Does it follow the team's style, patterns, and conventions?
Pull request comments like "why did you do it this way?" often expose assumptions the AI baked in without realizing. Push back on unclear code. Ask for clarification or refactoring.

6. Performance Testing

AI doesn't think about scale. Your code will.

  • How fast does each endpoint respond? Aim for sub-500ms at p95 for user-facing requests.
  • How many concurrent users can the system handle? Use tools like Apache JMeter or k6 to simulate load.
  • Does database performance degrade as data grows? Test with 10x your current data volume. Are there missing indexes?
  • Are there memory leaks? Run the application for hours under load and watch memory usage.
Performance problems caught in staging save you from customer meltdowns in production.

7. Deploy to Staging First

Never ship directly to production. Staging is your final test before real users see the code.

  • Use the same infrastructure as production. Staging should mirror production as closely as possible, same database engine, same environment variables, same deployment process.
  • Run your full test suite against staging. This is where integration tests matter; they exercise the real system.
  • Smoke test manually. As a user, try the feature. Look for rough edges, unexpected behavior, crashes.
  • Monitor staging as you would production. Watch logs and metrics as you use the feature.
If anything looks wrong, fix it, and re-test. Staging is cheap; production is expensive.

8. Document What the AI Built

AI code often lacks documentation. You need it.

  • Why does this code exist? What problem does it solve?
  • What are the assumptions? What will break if these assumptions change?
  • How do you operate it? If something goes wrong, what do you do?
  • What are the limits? Can it handle 1 million requests? What happens at 10 million?
Write a README. Add code comments for non-obvious sections. Document the deployment process, rollback procedures, and monitoring setup.

FAQ

Frequently Asked Questions

This guide is for anyone shipping AI-assisted code to production. Whether you're a founder using Cursor to build your startup, a developer integrating Copilot into your workflow, or an engineering lead adopting AI across your team, you need this checklist. The principles apply whether you built 50 lines of code or 5,000.
It depends on the scope of your code. A small feature (100-500 lines) might take 1-2 days from code to production. A larger feature or new system might take a week. The checklist doesn't add time; it prevents time-wasting firefighting later. The security audit, testing, and monitoring setup protect you from customer incidents that would consume days or weeks.
Start with the security audit. It's the highest-impact step and the fastest to fail. Run a secrets scanner, manually check for SQL injection vulnerabilities, verify that sensitive endpoints require authentication. You'll catch the most critical issues in 1-2 hours. Then move to error handling and testing in parallel. Code review can happen as you work.
Yes. AI generates tests that pass because the test exercises what the AI thinks the code should do, not edge cases or failure modes. For critical code, throw weird inputs at it, null values, enormous strings, negative numbers, concurrent requests. Your tests should fail at least once during development. If they don't, they're not testing enough.
No. Staging is cheap; production is expensive. A bug caught in staging costs an hour or two to fix. The same bug in production might cost thousands in customer impact, your time to debug and fix and redeploy, and reputation damage. Always deploy to staging first, run your full test suite, and manually verify the feature works.
You'll know when you can answer these questions in 30 seconds: Is the feature working right now? How many users are using it? What's the error rate? How fast is it? If you can't answer them by checking a dashboard, you need more monitoring. Set up dashboards for the metrics that matter to your business, and set up alerts so you're notified when something goes wrong.

Shipping AI-assisted code is not a one-time decision. It's a process you repeat with every feature, every update, every dependency. Each time you use an AI tool to generate code, you gain speed, but you trade away the certainty of understanding every line. A checklist gives you that certainty back. Use it, refine it, and make it part of your team's standard. Your future self, debugging a production incident at 2 AM, will thank you.
