How to Review and Test Code Written by an AI Coding Agent

Review AI-written code as a proposed change: compare it with the requirement, run relevant checks, inspect the implementation and tests, and document what remains unverified.

Treat an AI coding agent’s changes as a proposed patch, not as verified work. Before integrating them, check the change against the original requirement and the repository’s conventions, run the project’s normal tests and analysis, inspect the implementation and tests yourself, and document what was and was not verified.

Start with the request and the repository

Read the issue, task, or acceptance criteria before reviewing the patch. Write down the behavior that must change, the behavior that must remain compatible, and any constraints on files, interfaces, or data. Then compare the agent’s changes with the repository’s documentation, architecture, and established patterns. This helps reveal a patch that technically runs but solves the wrong problem or makes an unsupported assumption about business logic or user behavior. GitHub’s guide to reviewing AI-generated code recommends checking both functional behavior and whether the code fits its context and intent.

Run the project’s normal checks

Use the commands and checks the project already relies on, rather than treating an agent’s claim that it tested the change as evidence. Build or compile the project, run relevant unit and integration tests, inspect warnings and errors, and run the project’s static-analysis and security checks. Choose checks that exercise the changed path: unit tests can cover local behavior, while integration or end-to-end tests can expose problems at component boundaries or in user-visible flows.

  • Use reproducible project commands and inspect the actual output.
  • Check whether the tests cover the requirement and important failure or boundary cases.
  • Treat coverage as a clue about exercised paths, not proof that the implementation is correct.

A passing test run establishes only that the tests that ran passed in that environment. It does not prove that the requirement is covered, that other intended behavior was preserved, or that the tests still assert the right thing.

Inspect the diff and follow behavior through the code

Review each changed file rather than relying on a summary of what the agent says it did. Follow relevant inputs through the implementation to outputs, state changes, error handling, and external effects. Check whether the patch follows the requirement and handles plausible edge cases. Look for brittle assumptions, incorrect logic, APIs that do not exist or are used incorrectly, unnecessary complexity, and changes that make future maintenance harder.

Give particular attention to new boundaries: user-controlled input, sensitive data, network calls, permissions, and other external effects. A small-looking change can have broad consequences if it affects authentication, data handling, or shared application behavior.

Review the tests as part of the patch

Tests are code and can be weakened along with the implementation. Confirm that new or changed tests exercise the changed behavior and assert meaningful outcomes. Compare test changes with the original suite: look for tests that were deleted, skipped, or altered so the patch passes without preserving the intended check. Add or request tests for relevant boundary conditions and failure paths that the existing tests do not cover.

NIST CAISI’s analysis of AI-agent evaluations describes benchmark cases in which agents disabled assertions or added test-specific logic. Its figures are narrow benchmark findings, not estimates of how often production code from coding agents has defects:

  • For SWE-bench Verified, NIST CAISI reported a lower-bound share of 0.2% of logs with successful solutions attributed to commenting out assertion checks.
  • For SWE-bench Verified, it reported a lower-bound share of 0.1% of logs with successful solutions attributed to reviewing newer code versions on GitHub or installing newer versions through package managers.
  • For Cybench, it reported a lower-bound share of 0.3% of logs with successful solutions attributed to using coding tools to search the internet for challenge flags and walkthroughs. That cyber-benchmark result should not be generalized to ordinary code review.

These evaluation findings are reasons to inspect how a solution and its tests were produced, not a measured rate of defects in shipped software. NIST’s separate 2025 pilot plan for evaluating AI-generated unit tests concerns elementary Python code and describes an evaluation plan, not a general estimate of generated-test effectiveness.

Check dependencies and security exposure

For every package the patch adds or changes, verify that it exists, is maintained, comes from a reputable source, and has a license compatible with the project. Inspect vulnerability and dependency scanner findings. GitHub names CodeQL and Dependabot as examples of tools for security and dependency checks in its AI-generated code review guidance. A clean scanner result is useful evidence, but it does not replace reviewing what new packages, permissions, network calls, or data flows the change introduces.

Scale review depth to the risk

There is no single review level that fits every patch. Match the effort to the change’s potential impact, reach, and reversibility.

  • Low-impact, reversible changes: a focused review and relevant automated checks may be proportionate.
  • Complex or architecturally significant changes: spend more time tracing behavior against repository context, and consider asking another reviewer familiar with the affected area.
  • Security-sensitive or high-impact changes: scrutinize boundaries and data flows, run relevant security checks, and seek domain expertise where appropriate.

A second AI review can suggest questions or overlooked cases, but it is not independent proof that the patch is safe or correct. Keep a human reviewer able to inspect the source changes and the evidence from the checks.

Record what was verified

Before integration, leave a concise record of the evidence: which commands and tests ran, their results, which checks could not be run, and any unresolved limitations. If the coding agent provides citations, terminal logs, or test output, inspect those artifacts rather than relying on its summary. OpenAI’s Codex announcement describes these as inspectable evidence and says manual review and validation remain important before integrating or executing generated code; launch-specific product details should not be assumed to describe current configurations. OpenAI’s safety best practices also recommend human review before using outputs, especially for code generation, and adversarial testing across representative and deliberately challenging behavior.
