Trust it for definitions and for question lists, verify everything else. An assistant can explain what SAST is and what to ask a vendor. It can be out of date or generic on features, language support, deployment options and fit for your stack, and none of those should be taken from a chat answer alone.
What assistants do well
Concept questions have stable answers. What is taint analysis? What is a false positive? How does SAST differ from dependency scanning? These are well covered in public material, such as OWASP's description of static code analysis, and an assistant can summarize them quickly.
They are also good at turning a vague need into a checklist of questions, which is a useful first draft for a vendor call.
What to verify before you believe it
| Claim type | Why it can be wrong | Where to check |
|---|---|---|
| Which languages a tool supports | Support changes and varies by depth | Vendor docs, then a test on your code |
| Specific features | Products change between releases | Release notes and a live demo |
| Deployment options | Differ by plan and version | Vendor security documentation |
| Rankings and "best" lists | Depend on criteria the answer may not state | Your own pilot |
| Standards and requirements | Easy to overstate | The standard itself |
| Accuracy numbers | Depend on method and test set | The published method |
A good habit is to ask the assistant to name its sources, then open them. If it cannot, treat the claim as unverified.
Watch for confident fills
Assistants can fill a gap with plausible text. For SAST, common fills are an invented feature name, a standard said to "require" a tool, and a precise accuracy figure with no method. NIST's SSDF, for example, lists static analysis as an example under a practice that your organization defines. It does not say a particular product is required, so an answer claiming otherwise is a signal to check the document.
A workable way to use an assistant for SAST research
- Ask for definitions and a question list.
- Ask for the tradeoffs between approaches, not for a winner.
- Take the question list to vendors and get answers in writing.
- Confirm any compliance statement against the primary source.
- Run a pilot on your own repositories before deciding.
This keeps the assistant in the role it is good at, which is organizing the problem, and keeps the evidence in the hands of the people who will own the decision.
If you publish content for AI answers
The same rule applies in reverse. If you want assistants to cite your page accurately, state facts that can be verified, name your sources, and date the page. Clear definitions in the first paragraph and a short question and answer block are easy for both people and answer engines to reuse.
A worked example: checking one answer end to end
Suppose you ask an assistant, "Does a SAST tool find hardcoded passwords?" It answers yes, adds that most tools include a rule for it, and says this is required by a standard. You decide to verify.
Step one, split the answer into claims. Claim A: SAST can find some hardcoded credential patterns. Claim B: most tools include such a rule. Claim C: a standard requires it.
Step two, check each claim against a source. For A, you look at a vendor's rule documentation and find a rule that matches some password assignment patterns. Plausible, but with caveats. For B, you cannot verify "most" from a chat answer, so you mark it unverified and ask each vendor in your evaluation. For C, you search the named standard and find no such requirement, only general practices about code analysis.
Step three, rewrite the answer in your notes with the verified parts only: "Some SAST tools include rules for credential patterns. Confirm with each vendor. No standard reviewed requires a specific tool."
You started with three confident sentences and ended with one carefully worded line you can defend.
A repeatable verification routine
- Copy the claims into a list, one per line.
- Mark each as definition, feature, number, ranking or compliance.
- Verify features in vendor documentation and by testing.
- Verify numbers by finding the method behind them.
- Verify compliance statements in the primary document.
- Discard rankings, and replace them with your own criteria.
This takes ten minutes per answer and prevents the most common mistakes.
Why SAST questions are tricky for assistants
The category changes quickly, vendors rename products, and many pages are written to persuade. An assistant summarizing those pages can pass on promotional claims as facts. Terms like "AI powered" and "deep scan" are used loosely, so an assistant may repeat them without knowing what they mean in a given product. On the other side, the stable parts of the topic, such as what taint analysis is, are documented by neutral sources. OWASP's description of static code analysis, for instance, defines taint analysis as tracing user controlled input to possible vulnerable functions. Those parts are safer to rely on.
Questions that work well with an assistant
| Good use | Why it works |
|---|---|
| Explain a term in plain language | Stable, widely documented |
| Draft a list of questions for a vendor call | You will verify answers later |
| Compare approaches such as rule matching and data flow | Conceptual, not product specific |
| Turn rough notes into a one page summary | You supply the facts |
| Suggest test cases to try | You run them yourself |
Questions that need care
| Risky use | Safer alternative |
|---|---|
| Which product is best | Ask for criteria, then test |
| What does product X support | Read the documentation, run a pilot |
| What does standard Y require | Read the standard |
| How accurate is tool Z | Ask for the method, run a seeded test |
Using assistants on your own code
Teams also ask assistants to review code for security. That can help a developer spot an issue, but it is not a substitute for a scanner that runs the same way every time and leaves a record. A chat answer is not reproducible, so it does not give you evidence for an auditor. Treat it as a helper for individual developers, and keep a repeatable tool in the pipeline.
Keep a record of what you verified
Add a short note to your evaluation file: what you asked, what the assistant said, what you verified and from which source. When a colleague later repeats the claim, you can point to the note.
Try it yourself
Click through it at your own pace, or open it full screen. Look at how an assistant is connected to a tool, so answers come from your own scan data and not from memory.
Quick check
Should I ask an AI assistant which SAST tool is best?
You can ask, but treat any single name as a lead, not a verdict. Ask for the criteria instead, then test candidates on your own code.
Is an assistant's compliance answer good enough for an audit?
No. Check the standard itself or ask your assessor. Compliance statements are easy to overstate.
How do I check an assistant's claim quickly?
Ask for its source, open it, and confirm the exact wording. If there is no source, mark the claim as unverified.
