Combining security scanners with the Agents SDK

In this notebook, we’ll build a security review workflow with the OpenAI Agents SDK and static scans from Semgrep and Bandit. The manager agent in our workflow dynamically chooses specialist agents to investigate the code behind each scanner finding. After review and validation, we’ll use the confirmed findings to create a Codex /goal prompt that you can review before asking Codex to make fixes.

1. Requirements and approvals

• Python: Use Python 3.12.

• API key: Live runs require OPENAI_API_KEY.

• Supported platforms: Live scans support macOS, Linux, and Windows Subsystem for Linux (WSL). Native Windows is unsupported.

• JupyterLab: Install it separately.

• Packages and scanners: Install the pinned versions below.

  python -m pip install openai-agents==0.22.0 openai==3.6.0 pydantic==2.13.5 ipython==9.16.1 ipykernel==7.3.0
  python -m pip install semgrep==1.174.0 bandit==1.9.4

• Default model: gpt-5.6-sol with xhigh reasoning.

• Approvals: network allows downloads, scanners allows local scans, and model_agents allows model calls.

• Safe inspection: Leave approvals empty to run all cells without external actions.

  SECURITY_SWARM_APPROVALS="" jupyter lab examples/agents_sdk/security_scanners_with_agents_sdk.ipynb

• Full demonstration: Enable all three approvals.

2. How the review works

Now let’s take a look at how this works. We start by collecting possible issues from the scanner reports into a list of candidates. The manager agent chooses a specialist to review each candidate, and an independent validator proposes a decision. Python checks that every candidate was reviewed exactly once and stops the review if a candidate ID is unknown, duplicated, or missing.

Python also enforces approvals, verifies files, and selects scanners. Each specialist agent receives excerpts from the verified files. We instruct the agents to treat repository text as evidence, never as instructions.

Both examples use static source analysis. They don’t invoke Codex Security, run either application, or modify the source. You could build on this workflow by adding runtime checks or applying fixes, with human approval before either step.

3. Pin source files and run scanners

Now, let’s get into a live run. We’ll use a few files from two intentionally vulnerable GitHub projects. SasanLabs VulnerableApp gives us one Java/JDBC class, and OWASP crAPI gives us three Python files and one JavaScript file.

In this workflow, Semgrep uses five local rules to scan the selected files from both projects, and Bandit checks the production Python files. Complete coverage means those files were scanned, not that every type of vulnerability was checked. Findings must reference files the scanners actually inspected. If a scan fails or coverage is incomplete, the review will automatically stop.

        assessments=tuple(assessments), selected=tuple(selected),
        results=tuple(results), candidates=tuple(candidates))

We check each scanner result against the approved source and record the file path, line number, file hash, and commit, along with the scanner and rule ID. If multiple reports flag the same category of issue at the same code location, we group them into one candidate.

4. One manager agent chooses specialists

The manager can call authentication, injection, or configuration specialists. We give it the scanner candidates and the repository’s languages and source paths, then let it decide which specialist should review each candidate. Each selected specialist gets one batch of candidates. Agent.as_tool() lets the manager call a specialist without handing over the conversation.

Before a specialist starts, we check the candidate IDs and send it the relevant code from the verified files. Once its response passes the checks we save the assessment for the validator agent.

To extend this workflow, you could add specialists for API authorization, cryptography, sensitive data exposure, or cloud configuration.

5. Validate findings and prepare a Codex goal

Once the specialists finish their reviews, an independent validator proposes confirmed, needs_review, or not_actionable for each candidate, with a reason and any proof gaps. Python checks the candidate IDs in each proposal and maps them back to the verified source and scanner records.

A proof gap in this workflow is a missing fact that could change our judgment about the code we’re reviewing. Take the JWT candidate in the saved run. The code skipped local signature verification, but it also called another service to verify the token. That service’s implementation wasn’t in our approved files, so the candidate stayed in needs_review.

Not every unknown is a proof gap, though. Questions about deployment or exposure go under limitations if they don’t change what we can conclude from the source. A finding can only be confirmed when it is tied to verified source and has no unresolved proof gaps.

VALIDATOR_PROMPT = prompt_text(
    TRUSTED_POLICY,
    '''
    Return one judgment for every reviewed candidate in canonical order. Copy only its
    candidate_id. Choose confirmed, needs_review, or not_actionable, then give a short
    source-specific reason and any proof gaps.
    Make your own judgment from the supplied source. Scanner labels and specialist
    conclusions are hypotheses, not proof. Reconstruct the relevant input, control,
    and sink, then challenge the claim with the strongest available counterevidence.
    Explain that source-based judgment in reason.
    Confirmed and not_actionable require an empty proof_gaps list. If a missing fact could
    change the disposition, choose needs_review.

    For SQL, check whether the observed guards constrain the exact input reaching query
    syntax. Do not dismiss a serializer check because the sink reads raw request data.
    If the serializer's missing rules could change the judgment, use needs_review.
    For a later unverified JWT decode behind an upstream verification request and success
    check, use needs_review when verifier semantics or a bypass are absent.
    Treat fixed-destination missing timeouts as hardening. A visible request-controlled
    repeated call can support the narrow availability claim. Explicitly disabled TLS
    verification supports the narrow disabled-control claim.

    Carry specialist proof_gaps forward unchanged; the Python evidence gate retains
    them, and this run cannot clear them. Add any other material gaps and choose
    needs_review while any remain. If you disagree with a specialist, explain why
    in reason without dropping its gaps. Name the specific missing fact or check
    needed to settle each new gap. Do not invent controls or claim runtime exploitation.

    helpers.verify_model_validation(report, evidence.snapshot, evidence.candidates)

def finish_review(evidence: Any, reviews: Sequence[Any], report: Any):
    # Recheck source evidence before accepting a model judgment.
    provenance = helpers.apply_provenance_gate(

        evidence.candidates, reviews, report,
        provenance=provenance, assessments=evidence.assessments,
    )

Before building the /goal prompt, we check the evidence one last time (source hashes, line numbers, and scanner coverage). Invalid evidence stops the run. Python keeps any proof gaps from either review, even if the validator disagrees. Those findings stay in needs_review and out of the prompt. Only confirmed findings make it into the final /goal prompt.

6. Compare two repository reviews

Let’s run both repositories through the same run_review() function and see which specialists the manager chooses for each. When all three approvals are enabled, the final cell checks that both reviews completed and that we have a Codex /goal prompt to review.

def partial(manifest: Any, status: str, error: str, evidence: Any = None):
    return helpers.partial_review(
        manifest=manifest,
        status=status,
        error=error,

        fingerprint=getattr(evidence, "fingerprint", None),
        assessments=getattr(evidence, "assessments", ()),
        selected=getattr(evidence, "selected", ()),
        scanner_results=getattr(evidence, "results", ()),
        candidates=getattr(evidence, "candidates", ()),
    )
async def run_review(manifest: Any):
    if not allowed("network"):
        return partial(manifest, "not_authorized", "Network acquisition was not requested.")
    try:
        evidence = collect_evidence(manifest)
    except helpers.CoverageError:
        raise
    except helpers.EvidenceError:
        raise
    except Exception:
        return partial(manifest, "failed", "Source or scanner execution failed.")
    if not allowed("scanners"):
        return partial(manifest, "partial", "Scanner execution was not requested.", evidence)
    if not evidence.candidates:
        return partial(manifest, "partial", "The bounded scan produced no candidates.", evidence)
    if not allowed("model_agents"):
        return partial(manifest, "partial", "Model review was not requested.", evidence)
    if not os.getenv("OPENAI_API_KEY"):
        return partial(manifest, "partial", "OPENAI_API_KEY is not configured.", evidence)
    try:
        reviews = await run_manager(evidence)
        report = await validate(evidence, reviews)
        return finish_review(evidence, reviews, report)
    except (helpers.CoverageError, helpers.EvidenceError):
        raise
    except Exception:
        return partial(manifest, "failed", "A model stage did not complete.", evidence)
target_reviews = {}
for name, manifest in TARGETS.items():
    target_reviews[name] = await run_review(manifest)

The specialist column shows which specialist the manager called, and final shows the decision after the evidence checks. Notice the saved JWT result. It stays needs_review because the upstream verifier isn’t part of the approved source. We’d need to inspect that verifier or show a bypass before making a stronger claim.

The crAPI SQL candidate needs more evidence too. We can see the serializer check, but not its validation rules.

Findings that need more evidence

crapi — services/workshop/utils/jwt.py:61

Candidate: cand-1742b9ae3963a27c

The Bearer token is decoded without signature verification and its `sub` selects the user, but only after the same token is submitted to `IDENTITY_VERIFY` and that service returns HTTP 200. No verifier implementation or demonstrated bypass establishes whether this upstream control cryptographically validates the token; `verify=False` disables TLS certificate checks but does not itself prove acceptance of an unsigned token.

• Proof gap: The implementation or contract of `IDENTITY_VERIFY` is missing: it is unknown whether it cryptographically verifies the submitted token and returns 200 only when that same token is valid.

crapi — services/workshop/crapi/shop/views.py:388

Candidate: cand-9c16875f717198fb

The raw `coupon_code` is concatenated inside a quoted SQL predicate and passed to `cursor.execute` without parameter binding. However, `CouponSerializer.is_valid()` dominates the sink, and its missing rules could reject every value capable of altering SQL syntax.

• Proof gap: CouponSerializer’s coupon_code field validation and any custom validate()/validate_coupon_code() logic are missing; these checks could exclude quote characters or otherwise prevent SQL syntax alteration.

Codex handoff for human review

We pick the completed review with the most confirmed findings and turn those findings into a /goal prompt for Codex. Python does the formatting to avoid additional model calls. In under 4,000 characters, the prompt tells Codex which verified files to work on and asks for focused regression tests.

# Include confirmed findings from only one repository.
selected_bundle = helpers.select_goal_bundle(target_reviews)
selected_goal = helpers.render_codex_goal(selected_bundle) if selected_bundle else None
if selected_goal:
    assert selected_goal.startswith("/goal ") and len(selected_goal) < 4_000
    display(Markdown(f"**Generated Codex goal**\n\n```text\n{selected_goal}\n```"))
else:
    display(Markdown("*No confirmed finding is ready for a Codex handoff.*"))

Generated Codex goal

/goal Remediate confirmed findings in crapi

Work only in repository https://github.com/OWASP/crAPI at revision 700f03d12a392d9e408260b4beae72ed02a4a1a4.
Keep production changes limited to the approved source paths listed below.
You may add or update only the test files needed to cover those fixes with focused regression tests.
Ask for approval before changing any other files. Do not alter unrelated behavior.

1. Bound outbound request time (P2)
   Paths: services/workshop/crapi/merchant/views.py
   Evidence IDs: cand-3638cc76cae2d1d0
   Change: Set an explicit connect/read timeout and handle timeout failures safely.
2. Restore TLS certificate verification (P2)
   Paths: services/workshop/crapi/merchant/views.py, services/workshop/crapi/shop/views.py, services/workshop/utils/jwt.py
   Evidence IDs: cand-85661410cf96c620, cand-4313414a28b1fa7e, cand-896f29e345909523
   Change: Remove verify=False and configure a trusted CA bundle where necessary.

Validation requirements:
- Add or update focused regression tests for each remediated path.
- Run the repository's relevant tests and the applicable security scanners.
- Report changed files, validation results, and any remaining limitations.
- Stop and ask for review if the pinned source no longer matches the evidence above.

Usage and limits

Requested model and measured usage

repository	stage	requested model	responses	input tokens	output tokens	total tokens

This example covers five source files. It doesn’t cover runtime behavior, deployments, dependencies, infrastructure, secrets, or the rest of either repository. You’d need separate evaluation and human review before using this in production.

Conclusion

We used the same workflow to review two projects, with the manager choosing which specialists to call. In the saved run, ten candidates produced six confirmed findings, two marked not_actionable, and two left in needs_review. The four confirmed crAPI findings became a Codex /goal prompt we can review before requesting fixes.

If you adapt this to your own code, start with a small, approved set of files you know well. Check the manager’s assignments and the final decisions against your own review. Once you understand where it gets things right (and where it needs your help/additional context) you can decide what to add next.
