ALREADY BUILDING WITH AI?

Your agent says it’s done. See what still needs checking.

Paste your coding-agent conversation. Get a short review of supported claims, visible problems, and useful next steps.

A separate review focused on the material you provide and the gaps that matter. It does not run code or independently verify outcomes.

Open your evidence workspace: saved audits, repair comparisons and practice

Reviews analyze supplied material. They do not independently run your code or verify a deployment.

RESEARCH CONTEXT

A confident summary is not the whole picture.

These studies describe specific security risks in different populations. They do not measure Second Opinion’s accuracy or predict the quality of your project.

10×the rate of security findings
AI-assisted developers commit 3–4× faster than their peers but introduce security findings at 10× the rate, across Fortune 50 codebases.
45%of AI-generated code carries an OWASP Top 10 flaw
Veracode's Spring 2026 GenAI code security study, testing more than 100 models on security-sensitive tasks.
35CVEs traced to AI-generated code in a single month
Georgia Tech's Vibe Security Radar recorded 6 in January 2026, 15 in February and 35 in March — a rising curve, not a plateau.
26%of published agent skills contain a vulnerability
A study of 31,132 AI agent skills found 26.1% contained at least one flaw — prompt injection, data exfiltration or privilege escalation.
