Building Your Own Vulnerability Harness

Security analysis that relies on a single LLM has limitations in that it only explores certain paths in the code due to the model's logical bias. To solve this, a Model-agnostic harness structure that treats models as replaceable components is needed.

The core architecture for effective security verification is as follows:

• Cross-model verification: Increase detection rates by cross-deploying models with different logical systems, such as using Model A for initial exploration and Model B for verification.
• Agent orchestration: Rather than a simple prompt-based sub-agent approach, an orchestration layer with state control, deduplication, and resumability must be built.
• 7-stage audit process: Reliability is secured through the stages of Recon → Hunt (attack simulation) → Validate (refuting results) → Report (writing the report) → Mechanical Check (schema validation) → Re-verify (independent re-verification).

This harness structure enables a sustainable enterprise-grade security scanning pipeline regardless of changes in the performance of a specific model or service outages.
