Behavior test recordsCASE 01 · Input & response

Illustrative agent security assessment, not a live scan. All objects and test content are fictional. Load a document assistant and its runtime, then map its model, Skills, Plugins, MCP and API dependencies. A prompt injection test introduces external content that tries to redirect a summarization task. The observed DONE response is recorded as an instruction deviation risk for review. Model AI-BOM, extension checks and behavior test records support pre-deployment review. Dependency lines do not indicate attack propagation. AI-BOM is scoped to the model. This does not imply automatic blocking, a confirmed vulnerability or deployment approval.

PRODUCT OVERVIEW

Assess risk acrossthe agent supply chain

Assess vulnerabilities, malicious files, content safety and license compliance across agents, foundation models and runtime dependencies

Combine agent behavior tests, foundation-model verification, model-file inspection and interface testing. Map model composition with an AI-BOM to guide remediation before deployment

CORE CAPABILITIES

USE CASES

Use cases

01 — 03

LLM compliance before filing

Self-assess model outputs against GB/T 45654-2025 and address compliance risks to improve the chance of passing the first filing review

Foundation-model provenance

Trace open-source foundation-model origins, versions and derivatives. Build an AI-BOM to understand supply-chain composition and provenance and strengthen governance

Pre-deployment agent assessment

Assess external-facing agents for non-compliant content and malicious exploitation risks before production deployment to support remediation and release review
