security-guidance — agentic threat model
This agent functions as a security-focused plugin for Claude Code, operating primarily via hooks to review local code edits and diffs. Its risk posture is low because it acts as a passive, local analysis tool with minimal autonomy, though it possesses access to local source code and execution context.

MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Utilizes Anthropic's foundation models (via Claude Code integration) to perform LLM-powered diff reviews. Threats include adversarial prompt injection within analyzed source code designed to bypass security checks or trigger misaligned outputs during review.
Operates locally on session diffs and file edits. It does not maintain an independent vector database or complex RAG pipeline, but it is exposed to potentially malicious code inputs that could attempt data exfiltration if the plugin logs or transmits findings.
Integrates directly into Claude Code using PostToolUse and Stop hooks. Framework threats include bypass of these hooks by malicious code, or insecure tool integration where the plugin's own analysis logic is manipulated to execute arbitrary commands.
Runs locally within the user's development environment (Claude Code CLI context). If the host environment is unsandboxed, a compromise of the plugin or the underlying agent could lead to local privilege escalation or unauthorized file system access.
Acts as an observability and guardrail tool itself by pattern-matching edits and flagging vulnerabilities. However, blind spots in its 25+ vulnerability classes or evasion of its LLM-powered diff reviewer represent significant risks.
Designed specifically to enforce security policies and prevent vulnerabilities (injection, XSS, SSRF, secrets) from being committed. It lacks its own complex identity/authorization layer, relying entirely on the host CLI's permissions.
Operates as a plugin within the Claude Code ecosystem. While it reviews actions of the primary coding agent, a compromised primary agent could attempt to disable, bypass, or spoof the hooks of this security plugin.
