hook-complexity-monitor — agentic threat model
The hook-complexity-monitor presents a moderate security risk primarily driven by its integration as a local development hook within Claude Code. While its direct autonomy is low, a compromise of this plugin could allow attackers to inject malicious refactoring prompts or exfiltrate sensitive source code from the developer's local environment.

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.
Not certain from the listing — The plugin likely relies on Claude Code's underlying model to generate refactoring prompts. Threats include prompt injection where malicious code being analyzed manipulates the refactoring prompt generation.
The plugin directly accesses and processes local source code files during edit hooks. Threats include data exfiltration of intellectual property if the plugin's telemetry is compromised, or local code exposure.
It integrates as a hook-based plugin within the Claude Code agent framework. Threats include insecure tool integration, where the hook execution could be hijacked to run arbitrary commands or bypass framework constraints.
Not certain from the listing — It runs locally within the user's development environment where Claude Code is executed. Threats include local privilege escalation or container escape if the host environment is not properly sandboxed.
The plugin acts as an observability tool monitoring cyclomatic complexity. Threats include blind spots where complex or malicious code bypasses the parser, or evaluation gaming where developers write bad but low-complexity code to bypass the hook.
Not certain from the listing — No explicit authentication, authorization, or compliance controls are mentioned. It likely inherits the permissions of the host Claude Code process.
As an open-source plugin, it represents a supply chain risk in the agent ecosystem. Threats include supply chain attacks where a compromised version of this plugin is distributed to developers, leading to repository compromise.
