aws-cost-saver — agentic threat model
The aws-cost-saver agent poses a moderate security risk primarily centered on read-only credential exposure and cloud metadata exfiltration, as it requires access to AWS account states to perform its 173 cost checks.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
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 — relies on Claude (via Claude Code) as its foundation model. Risks include prompt injection manipulating the cost recommendations or tricking the model into misinterpreting AWS resource states.
Ingests AWS account state data and real-time AWS pricing API data. Risks include the exposure or exfiltration of sensitive cloud infrastructure metadata and resource configurations during the analysis process.
Runs as a Claude Code plugin executing 173 cost-optimization checks. Risks include insecure tool integration where the tool execution path could be hijacked to run arbitrary AWS CLI commands beyond cost checking.
Not certain from the listing — likely runs locally within the user's terminal/environment where Claude Code is installed. Risks include local credential theft if the host environment is compromised.
Not certain from the listing — no explicit evaluation, guardrails, or logging mechanisms are mentioned. Risks include a lack of auditability regarding which AWS API endpoints the plugin queries.
Relies on the user's local AWS IAM credentials to read account state. Risks include over-privileged IAM roles (e.g., AdministratorAccess instead of ReadOnlyAccess) being abused by the plugin.
Operates as an open-source plugin within the Claude Code ecosystem. Risks include supply chain attacks where malicious updates are introduced to the open-source repository.
