pptx — agentic threat model
This agent presents a moderate-to-high risk profile due to its ability to unpack, edit, and repack raw XML files and execute scripts (thumbnail.py, pptxgenjs) on user-provided presentation files, which could lead to arbitrary file manipulation or code execution if malicious inputs are processed.

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.
Uses Anthropic's foundation models. Vulnerable to prompt injection via malicious text, notes, or comments embedded within uploaded .pptx files, which could hijack the model's instructions during extraction.
Processes user-uploaded .pptx files using markitdown for text extraction. Vulnerable to data poisoning or XML External Entity (XXE) style attacks if the underlying XML parser does not safely handle untrusted presentation files.
Orchestrates multiple tools including pptxgenjs, thumbnail.py, and unpack/pack scripts. Risk of tool misuse or command injection if the agent fails to sanitize inputs passed to these local scripts and command-line utilities.
Not certain from the listing — requires a secure, sandboxed execution environment to run Python (thumbnail.py) and Node.js (pptxgenjs) safely. If unsandboxed, a compromised agent could achieve local file system access or remote code execution.
Not certain from the listing — lacks explicit mention of logging, run-time guardrails, or output validation to ensure generated XML or scripts do not contain malicious payloads or violate safety policies.
Not certain from the listing — no details are provided regarding access control, user authentication, or compliance certifications (e.g., SOC2) governing how user-uploaded presentation data is stored or isolated.
Operates primarily as a single-purpose skill for presentation editing. Low multi-agent risk unless integrated into a larger workflow where it passes unvalidated XML or extracted text to downstream agents.
