The Agent Skills Directory

COMMAND_EXECUTION (LOW): The skill instructs the agent in SKILL.md to generate unique file identifiers by executing the system command openssl rand -hex 16. While the purpose is benign (random string generation), it encourages the use of shell/command execution tools on the host environment.
PROMPT_INJECTION (LOW): The skill's architecture is susceptible to indirect prompt injection because user-provided content drives a multi-stage automated process.
Ingestion points: User-provided topics and narratives are ingested into the slides_list.md file, which serves as the primary instruction source for subsequent automated steps.
Boundary markers: Absent. The agent interpolates untrusted user content directly into the markdown checklist without delimiters or instructions to sub-agents to ignore embedded commands.
Capability inventory: The skill has the ability to create directories, write files (.md, .excalidraw.md, .svg), execute shell commands, and invoke sub-agents via the Task tool.
Sanitization: Absent. There is no evidence of input validation, escaping, or filtering for user-provided strings before they are written to the outline and processed by the sub-agent.
