The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructions recommend installing the python-pptx library from the Python Package Index (PyPI), a well-known and standard package registry.
[COMMAND_EXECUTION]: The skill utilizes the run_shell tool to execute Python code at runtime to inspect presentation structures. This activity is aligned with the skill's primary stated purpose of providing deep file validation.
[INDIRECT_PROMPT_INJECTION]: The skill represents a surface for indirect prompt injection because it ingests and processes content from untrusted PowerPoint (.pptx) files and reflects that content back into the agent's context without sanitization.
Ingestion points: Reads .pptx files using the python-pptx library (SKILL.md).
Boundary markers: None present; the extracted slide titles and metadata are printed directly to standard output.
Capability inventory: The skill has access to the run_shell tool and pip package manager.
Sanitization: There is no escaping or filtering of the text extracted from slide shapes or titles before it is processed by the agent.
