The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructs the installation of the markitdown package and its optional components (such as pdf, docx, pptx, xlsx, az-doc-intel, and youtube-transcription) via pip install as seen in SKILL.md and examples/basic/first-commands.md. These downloads originate from PyPI.
[INDIRECT_PROMPT_INJECTION]: The skill is configured to ingest and process data from untrusted external sources.
Ingestion points: The tool accepts local file paths, standard input stream (stdin), and remote HTTP/HTTPS URLs as input for conversion, as detailed in SKILL.md and the batch scripts in examples/advanced/workflows.md.
Boundary markers: The instructions do not mandate the use of delimiters or specific safety markers when the agent processes content retrieved from these sources.
Capability inventory: The skill enables file system reads/writes and network requests (via the tool's URI conversion feature). It also includes shell scripts that automate file processing across directories.
Sanitization: The skill lacks explicit sanitization or validation steps for the content or metadata of the files and URLs it processes.
