[EXTERNAL_DOWNLOADS]: The skill uses npx to fetch and run @missing-elements/h5p-normalize and @missing-elements/h5p-verify. These are vendor packages corresponding to the skill's author, 'missing-elements'.
[COMMAND_EXECUTION]: The instructions involve executing shell commands such as npx, curl, and unzip to process H5P archives and verify server header support.
[INDIRECT_PROMPT_INJECTION]: The skill processes H5P packages, which are ZIP archives containing user-controllable media and metadata, creating a surface for potential injection attacks.
Ingestion points: Files and URLs provided by the user for normalization, as specified in SKILL.md.
Boundary markers: None identified; the skill does not explicitly differentiate between its instructions and the data within the H5P files.
Capability inventory: Uses npx for tool execution, curl for network diagnostics, and unzip for archive testing, while also writing new .h5p files to the local system.
Sanitization: The skill includes basic integrity checks (CRC validation) and stops if damaged entries are encountered.
