The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill installs the wikipedia-pp-cli tool using npx (from the @mvanhorn/printing-press package) and go install (from github.com/mvanhorn/printing-press-library). These are vendor-owned resources used for the skill's primary function.
[COMMAND_EXECUTION]: The skill executes the wikipedia-pp-cli binary to fetch Wikipedia data. It includes a documented --deliver flag that allows the agent to route output to the terminal, local files, or external webhooks.
[DATA_EXFILTRATION]: The --deliver webhook:<url> flag enables sending tool output to external URLs. While this involves network operations to non-whitelisted domains, it is a transparent, functional feature of the CLI used for data export and integration.
[PROMPT_INJECTION]: The skill ingests article content from Wikipedia, which is an external user-editable source. This constitutes an indirect prompt injection surface.
Ingestion points: Article summaries and HTML content are retrieved from Wikipedia via the page get-summary and page get-html commands.
Boundary markers: No specific delimiters or boundary markers are instructed for use when the agent processes the retrieved Wikipedia content.
Capability inventory: The skill has the capability to write to the filesystem and perform network POST requests through the CLI's delivery parameters.
Sanitization: The instructions do not specify any sanitization or filtering of the Wikipedia content before it is processed by the agent.
