The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill documentation provides instructions to download and install executable code from external registries.
Uses npx to install the @mvanhorn/printing-press package from the NPM registry.
Uses go install to download and compile the archive-is-pp-cli tool directly from a GitHub repository.
[COMMAND_EXECUTION]: The skill is built around the execution of a local binary (archive-is-pp-cli) to perform web archival and retrieval operations.
[DATA_EXFILTRATION]: The CLI includes a --deliver flag that allows the agent to route the output of its operations to arbitrary external webhooks or local file paths.
This feature enables the transfer of retrieved article text or metadata to third-party network endpoints, which could be misused to exfiltrate data if a malicious destination is provided.
[PROMPT_INJECTION]: The skill ingests and processes data from external sources, creating a risk of indirect prompt injection.
Ingestion points: The tool fetches article text and HTML from third-party archive backends (archive.today and the Wayback Machine) based on user-provided URLs.
Boundary markers: There are no explicit instructions or delimiters used to prevent the agent from following instructions that might be embedded in the archived content.
Capability inventory: The agent has the ability to write to the local file system and perform network requests via the CLI's --deliver and feedback features.
Sanitization: The skill does not describe any sanitization or filtering of the fetched content before it is processed by the agent.
