The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions and automation for downloading and installing software from external sources using npx and go install.
The npx -y @mvanhorn/printing-press-library install ucp --cli-only command downloads and executes code from the npm registry.
The go install commands fetch and compile source code from github.com/mvanhorn/printing-press-library.
[COMMAND_EXECUTION]: The skill relies on the Bash tool to execute the ucp-pp-cli binary and manage MCP server registration via claude mcp add.
[DATA_EXFILTRATION]: The CLI includes a --deliver webhook:<url> flag that allows the agent to POST command results directly to an external URL. This provides a direct capability for exfiltrating processed commerce data or sensitive command outputs to untrusted endpoints.
