The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill performs network requests to https://is.gd/create.php to generate shortened URLs. This interaction targets a well-known public service and aligns with the skill's stated functionality.
[COMMAND_EXECUTION]: The skill executes a local shell script (shorten.sh) that utilizes the curl command-line tool. The script correctly handles user input by using --data-urlencode, which prevents the input from interfering with the shell command or injecting additional HTTP parameters.
[INDIRECT_PROMPT_INJECTION]: The skill accepts user-provided URLs as input for processing.
Ingestion points: User input is received as a command-line argument in shorten.sh.
Boundary markers: Not applicable as the input is passed directly to the script argument.
Capability inventory: The skill is limited to making an HTTP POST request to a single hardcoded endpoint.
Sanitization: The use of curl --data-urlencode ensures that the URL input is treated as data and cannot be used to execute arbitrary commands or modify the intended API call.
