The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill connects to the well-known Twilio API at api.twilio.com to send messages. Communication with this trusted service is necessary for the skill's primary function and follows standard integration practices.
[COMMAND_EXECUTION]: The skill executes a local shell script (scripts/run.sh) and provides curl command examples to interface with the Twilio API.
[PROMPT_INJECTION]: The skill presents an indirect prompt injection surface as it processes external content for delivery via SMS.
Ingestion points: User-provided content is accepted through the message_body and to_phone parameters.
Boundary markers: No explicit delimiters are present in the instruction template to isolate user input from the skill logic.
Capability inventory: The skill uses curl to perform authenticated network POST requests and executes a bundled bash script.
Sanitization: The implementation uses curl's --data-urlencode flag, which ensures that user-provided message content is properly escaped before being sent to the external API.
