Full Analysis
  • [COMMAND_EXECUTION]: The skill utilizes the curl utility within its workflow to fetch data from an external API. While used here for transit data, the execution of shell-based networking tools allows the agent to interact with arbitrary endpoints if configured with a malicious URL.
  • [EXTERNAL_DOWNLOADS]: The skill relies on an external proxy server, with the address determined by the KSKILL_PROXY_BASE_URL environment variable. This introduces a dependency on external infrastructure that is not under the direct control of the skill or the local environment.
  • [PROMPT_INJECTION]: The skill processes and summarizes data from an external API response, creating a surface for indirect prompt injection. If the proxy or the upstream data source were compromised, it could return instructions designed to influence the agent's behavior during the summarization phase.
  • Ingestion points: External API response from the URL defined in KSKILL_PROXY_BASE_URL (SKILL.md).
  • Boundary markers: Absent from the instruction set.
  • Capability inventory: Shell command execution via curl (SKILL.md).
  • Sanitization: No explicit sanitization or validation of the API response is described before the data is summarized by the agent.
