The Agent Skills Directory

Bash Tool Integration: The skill utilizes standard Unix utilities such as awk, cut, and sort to perform local data transformations. These tools are used within their intended scope for text and record processing.
Indirect Prompt Injection Surface: The skill processes data from external CSV files, which presents a surface for potential indirect prompt injection where content in a file might attempt to influence an AI agent.
Ingestion points: Data is ingested through the $FILE argument in analyze.sh, filter.sh, select.sh, and sort.sh.
Boundary markers: The scripts do not implement specific delimiters or 'ignore' instructions to isolate CSV data from the agent's context.
Capability inventory: The skill's capabilities are limited to reading and processing files; it lacks network access or file-writing permissions.
Sanitization: The implementation uses shell variable quoting and awk's -v variable passing to handle inputs, which helps mitigate basic shell injection risks.
Secure Scripting Practices: The scripts are written with standard security considerations for shell environments. For instance, file paths are quoted to handle special characters correctly, and command-line flags in the sorting script are explicitly validated through a case statement.
