The Agent Skills Directory

[SAFE]: The skill serves as a comprehensive educational resource and workflow guide for steganography forensics. It outlines systematic methods for detecting hidden data using established techniques such as LSB analysis, metadata inspection, and structural validation.
[EXTERNAL_DOWNLOADS]: The guide includes installation instructions for forensic utilities using standard package managers including apt, pip3, gem, and go. It also references specific tool binaries from GitHub (RickdeJager/stegseek) and the Caesum security handbook (Stegsolve.jar). These external resources are standard utilities within the security community and are consistent with the skill's forensic purpose.
[COMMAND_EXECUTION]: The skill provides numerous command-line examples for forensic analysis tools such as zsteg, binwalk, exiftool, and steghide. These commands are intended for local execution to inspect files and do not involve suspicious network exfiltration or unauthorized system access.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and analyze untrusted external media files (images, audio, and text). While these files represent an ingestion point for potentially adversarial content, the skill emphasizes the use of specialized forensic tools for data extraction rather than direct interpolation of raw data into LLM prompts. There are no boundary markers or explicit sanitization routines, but the analytical nature of the workflow provides a layer of human-in-the-loop inspection.
