Annotation Format Converter

Security checks for vulnerabilities and agentic risk

Overview

This is a normal local annotation-conversion skill, but one confirmed path-handling bug can let a crafted COCO file overwrite writable .txt files outside the chosen output folder.

Review before installing or running on annotation files from other people. The converter should be hardened to reject absolute paths and parent-directory components in COCO file_name fields, verify outputs remain inside the chosen output folder, and avoid overwriting existing files unless explicitly requested.
