The Agent Skills Directory

[Indirect Prompt Injection] (HIGH): The skill possesses a high-risk capability tier due to the combination of processing untrusted external content and having write access to the file system.
Ingestion points: scripts/json_yaml_converter.py:load_file (line 46) reads content from user-specified or agent-specified file paths.
Boundary markers: Absent. The skill parses raw content into data structures without employing delimiters or instructions to the agent to ignore embedded natural language commands.
Capability inventory: scripts/json_yaml_converter.py:save_file (line 64) performs Path.write_text operations, and validate_file (line 103) returns data summaries to the agent context.
Sanitization: The script uses yaml.safe_load() (line 55), which is an excellent defense against YAML-based Remote Code Execution (RCE). However, it does not sanitize the resulting data for natural language instructions that could influence the agent's logic.
[Metadata Poisoning] (LOW): The source.repository in SKILL.md points to the pyyaml library repository rather than the skill's own source, which is misleading metadata.
[Unverifiable Dependencies] (LOW): The script requires pyyaml and toml. While these are trusted, well-known packages, the skill does not specify or pin versions, which is a minor best-practice violation.
