The Agent Skills Directory

[DATA_EXFILTRATION]: The skill's configuration hardcodes a specific local filesystem path (/Users/doyoonlee/ObsidianVault), which reveals the system username (doyoonlee) to the agent and potentially in its outputs.
[COMMAND_EXECUTION]: The skill performs automated file system writes to create 마크다운 (.md) documents and update a JSON registry file (references/path-registry.json).
[PROMPT_INJECTION]: The 'New Category Registration Flow' accepts storage paths directly from user input and saves them to a persistent registry. These paths are later used to construct absolute file paths for write operations. The skill lacks instructions to sanitize or validate these paths (e.g., checking for ../ sequences), creating a path traversal risk where a user or malicious content could trick the agent into writing files to sensitive system areas.
[PROMPT_INJECTION]: Indirect Prompt Injection Risk:
Ingestion points: User-provided document content and category/path definitions during the registration flow in SKILL.md.
Boundary markers: Absent. There are no delimiters or instructions to ignore instructions embedded within the text being saved to the vault.
Capability inventory: File system write access to create/modify documents and the category registry.
Sanitization: Absent. The skill does not verify that user-supplied paths remain within the defined vault root directory.
