The Agent Skills Directory

Prompt Injection (LOW): The skill directly interpolates the $ARGUMENTS variable into the instructions. This allows a user to provide input that could potentially override the agent's logic, such as instructing it to delete other files instead of appending to the journal.
Indirect Prompt Injection (LOW): The skill reads existing file content which may contain instructions that influence the agent's behavior.
Ingestion points: $ARGUMENTS and the output of the Read tool for the journal file.
Boundary markers: Absent. The prompt does not use delimiters (like triple backticks or XML tags) to separate instructions from untrusted data.
Capability inventory: The skill has Read, Edit, and Glob capabilities, allowing it to explore the file system and modify content.
Sanitization: Absent. There is no logic to validate the input or escape characters before processing.
