The Agent Skills Directory

[COMMAND_EXECUTION]: The skill instructs the agent to execute shell commands (git log) using the <file> placeholder, which is derived directly from user-provided $ARGUMENTS. If the agent or platform does not strictly validate this input, an attacker could provide shell metacharacters (e.g., ; rm -rf /) to execute arbitrary commands on the host system.
[PROMPT_INJECTION]: The skill is vulnerable to indirect prompt injection through its primary function of reading and explaining code and git history. Malicious instructions embedded in the code being analyzed could hijack the agent's session.
Ingestion points: Source code files and git commit logs as specified in the Code Explanation and Flow Explanation sections of SKILL.md.
Boundary markers: Absent. The instructions do not direct the agent to treat the analyzed content as data only or to ignore instructions found within that data.
Capability inventory: The agent has access to the local file system and the ability to execute git log shell commands as defined in SKILL.md.
Sanitization: Absent. The skill does not define any validation or filtering for the content it processes before analysis.
