The Agent Skills Directory

[COMMAND_EXECUTION]: The skill instructs the agent to use the grep command with user-supplied $ARGUMENTS. If the platform does not sanitize these arguments before execution, an attacker could inject shell metacharacters (e.g., ;, |, `) to execute arbitrary commands on the host system.
[INDIRECT_PROMPT_INJECTION]: The skill relies on untrusted external data in .understand-anything/knowledge-graph.json to guide its actions.
Ingestion points: The skill reads .understand-anything/knowledge-graph.json (Steps 1-5) to identify node IDs and file paths.
Boundary markers: None. There are no instructions to the agent to treat the content of the JSON as untrusted or to ignore embedded instructions/malicious paths.
Capability inventory: The agent has the capability to read arbitrary files (Step 6) based on the filePath extracted from the JSON. A malicious JSON could facilitate data exposure by pointing to sensitive files like ~/.ssh/id_rsa or /etc/passwd.
Sanitization: None. The skill assumes the filePath values and node metadata are legitimate and safe to process.
