The Agent Skills Directory

[Command Execution] (HIGH): The skill instructs the agent to execute the shell command date +%Y%m%dT%H%M%S and perform file writing operations to a specific path. While the specific command is common, the integration of these capabilities with untrusted input is dangerous.
[Indirect Prompt Injection] (HIGH): The skill exhibits high-risk vulnerability surface patterns:
Ingestion points: The user-provided concept ({概念名}) is directly ingested into the workflow (File: SKILL.md).
Boundary markers: There are no delimiters or instructions provided to the agent to treat the user input as data rather than potential code/commands.
Capability inventory: The skill possesses the capability to run subprocesses (shell commands) and write files to the user's home directory (~/Documents/notes/).
Sanitization: There is no evidence of sanitization or validation of the user input before it is used to construct a filename or shell command context.
Risk: A malicious user could provide an input such as ; rm -rf ~ ; as the 'concept', which might be executed or cause destructive file operations depending on the agent's tool implementation.
[Dynamic Execution] (MEDIUM): The skill dynamically constructs a file path and a shell command string at runtime based on user input, which is a prerequisite for injection attacks.
