The Agent Skills Directory

Boundary markers: There are no delimiters or explicit instructions provided to the agent to prevent it from obeying instructions embedded within the processed text. Capability inventory: The skill executes a local binary that has network and file read capabilities. Sanitization: There is no evidence of content sanitization or validation before the extracted text is returned to the agent context.
