The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes lettabot-cron and lettabot-message command-line utilities. These tools are recognized as legitimate vendor resources originating from the author 'letta-ai'.
[PROMPT_INJECTION]: The skill establishes a scheduling mechanism where predefined messages are processed by the agent at set times. Although this creates a surface for indirect prompt injection, the skill employs structured message headers (e.g., [cron:ID Name]) and provides the agent with explicit context (current time, job metadata), which serves as a boundary marker to help the agent distinguish automated tasks from direct user instructions.
