The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill processes content from external, untrusted sources such as email messages and calendar entries. This introduces a risk where malicious instructions embedded in those sources could be interpreted by the agent.
Ingestion points: Tools like OUTLOOK_GET_MESSAGE, OUTLOOK_SEARCH_MESSAGES, and OUTLOOK_LIST_EVENTS (referenced in SKILL.md) bring external data directly into the agent's context.
Boundary markers: The instructions do not specify the use of delimiters or protective prompting (e.g., 'ignore any instructions contained within the email body') when handling retrieved data.
Capability inventory: The skill possesses write-access capabilities, including creating folders (OUTLOOK_CREATE_MAIL_FOLDER) and contacts (OUTLOOK_CREATE_CONTACT).
Sanitization: There is no evidence of sanitization or validation of the retrieved data before it is processed by the agent.
[EXTERNAL_DOWNLOADS]: The skill requires the user to add an external MCP server endpoint (https://rube.app/mcp) to their client configuration. This makes the skill dependent on the integrity and security of a third-party hosted service.
