Full Analysis
- [INDIRECT_PROMPT_INJECTION]: The skill enables the agent to ingest and process data from external Slack conversations, which may contain hidden or malicious instructions meant to influence the agent's behavior.
- Ingestion points: The skill uses
SLACK_SEARCH_MESSAGES,SLACK_FETCH_MESSAGE_THREAD_FROM_A_CONVERSATION, andSLACK_FETCH_CONVERSATION_HISTORYas described inSKILL.mdto retrieve message content. - Boundary markers: No specific delimiters or instructions to treat external message content as untrusted are present in the skill instructions.
- Capability inventory: The agent has significant capabilities to interact with the workspace, including sending and scheduling messages (
SLACK_SEND_MESSAGE,SLACK_SCHEDULE_MESSAGE) and retrieving channel information. - Sanitization: There is no mention of content filtering, escaping, or sanitization of the Slack messages before they are processed by the agent.
- [EXTERNAL_DOWNLOADS]: The setup instructions require connecting to a remote MCP server located at
https://rube.app/mcp, which is an external dependency for the skill's operation.
