Risk Level: SAFEINDIRECT_PROMPT_INJECTION
Full Analysis
  • [INDIRECT_PROMPT_INJECTION]: The skill processes untrusted data originating from external agent tool calls, which presents an attack surface for instructions embedded in data to influence the agent.
  • Ingestion points: Untrusted data enters the agent context via posthog:query-mcp-tool-sample-intents (retrieving agent intents) and posthog:query-mcp-tool-failures (retrieving error messages from exceptions).
  • Boundary markers: The instructions do not define explicit delimiters or warnings to ignore instructions embedded within the retrieved intent or error strings.
  • Capability inventory: The skill enables high-privilege operations including arbitrary SQL execution via posthog:execute-sql and detailed tool/session analysis via various posthog:query-* tools.
  • Sanitization: There are no specific instructions for the agent to sanitize, validate, or escape the retrieved external content before using it in its reasoning or further tool calls.
