exploring-mcp-sessions
Investigate individual PostHog MCP sessions — the sequence of tool calls a single agent made in one run, what it was trying to do, and where it went wrong. Use when the user asks "what did this MCP session do?", "show me the tool calls for session X", "what was the agent's goal?", "which sessions had errors?", "who is connecting to my MCP?", or pastes an MCP analytics sessions URL.

W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
This skill’s runtime workflow reads `$mcp_*` fields (including `intent`, `tool_name`, and `error_message`) from `posthog:mcp-analytics-sessions-list`, `posthog:mcp-analytics-sessions-tool-calls`, and `posthog:mcp-analytics-sessions-generate-intent`, which are derived from outsider-authored MCP client/tool call text/events rather than user-authored content.
