xHR Documents

1. Call the bundled xhr-assistant MCP server's read tool with skills/documents/SKILL.md.
2. Follow only child entrypoints declared by that index.
3. Call that same MCP server's read tool for the selected leaf and follow its complete instructions.
4. Call that same MCP server's exec tool only when the leaf explicitly declares a script.
5. If exec returns AUTHENTICATION_REQUIRED, ask for explicit confirmation, call authenticate with no arguments, and retry the original exec once after success.
6. Never request or accept an access token in chat or tool arguments.
7. Respect document access controls and do not infer inaccessible content.
8. Obtain explicit confirmation before an action that changes xHR data.
