xHR Allocation Management

1. Call the bundled xhr-assistant MCP server's read tool with skills/allocation_management/SKILL.md.
2. Follow only child entrypoints declared by that index.
3. Call that same MCP server's read tool for the single leaf that best matches the request.
4. Follow the complete leaf instructions and collect all required arguments.
5. Call that same MCP server's exec tool only for a script explicitly declared by the leaf.
6. If exec returns AUTHENTICATION_REQUIRED, ask for explicit confirmation to open the private xHR authentication window. After confirmation, call authenticate with no arguments, then retry the original exec once when authentication succeeds.
7. Never ask for or accept an access token in chat or MCP tool arguments.
8. Never guess a script path, operation, identifier, or argument.
9. Obtain explicit confirmation before an action that changes xHR data.
