Implementation Reference
- Core logic that retrieves the target element by path and constructs context with preceding and following sibling elements.
def get_context(self, path: str) -> Dict[str, Any]: """Get element and its neighbors""" target = self.find_by_path(path) if not target: return {"error": "Not found"} siblings = target.parent.children if target.parent else self.elements idx = siblings.index(target) context = { "current": {"path": target.path, "content": target.content}, "before": None, "after": None, } if idx > 0: context["before"] = { "path": siblings[idx - 1].path, "content": siblings[idx - 1].content[:200], } if idx < len(siblings) - 1: context["after"] = { "path": siblings[idx + 1].path, "content": siblings[idx + 1].content[:200], } return context - EditTool instance method that caches/loads the Document and calls its get_context method.
