+## 📖 Overview
+
+Croto is a specialized branch of [ChatDev](https://github.com/OpenBMB/ChatDev) that orchestrates multiple agent teams to jointly propose diverse task-oriented solutions and collaborate through strategic cross-team interactions at key phases. It enables teams to maintain their independence while leveraging collective insights for superior solution generation. The methods used in Croto—including greedy aggregation, hierarchy partitioning, and pruning strategy—are well integrated into MacNet codebase, specifically in `chatdev.waiting` and the aggregation function in `graph.py`.
+
+```python
+def aggregate(self, prompt: str, retry_limit: int, unit_num: int, layer_directory: str, graph_depth: int,
+               store_dir: str) -> int:
+     """Aggregate solutions from predecessors."""
+     logging.info(f"Node {self.id} is aggregating with {len(self.pre_solutions)} solutions")
+
+     with open("config.yaml", "r", encoding="utf-8") as f:
+         cc_prompt = "\n\n".join(yaml.load(f.read(), Loader=yaml.FullLoader).get("Agent").get("cc_prompt"))
+         cc_prompt = self.system_message + cc_prompt
+
+     for file in self.pre_solutions:
+         with open(layer_directory + "/solution_{}.txt".format(file), "w") as f:
+             for key in self.pre_solutions[file].codebooks.keys():
+                 f.write(str(key) + '\n\n' + self.pre_solutions[file].codebooks[key] + '\n\n')
+
+     self.pool = Pool(len(self.pre_solutions), unit_num, layer_directory, self.model)
+     for i in range(retry_limit):
+         new_codes = self.pool.state_pool_add(layer_directory, cc_prompt, 6000000, prompt,
+                                              Codes(),
+                                              store_dir,
+                                              temperature=1 - self.depth / graph_depth,
+                                              )
+         if new_codes is None:
+             logging.info(f"Retry Aggregation at round {i}!")
+         else:
+             self.solution = new_codes
+             logging.info(f"Node {self.id} has finished aggregation!")
+             return 0
+     print(f"ERROR: Node {self.id} has reached the retry limit!\n")
+     return 1
+```
