Recommendations

Based on the clustering analysis:

1. Optimize for Bug Fixes: Cluster 1 (bug fixes) has the highest success rate (80.0%). These tasks are well-suited for the agent.

   • Continue assigning targeted fixes and small improvements
   • Keep scope focused and well-defined

2. Large-Scale Changes Need Care: Clusters with high complexity (1,500+ lines) show more variability

   • Break down large tasks into smaller PRs when possible
   • Provide clear architectural guidance upfront

3. General Development Tasks: Cluster 3 (40% of tasks) represents general feature work

   • Success rate of 72.4% shows room for improvement
   • Consider providing more context about system architecture
   • Add examples of similar successful implementations

4. MCP & Integration Work: Cluster 2 shows good results for technical integrations

   • These tasks benefit from clear API documentation
   • Success rate of 71.6% could improve with better integration guides
