Discussion
6 comments analyzed.
Competitors mentioned: Claude Code, Cursor, Codex, Gemini
Concerns raised: Cross-runtime communication between different AI agents is essential but missing, Single agent with trained preferences may be better than multi-agent frameworks, Increasing model capabilities and maintenance costs threaten multi-agent tools, Not suitable for non-technical users without simplified interface
Feature requests: Online web version for non-technical users, Cross-runtime agent communication protocol, Shared memory system across multiple agent runtimes, Coordinator agent for managing large backlogs across multiple projects

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
