Hopper - Agentic Development Environment for Mainframe/COBOL
It combines a real TN3270 terminal and an AI agent that can operate across z/OS workflows like COBOL, VSAM, and CICS.

Could you build this?
No Interacting with mainframe environments requires specialized knowledge of legacy IBM z/OS systems, TN3270 terminal emulation, and legacy protocols like CICS and VSAM that cannot be synthesized by vibe coding.
What it would actually take: Building Hopper requires implementing a custom TN3270 protocol parser handling EBCDIC encoding, terminal screen buffers, and dynamic 3270 data streams. It must bridge z/OS subsystem management (RACF security, JCL execution, CICS transactions) with modern language models trained on massive, proprietary legacy COBOL/Assembler corpora. This demands specialized mainframe systems programmers and access to mainframe hardware or specialized emulation environments.

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