Could you build this?
Partial A basic CLI AI agent can be vibe-coded, but an ultra-low-memory, multi-agent terminal harness written in high-performance Rust with robust local semantic memory and swarm orchestration requires solid systems programming.
What it would actually take: The architecture requires a native Rust binary integrating terminal UI libraries (e.g., Ratatui), an async runtime (Tokio), and low-level pty process spawning for command execution. Key components include local vector storage / SQLite with optimized embeddings, file-watching event loops, AST parsing (Tree-sitter) for differential code edits, and an IPC protocol for coordinating parallel agent swarms. The primary challenge is maintaining negligible RAM and CPU overhead while managing complex LLM tool-calling loops and terminal states.

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