Could you build this?
Partial The basic CLI and multi-agent coordination loop can be vibe-coded, but robust autonomous code editing, codebase indexing, and test verification across large repositories require deep agentic harness infrastructure.
What it would actually take: The stack comprises a CLI runner (Rust/Go/Node), AST-based code indexing (tree-sitter), background test runner sandboxing (Docker/eBPF/Wasm), and an agent orchestration state machine. The difficult challenge is handling context window management, precise AST-guided file patching, and deterministic multi-step rollback and error-recovery mechanisms across varied codebases.
