Robot Assisted Code Review: Why Deep Reasoning Just Killed the Manual Code Walk
In a very weird but real way, modern extended-reasoning LLMs do for software engineering overall what Rust did for memory and resource management. Rust didn’t invent the discipline required to prevent double-frees or data races; it simply codified the rigorous mental accounting that C and C++ systems programmers had to maintain in their heads, turning a fragile mental model into deterministic compiler enforcement. What an LLM running on extended reasoning mode does is act as a semantic borrow checker for distributed application logic. The Semantic Borrow Checker By executing exhaustive control flow checks, tracing object conformance through deep multi-layer call chains, and pressure-testing failure modes, an immense number of bugs, silent race conditions, and architectural flaws are surfaced well before code touches a runtime environment. The manual "code walk" or "desk check" has historically been the most effective, battle-tested practice in a vete...
