We noticed a counterintuitive trend: veteran developers used to graphical AI coding assistants like Cursor are now migrating back to the command line in droves. Terminal AI agents—Claude-Code, AGY, Codex, programs that autonomously execute multi-step coding tasks inside the terminal—are becoming the new favorites. But after reading this 10,000-word breakdown on Juejin, our judgment is clear: this is not "one replacing the other." AI coding tools have officially split into two routes—CLI runs long-chain automation, IDE holds the line on visual review and debugging, and mixing both is the new normal for top teams.

What This Is

The essence of this route war is the split between two mental models: human-centered versus AI-centered.The IDE camp (Cursor, Windsurf): AI is your "copilot" sitting on the right side, generating code and waiting for you to click Accept. The upside is WYSIWYG—breakpoint debugging, pixel-level UI tuning, and line-by-line review of complex Diffs all rely on the graphical interface.The CLI camp (Claude-Code, AGY, Codex): AI is treated as an independent Unix process that can autonomously run tests, read error logs, rewrite code, loop until green, and auto-commit. Throughout the process, you just set the goal—you don't need to confirm line by line.One line: one hands you tools while you write code, the other acts as project lead, completing an entire sequence of actions for you.

Industry View

Three hardcore advantages backing the CLI camp:First, scriptable. Terminal AI can be embedded in Shell scripts and cron jobs, achieving "automated nightly 2 AM dependency scans across 30 repos"—the IDE can't.Second, self-healing error loops. Code missing a dependency? Inside the terminal, the AI directly calls the compiler, reads the Exit Code, inspects the error stack, and retries on the spot. No copy-paste "context breaks."Third, almost no resource drain. CLI tools are light enough to run on remote servers in the background—your local fan won't spin up.But the opposition is equally sharp. The author explicitly warns, "no sane engineer will hand over full merge rights on core payment infrastructure to the CLI." The red-green split-screen Diff review is the last visual safety valve guarding system baselines—terminal character streams simply cannot substitute.The deeper risk: the CLI route assumes fluency in Linux, pipe operators (|), and Shell scripts, and that threshold locks out 90% of ordinary developers. This isn't just a tool debate—it's a re-stratification of the engineering profession.

Impact on Regular People

For enterprise IT: when procuring AI coding tools in the future, "IDE or CLI" will be a false question—the more likely budget structure is running both simultaneously, dispatched by scenario.For individual careers: the core value of programmers is shifting from "writing code fast" to "understanding what AI is doing and gatekeeping at critical junctures." Those who can only hit Accept will be the first to be eliminated.For the consumer market: this doesn't directly affect end users, but it indirectly shapes the iteration speed and stability of all software—the more autonomous AI becomes, the more critical human review becomes.
