IDEcline: How the world's most powerful coding tools became second-class citizens overnight

Abstraction: Three-wave shift from IDE-centric to agent-control-plane software development

Key points:

• Three waves: Wave 1 — AI as IDE plugin (GitHub Copilot); Wave 2 — CLI agents doing work in the terminal (Claude Code, Gemini CLI); Wave 3 — desktop control planes orchestrating multi-agent, long-running, parallel tasks
• Agent control plane coordinates five things: tasks, tools, permissions, context, and review — functions that exceed what IDE-first workflows can deliver
• Anthropic's Claude Cowork and OpenAI's Codex macOS app represent Wave 3: desktop environments where agents read/modify files, run commands, and execute in sandboxes outside the IDE
• IDEs become high-trust verification surfaces (diff review, debugging edge cases) rather than the orchestration layer; JetBrains, Microsoft, and Apple face strategic pressure to integrate or lose relevance
• Apple integrated OpenAI Codex and Anthropic agents into Xcode, showing incumbent IDEs will fight to recapture orchestration; competitive outcome depends on where trust/auditing lands
