The cross-vendor patterns and craft that make any coding agent — Claude Code, Codex, Gemini — produce reliable, mergeable output

A 2026 survey of every major AI coding agent — Claude Code, OpenAI Codex, Gemini CLI, GitHub Copilot, Cursor — with side-by-side comparison and decision frame for picking your stack.

Most enterprise engineering is brownfield. Agents finally made it tractable: comprehension, safety nets, strangler slices, and migrations, practiced on a provided legacy codebase, applied to yours.

Master Google's agentic dev platform — the Antigravity desktop app, the agy CLI and SDK, migration from Gemini CLI, and the enterprise + cost tradeoffs
