Pattern: Spec-Driven Development Standardizes Across All Agent Environments

Multiple (GitHub, Cursor, Anthropic, OpenAI)·medium signal

Every major AI coding environment now ships a 'spec first' workflow: GitHub Spec Kit (90K stars, 30+ agent integrations), Cursor's Design Mode, Claude Code's CLAUDE.md + plan mode, and Codex's constitution files. The convergence is not coincidental — vibe coding's failure mode (correct code, wrong intent) forced the same solution everywhere. The winning pattern is: human writes intent as structured spec → agent generates plan → human approves → agent implements → verification against spec. Tools that skip the spec step are losing adoption.
