Spec-First injects a multi-stage workflow engine into Claude Code and Codex with 43 embedded skills and 47 agents, enabling projects to transition from ad-hoc AI conversations to governed, traceable engineering processes. It establishes three-layer architecture—entry/workflow/capability—and manages project runtime assets (contexts, brainstorms, plans, reviews, solutions) through explicit command boundaries (`/spec:*` commands, `$spec-*` shortcuts), with structured output artifacts at each stage (Stage-0 through Compound) for requirement documentation, multi-agent review, and knowledge reuse across iterations. The tool runs as an npm CLI that initializes platform-specific environments (Claude Code or Codex), handles dependency checks, and persists configuration in `.claude/` directories—turning single AI interactions into reproducible, quality-gated delivery cycles.
