    "why": "Spec Kit gives your coding agent structured context instead of ad-hoc prompts, keeping intent and evidence ahead of implementation. It pins one order — constitution → specify → plan → tasks → implement → converge — as /speckit-* skills inside the agent's chat and leaves each step behind as a document. It is GitHub's own MIT toolkit: the repository opened in August 2025 and v1.0.6 shipped on 2026-09-10.",
    "take": "If your agent's output swings every run, GitHub's answer is to fix the documents you feed it before the code.",
    "build": [
      "A Python terminal tool, specify-cli, installed with uv; `specify init` writes the command files and the `.specify/` directory layout for the agent you pick. Three processes are independent entry points: Spec-Driven Development ships in core, while bug fixing (`specify extension add bug` → assess → fix → test) and idea assessment (`specify extension add assess` → intake → research → define → shape → decide) are bundled extensions you add when needed. Extensions, presets, workflows and bundles reshape the process, organisations can host their own catalogs, and the official docs list 38 agent integrations — Copilot, Claude Code, Codex, Gemini, Cursor, Zed and others — selected by one integration key."

    "caveat": [
      "MIT licence — commercial use, modification and redistribution allowed. Spec Kit itself is free, but no coding agent is included; you bring your own (README prerequisite) and that agent writes the actual code. It is a terminal tool that needs Python 3.11+ and uv installed first, and the /speckit-* steps are skills invoked in the agent's chat, not shell commands — spelling differs by agent (/speckit-…, $speckit-…, /skill:speckit-…). The official page states Windows, macOS and Linux support and operation offline and behind firewalls. Examples default to GitHub Copilot, so other agents need one look at the integrations reference. Currently v1.0.6 (2026-09-10), a stable release; the 1.0 line is recent, so check the Upgrade guide when commands or layout change between releases."
