Claude Code Kit: Reliable Coding Using Claude Skills, Hooks and Command (github.com)

Anthropic-tooling developer blencorp released Claude Code Kit — a one-command (npx github:blencorp/claude-code-kit) installer that auto-detects your stack (Next.js, React, Prisma, Express, Tailwind, shadcn, TanStack, etc.), copies a framework-specific kit into .claude/, and wires up skills, hooks, agents and slash-commands so relevant Claude skills auto-activate based on prompts, file edits, and project structure. The installer runs in under 30 seconds, generates a skill-rules.json with prompt, intent (regex), file-path and content-pattern triggers, and provides core hooks like skill-activation-prompt (suggests relevant skills) and post-tool-use-tracker (tracks file changes). Prebuilt slash commands (/build-and-fix, /code-review, /dev-docs, /test-route) and specialized assistants (refactor-planner, code-architecture-reviewer, web-research-specialist) are included to automate common dev workflows. For AI/ML practitioners and developer-tooling teams this reduces friction: skills no longer sit idle—you get context-aware code guidance without memorizing skill names. Detection uses package.json/config/file tests and kits are extensible (kit.json metadata, SKILL.md <500 lines, YAML frontmatter, resources folder). Optional agents include TypeScript checks, build-error resolvers and enhanced build filtering (monorepo-friendly). The project is MIT-licensed and accepts community kits, so teams can author detectors, triggers and domain-specific skills to scale Claude expertise across fullstack repositories — making Claude-driven code assistance more reliable and integrated into real-world developer workflows.
