Claude Code Kit

Claude Code infrastructure with auto-activating skills and framework-specific kits.

Install complete Claude Code infrastructure in 30 seconds with automatic framework detection and skill auto-activation.

Quick Start

npx github:blencorp/claude-code-kit

What happens:

1. Detects your frameworks (Next.js, React, Express, Prisma, etc.)
2. Asks which kits to install
3. Copies hooks, agents, commands, and skills to .claude/
4. Configures automatic skill activation via skill-rules.json
5. Installs everything in < 30 seconds

Result: Skills automatically activate when you need them based on your prompts, file edits, and technology usage.

What's a Kit?

A kit is a framework-specific package that includes:

• Skill - Best practices, patterns, and examples for the framework
• Auto-activation triggers - Keywords and patterns that activate the skill
• Resources - Detailed guides organized by topic
• Detection logic - Automatic framework detection

When installed, kits make Claude Code an expert in your stack.

Core Infrastructure

Every installation includes:

Hooks (6)

Essential (Auto-configured):

• skill-activation-prompt (UserPromptSubmit) - Analyzes prompts and suggests relevant skills automatically
• post-tool-use-tracker (PostToolUse) - Tracks file changes to maintain context across sessions

Optional (Requires customization):

• tsc-check (Stop) - TypeScript compilation check (monorepo-friendly)
• trigger-build-resolver (Stop) - Auto-launches build-error-resolver agent on build failures
• error-handling-reminder (Stop) - Gentle reminders for error handling patterns
• stop-build-check-enhanced (Stop) - Enhanced build checking with smart filtering

Agents (6)

Specialized assistants for complex tasks:

• code-architecture-reviewer - Reviews code for adherence to best practices and architectural consistency
• code-refactor-master - Refactors code for better organization, cleaner architecture, improved maintainability
• documentation-architect - Creates comprehensive documentation from code and memory
• plan-reviewer - Reviews development plans for completeness and potential issues
• refactor-planner - Analyzes code structure and creates comprehensive refactoring plans
• web-research-specialist - Researches technical solutions across GitHub, Stack Overflow, Reddit, forums

Commands (6)

Slash commands for common workflows:

• /build-and-fix - Builds project and automatically fixes errors
• /code-review - Conducts comprehensive code review with best practices
• /dev-docs - Creates strategic development plans with structured task breakdown
• /dev-docs-update - Updates development documentation before context compaction
• /route-research-for-testing - Maps edited routes and launches comprehensive tests
• /test-route - Tests authenticated API routes with proper auth context

Skills (1)

• skill-developer - Meta-skill for creating and managing Claude Code skills following Anthropic best practices

How It Works

Auto-Activation System

Skills automatically activate based on:

1. Prompt Keywords

   • Example: "create a table component" → shadcn skill activates
   • Example: "query the database" → Prisma skill activates

2. Intent Patterns (Regex)

   • Example: "add.*authentication" → relevant auth patterns activate
   • Example: "optimize.*component" → React performance skill activates

3. File Path Triggers

   • Editing app/**/*.tsx → Next.js skill activates
   • Editing prisma/schema.prisma → Prisma skill activates

4. Content Patterns

   • File contains useQuery( → TanStack Query skill activates
   • File contains createFileRoute → TanStack Router skill activates

All configured in .claude/skills/skill-rules.json (auto-generated during install).

Usage Examples

Installing for Next.js + shadcn Project

cd my-nextjs-app
npx github:blencorp/claude-code-kit

Detects:

• Next.js (from package.json)
• React (from package.json)
• shadcn/ui (from components.json)
• Tailwind CSS (from tailwind.config.ts)

Prompts: "Install these detected kits? (Y/n)"

Result: Next.js, React, shadcn, and Tailwind skills auto-activate when you:

• Ask: "create a server component with a data table"
• Edit: app/dashboard/page.tsx
• Mention: "use shadcn table component"

---

Installing for Express Backend

cd my-api
npx github:blencorp/claude-code-kit

Detects:

• Express (from package.json)
• Node.js (module type)
• Prisma (from prisma/schema.prisma)

Prompts: "Install these detected kits? (Y/n)"

Result: Express, Node.js, and Prisma skills auto-activate when you:

• Ask: "create an API route for users"
• Edit: routes/users.ts
• Mention: "query users from database"

---

Installing for Full-Stack App

cd my-fullstack-app
npx github:blencorp/claude-code-kit

Detects both frontend and backend kits automatically

Prompts: Select from detected frameworks

Result: Complete coverage of your entire stack

kit.json Format

{
  "name": "your-framework",
  "displayName": "Your Framework",
  "description": "Short description of what this kit provides",
  "detect": "command to detect framework",
  "provides": ["skill:your-framework"]
}

Detection Examples:

# Detect from package.json
"detect": "grep -q '\"your-framework\"' package.json"

# Detect from config file
"detect": "test -f your-framework.config.js"

# Detect from directory
"detect": "test -d src/your-framework"

SKILL.md Format

Follow Anthropic best practices:

• Keep main file < 500 lines
• Use YAML frontmatter
• Add table of contents
• Use progressive disclosure (link to resources/)
• Include complete examples
