When & Why to Use This Skill

The Shared Setup Patterns skill is a foundational utility designed to standardize and secure project initialization for Claude agents. It provides a centralized repository of configuration templates, security guardrails, and framework detection logic. By implementing pre-tool and post-tool hooks, it prevents dangerous command execution while ensuring code quality through automated formatting. This skill optimizes agent performance by reducing token consumption and establishing a consistent '.claude' directory structure for superior project memory management.

Use Cases

  • Security Guardrails: Automatically block high-risk terminal commands like 'rm -rf' or 'sudo' and validate JSON/Markdown outputs to ensure system safety and data integrity.
  • Automated Project Structuring: Initialize new repositories with a standardized .claude/ directory, including memory templates for tracking dependencies, architectural decisions, and coding conventions.
  • Intelligent Framework Detection: Rapidly identify programming languages (Python, Go, Rust) and frameworks (FastAPI, Next.js, React) in existing codebases to provide context-aware development assistance.
  • Automated Code Quality Control: Trigger linters and formatters like Ruff, Prettier, or ESLint immediately after code generation to maintain consistent styling and catch syntax errors early.
  • Token Efficiency Optimization: Reuse shared configuration patterns across multiple setup commands to save significant context window space and improve agent response speed.

Shared Setup Patterns

Purpose: Common configuration patterns and templates shared across all project setup commands.

Used by: /setup:python, /setup:javascript, /setup:existing, /setup:explore, /setup:user

Token Impact: Provides ~1,700 tokens of shared templates loaded once, avoiding duplication across 5+ commands (saves ~3,200 tokens through reuse).

Contents

This skill contains ONLY patterns shared by multiple setup commands:

  1. Security Hooks - PreToolUse and PostToolUse hooks for all project types
  2. Claude Framework Structure - .claude/ directory templates and memory files
  3. Framework Detection - Patterns for auto-detecting project languages and frameworks

Language-specific templates (Python, JavaScript, etc.) are kept inline in their respective commands.

1. Security Hooks

Located: templates/security_hooks.json

Comprehensive security and quality hooks configuration:

  • PreToolUse: Blocks dangerous commands (rm -rf, sudo, chmod 777)
  • PostToolUse: Auto-formats code (ruff, prettier, eslint), validates JSON/markdown

Used by: ALL setup commands that create projects

2. Claude Framework Structure

Located: templates/claude_framework/

Templates for .claude/ directory structure:

  • structure.md - Directory layout and purpose
  • memory_templates/ - project_state.md, dependencies.md, conventions.md, decisions.md
  • work_structure.md - Work directory organization

Used by: ALL setup commands

3. Framework Detection Patterns

Located: templates/framework_detection.md

Patterns for auto-detecting:

  • Languages: Python, JavaScript/TypeScript, Go, Rust
  • Frameworks: FastAPI, Django, Flask, Next.js, React, Express
  • Tools: pytest, Jest, Mocha, go test, cargo test

Used by: /setup:existing, /setup (if dispatcher exists)

Usage Pattern

Commands reference this skill in frontmatter:

skills: [shared-setup-patterns]

Then access specific templates:

  • Security hooks: Load from templates/security_hooks.json
  • Framework structure: Generate from templates/claude_framework/ templates
  • Detection: Use patterns from templates/framework_detection.md

Design Principle

Only truly shared content lives here. Language-specific templates (Python pyproject.toml, JavaScript package.json) stay inline in their respective commands to avoid skill overhead for single-use templates.

This keeps each command self-contained while sharing common infrastructure patterns.
