3description: Shared configuration patterns for project setup commands. Provides security hooks, Claude framework structure templates, and framework detection patterns used across multiple setup commands.

6# Shared Setup Patterns
7 
8**Purpose**: Common configuration patterns and templates shared across all project setup commands.
9 
10**Used by**: `/setup:python`, `/setup:javascript`, `/setup:existing`, `/setup:explore`, `/setup:user`
11 
12**Token Impact**: Provides ~1,700 tokens of shared templates loaded once, avoiding duplication across 5+ commands (saves ~3,200 tokens through reuse).

16## Contents
17 
18This skill contains ONLY patterns shared by multiple setup commands:
19 
201. **Security Hooks** - PreToolUse and PostToolUse hooks for all project types
212. **Claude Framework Structure** - .claude/ directory templates and memory files
223. **Framework Detection** - Patterns for auto-detecting project languages and frameworks
23 
24Language-specific templates (Python, JavaScript, etc.) are kept inline in their respective commands.

28## 1. Security Hooks
29 
30Located: `templates/security_hooks.json`
31 
32Comprehensive security and quality hooks configuration:
33- **PreToolUse**: Blocks dangerous commands (rm -rf, sudo, chmod 777)
34- **PostToolUse**: Auto-formats code (ruff, prettier, eslint), validates JSON/markdown
35 
36Used by: ALL setup commands that create projects
37

40## 2. Claude Framework Structure
41 
42Located: `templates/claude_framework/`
43 
44Templates for .claude/ directory structure:
45- `structure.md` - Directory layout and purpose
46- `memory_templates/` - project_state.md, dependencies.md, conventions.md, decisions.md
47- `work_structure.md` - Work directory organization
48 
49Used by: ALL setup commands
50 
51---
52 
53## 3. Framework Detection Patterns
54 
55Located: `templates/framework_detection.md`
56 
57Patterns for auto-detecting:
58- Languages: Python, JavaScript/TypeScript, Go, Rust
59- Frameworks: FastAPI, Django, Flask, Next.js, React, Express
60- Tools: pytest, Jest, Mocha, go test, cargo test
61 
62Used by: `/setup:existing`, `/setup` (if dispatcher exists)
63

66## Usage Pattern
67 
68Commands reference this skill in frontmatter:
69```yaml
70skills: [shared-setup-patterns]
71```
72 
73Then access specific templates:
74- Security hooks: Load from `templates/security_hooks.json`
75- Framework structure: Generate from `templates/claude_framework/` templates
76- Detection: Use patterns from `templates/framework_detection.md`
77

80## Design Principle
81 
82**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.
83 
84This keeps each command self-contained while sharing common infrastructure patterns.
