--------------------------------

### Python Script for File Path Validation

Source: https://github.com/wirasm/prps-agentic-eng/blob/development/PRPs/ai_docs/hooks.md

A Python script embedded within a command that reads JSON input from stdin. It extracts the 'file_path' from the 'tool_input' object and checks if it contains any of the specified sensitive file patterns. It returns an exit code of 2 if sensitive, and 0 otherwise.

```python
import json, sys
data=json.load(sys.stdin)
path=data.get('tool_input',{}).get('file_path','')
sys.exit(2 if any(p in path for p in ['.env', 'package-lock.json', '.git/']) else 0)
```

--------------------------------

### Make a Code Change with Claude Code

Source: https://github.com/wirasm/prps-agentic-eng/blob/development/PRPs/ai_docs/getting_started.md

A prompt to instruct Claude Code to add a 'hello world' function to a main file. Claude will find the file, propose changes, seek approval, and then make the edit.

```text
> add a hello world function to the main file
```

--------------------------------

### Install Claude Code (Native Installer)

Source: https://github.com/wirasm/prps-agentic-eng/blob/development/PRPs/ai_docs/cc_deployment.md

Installs the stable, latest, or a specific version of Claude Code using a native installer script. This method is recommended for macOS, Linux, WSL, and Windows PowerShell.

```bash
# Install stable version (default)
curl -fsSL https://claude.ai/install.sh | bash

# Install latest version
curl -fsSL https://claude.ai/install.sh | bash -s latest

# Install specific version number
curl -fsSL https://claude.ai/install.sh | bash -s 1.0.58
```

```powershell
# Install stable version (default)

--------------------------------

### File Protection Hook Configuration

Source: https://github.com/wirasm/prps-agentic-eng/blob/development/PRPs/ai_docs/hooks.md

This JSON configuration defines a 'PreToolUse' hook that intercepts 'Edit', 'MultiEdit', or 'Write' commands. It executes a Python script to check if the target file path contains sensitive indicators like '.env', 'package-lock.json', or '.git/'. If sensitive, it exits with code 2, otherwise 0.

```json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Edit|MultiEdit|Write",
        "hooks": [
          {
            "type": "command",
            "command": "python3 -c \"import json, sys; data=json.load(sys.stdin); path=data.get('tool_input',{}).get('file_path',''); sys.exit(2 if any(p in path for p in ['.env', 'package-lock.json', '.git/']) else 0)\""
