start.ps1

+# Check if we're in the right directory
+$projectRoot = "c:\Users\PRAJWAL\OneDrive\Desktop\quantresearch\QuantResearch"


The hardcoded user-specific path makes this script non-portable. Consider using a relative path or detecting the project root dynamically (e.g., using $PSScriptRoot or looking for a marker file like pyproject.toml in parent directories).

Suggested change

# Check if we're in the right directory

$projectRoot = "c:\Users\PRAJWAL\OneDrive\Desktop\quantresearch\QuantResearch"

# Determine project root dynamically, prefer directory containing pyproject.toml

$projectRoot = $PSScriptRoot

$markerFile = "pyproject.toml"

$currentDir = $PSScriptRoot

while ($currentDir -and -not (Test-Path -LiteralPath (Join-Path $currentDir $markerFile))) {

$parentDir = Split-Path -Path $currentDir -Parent

if (-not $parentDir -or $parentDir -eq $currentDir) {

break

}

$currentDir = $parentDir

}

if ($currentDir -and (Test-Path -LiteralPath (Join-Path $currentDir $markerFile))) {

$projectRoot = $currentDir

}

SETUP_COMPLETE.md

+### 1. Start Backend Server
+
+```bash
+cd "c:\Users\PRAJWAL\OneDrive\Desktop\quantresearch\QuantResearch"


The documentation contains hardcoded user-specific paths that won't work for other developers. Replace with relative paths or generic placeholders like '<PROJECT_ROOT>' throughout the documentation.

Copilot · 2026-01-16T13:53:14Z

SETUP_COMPLETE.md

+OUTPUT_DIR=output/
+
+# Finnhub API (for market data)
+FINNHUB_API_KEY=d5f5pdpr01qtf8iml9cgd5f5pdpr01qtf8iml9d0


A real API key appears to be exposed in the documentation. This should be replaced with a placeholder like 'your-finnhub-api-key-here' to prevent potential security issues.

Suggested change

FINNHUB_API_KEY=d5f5pdpr01qtf8iml9cgd5f5pdpr01qtf8iml9d0

FINNHUB_API_KEY=your-finnhub-api-key-here

SETUP_COMPLETE.md

+REDIS_URL=rediss://default:password@your-redis-host:port
+
+# JWT Configuration
+JWT_SECRET=dev_prajwal_secret_123


The example JWT_SECRET contains a potentially real development secret. Replace with a generic placeholder like 'your-secret-key-here' to prevent developers from copying insecure secrets into production.

Suggested change

JWT_SECRET=dev_prajwal_secret_123

JWT_SECRET=your-secret-key-here

Copilot · 2026-01-16T13:53:15Z

QUICK_REFERENCE.md

+
+### Start Backend
+```bash
+cd "c:\Users\PRAJWAL\OneDrive\Desktop\quantresearch\QuantResearch"


Replace hardcoded user-specific paths with generic placeholders or relative paths to make the documentation portable across different development environments.

PULL_REQUEST_DESCRIPTION.md

+
+Terminal 1 - Backend:
+```bash
+cd "c:\Users\PRAJWAL\OneDrive\Desktop\quantresearch\QuantResearch"


Replace hardcoded user-specific paths with generic placeholders to make the documentation reusable for all developers.
