# ============================================================
# AI Command Center — Environment Variables
# ============================================================
# RENAME THIS FILE TO: .env (in project root or backend root)
# The FastAPI backend reads these at startup via python-dotenv.
# The React frontend reads API keys from localStorage (Settings page).
# ============================================================

# ── Core Paths ────────────────────────────────────────────────

# Root directory where all AI tools are installed
AI_ROOT=C:\path\to\your\AI_tools

# Backend server config
BACKEND_HOST=127.0.0.1
BACKEND_PORT=8000

# Frontend dev server (for CORS allowlist — don't change unless you change Vite config)
FRONTEND_PORT=5173

# Tauri dev port (for CORS allowlist)
TAURI_DEV_PORT=1420

# ── API Keys (Backend-side, optional) ─────────────────────────
# These are only needed if you run the AI Proxy (Task 9).
# Without these, AI features still work via direct browser calls
# using keys stored in the frontend Settings page (localStorage).

# OpenRouter API key (for AI chat/analysis proxy)
# Get yours at: https://openrouter.ai/keys
OPENROUTER_API_KEY=

# ── Optional: Community API Keys (for backend-proxied requests) ─
# The frontend already calls these directly from the browser.
# Backend proxying is an optional upgrade for rate limit avoidance.

# GitHub Personal Access Token (public repos, no special scopes needed)
# Create at: https://github.com/settings/tokens

# HuggingFace API token (read access)

# ── GPU / CUDA Settings ──────────────────────────────────────
# These are typically set system-wide by RTX5090_FULL_SETUP.bat
# via `setx /M`. Listed here for reference only.

# NVIDIA_TF32_OVERRIDE=1
# PYTORCH_CUDA_ALLOC_CONF=expandable_segments:True,garbage_collection_threshold:0.8

# ── Per-Session Performance Flags ─────────────────────────────
# Set by LAUNCH_*.bat launchers (not persisted system-wide).
# Listed here for reference if you need to debug launch issues.

# CUDA_MODULE_LOADING=LAZY
# HF_HUB_ENABLE_HF_TRANSFER=1
# TORCH_CUDNN_V8_API_ENABLED=1

# ── AI Model Default ─────────────────────────────────────────
# Default model for AI features. Users can override in Settings.
# This is only used by the backend AI proxy (Task 9).
DEFAULT_AI_MODEL=anthropic/claude-sonnet-4-20250514

# ── Tool Installation Paths (auto-detected, override if non-standard) ─
# Uncomment and set only if your tools are installed in non-default locations.
