It detects GPU memory bottlenecks, inefficient loop structures, and suggests hardware-native optimizations (like `bfloat16` for AMD MI300X). + - **Fix Agent:** Automatically generates unified Git-style diffs and line-by-line patch recommendations for every finding. + - **AMD Migration Advisor:** Scans for 10 categories of CUDA-specific patterns (nvidia-smi, CUDA_VISIBLE_DEVICES, BitsAndBytes, cuDNN, FP16 usage, etc.) and provides actionable ROCm/HIP migration guidance with a 0–100 AMD Compatibility Score. +- **⚡ AMD MI300X Live Metrics:** Real-time GPU performance monitoring (utilization, VRAM, temperature, power draw, inference speed) streamed to the dashboard during every scan via SSE.

The Backend (`/codesentry-backend`) +A high-performance **FastAPI** server that acts as the orchestrator. +- Ingests code via GitHub URLs, Hugging Face Spaces URLs, Zip files, or raw code snippets. +- Manages the stateful analysis session and memory lifecycle. +- Runs **AMD MI300X live metrics polling** via `rocm-smi` (with simulated fallback for dev environments). +- Runs the **AMD Migration Advisor** to detect CUDA-specific patterns and calculate an AMD Compatibility Score. +- Connects to an LLM endpoint (optimized for local deployment via `vLLM` on AMD hardware, using Qwen2.5-Coder-32B) to power the intelligent agents. + +### 2. The Frontend (`/codesentry-frontend`) +A modern **React + Vite** dashboard built with a premium, cyberpunk-inspired terminal aesthetic. +- Connects to the backend via SSE for live streaming. +- Features the **AMD MI300X Live Performance Card** in the Analysis View — 6 GPU metrics updated every 2 seconds. +- Features the **AMD ROCm Migration Advisor Panel** in the Report View — animated score circle, collapsible findings, and one-click `AMD_MIGRATION_GUIDE.md` export. +- Dynamic data visualization, animated severity charts, and side-by-side Before/After code diffing for AI-generated fixes. + +--- + +## 🔴 AMD-Specific Features + +### Live Hardware Metrics (Analysis View) +During every scan, CodeSentry polls the AMD MI300X GPU via `rocm-smi` and streams live metrics to the dashboard: + +| Metric | Description | +|--------|-------------| +| GPU Utilization | Current compute load (%) | +| VRAM Used | GB used / 192 GB total with visual bar | +| Memory Bandwidth | TB/s data throughput | +| Temperature | GPU edge temperature (°C) | +| Power Draw | Current wattage consumption (W) | +| Inference Speed | LLM tokens per second | + +> On development machines without AMD hardware, the card displays realistic simulated values. + +### CUDA → ROCm Migration Advisor (Report View) +The Migration Advisor scans code for 10 categories of CUDA-specific patterns: + +| ID | Severity | What It Detects | +|----|----------|-----------------| +| AMD_M01 | Low | `torch.cuda.is_available()` — CUDA device check | +| AMD_M02 | **Critical** | `nvidia-smi` — NVIDIA-only CLI tool | +| AMD_M03 | High | `CUDA_VISIBLE_DEVICES` — CUDA env variable | +| AMD_M04 | High | `torch.cuda.amp.autocast/GradScaler` — Legacy CUDA AMP | +| AMD_M05 | Medium | `.half()` / `torch.float16` — FP16 suboptimal on MI300X | +| AMD_M06 | Medium | `torch.backends.cudnn.*` — cuDNN configuration | +| AMD_M07 | High | `import flash_attn` — CUDA-only Flash Attention | +| AMD_M08 | Low | `torch.cuda.memory_allocated()` — CUDA memory profiling | +| AMD_M09 | Low | `device = 'cuda'` — Hardcoded device string | +| AMD_M10 | **Critical** | `BitsAndBytesConfig` — CUDA-only quantization | + +**Compatibility Scoring:** +``` +≥ 90% → "Fully ROCm Ready" (green) +≥ 70% → "Mostly Compatible" (yellow) +≥ 50% → "Needs Migration Work" (orange) +< 50% → "CUDA-Specific Codebase" (red) +``` + +--- + +## 💡 How It Works (An Example Workflow) + +To understand CodeSentry, imagine you have a Python scraping script that takes user input and feeds it into an LLM. + +1. **Initiate Scan:** You paste the GitHub or Hugging Face Space URL of the script into the CodeSentry dashboard. +2. **Live GPU Monitoring:** The AMD MI300X Live Performance card immediately starts showing real-time GPU utilization, VRAM usage, temperature, and inference speed. +3. **Security Sweep:** The Security Agent immediately flags `cli.py:61` for a **Prompt Injection** (CWE-74) vulnerability because it detects raw user input being passed to the model without sanitization. +4. **Performance Sweep:** The Performance Agent notices the code is loading a large transformer model inside a loop. It flags this and estimates you are wasting significant inference time. +5. **AMD Migration Scan:** The Migration Advisor detects `nvidia-smi` calls and `CUDA_VISIBLE_DEVICES` usage, calculating an AMD Compatibility Score and suggesting `rocm-smi` and `HIP_VISIBLE_DEVICES` replacements. +6. **Fix Generation:** The Fix Agent takes these findings and writes a patch. It refactors the prompt injection to use a parameterized template and hoists the model initialization outside the loop. +7. **Review:** You view the dashboard. The findings are categorized by severity. You click on the Prompt Injection finding, and an AI-Generated Fix panel opens showing exactly what lines to change. The AMD Migration Panel shows your compatibility score with collapsible fix guidance. +8. **Export:** You click "Copy PR Description" and paste a perfectly formatted summary of the fixes directly into your GitHub Pull Request. You also export the `AMD_MIGRATION_GUIDE.md` for your DevOps team. + +--- + +## 🚀 Installation & Setup + +### Prerequisites +- Node.js (v20.19+ or v22.12+) +- Python (v3.10+) +- An API Key for your LLM provider (e.g., Groq) if not running a completely local vLLM instance. + +### 1.
