Sentrux

The sensor that helps AI agents close the feedback loop.Recursive self-improvement of code quality.

Live: Claude Code Opus 4.6 builds a FastAPI project. Even with good prompts, quality lands at 6772.

Not because the agent can't do better — but because without a sensor, it doesn't know what to improve.

How it works

Quick Start

Install (macOS · Linux · Windows)

macOS

brew install sentrux/tap/sentrux

Linux

curl -fsSL https://raw.githubusercontent.com/sentrux/sentrux/main/install.sh | sh

Windows — download from Releases, or:

curl -L -o sentrux.exe https://github.com/sentrux/sentrux/releases/latest/download/sentrux-windows-x86_64.exe

Pure Rust. Single binary. No runtime dependencies. 52 languages via tree-sitter plugins. Runs on macOS, Linux, and Windows.

Run it

sentrux                    # open the GUI — live treemap of your project
sentrux /path/to/project   # open GUI scanning a specific directory
sentrux check .            # check rules (CI-friendly, exits 0 or 1)
sentrux gate --save .      # save baseline before agent session
sentrux gate .             # compare after — catches degradation

Connect to your AI agent (optional)

Give your agent real-time access to structural health via MCP.

Claude Code:

/plugin marketplace add sentrux/sentrux
/plugin install sentrux

Cursor / Windsurf / OpenCode / OpenClaw / any MCP client — add to your MCP config:

{
  "mcpServers": {
    "sentrux": {
      "command": "sentrux",
      "args": ["--mcp"]
    }
  }
}

From source / upgrade / troubleshooting

# Build from source
git clone https://github.com/sentrux/sentrux.git
cd sentrux && cargo build --release

# Upgrade
brew update && brew upgrade sentrux
# or re-run the curl install — it always pulls the latest release

Linux GPU issues? If the app won't start, sentrux automatically tries multiple GPU backends (Vulkan → GL → fallback). You can also force one:

WGPU_BACKEND=vulkan sentrux    # force Vulkan
WGPU_BACKEND=gl sentrux        # force OpenGL

The problem nobody talks about

You start a project with Claude Code or Cursor. Day one is magic. The agent writes clean code, understands your intent, ships features fast.

Then something shifts.

The agent starts hallucinating functions that don't exist. It puts new code in the wrong place. It introduces bugs in files it touched yesterday. You ask for a simple feature and it breaks three other things. You're spending more time fixing the agent's output than writing it yourself.

Everyone assumes the AI got worse. It didn't. Your codebase did.

Here's what actually happened: when you used an IDE, you saw the file tree. You opened files. You built a mental model of the architecture — which module does what, how they connect, where things belong. You were the governor. Every edit passed through your understanding of the whole.
