The Watcher - An agentic system troubleshooting tool powered by Claude

Uatu

Your AI partner for system operations—from guided troubleshooting to autonomous problem-solving.

Core capabilities:

• Chat with your system: Ask questions and get AI-powered analysis
• One-shot investigations: Instant diagnosis for specific issues
• Autonomous monitoring: Learn baselines and detect anomalies
• Intelligent analysis: Connect CPU spikes, memory leaks, and process behavior
• Cost-efficient: Prompt caching and smart rate limiting

Tested on Platforms:

• macOS
• Linux

Installation

Using pipx (recommended)

# Install with pipx for isolated environment
pipx install uatu

# Configure API key
echo "ANTHROPIC_API_KEY=your_key" > .env

Using pip

# Install globally or in a virtual environment
pip install uatu

# Configure API key
echo "ANTHROPIC_API_KEY=your_key" > .env

From source with uv

# Install uv (if not already installed)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Clone and install
git clone https://github.com/fractalops/uatu.git
cd uatu
uv sync

# Configure API key
echo "ANTHROPIC_API_KEY=your_key" > .env

Quick Start

Interactive Chat Mode (Default)

Start a conversational troubleshooting session:

# Default (read-only, requires approval for bash commands)
uv run uatu

# Allow bash commands with approval prompts
UATU_READ_ONLY=false uv run uatu

Ask questions naturally and get AI-powered analysis:

• "What's causing high CPU usage?"
• "Why is my server running slowly?"
• "Investigate recent memory issues"
• "Check for network bottlenecks"

Security: By default, bash commands require user approval. Set UATU_READ_ONLY=false in .env to enable bash (with approval prompts).

One-Shot Investigation

Investigate a specific symptom immediately:

uv run uatu investigate "server running slowly"
uv run uatu investigate "high CPU usage"
uv run uatu investigate "memory leak suspected"

The agent will:

• Gather relevant system information using bash commands
• Analyze patterns and correlate signals
• Provide root cause analysis
• Suggest actionable remediation steps

Best for: Quick diagnostics, automation, scripting

Continuous Monitoring

Watch your system and detect anomalies autonomously:

# Fast testing (1 minute baseline)
uv run uatu watch --baseline 1

# Production monitoring (5 minute baseline, default)
uv run uatu watch

# With AI investigation of detected anomalies
uv run uatu watch --investigate

Configuration

Create .env with options:

# Required
ANTHROPIC_API_KEY=your_key

# Optional
UATU_MODEL=claude-sonnet-4-5-20250929  # Claude model to use
UATU_READ_ONLY=true                     # Agent can only read, not modify system
UATU_REQUIRE_APPROVAL=true              # Require approval for risky actions

Development

# Run tests (20 unit tests)
uv run pytest

# Lint
uv run ruff check .

# Format
uv run ruff format .
