# Cost Management

Oscar provides cost tracking and analysis for your cloud infrastructure. Configure cost data sources, monitor warehouse status, and get AI-powered spending insights.

## Setup Cost Tracking

Configure cost data sources with `/cost setup`:

```bash
/cost setup
```

Supports:

* **AWS** - Cost and Usage Reports (CUR)
* **Azure** - Cost Management exports

The setup wizard guides you through selecting your cloud provider, configuring export locations, setting up access credentials, and validating the configuration.

**AWS setup:**

## Check Warehouse Status

View your cost data warehouse status with `/cost status`:

```bash
/cost status
```

Shows:

* Configured cost sources
* Last sync time
* Data freshness
* Available date ranges
* Any sync errors or warnings

## Get Cost Summary

Analyze spending patterns with `/cost summary`:

```bash
/cost summary
```

Oscar analyzes your cost data and provides month-over-month spending trends, top cost drivers by service, unusual spending patterns, and cost optimization opportunities.

**Cost breakdown by service:**

See your spending organized by cloud service with month-over-month comparisons and percentage changes.

The summary is AI-generated based on your actual cost data, providing context-aware insights specific to your infrastructure.

## Cost Data Warehouse

Oscar uses DuckDB to create a local cost data warehouse. Cost data is:

* Synced from your cloud provider's cost exports
* Stored locally in `~/.config/oscar/cost/`
* Queried for analysis and reporting
* Never sent to external services (runs entirely locally)

## Notes

* Cost data requires initial setup via `/cost setup`
* First sync may take several minutes depending on data volume
* Data is refreshed automatically when you run `/cost status` or `/cost summary`
* Historical data availability depends on your cloud provider's export retention
* All cost analysis runs locally using DuckDB
