# Limitations

The following limitations apply to the current release of Fathom. These areas are expected to improve in upcoming versions.

#### Platform Support

Fathom currently supports Android only. Support for additional platforms will be evaluated and introduced in future releases.

#### Test Case Length

Fathom performs best with short to medium length test scenarios.

**Recommended test case size:** approximately 20–25 steps per test case.

Longer test cases may cause the agent to lose context during execution, which can result in missed steps or inconsistent behavior. Future improvements will focus on context stability for longer flows.

#### Unsupported Command Types

The following command types are not supported during intent-based test generation in the current release:

1. API commands
2. Module commands
3. Store commands
