<task>
Create a complete Rust plugin named [plugin name] that [desired functionality]. Integrate it with [target application or plugin host] using [integration mechanism].
</task>
<context>
Plugin purpose: [plugin purpose]
Target environment: [target operating system, application, or platform]
Expected inputs: [plugin inputs]

- Handle errors clearly and validate all external inputs.
- Avoid unsafe code unless [unsafe requirements] explicitly require it.
- Include comprehensive unit tests and integration tests for [critical behaviors].
- Provide all configuration, dependency, installation, and usage details.
