+# Gemini Global Configuration
+
+This document outlines my general preferences for working with Gemini.
+
+## General Principles
+
+- **Programming Style**: Please use a functional programming style whenever possible and appropriate for the language.
+- **Immutability**: Favor immutable data structures and variables where practical.
+- **Verification**: Do not run tests or build commands. I will handle verification myself.
+- **Dependencies**: If a new third-party library is needed, propose it and wait for my explicit approval before adding it to the project.
+- **Documentation**: Use descriptive function and variable names to make code self-documenting. Doc comments should generally only be used for functions that are part of a public or library API.
+- **Handling Ambiguity**: If a request is unclear or could be interpreted in multiple ways, always stop and ask for clarification.
+- **Logging**: Unless instructed otherwise, add descriptive logging statements for errors. For logical flows, add messages like "Starting {logic}" and "Successfully completed {logic}".
+- **API Design**: While not a primary task, prefer `snake_case` for JSON field names. Above all, always remain consistent with the conventions of the current project.
+
+
+## Language-Specific Guidelines
+
+### Formatting
+- **Java**: Adhere to the Google Java Style Guide.
+- **C++**: Use the default formatting provided by `clangd`.
+- **Python**: Format code using the `black` code formatter.
+- **Rust**: Format code using the default `rust-fmt` configuration.
+
+### Error Handling
+- **Rust**: Always return a `Result` type instead of panicking.
+- **Java & Python**: Throw exceptions for error conditions.
+- **C++**: Use a "Look Before You Leap" (LBYL) approach, checking preconditions to avoid errors.
+
+### Functional Programming
+- **Java**: Prioritize the use of functional features like the Stream API.
+- **C++**: Prioritize the use of modern C++ features that support a functional style, such as lambdas and ranges.
