Features

• Zero Bloat: Minimal, blazing-fast bundle (under 30KB) compiled using esbuild. No webviews, database layers, or heavy client SDKs.
• Five Core Providers: OpenAI, Anthropic, Google Gemini, OpenRouter, and Ollama.
• Dynamic Model Fetching: Pulls active, up-to-date lists of models straight from the provider APIs. If keys are missing or offline, enter any custom model identifier manually.
• Smart Diff Compactor: Automatically filters out lockfiles, generated assets, binary files, and minified code, enforcing a safe 30k character limit to protect against rate limits and token window errors.
• Context Aware: Optionally scans files like CHANGELOG.md or user-defined documentation in your workspace root, feeding the recent history to the LLM to align your commit message style and version numbers automatically.
• Customizable Prompt: Define your own system prompt and temperature parameters to enforce Conventional Commits or custom naming conventions.
• Secure Key Storage: Uses VS Code's native SecretStorage to keep your API keys safe.
• Status Bar Integration: Shows the currently active model. Click to swap models or providers instantly.
• Interruptible: Full cancel support for aborting in-progress LLM calls.
