Perihelion: Ultra-lightweight coding agent in Rust

🛠 Perihelion (peri) — Ultra-lightweight coding agent in Rust

The project weighs only 13 MB and consumes approximately 50 MB of RAM, while remaining fully compatible with Claude Code plugins, skills, and MCP tools. The agent supports working with any LLM (Anthropic, OpenAI, DeepSeek, Qwen) via the Agent Client Protocol (ACP).

🌍 A demonstration that high-performance AI tools can be implemented in systems languages with minimal resources, while maintaining compatibility with the Claude Code and MCP ecosystems.

👤 The ability to use powerful agentic functionality without heavy Node.js dependencies, with support for different models and easy switching between them.
