Reasonix reasonix

Reasonix is a terminal-first AI agent designed to interact directly with DeepSeek's API. It is optimized for long-term use and cost efficiency, leveraging DeepSeek's byte-stable prefix cache to achieve high cache hit rates (90%+) in extended sessions, thereby significantly reducing input-token costs.

Key Features:

• Cache-First Loop: Maintains an append-only history aligned with DeepSeek's prefix cache, ensuring minimal computation for repeated content and cost savings of up to 80% on input tokens.
• Single Binary Design: Built as a CGO-free Go binary, it is cross-platform (macOS, Linux, Windows) and requires no external runtime dependencies.
• CLI + Web Interface: Operates seamlessly in the terminal while offering an optional browser-based UI for enhanced functionality, including approvals, goal management, and cost tracking.
• Subagents & Skills: Supports specialized sub-agents for tasks like exploration, research, code review, and security audits, along with Markdown skill scripts that integrate isolated tools.
• Plan Mode & Sandbox: Includes a plan mode to gate session writes until approved, ensuring controlled access to filesystem operations. Writers are jailed to the workspace for added security.

Audience & Benefit:
Ideal for developers, engineers, and teams requiring long-running, cost-effective AI interactions. Reasonix minimizes API costs over time while maintaining high performance, making it a reliable tool for continuous workloads in terminal environments. It can be installed via winget for easy setup.
