dsh-tool-calculator

In the daily reasoning of DeepSeek Agents, arithmetic calculation has always been a pain point. While the built-in bash tool can handle simple arithmetic via echo, each invocation spawns a new process, which is particularly slow on Windows and leads to significant cumulative latency with frequent use. Moreover, bash's limited arithmetic syntax does not support functions like sqrt, sin, or cos, forcing Agents to guess or write extra scripts for complex calculations, hurting efficiency and accuracy.

To address these issues, the dsh-tool-calculator plugin offers a safe and efficient mathematical expression evaluator. Built with a hand-written recursive descent parser, it completely avoids dangerous operations like eval or new Function, ensuring secure execution. With zero dependencies and zero process overhead, it performs calculations in milliseconds through pure function calls, supporting basic arithmetic operations, common math functions (e.g., abs, sin, log), and constants PI and E, covering most elementary mathematical needs.

This plugin is ideal for DeepSeek Agent developers and users, especially those requiring frequent mathematical calculations or complex expression handling. Whether for simple arithmetic verification or scientific computation, it provides stable, fast calculation support, enhancing the overall performance and user experience of the Agent.
