# Ten Algebra

> Use this tool when you need to process and exchange structured messages between agents, and require a formal algebra to build, serialize, and verify expressions. Ten Algebra solves problems of message composition, encoding, and verification, providing a payload encoding layer for inter-agent protocols. It takes algebraic expressions as input and outputs serialized messages with sortable headers and variable-resolution encoding.
