Tianshu (天枢) is a terminal programming Agent runtime based on harness engineering (Tui X Gui), deeply adapted for DeepSeek V4 with prefix-cache engineering optimizations achieving a measured steady-state hit rate of 97–99% in long sessions. It moves beyond the limitations of traditional AI programming assistants that treat large models merely as “tools,” using a cognitive virtual machine (CVM), a self-awareness layer, and self-decaying pheromone (Stigmergy) memory to make AI a “development partn
Tianshu Harness is a TypeScript runtime for coding agents, with terminal and desktop interfaces that share an agent core for managing goals, state, evidence, permissions, and completion checks. Developers use it to have language models carry out software tasks while the runtime verifies progress through tests, diffs, or other commands. The catalogue entries are skills and instructions for the agent's coding workflow.
