  "text": "// HarnessX: Harnesses You Compile, Not Hand-Build //\n\n(bookmark it)\n\nMost agent harnesses are hand-crafted and frozen. Each new model or task means rewriting the prompts, tools, memory, and control flow from scratch, and the rich traces from every run get thrown away.\n\nHarnessX treats the harness as something you assemble from typed primitives through a substitution algebra, then evolves with AEGIS, a trace-driven multi-agent engine that feeds execution history back into the design.\n\nWhy does it matter?\n\nIf the scaffolding can compose and improve itself from its own traces, the per-model rewrite tax that quietly dominates agent engineering starts to disappear. This is the cleanest version yet of treating the harness as a first-class, programmable artifact.\n\nPaper: https://t.co/zvz5YTLRZr\n\nLearn to build effective AI agents in our academy: https://t.co/LRnpZN7L4c",
