用 Jev 搭生产级编码 Agent 的 14 页实现指南
作者给出完整代码库:TypeSafe SDK 共享运行时、权限闸门、工具/MCP 路由、上下文压缩与成本感知模型路由,把 Jev 当编码 Agent 的决策层。


JEV IS THE DECISION LAYER CODING AGENTS WERE MISSING i wrote a 14-page implementation guide on exactly how to turn Jev into a production coding agent, along with the COMPLETE CODEBASE here is how you set it up: 1. the shared runtime you install once: one http://core.py on the TypeSafe SDK with bounded retries, and a trace file with a state hash for every decision the agent makes 2. the permission gate that approves, blocks or escalates every action before it runs. every option set includes none, human or a safe fallback, so the agent never has to guess 3. the tool and MCP router that loads only the tools the current task needs, plus dynamic context that picks the relevant files, messages and outputs instead of stuffing in the whole repo 4. query-aware compaction that compresses history around the next task, and a cost-aware model router that switches models only when the total context economics justify it 5. dynamic subagents with isolated context, a conditional AGENTS.md loaded by task, file and directory, and structured skills that can change tools, policies and hooks 6. security-aware routing by data sensitivity and provider policy, and a background review system that runs read-only tests, security checks and cross-model review in parallel every module is one file. copy the filename, activate the env, run the command. here is the full guide:
