用 Jev 单次选择修掉 agent 错误工具循环
五步方案：不让 LLM 自由挑工具，改由 Jev 在工具名加 none 中单选，按置信度放行并打断重复失败循环。
Jev Engineering explained: how to kill the wrong-tool loop before it burns your budget one wrong tool call. then a retry. then another. you pay frontier prices for every lap here's the full fix in 5 steps: step 1 → stop letting the LLM free-pick tools. with a dozen tools, that's exactly where wrong-tool loops start step 2 → ask Jev one choice over your tool names plus "none". one valid key comes back, never a tool that doesn't exist step 3 → rebuild the tool list every step. a stale list makes Jev pick from options that no longer exist step 4 → gate on confidence. a confident winner runs. "none" or a shaky score and the agent reasons in prose instead of forcing a call step 5 → kill the lap. same tool, same failure again? Jev flags "repeating without progress" and the loop breaks: new strategy or a human 70-500ms per pick. the wrong call dies before the retry starts. works in Claude Code, Codex and Cursor via jev-mcp save this one ↓
