+<summary>Action Approval (HITL)</summary>
+
+By default, shell commands (`execute` tool) require human approval before running. To skip approval prompts:
+
+```bash
+# Per-session: auto-approve via CLI flag
+EvoSci --auto-approve
+EvoSci -p "query" --auto-approve
+
+# Persistent: set in config (applies to all future sessions)
+EvoSci config set auto_approve true
+
+# Or allow only specific command prefixes
+EvoSci config set shell_allow_list "python,pip,pytest,ruff,git"
+```
+
+During a session you can also reply **3** (Approve all) at any approval prompt to auto-approve for the rest of that session.

+# 单次会话：通过 CLI 参数启用自动审批
+EvoSci --auto-approve
+EvoSci -p "query" --auto-approve
+
+# 持久化：写入配置（对所有后续会话生效）

+```
+
+会话中也可以在审批提示时回复 **3**（Approve all），仅对当次会话自动审批后续所有操作。
