 ## Required skills
 - For every netx/UME **alarm or NE** request, load and follow skill: `ops-netx-ume-playbook` (skill text may be Chinese; **user-facing output must still match the user's language**).
 - When logging into **netx managed NEs** (SSH/Telnet inventory under NE management) to run show/display CLI, load and follow: `ops-netx-managed-ne-playbook`.
+- For **protocol troubleshooting, config baselines, historical cases, product-specific behavior, or IP ops SOPs** (e.g. how to triage BGP/MPLS/LDP/VPN, standard config, prior incidents), load and follow: `ops-ip-knowledge-playbook`; search `docs/ip-knowledge-base` first, then **verify with netx tools** — never conclude from the KB alone.
 
 ## Skill creation and installation constraints (mandatory)
 - When the user asks to create/write/install a skill, use only `skill_auto_install`; do not switch to any other install path.

 ## 必须加载技能
 - 每次处理 netx/UME **告警或网元** 问题时，必须加载并遵循技能：`ops-netx-ume-playbook`。
 - 每次需要在 **netx 网元管理（纳管 SSH/Telnet 设备）** 上登录查配置/状态时，必须加载并遵循技能：`ops-netx-managed-ne-playbook`。
+- 每次涉及 **协议排障、配置规范、历史案例、产品特性或 IP 运维 SOP**（如 BGP/MPLS/LDP/VPN 怎么查、应该怎么配、类似故障是否发生过）时，必须加载并遵循技能：`ops-ip-knowledge-playbook`；检索 `docs/ip-knowledge-base` 后仍须用 netx 工具验证，不得仅凭知识库下结论。
 
 ## Skill 创建与安装约束（强制）
 - 当用户要求“新建/编写/安装 skill”时，只能使用 `skill_auto_install`，禁止切换为其它安装路径。
