Darwin Skill 2.0 (达尔文.skill 2.0): autonomous skill optimizer, v2.0 integrates Microsoft Research SkillLens (arXiv 2605.23899) 9-dim rubric + SkillOpt (arXiv 2605.23904) validation-gated design + human-in-the-loop checkpoints. Evaluates SKILL.md files using a 9-dimension rubric (structure + effectiveness + meta-skill blacklists), runs hill-climbing with git version control, spawns independent judge agents for blind evaluation, validates improvements through test prompts with auto-break on diminishing returns, and generates visual result cards. Use when user mentions "优化skill", "skill评分", "自动优化", "auto optimize", "skill质量检查", "达尔文", "darwin", "帮我改改skill", "skill怎么样", "提升skill质量", "skill review", "skill打分".

Rewrite public source URLs (non-image) to the user's internal proxies (Nexus / chfs / Aliyun ACR). Use whenever a script, YAML, or command references raw.githubusercontent.com, github.com release ZIPs, upstream Helm chart repos, or other public file/binary downloads. Triggers on phrases like "github 拉不动", "raw 拉不动", "换成 Nexus", "走 chfs", "raw.githubusercontent", "release 下载不动". DO NOT rewrite container image references — containerd mirror config handles those transparently (keep upstream image refs in YAML/Dockerfile unchanged). Also use when authoring new install.sh in this repo — public file URLs should be rewritten by default.

Diagnose and safely clean up stuck Kubernetes resources — Terminating CR/namespace, RBAC residuals after operator removal, dead admission webhooks silently blocking API. Use when user mentions 卡 Terminating, kubectl delete 卡住, 卸载残留, RBAC forbidden, webhook 拦 API, namespace 删不掉, finalizer 卡, operator 没清干净, calico/cilium/cert-manager 卸载. Provides ordered diagnosis (CR → ns → ClusterRole → webhook), strip-finalizer-first patterns, operator-managed RBAC cleanup, and immediate unstick commands.

Production-grade Kubernetes YAML standards calibrated to this repo's actual conventions (Jenkins $VARS templating, Harbor imagePullSecrets, tcpSocket probes, multi-cluster overlays under devops/<env>/). Use BEFORE writing or modifying any K8s YAML for production — Deployment / StatefulSet / DaemonSet / Service / Ingress / HPA / PDB / NetworkPolicy / Job / CronJob. Triggers on:写 yaml,写 deployment,写 statefulset,k8s yaml,生产 yaml,业务 pod 模板,加 service,加 ingress,加 hpa,加 networkpolicy,写 cronjob,改副本数,加 probe,加 resources,deploy 模板. Provides必查清单 + 本仓库基线模板 + 各 kind 关键字段 + 反模式。

Apply this repo's editing conventions when modifying production configs under kubernetes/, devops/, docker/, network/, or any file marked ✅ 生产验证 in a README. Use whenever editing YAML, Dockerfile, .conf, .sh, install/uninstall scripts, or shell snippets in this knowledge base. Triggers on phrases like 改 yaml, patch 配置, 改生产文件, 改 devops, 改 kubernetes,, 改 calico, 改 nginx, 改 docker-compose, 加 env, 调整副本, 改镜像 tag. Enforces:do NOT reformat YAML, do NOT redact real IPs/passwords, list ≥3 file batches first, prompt before touching ✅生产 files, no auto-create README, use update-index for case-insensitive filename dupes.

Living catalog of script bugs and antipatterns hit in this repo — kubectl delete hangs, finalizer order, operator-managed RBAC, admission webhook residuals, iptables-restore footguns, curl | bash deadlocks, systemctl pager traps. Use BEFORE writing or modifying any install.sh / uninstall.sh / Dockerfile / shell automation script in this repo, AND when an existing script hangs/fails/produces unexpected results. Triggers on: 写脚本, 写 install, 写 uninstall, 改脚本, debug 脚本, 脚本卡住, 脚本不工作, kubectl delete 卡, 卸载脚本翻车, 脚本超时, bash script bug, shell pitfall, script antipattern. CONSULT THIS BEFORE WRITING — every bug here was painful to discover the first time.

Rewrite public source URLs (non-image) to the user's internal proxies (Nexus / chfs / Aliyun ACR). Use whenever a script, YAML, or command references raw.githubusercontent.com, github.com release ZIPs, upstream Helm chart repos, or other public file/binary downloads.
