+# /cleanup — 垃圾代码审查与清理
+
+分析当前工作区（git diff）中的未提交代码，找出并修复常见垃圾代码，**不得改变任何运行逻辑**。
+
+## 检查范围
+
+若 `$ARGUMENTS` 非空，则只检查指定文件/目录；否则检查所有未提交修改（`git diff HEAD`）。
+
+## 节省上下文规则
+
+优先用确定性的 CLI 检查缩小范围，不要一上来把完整文件或大 diff 读入上下文：
+
+```bash
+git diff --name-only HEAD
+git diff --unified=0 HEAD -- <path>
+git diff --check
+rg -n "TODO|FIXME|console\.log|debugger|print\(" <changed-paths>
+```
+
+只有 focused diff 不足以安全判断或修改时，才读取完整文件。
+
+## 审查清单
+
+按优先级检查以下问题（只报告在本次 diff 中**新增或修改**的代码里存在的问题）：
+
+### 1. 重复逻辑 (Duplicate Logic)
+- 完全相同或高度相似的代码块在多处出现
+- 同一函数/方法被多个地方各自实现，已有公共版本未被复用
+- 相同的 DOM 查询、正则、模板字符串在同一文件重复
+
+### 2. Magic Numbers / Magic Strings
+- 裸数字直接参与计算（如偏移量、时间、尺寸、阈值），没有命名常量
+- 硬编码字符串（如 id 名、状态值、URL 片段）散落在逻辑中
+- 例外：`0`, `1`, `-1`, `100`, `""` 等语义明确的惯用值不算
+
+### 3. 命名问题
+- 含义不明的缩写变量（如 `or_`, `tmp2`, `x2`）
+- 命名与实际用途不符
+- 同一概念在不同地方用不同名字表达
+
+### 4. 死代码 / 无效代码
+- 注释掉的旧代码块（3行以上）
+- 声明后从未使用的变量/参数/导入
+- 永远不会执行的条件分支
+
+### 5. 代码风格问题
+- 尾部空白字符（trailing whitespace）
+- 同一文件内风格不一致（如混用单双引号、缩进不统一）
+- 空行使用不一致（连续多个空行等）
+
+### 6. 其他常见问题
+- 私有辅助函数应被 export 但没有，导致调用方重复实现
+- 类型/接口重复定义
+- 过于冗长的条件表达式可以简化（不改逻辑）
+
+## 执行步骤
+
+### Step 1 — 获取待检查文件列表
+
+```bash
+# 无参数时：获取所有未提交修改
+git diff HEAD --name-only
+
+# 有参数时：用 $ARGUMENTS 过滤
+```
+
+### Step 2 — 逐文件阅读并分析
+
+先从 focused diff 开始：
+
+```bash
+git diff --unified=0 HEAD -- <file>
+```
+
+用 `rg`、`git diff --check`、编译器或 linter 输出确认确定性问题。只有需要上下文时才用 Read 读取完整文件。对照审查清单，记录每个问题：文件名、行号、问题类型、建议修复方式。
+
+### Step 3 — 报告问题清单
+
+在修改前，先以列表形式输出所有发现的问题：
+
+```
+发现 N 个问题：
+
+[文件] js/foo.js
+  · L34, L78: 重复逻辑 — 两处都实现了相同的 DOM 查询，可提取到 getPanel()
+  · L91: Magic number — 硬编码 14 作为偏移量，应命名为 TOOLTIP_OFFSET
+
+[文件] js/bar.js
+  · L12: 命名问题 — 变量 `or_` 语义不明，应命名为 outerR/outerG/outerB
+  ...
+```
+
+如果没有发现问题，直接输出"未发现垃圾代码，当前代码质量良好。"并停止。
+
+### Step 4 — 执行修复
+
+对每个问题，使用 Edit 工具进行**最小化修改**：
+
+- **重复逻辑**：提取为共享常量/函数，更新所有调用点
+- **Magic number**：在文件顶部或逻辑附近声明 `const NAME = value`，替换所有引用
+- **命名问题**：重命名变量，更新所有使用处
+- **死代码**：直接删除
+- **尾部空白/风格**：修正
+- **未 export 的函数**：添加 `export`，在调用方改为导入（不重复实现）
+
+**修复原则：**
+- 只改在审查清单中发现的问题，不做额外优化
+- 每次 Edit 只修改确实有问题的行，保持 diff 最小
+- 改完后用 `grep` 验证旧的坏代码已消失
+- 优先做精确补丁；只有仓库已有对应格式化流程时，才运行格式化工具
+
+### Step 5 — 输出总结
+
+```
+清理完成：
+
+修复了 N 个问题：
+  ✓ earth.js — 提取重复 vertexShader 为 ATMOS_VERTEX_SHADER 常量
+  ✓ main.js — 提取 TOOLTIP_CURSOR_OFFSET = 14（4处引用）
+  ✓ controls.js — export updateLayerButtonState，移除 main.js 中的重复实现
+  ...
+
+未修改的问题（需人工确认）：
+  ! foo.js L45 — 注释代码块较长，建议手动确认是否可删除
+```
+
+## 约束
+
+- **禁止**改变函数签名、接口定义、导出 API（除非问题正是私有函数应被 export）
+- **禁止**添加新功能、新抽象、新参数
+- **禁止**修改注释内容（只删除注释掉的死代码）
+- **禁止**修改测试文件逻辑
+- 如果一个 Magic number 的语义不完全确定，**跳过**，在总结中标记为"需人工确认"

+description: 分析本次 git 变更，在 docs/technical/zh/ 中新建或更新对应的技术文档
+argument-hint: 可选：指定要记录的主题，或留空自动从 git diff 推断
+allowed-tools: ["Read", "Edit", "Write", "Bash", "Glob", "Grep"]
+---
+
+# /docs — 技术文档写入工作流
+
+## 目标
+
+根据当前 git 变更（或用户指定主题）在 `docs/technical/zh/` 中写入或更新技术文档，记录**为什么**这样做，而不只是记录做了什么。
+
+## 执行步骤
+
+### Step 1 — 理解变更范围
+
+```bash
+git diff HEAD --stat          # 变更文件一览
+git diff HEAD --name-only     # 变更文件列表
+git log --oneline -10         # 近期 commit 上下文
+```
+
+若 `$ARGUMENTS` 指定了主题，优先聚焦该主题；否则从文件列表和 diff stat 推断变更主题。不要默认读取完整仓库 diff；只对决定文档主题所需的文件读取 focused diff：
+
+```bash
+git diff HEAD -- <path>
+rg -n "class |def |function |export |router|@router|interface |type " <path>
+```
+
+### Step 2 — 确认文档范围
+
+分析变更，判断：
+
+1. **应写几篇文档**：单一主题写一篇，跨领域变更可拆分（如后端性能优化 + 运维启动脚本分开写）
+2. **是新建还是更新**：检查 `docs/technical/zh/` 中是否已有相关文档
+3. **文档命名**：按 `领域-主题-副题.md` 格式，全小写，用连字符，如：
+   - `backend-datasources-api-performance.md`
+   - `ops-planet-sh-startup.md`
+   - `earth-bgp-context.md`
+
+```bash
+ls docs/technical/zh/          # 查看现有文档
+```
+
+**先输出写作计划供用户确认**（若变更明确且范围小，可直接执行）：
+
+```
+文档计划：
+  新建：docs/technical/zh/ops-planet-sh-startup.md — planet.sh 启动性能优化
+  更新：docs/technical/zh/backend-datasources-api-performance.md — 补充并行化细节
+```
+
+### Step 2.5 — 覆盖范围检查
+
+写文档前必须按变更类型检查配套文档，不要只更新一篇专题文档：
+
+- 用户可见流程变化：更新 `docs/technical/zh/manual.md`，通常也更新 `docs/technical/zh/quickstart.md`。
+- `manual.md`、`quickstart.md` 这类用户手册存在英文版时，同步更新 `docs/technical/en/...`，至少避免英文版与中文版互相矛盾。
+- 控制台页面职责、路由入口、表格/抽屉/设置页行为变化：更新 `docs/technical/zh/frontend-admin-frontend-context.md`。
+- Earth 前端行为、HUD、巡航、图层、图例、交互变化：更新 `docs/technical/zh/earth-frontend-context.md`。
+- 新增 Earth 图层、调整 `renderOrder`、半径/高度偏移、深度策略、拾取策略、legend mode、图层面板顺序或启动加载顺序：更新 `docs/technical/zh/earth-render-layer-order.md`。
+- Earth 图层视觉样式、颜色、图例符号语义变化：若影响样式索引，同步更新 `docs/technical/zh/earth-layer-style-reference.md`。
+- 采集器、数据源、凭证、设置页、连接检查、scheduler、后端 API 变化：更新相关后端文档，优先检查 `docs/technical/zh/backend-collectors.md` 和 datasource/settings 专题文档。
+- 如果某个旧 plan 的假设已经被当前实现推翻，在对应 `docs/plans/*.md` 增加现状修正或更新该段，不要让计划文档继续给出相反方向。
+- 新增 technical 文档后，如果需要被发现，更新 `docs/technical/zh/README.md`。
+- 如果 technical 文档需要在公开 Docs 页面显示，或从 technical README 链接进入，必须同步更新 `frontend/src/pages/Docs/docs-content.ts` 的 `DOCS_METADATA`。前端使用这份白名单，`docs/technical/{zh,en}/` 中存在 `.md` 文件并不会自动生成路由。
+- 公开 technical 文档必须按同名文件维护中英文双语版本：`docs/technical/zh/<name>.md` 与 `docs/technical/en/<name>.md`。如果某篇文档刻意只保留单语，完成说明中必须明确写出原因。
+- 对本次变更提取旧词做 stale search，例如旧 tab 名、旧路由职责、旧认证假设、改名前 UI 文案：
+
+```bash
+rg -n "旧文案|旧路由职责|旧认证假设" docs/technical docs/plans
+```
+
+### Step 3 — 写文档
+
+遵循以下原则：
+
+**记录 WHY，不只记录 WHAT**
+- 好：`将戳文件从 /tmp 移到 ~/.cache/planet/，因为 WSL 重启后 /tmp 被清空`
+- 差：`修改了 AI_PROVIDER_BUILD_STAMP_FILE 的值`
+
+**必须包含的内容**：
+- 背景/问题：改动之前存在什么问题，为什么要改
+- 核心设计决策及其理由
+- 关键代码片段（用 diff 或 before/after 展示）
+- 相关文件列表
+
+**格式要求**：
+- 使用 `##` 和 `###` 分级，不要超过三级
+- 代码块注明语言（python / bash / typescript / sql）
+- 表格用于对比多个选项或列出参数
+- 中文写作，技术术语保留英文原文
+- `docs/technical/zh/` 中的文档不得用英文原文占位；如果存在 `docs/technical/en/` 对应文件，禁止逐字复制成中文文件
+- 中文文档内部链接应指向 `docs/technical/zh/...`，除非明确引用英文专属文档
+- 公开文档的 Markdown 链接显示文字应使用可读标题，不要直接暴露 `manual.md`、`earth-frontend-context.md` 这类裸文件名
+
+**文档结构模板**：
+
+```markdown
+# 标题（说明做了什么）
+
+## 背景
+
+为什么要做这个改动，改动前存在什么问题。
+
+## 核心变更
+
+### 子主题一
+
+before/after 或决策说明 + 关键代码
+
+### 子主题二
+
+...
+
+## 相关文件
+
+- `path/to/file.py` — 简短说明
+```
+
+### Step 4 — 验证
+
+- 读一遍写好的文档，确认逻辑清晰、代码片段无明显错误
+- 用 `rg --files` 或 `test -e` 确认文档中的文件路径在项目中真实存在，避免凭记忆判断：
+- 检查中文文档没有误复制英文版：
+
+```bash
+python - <<'PY'
+from pathlib import Path
+same = []
+for en in sorted(Path("docs/technical/en").glob("*.md")):
+    zh = Path("docs/technical/zh") / en.name
+    if zh.exists() and en.read_text() == zh.read_text():
+        same.append(en.name)
+if same:
+    raise SystemExit("identical en/zh docs: " + ", ".join(same))
+print("no identical en/zh docs")
+PY
+```
+
+- 检查中文文档内部链接没有继续指向无语言目录：
+
+```bash
+rg -n "/home/ray/dev/linkong/planet/docs/technical/(?!zh|en)" docs/technical/zh --pcre2
+```
+
+- 检查公开文档链接已进入 Docs 前端白名单。凡是 `docs/technical/{zh,en}/README.md` 中链接到的 technical `.md`，都必须存在于 `DOCS_METADATA`：
+
+```bash
+python - <<'PY'
+import re
+from pathlib import Path
+
+metadata = Path("frontend/src/pages/Docs/docs-content.ts").read_text()
+known = set(re.findall(r"'([^']+\.md)':\s*\{", metadata))
+known.add("README.md")
+
+missing = []
+for readme in [Path("docs/technical/zh/README.md"), Path("docs/technical/en/README.md")]:
+    if not readme.exists():
+        continue
+    for href in re.findall(r"\]\(([^)]+\.md)\)", readme.read_text()):
+        path = Path(href)
+        if "docs/technical/" not in href:
+            continue
+        filename = path.name
+        if filename not in known:
+            missing.append(f"{readme}: {filename}")
+
+if missing:
+    raise SystemExit("docs README links missing DOCS_METADATA: " + ", ".join(missing))
+print("docs README links are whitelisted")
+PY
+```
+
+- 检查公开文档双语同名文件齐备。除 `README.md` 外，所有白名单文档都应同时存在 zh/en 文件，除非本次说明中明确豁免：
+
+```bash
+python - <<'PY'
+import re
+from pathlib import Path
+
+metadata = Path("frontend/src/pages/Docs/docs-content.ts").read_text()
+filenames = sorted(set(re.findall(r"'([^']+\.md)':\s*\{", metadata)) - {"README.md"})
+missing = []
+for filename in filenames:
+    for lang in ("zh", "en"):
+        path = Path("docs/technical") / lang / filename
+        if not path.exists():
+            missing.append(str(path))
+if missing:
+    raise SystemExit("missing bilingual docs: " + ", ".join(missing))
+print("public docs have zh/en file pairs")
+PY
+```
+
+- 检查公开文档里没有用裸 `.md` 文件名当链接标题。这个命令在 polished public docs 中应无输出：
+
+```bash
+rg -n "\[[^]]+\.md\]\(" docs/technical/zh docs/technical/en
+```
+
+```bash
+# 对文档中提到的关键路径做快速验证
+ls <mentioned_paths>
+```
+
+如需检查大量链接，优先用确定性提取：
+
+```bash
+rg -n "\]\(([^)]+)\)" docs/technical/zh/<doc>.md
+```
+
+### Step 5 — 完成确认
+
+输出摘要：
+
+```
+✓ 新建：docs/technical/zh/ops-planet-sh-startup.md（约 xxx 字）
+✓ 更新：docs/technical/zh/backend-datasources-api-performance.md
+```
+
+## 注意事项
+
+- 不要写流水账式的"改了 A、改了 B、改了 C"，要写改动背后的约束和权衡
+- 不要在文档中引用 PR 号、issue 号、或当前对话——这些会随时间失效
+- 代码片段保持简洁，只保留说明问题的关键部分，省略无关样板代码
+- 如果某个变更已有文档记录，优先在原文档中追加，而不是新建
+- 公开 technical 文档没有注册 `DOCS_METADATA` 时，Docs 页面不会显示；不要只创建 `.md` 文件就结束。
+- 公开 technical 文档默认需要 zh/en 同名文件，不要只补一个语言版本。
+- 链接可见文字使用文档标题或语义标题，不要使用裸文件名。
+- 文档是给未来的开发者看的，假设读者熟悉项目但不了解这次改动的背景

+---
+
+# /goal-driven — 目标驱动执行模式
+
+使用 `lidangzzz/goal-driven` 的核心思想来推进复杂任务：先固定目标与成功标准，再持续执行和反复验收，直到标准真正满足。
+
+适用场景：
+
+- 长周期实现任务
+- 高复杂度工程任务
+- 可被明确验收的研究、实现、迁移、验证类工作
+
+不适用场景：
+
+- 纯脑暴
+- 无法定义成功标准的模糊任务
+- 很小的一次性修改
+
+## 输入要求
+
+若 `$ARGUMENTS` 只包含目标，没有成功标准，先补全一版可执行的成功标准再开始。
+
+启动时先输出：
+
+```md
+Goal
+- ...
+
+Criteria for success
+- ...
+
+Plan
+1. ...
+2. ...
+3. ...
+
+Verification
+- ...
+```
+
+## 执行规则
+
+1. 先把任务固化为两个核心块：
+   - `Goal`
+   - `Criteria for success`
+
+2. 成功标准必须尽量客观，可验证，可落地。
+   优先写成：
+   - 需要交付什么
+   - 需要通过哪些测试或验证
+   - 如何判断结果真的完成
+
+3. 进入持续执行循环：
+   - 完成一个阶段
+   - 检查当前结果是否满足成功标准
+   - 若未满足，明确剩余差距并继续推进
+
+4. 任何“完成了”“差不多了”“已实现”之类的结论，都必须经过验证，不能直接接受。
+
+5. 如果验证失败：
+   - 明确指出哪条成功标准没满足
+   - 继续工作，不要把阶段性进展误判为完成
+
+6. 只有在以下情况之一才能停止：
+   - 成功标准已满足
+   - 用户明确要求停止
+
+## 执行风格
+
+- 重证据，轻口头判断
+- 优先使用确定性工具证据：`rg`、`git diff --stat`、`git diff -- <path>`、测试、构建、lint、`curl`、数据库查询等能直接证明成功标准的方式
+- 不把大段命令输出粘进回复；保留在工具调用里，回复只总结关键证据
+- 重验收，轻自我感觉
+- 优先用测试、日志、产物、对比结果来证明完成
+- 对长期任务保持“未达标就继续”的节奏
+
+## 简版模板
+
+```md
+Goal: [[[[[在此填写最终目标]]]]]
+
+Criteria for success: [[[[[在此填写成功标准]]]]]
+
+循环执行：
+1. 推进任务
+2. 检查是否满足成功标准
+3. 若未满足，继续工作
+4. 直到满足标准或用户明确停止

+
+意图混合时以用户明确描述为准；bugfix + 小 feature 混合默认判定为 `improvement`（`+0.0.1`）。
+
+## 必须同步更新的文件
+
+使用 `git rev-parse --show-toplevel` 获取仓库根目录，以下路径均相对于根目录：
+
+- `VERSION`
+- `frontend/package.json`（`"version"` 字段）
+- `pyproject.toml`（`version =` 字段）
+- `uv.lock`（**不要手动编辑**，通过 `uv lock` 重新生成）
+- `docs/CHANGELOG.md`
+- `docs/version-history.md`
+
+## 节省上下文规则
+
+发版判断应以确定性 CLI 证据为主，优先使用紧凑命令和定点读取：
+
+```bash
+git status --short
+git diff --stat HEAD
+git diff --name-only HEAD
+rg -n "version|^## |^Released:|当前开发版本|current" VERSION frontend/package.json pyproject.toml docs/CHANGELOG.md docs/version-history.md
+```
+
+除非需要判断某个代码变更是否属于本次发版，否则不要读取完整 diff。
+
+## 执行步骤
+
+### Step 1 — 环境检查
+
+```bash
+git branch --show-current          # 确认在 dev 分支
+git status --short                 # 检查是否有无关的未暂存修改
+cat VERSION                        # 读取当前版本
+```
+
+若当前**不在 `dev` 分支**，停下来告知用户，不要继续。
+
+若存在无关的未暂存修改，列出并询问用户是否一并提交，或先 stash。
+
+### Step 2 — 确定发版类型与新版本号
+
+- 若 `$ARGUMENTS` 提供了明确类型（`feature` / `bugfix`），直接使用
+- 否则根据 `git diff --stat HEAD`、`git diff --name-only HEAD`、必要的 focused diff 和 `git log` 推断
+- 计算新版本号（例：`0.26.2` → bugfix → `0.26.3`）
+- **先输出发版计划供用户确认**：
+
+```
+发版计划：
+  类型：bugfix
+  版本：0.26.2 → 0.26.3
+  分支：dev
+  将更新：VERSION, frontend/package.json, pyproject.toml, uv.lock, CHANGELOG.md, version-history.md
+```
+
+### Step 3 — 更新版本号文件
+
+按顺序更新（每步用 Edit 工具，精确替换，不要重写整个文件）：
+
+1. `VERSION` — 直接替换全部内容为新版本号
+2. `frontend/package.json` — 替换 `"version": "x.x.x"` 行
+3. `pyproject.toml` — 替换 `version = "x.x.x"` 行
+4. 运行 `uv lock` 重新生成 `uv.lock`（在仓库根目录下执行）
+
+### Step 4 — 更新 CHANGELOG.md
+
+在文件顶部插入新条目，格式：
+
+```markdown
+## [x.x.x] — YYYY-MM-DD
+
+### ✨ Features / 🐛 Fixes / 🔧 Improvements
+- ...（只列高信号条目，最多 5 条）
+- ...
+
+---
+```
+
+日期使用 `date +%Y-%m-%d` 获取今天的日期。
+
+### Step 5 — 更新 docs/version-history.md
+
+- 更新文件头部的"当前开发版本"字段
+- 在时间线表格顶部插入新行：`| vx.x.x | YYYY-MM-DD | 一句话摘要 |`
+
+### Step 6 — 验证
+
+针对本次变更范围做最小验证：
+
+- Python 文件有修改：先用 `git diff --name-only HEAD -- '*.py'` 列出，再运行 `python3 -m py_compile <changed_files>`
+- Frontend 文件有修改：先用 `git diff --name-only HEAD -- frontend` 判断范围，再运行项目标准检查（若无则跳过并说明）
+- 版本号一致性检查：用 grep 确认 VERSION、package.json、pyproject.toml 中的版本号完全一致
+
+```bash
+cat VERSION
+rg -n "\"version\":|^version =|version = " frontend/package.json pyproject.toml uv.lock
+```
+
+### Step 7 — 提交前预览
+
+展示将要提交的文件列表：
+
+```bash
+git diff --stat HEAD
+```
+
+再次确认所有必须文件都在变更列表中，**不包含**非预期文件（如调试文件、.env 等）。
+
+### Step 8 — Commit & Push（用户确认后）
+
+```bash
+git add VERSION frontend/package.json pyproject.toml uv.lock docs/CHANGELOG.md docs/version-history.md
+# 若有代码变更也一并 stage
+git add <code_files>
+
+git commit -m "release: bump version to x.x.x"
+git tag vx.x.x
+git push origin dev
+git push origin vx.x.x
+```
+
+commit message 固定格式：`release: bump version to x.x.x`
+
+### Step 9 — 完成确认
+
+输出摘要：
+
+```
+✓ 版本号已更新：0.26.2 → 0.26.3
+✓ CHANGELOG 已更新
+✓ version-history 已更新
+✓ uv.lock 已重新生成
+✓ 验证通过
+✓ commit: release: bump version to 0.26.3
+✓ tag: v0.26.3
+✓ 已 push 到 origin/dev
+```
+
+## 注意事项
+
+- `uv.lock` 只能通过 `uv lock` 生成，绝不手动编辑
+- 发版 commit 只包含版本文件 + 本次功能代码，不混入无关改动
+- 若环境中 `uv` 不可用，说明原因并跳过 lockfile 更新，提醒用户手动运行

+
+# Cleanup
+
+Review and fix code quality issues in the current working tree without altering any logic or behavior.
+
+## When To Use
+
+- The user asks to clean up, tidy, or lint uncommitted changes
+- The user wants a code smell review before releasing or committing
+- The user mentions magic numbers, duplicate logic, dead code, or naming issues
+
+Do not refactor architecture, add features, or change behavior.
+
+## Scope
+
+If the user specifies a file or directory, check only that. Otherwise check all uncommitted changes (`git diff HEAD`).
+
+Only report issues present in **newly added or modified** lines of this diff — do not audit unchanged code.
+
+## Token-Saving Rule
+
+Prefer deterministic CLI checks before reading files into model context:
+
+```bash
+git diff --name-only HEAD
+git diff --unified=0 HEAD -- <path>
+git diff --check
+rg -n "TODO|FIXME|console\.log|debugger|print\(" <changed-paths>

+Read full files only when the focused diff does not provide enough surrounding context to make a safe edit.
+
+## Checklist
+
+### 1. Duplicate Logic
+- Identical or near-identical code blocks appearing in multiple places
+- A function/helper that already exists but is re-implemented elsewhere instead of being reused
+- Repeated DOM queries, regex literals, or template strings within the same file
+
+### 2. Magic Numbers / Magic Strings
+- Bare numeric literals used in calculations (offsets, timeouts, sizes, thresholds) without a named constant
+- Hardcoded strings (IDs, status values, URL fragments) scattered through logic
+- Exceptions: `0`, `1`, `-1`, `100`, `""` and other idiomatically clear values are fine
+
+### 3. Naming Issues
+- Cryptic abbreviations (`or_`, `tmp2`, `x2`)
+- Names that do not match actual behavior
+- The same concept referred to by different names in different places
+
+### 4. Dead Code
+- Commented-out code blocks (3+ lines)
+- Variables, parameters, or imports declared but never used
+- Branches that can never execute
+
+### 5. Style Inconsistencies
+- Trailing whitespace
+- Mixed quote styles or indentation within the same file
+- Inconsistent blank-line usage (multiple consecutive blank lines, etc.)
+
+### 6. Other
+- Private helper functions that should be exported but are not, causing callers to duplicate the implementation
+- Overly verbose conditions that can be simplified without changing logic
+
+## Steps
+
+### Step 1 — Get the file list
+
+```bash
+git diff HEAD --name-only
+```
+
+Filter to the user-specified path if one was provided.
+
+### Step 2 — Read and analyze each file
+
+Start with focused diffs:
+
+```bash
+git diff --unified=0 HEAD -- <file>
+```
+
+Use `rg`, `git diff --check`, and compiler/linter output for deterministic findings. Read the full file only for files that need surrounding context. For each issue found, record filename, line number, category, and suggested fix.
+
+### Step 3 — Report findings before touching anything
+
+Print a structured list:
+
+```
+Found N issues:
+
+[file] js/foo.js
+  · L34, L78: Duplicate logic — same DOM query implemented twice; extract to getPanel()
+  · L91: Magic number — bare 14 used as pixel offset; name it TOOLTIP_OFFSET
+
+[file] js/bar.js
+  · L12: Naming — variable `or_` is unclear; rename to outerR, outerG, outerB
+  ...
+```
+
+If no issues are found, output "No code smells detected. Code quality looks good." and stop.
+
+### Step 4 — Fix each issue
+
+Use the Edit tool for **minimal, targeted changes**:
+
+- **Duplicate logic**: extract to a shared constant or function; update all call sites
+- **Magic number/string**: declare `const NAME = value` near the top of the relevant scope; replace all usages
+- **Naming**: rename the variable/function; update all references
+- **Dead code**: delete it
+- **Trailing whitespace / style**: fix in place
+- **Unexported helper**: add `export`; update callers to import instead of re-implementing
+
+Principles:
+- Only fix issues identified in the checklist — no extra improvements
+- Keep each Edit as small as possible
+- After fixing, verify the old bad pattern is gone with grep
+- Prefer `apply_patch` for targeted edits; use formatters only when the repository already uses them for the touched file type
+
+### Step 5 — Summary
+
+```
+Cleanup complete:
+
+Fixed N issues:
+  ✓ earth.js — extracted duplicate vertexShader into ATMOS_VERTEX_SHADER constant
+  ✓ main.js — extracted TOOLTIP_CURSOR_OFFSET = 14 (4 references updated)
+  ✓ controls.js — exported updateLayerButtonState; removed duplicate implementation in main.js
+  ...
+
+Skipped (needs manual review):
+  ! foo.js L45 — large commented-out block; confirm it is safe to delete
+```
+
+## Constraints
+
+- **Do not** change function signatures, exported interfaces, or public APIs (unless the issue is a missing export)
+- **Do not** add new features, abstractions, or parameters
+- **Do not** rewrite comments (only delete commented-out dead code)
+- **Do not** touch test file logic
+- If a magic number's intent is uncertain, skip it and flag it in the summary

+description: Analyze current Planet repo changes and create or update technical documentation under docs/technical/zh. Use when the user asks to write docs, update technical docs, summarize implementation changes into documentation, or port the Claude docs-codex workflow into Codex.
+---
+
+# Docs
+
+Use this skill when the user asks to create or update Planet technical documentation, especially under `docs/technical/zh/`.
+
+## Goal
+
+Write or update technical docs that explain why a change exists, not only what files changed.
+
+Default target directory:
+
+- `docs/technical/zh/`
+
+## Workflow
+
+1. Gather change context:
+
+```bash
+git diff HEAD --stat
+git diff HEAD --name-only
+git log --oneline -10
+ls docs/technical/zh/
+```
+
+If the user gives a specific topic, focus on that topic. Otherwise infer the documentation topic from the file list and diff stat. Do **not** read the full repository diff by default; inspect focused diffs only for the files that define the doc topic:
+
+```bash
+git diff HEAD -- <path>
+rg -n "class |def |function |export |router|@router|interface |type " <path>
+```
+
+2. Decide document scope:
+
+- Use one document for one coherent topic.
+- Split documents when the changes cross meaningful domains, such as backend performance and ops startup behavior.
+- Prefer updating an existing relevant doc over creating a duplicate.
+- Name new files as lowercase hyphenated `domain-topic-detail.md`, for example:
+  - `backend-datasources-api-performance.md`
+  - `ops-planet-sh-startup.md`
+  - `earth-bgp-context.md`
+
+3. Apply the documentation coverage checklist before writing:
+
+- User-visible workflow changes must update `docs/technical/zh/manual.md` and usually `docs/technical/zh/quickstart.md`.
+- If an English counterpart exists for user-facing docs such as `manual.md` or `quickstart.md`, update `docs/technical/en/...` enough that it does not contradict the Chinese source.
+- Control console page responsibility changes must update `docs/technical/zh/frontend-admin-frontend-context.md`.
+- Earth frontend behavior changes must update `docs/technical/zh/earth-frontend-context.md`.
+- Earth layer additions, `renderOrder`, altitude/radius offsets, depth strategy, pointer picking, legend modes, or layer panel/startup ordering must update `docs/technical/zh/earth-render-layer-order.md`.
+- Earth layer visual style or legend symbol/color semantics should also update `docs/technical/zh/earth-layer-style-reference.md` when that reference is affected.
+- Collector, datasource, credential, settings, connectivity, scheduler, or API changes must update the relevant backend docs, especially `docs/technical/zh/backend-collectors.md` and any datasource/settings-specific doc.
+- When a change turns an old plan assumption into current behavior, update the relevant `docs/plans/*.md` with a status note instead of leaving contradictory instructions.
+- If adding a new technical document, add it to `docs/technical/zh/README.md` when it should be discoverable from the technical docs index.
+- If a technical document should be visible in the public Docs page or linked from a technical README, register it in `frontend/src/pages/Docs/docs-content.ts` under `DOCS_METADATA`. The frontend uses this whitelist; files under `docs/technical/{zh,en}/` are not automatically routable.
+- For every public technical doc, keep the bilingual file pair in sync by filename: `docs/technical/zh/<name>.md` and `docs/technical/en/<name>.md`. If the content is intentionally Chinese-only or English-only, state that intentionally in the final note.
+- Search docs for stale terms introduced by the change, for example old tab names, old route responsibilities, obsolete auth assumptions, or renamed UI labels.
+
+4. Write the doc in Chinese:
+
+- Write Chinese prose for `docs/technical/zh/`.
+- Keep technical identifiers, API paths, config keys, code symbols, and standard product names in English where appropriate.
+- Use `##` and `###` headings; avoid going deeper than three levels.
+- Use fenced code blocks with language tags.
+- Use tables when comparing options or listing parameters.
+
+5. Required content:
+
+- Background/problem: what was wrong before and why the change was needed.
+- Core design decisions and rationale.
+- Key code snippets, preferably before/after or focused excerpts.
+- Related files and what each file contributes.
+
+6. Verification:
+
+- Read the completed doc and check that the reasoning is clear.
+- Verify important referenced paths exist.
+- Use `rg --files` or `test -e` for path existence instead of relying on memory.
+- Run a quick duplicate-language check when editing bilingual docs:
+
+```bash
+python - <<'PY'
+from pathlib import Path
+same = []
+for en in sorted(Path("docs/technical/en").glob("*.md")):
+    zh = Path("docs/technical/zh") / en.name
+    if zh.exists() and en.read_text() == zh.read_text():
+        same.append(en.name)
+if same:
+    raise SystemExit("identical en/zh docs: " + ", ".join(same))
+print("no identical en/zh docs")
+PY
+```
+
+Also check that Chinese docs do not link to the old language-less technical docs path:
+
+```bash
+rg -n "/home/ray/dev/linkong/planet/docs/technical/(?!zh|en)" docs/technical/zh --pcre2
+```
+
+This command should return no matches.
+
+Check that public docs are whitelisted in the frontend Docs registry. Any `.md` linked from `docs/technical/{zh,en}/README.md` and located under `docs/technical/{zh,en}/` must have a matching `DOCS_METADATA` key:
+
+```bash
+python - <<'PY'
+import re
+from pathlib import Path
+
+metadata = Path("frontend/src/pages/Docs/docs-content.ts").read_text()
+known = set(re.findall(r"'([^']+\.md)':\s*\{", metadata))
+known.add("README.md")
+
+missing = []
+for readme in [Path("docs/technical/zh/README.md"), Path("docs/technical/en/README.md")]:
+    if not readme.exists():
+        continue
+    for href in re.findall(r"\]\(([^)]+\.md)\)", readme.read_text()):
+        path = Path(href)
+        if "docs/technical/" not in href:
+            continue
+        filename = path.name
+        if filename not in known:
+            missing.append(f"{readme}: {filename}")
+
+if missing:
+    raise SystemExit("docs README links missing DOCS_METADATA: " + ", ".join(missing))
+print("docs README links are whitelisted")
+PY
+```
+
+Check bilingual parity for public docs. Every whitelisted document except `README.md` should exist in both language directories unless intentionally documented otherwise:
+
+```bash
+python - <<'PY'
+import re
+from pathlib import Path
+
+metadata = Path("frontend/src/pages/Docs/docs-content.ts").read_text()
+filenames = sorted(set(re.findall(r"'([^']+\.md)':\s*\{", metadata)) - {"README.md"})
+missing = []
+for filename in filenames:
+    for lang in ("zh", "en"):
+        path = Path("docs/technical") / lang / filename
+        if not path.exists():
+            missing.append(str(path))
+if missing:
+    raise SystemExit("missing bilingual docs: " + ", ".join(missing))
+print("public docs have zh/en file pairs")
+PY
+```
+
+Check that Markdown links do not expose raw filenames as user-facing titles. This should return no matches for polished public docs:
+
+```bash
+rg -n "\[[^]]+\.md\]\(" docs/technical/zh docs/technical/en
+```
+
+If checking many links, prefer deterministic extraction:
+
+```bash
+rg -n "\]\(([^)]+)\)" docs/technical/zh/<doc>.md
+```
+
+Also run focused stale-term searches derived from the change, for example:
+
+```bash
+rg -n "old label|old route purpose|obsolete provider assumption" docs/technical docs/plans
+```
+
+## Hard Constraints
+
+- A file under `docs/technical/zh/` must not be an English source file copied as a placeholder.
+- Do not leave a Chinese doc with only an English title and English first-screen content.
+- When an English counterpart exists in `docs/technical/en/`, never duplicate it byte-for-byte into `docs/technical/zh/`.
+- Internal links inside `docs/technical/zh/` should point to `docs/technical/zh/...` for Chinese docs, unless intentionally linking to an English-only file.
+- Public technical documents must be registered in `frontend/src/pages/Docs/docs-content.ts` before considering them available in the Docs UI.
+- Public technical documents should have both zh and en files with the same filename, unless intentionally exempted.
+- Markdown link text in public docs should be a readable title, not a raw filename such as `manual.md`.
+- Do not reference PR numbers, issue numbers, or the current conversation.
+- Do not write changelog-style lists like "changed A, changed B, changed C" without the constraints and tradeoffs behind those changes.
+- Keep code snippets concise and relevant.
+
+## Recommended Output
+
+After editing, summarize:
+
+```md
+Updated:
+- docs/technical/zh/example.md — what changed
+
+Verified:
+- no identical en/zh docs
+- no language-less docs/technical links in zh docs
+- public docs are registered in DOCS_METADATA
+- public docs have zh/en file pairs
+- no raw `.md` filenames as public link titles
+```

+name: goal-driven
+description: Run a goal-driven execution loop for very large, long-horizon, rigorously verifiable tasks. Use when the user explicitly wants the lidangzzz/goal-driven method, a master-agent plus worker-agent style workflow, or a persistent loop that keeps working until concrete success criteria are satisfied.
+---
+
+# Goal-Driven
+
+Use this skill when the user wants a strict goal-driven workflow for a hard task with:
+
+- one clear end goal
+- explicit success criteria
+- repeated verification against those criteria
+- continued execution until the criteria are actually met
+
+This skill is adapted from `lidangzzz/goal-driven`, but trimmed for local skill use to avoid bloating context.
+
+## When To Use
+
+Use it for tasks like:
+
+- compilers, interpreters, theorem-like proof work, deep refactors
+- long-running system design or implementation work
+- problems that are expensive and complex, but still objectively testable
+
+Do not use it for:
+
+- vague brainstorming without a success condition
+- short one-shot edits
+- tasks where "done" cannot be evaluated in a meaningful way
+
+## Core Model
+
+The workflow has two roles:
+
+1. Master role
+   Defines the goal, defines the success criteria, audits progress, and decides whether the work is actually complete.
+
+2. Worker role
+   Keeps advancing the task toward the goal. If a result is partial, stalled, or unverifiable, the worker continues.
+
+In Codex, only use actual subagents when the user explicitly asks for delegation or subagent work and the platform supports it. Otherwise emulate the same loop locally: keep working, checkpointing, and re-verifying until the criteria are satisfied.
+
+## Workflow
+
+1. Normalize the task into two blocks:
+   - `Goal`
+   - `Criteria for success`
+
+2. Make the criteria concrete and testable.
+   Good criteria usually include:
+   - required outputs
+   - required validations or tests
+   - edge cases or coverage thresholds
+   - what evidence proves completion
+
+3. Break the work into milestones that can each produce evidence.
+
+4. Execute the next milestone.
+   If subagents are explicitly allowed, the master may delegate bounded worker tasks.
+   If not, do the work locally but keep the master/worker mindset.
+
+5. Whenever work pauses, stalls, or appears complete, audit against the criteria directly.
+   Check artifacts, tests, logs, diffs, metrics, or other real evidence.
+
+6. If the criteria are not met, continue with a specific delta:
+   - what is still missing
+   - what evidence failed
+   - what the next worker pass must improve
+
+7. Stop only when the criteria are met, or when the user explicitly stops the process.
+
+## Operating Rules
+
+- Prefer objective checks over self-reported completion.
+- Prefer deterministic tool evidence over long model summaries: use `rg`, `git diff --stat`, targeted `git diff -- <path>`, tests, builds, linters, `curl`, or database queries when they can prove a criterion.
+- Do not paste large command output into the conversation; summarize the evidence and keep raw output in tool calls.
+- Do not confuse progress with completion.
+- If the worker says "done", verify it.
+- If verification fails, continue from the gap instead of restarting blindly.
+- Keep the goal stable unless the user changes it.
+- Tighten fuzzy criteria before sinking large amounts of effort.
+
+## Recommended Response Shape
+
+When starting a goal-driven task, structure the kickoff like this:
+
+```md
+Goal
+- ...
+
+Criteria for success
+- ...
+
+Current plan
+1. ...
+2. ...
+3. ...
+
+Verification
+- What evidence will prove completion
+```

+3. If verification fails, resume work from the remaining gap.
+4. Repeat until the criteria are met.
+```
+
+## Notes
+
+- Stronger criteria produce better results than stronger rhetoric.
+- Prefer measurable checks such as tests, parity checks, generated artifacts, benchmarks, or reviewable outputs.
+- If the environment does not support subagents, emulate the same loop locally.

+name: release
+description: Use when the user asks to release, bump version, update changelog/version files, or commit/push a repository release for the Planet repo. Determines version bump type from changes, updates all required version-bearing files, updates changelog and version-history, runs minimal validation, then commits, tags, and pushes.
+---
+
+# Release Workflow
+
+Use this skill for release-oriented work in this repository.
+
+## When To Use
+
+- The user asks to `发版`
+- The user asks to bump a version
+- The user asks to update `CHANGELOG`, `version-history`, or version files as part of a release
+- The user asks to commit/push a release or a publishable bugfix/feature bundle
+
+Do not use this skill for ordinary commits that are not being released.
+
+## Versioning Rules
+
+- `feature` -> bump minor and reset patch to `0` (`x.y.z` → `x.(y+1).0`; for example `0.41.2` → `0.42.0`)
+- `bugfix` -> bump `+0.0.1`
+- `docs`, `maintenance`, and `refactor` do not bump by default unless the user explicitly wants a release
+
+When intent is mixed, prefer the user's stated release intent.
+
+## Required Files
+
+Use `git rev-parse --show-toplevel` to get the repo root. All paths are relative to it:
+
+- `VERSION`
+- `frontend/package.json` (`"version"` field)
+- `pyproject.toml` (`version =` field)
+- `uv.lock` (**never edit manually** — regenerate by running `uv lock`)
+- `docs/CHANGELOG.md`
+- `docs/version-history.md`
+
+## Token-Saving Rule
+
+Release work should be driven by deterministic CLI evidence. Prefer compact commands and targeted file reads:
+
+```bash
+git status --short
+git diff --stat HEAD
+git diff --name-only HEAD
+rg -n "version|^## |^Released:|current" VERSION frontend/package.json pyproject.toml docs/CHANGELOG.md docs/version-history.md
+```
+
+Do not inspect full diffs unless deciding whether changed code belongs in the release.
+
+## Workflow
+
+### Step 1 — Environment check
+
+```bash
+git branch --show-current   # must be on dev
+git status --short           # check for unrelated uncommitted changes
+cat VERSION                  # read current version
+```
+
+If not on `dev`, stop and tell the user. Do not proceed.
+
+If unrelated uncommitted changes exist, list them and ask the user whether to include them or stash first.
+
+### Step 2 — Determine release type and next version
+
+- If the user provided an explicit type (`feature` / `bugfix`), use it
+- Otherwise infer from `git diff --stat HEAD`, `git diff --name-only HEAD`, focused diffs for changed code, and recent `git log`
+- Compute the next version:
+  - `feature`: increment minor and reset patch to `0` (e.g. `0.41.2` → `0.42.0`)
+  - `bugfix`: increment patch only (e.g. `0.26.2` → `0.26.3`)
+- **Show the release plan before making any changes:**
+
+```
+Release plan:
+  Type:    bugfix
+  Version: 0.26.2 → 0.26.3
+  Branch:  dev
+  Will update: VERSION, frontend/package.json, pyproject.toml, uv.lock, CHANGELOG.md, version-history.md
+```
+
+### Step 3 — Update version files
+
+Update in order (use Edit for precise replacement, never rewrite whole files):
+
+1. `VERSION` — replace entire content with new version string
+2. `frontend/package.json` — replace `"version": "x.x.x"` line
+3. `pyproject.toml` — replace `version = "x.x.x"` line
+4. Run `uv lock` at repo root to regenerate `uv.lock`
+
+### Step 4 — Update CHANGELOG.md
+
+Insert a new entry at the top of the file:
+
+```markdown
+## x.x.x
+
+Released: YYYY-MM-DD
+
+### Highlights
+
+- ...
+
+### Added / Fixed / Improved
+
+- ... (high-signal items only, max 5)
+
+---
+```
+
+Get today's date with `date +%Y-%m-%d`.
+
+### Step 5 — Update docs/version-history.md
+
+- Update the "current dev version" field in the file header
+- Insert a new row at the top of the timeline table: `| vx.x.x | YYYY-MM-DD | one-line summary |`
+
+### Step 6 — Validate
+
+Run the smallest relevant validation for the changes in scope:
+
+- Python files changed: list changed Python files with `git diff --name-only HEAD -- '*.py'`, then run `python3 -m py_compile <changed_files>`
+- Frontend files changed: list changed frontend files with `git diff --name-only HEAD -- frontend`, then run the project-standard check if available; otherwise skip and say so
+- Version consistency: confirm VERSION, package.json, pyproject.toml, and uv.lock all show the same version
+
+```bash
+cat VERSION
+rg -n "\"version\":|^version =|version = " frontend/package.json pyproject.toml uv.lock
+```
+
+### Step 7 — Pre-commit preview
+
+Show what will be committed:
+
+```bash
+git diff --stat HEAD
+```
+
+Confirm all required files are present and no unexpected files (debug files, `.env`, etc.) are included.
+
+### Step 8 — Commit, tag, and push
+
+```bash
+git add VERSION frontend/package.json pyproject.toml uv.lock docs/CHANGELOG.md docs/version-history.md
+# also stage any code changes included in this release
+git add <code_files>
+
+git commit -m "release: bump version to x.x.x"
+git tag vx.x.x
+git push origin dev
+git push origin vx.x.x
+```
+
+Commit message format is fixed: `release: bump version to x.x.x`
+
+### Step 9 — Completion summary
+
+```
+✓ Version bumped: 0.26.2 → 0.26.3
+✓ CHANGELOG updated
+✓ version-history updated
+✓ uv.lock regenerated
+✓ Validation passed
+✓ commit: release: bump version to 0.26.3
+✓ tag: v0.26.3
+✓ Pushed to origin/dev
+```
+
+## Notes
+
+- `uv.lock` must only be updated by running `uv lock`, never manually
+- The release commit should include only version files + the code for this release — no unrelated changes
+- If `uv` is unavailable in the environment, say so explicitly and remind the user to run it manually

+### 2. 先确认 WSL 内部服务正常
+
+在 WSL 中执行：
+
+```bash
+curl http://localhost:3000
+curl http://localhost:8000/health
+ss -ltnp | grep -E ':3000|:8000'
+```
+
+预期：
+
+- `3000` 返回前端 HTML
+- `8000/health` 返回健康检查 JSON
+- `ss` 中能看到 `0.0.0.0:3000` 和 `0.0.0.0:8000`
+
+如果这一步不通，先不要继续做 Windows 转发。
+
+### 3. 在 Windows 本机验证 localhost 直通
+
+在 Windows PowerShell 中执行：
+
+```powershell
+curl http://localhost:3000
+curl http://localhost:8000/health
+```
+
+在常见的 WSL2 开发环境下，Windows 通常可以直接通过 `localhost` 访问 WSL 中的服务。
+
+### 4. 如果需要让局域网设备访问，再做 Windows 端口转发
+
+注意：下面的命令必须在“以管理员身份运行”的 PowerShell 中执行。
+
+先把 Windows 对外网卡上的 `3000` / `8000` 转发到 Windows 本机 `127.0.0.1`：
+
+```powershell
+netsh interface portproxy delete v4tov4 listenaddress=0.0.0.0 listenport=3000
+netsh interface portproxy delete v4tov4 listenaddress=0.0.0.0 listenport=8000
+
+netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=3000 connectaddress=127.0.0.1 connectport=3000
+netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=8000 connectaddress=127.0.0.1 connectport=8000
+```
+
+再放行 Windows 防火墙：
+
+```powershell
+New-NetFirewallRule -DisplayName "WSL Planet 3000" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 3000
+New-NetFirewallRule -DisplayName "WSL Planet 8000" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 8000
+```
+
+检查转发规则是否生效：
+
+```powershell
+netsh interface portproxy show all
+```
+
+预期能看到：
+
+- `0.0.0.0:3000 -> 127.0.0.1:3000`
+- `0.0.0.0:8000 -> 127.0.0.1:8000`
+
+### 5. 查 Windows 局域网 IP，并让其他设备访问
+
+在 Windows PowerShell 中执行：
+
+```powershell
+ipconfig
+```
+
+找到当前联网网卡的 IPv4 地址，例如 `192.168.8.228`。
+
+局域网其他设备可访问：
+
+- `http://<Windows局域网IP>:3000/earth`
+- `http://<Windows局域网IP>:3000/admin`
+
+例如：
+
+- `http://192.168.8.228:3000/earth`
+
+### 6. 常见现象与判断
+
+- WSL 中 `curl localhost:3000` 能通，但 Windows 访问 `WSL 的局域网 IP:3000` 不通：这是正常现象之一，优先验证 Windows 的 `localhost:3000`
+- Windows `localhost:3000` 能通，但局域网设备访问 `Windows 局域网 IP:3000` 不通：通常缺少 `portproxy` 或防火墙放行
+- `whoami /groups` 中 `S-1-5-32-544` 显示 `deny only`：说明当前 PowerShell 不是提权管理员窗口
+
+### 7. 本项目一次性验证顺序
+
+建议固定按这个顺序验证：
+
+1. WSL 中执行 `curl http://localhost:3000`
+2. WSL 中执行 `curl http://localhost:8000/health`
+3. Windows 中执行 `curl http://localhost:3000`
+4. Windows 中执行 `curl http://localhost:8000/health`
+5. 管理员 PowerShell 配置 `portproxy` 和防火墙
+6. 用手机或其他电脑访问 `http://<Windows局域网IP>:3000/earth`
+
+## 启动容错参数
+
+`planet.sh` 现在为依赖安装、数据库、AI Provider 启动加入了有限次重试，并会在数据库与 `aiprovider` 启动后额外等待 Docker healthcheck。
+
+可通过环境变量临时调整:
+
+```bash
+# 例: 放宽 AI Provider 与数据库在网络抖动下的自愈次数
+AI_PROVIDER_START_MAX_RETRIES=5 \
+AI_PROVIDER_RETRY_INTERVAL=10 \
+DATABASE_START_MAX_RETRIES=5 \
+DATABASE_RETRY_INTERVAL=10 \
+./planet.sh restart
+```
+
+常用参数:
+
+- `DEPENDENCY_INSTALL_MAX_RETRIES` / `DEPENDENCY_INSTALL_RETRY_INTERVAL`: 控制 `uv sync`、`bun install` 的重试次数与间隔，默认 `3` 次、`5` 秒
+- `DATABASE_START_MAX_RETRIES` / `DATABASE_RETRY_INTERVAL`: 控制 `postgres`、`redis` 的启动/重启与健康检查自愈，默认 `3` 次、`5` 秒
+- `AI_PROVIDER_START_MAX_RETRIES` / `AI_PROVIDER_RETRY_INTERVAL`: 控制 `aiprovider` 的构建/启动与容器重启自愈，默认 `3` 次、`5` 秒
+- `BACKEND_MAX_RETRIES`: 控制后端进程启动重试次数，默认 `3`
+- `FRONTEND_MAX_RETRIES`: 控制前端 dev server 启动重试次数，默认 `3`
+- `BACKEND_HEALTH_CHECK_ATTEMPTS` / `BACKEND_HEALTH_CHECK_INTERVAL`: 控制后端 HTTP 健康检查等待次数与间隔，默认 `10` 次、`2` 秒
+- `FRONTEND_HEALTH_CHECK_ATTEMPTS` / `FRONTEND_HEALTH_CHECK_INTERVAL`: 控制前端 HTTP 可访问检查等待次数与间隔，默认 `10` 次、`2` 秒
+- `AI_PROVIDER_HEALTH_CHECK_ATTEMPTS` / `AI_PROVIDER_HEALTH_CHECK_INTERVAL`: 控制 `aiprovider` HTTP 健康检查等待次数与间隔，默认 `10` 次、`2` 秒

+
+官方教程：https://developer.barentswatch.no/docs/tutorial
+
+1. 先打开上面的 BarentsWatch 官方 tutorial，按官方流程登录或注册开发者账号。
+2. 在 Developer access 页面选择 `AIS - API`，不要选择普通的 `BarentsWatch - API`。
+3. 在 `AIS - API` 下创建用于 Planet 的 AIS client。
+4. 创建时记下你设置的 password / client secret。
+5. 回到 My Page 复制完整 `Client ID`。它通常长得像 `your.email@example.com:client-name`。
+6. 回到 Planet 的 `设置 -> 采集器设置 -> BarentsWatch AIS`，填入 `Client ID` 和 `Client Secret`。
+7. 点击 `连接` 验证 token 和 AIS endpoint 是否可访问。
+8. 连接成功后保存凭证。
+
+### 请求规则
+
+- Token 地址：`https://id.barentswatch.no/connect/token`
+- 请求方式：`POST`
+- Content-Type：`application/x-www-form-urlencoded`
+- Body 必须包含：`grant_type=client_credentials`、`client_id`、`client_secret`、`scope=ais`
+- `client_id`、`client_secret`、`scope`、`grant_type` 都要放在 body，不要放在 header。
+- AIS 数据请求使用 header：`Authorization: Bearer <access_token>`
+
+### 常见排查
+
+- `未找到凭证`：确认 `Client ID` 和 `Client Secret` 已填写，或已经写入 `~/.zshrc`。
+- `HTTP 401/403`：通常是选成了普通 `BarentsWatch - API` client、client secret 错误，或 token 请求没有使用 `scope=ais`。
+- `network` 错误：检查本机是否能访问 `id.barentswatch.no` 和 `live.ais.barentswatch.no`。
+- Endpoint 建议保持默认：`https://live.ais.barentswatch.no/v1/latest/combined`。
