Inputs

输入

$ARGUMENTS
is a file path or directory. If a directory, process all 
.md
files. If empty, ask the user what to work on.
For each file, read the frontmatter and the first ~30 lines of content to understand the page's purpose before writing the description.
$ARGUMENTS
是文件路径或目录。如果是目录，则处理所有 
.md
文件。如果为空，则询问用户要处理什么。
对于每个文件，在编写描述之前，先读取 frontmatter 和正文的前约 30 行，以了解页面的用途。

Constraints

约束

All descriptions must meet these requirements:
RuleDetail
LengthMaximum 200 characters
ToneAction-oriented, value-focused, factual and impersonal
VoiceNo "you can", "users can", or "this page explains"
SentencesComplete sentences, not fragments or labels
ContextInclude "with [feature/tool]" to establish scope
SubstitutionsPlain text only — no Jinja2 variables (
{{kib}}
, 
{{es}}
) since they aren't parsed in frontmatter
Forbidden words"teaching", "enable", "disable", or condescending/excluding terms
No versionsDon't mention version numbers
No colonsDon't include 
:
after 
description:
— it breaks YAML parsing
UniquenessEach description must be unique to its page
所有描述都必须满足以下要求：
规则详细信息
长度最多 200 个字符
语气以行动为导向、聚焦价值、基于事实且不针对个人
表达方式不使用“you can”、“users can”或“this page explains”
句子使用完整句子，而不是片段或标签
上下文包含“with [feature/tool]”以明确范围
替换项仅使用纯文本——不要使用 Jinja2 变量（
{{kib}}
、
{{es}}
），因为 frontmatter 不会解析这些变量
禁用词“teaching”、“enable”、“disable”，或居高临下及排斥性词语
版本信息不提及版本号
冒号不要在 
description:
后包含 
:
，否则会破坏 YAML 解析
唯一性每条描述都必须与其页面唯一对应

Content type patterns

内容类型模式

Identify the doc type first — it determines how to start the description.
先识别文档类型——这决定描述的开头方式。

Tutorials

教程

Start with "Step-by-step tutorial for...":
yaml
description: Step-by-step tutorial for building a time series dashboard with ecommerce data, including custom intervals, percentiles, and multi-layer visualizations.
以“Step-by-step tutorial for...”开头：
yaml
description: Step-by-step tutorial for building a time series dashboard with ecommerce data, including custom intervals, percentiles, and multi-layer visualizations.

Troubleshooting pages

故障排查页面

Start with "Troubleshooting guide for...":
yaml
description: Troubleshooting guide for Graph API issues including missing results, slow performance, and noisy connections. Understand sampling strategies and limitations.
以“Troubleshooting guide for...”开头：
yaml
description: Troubleshooting guide for Graph API issues including missing results, slow performance, and noisy connections. Understand sampling strategies and limitations.

Reference pages

参考页面

Work "reference" naturally into the sentence (not as a label prefix):
yaml
description: Compare visualization capabilities across Lens, TSVB, aggregation-based editors, Vega, and Timelion. Reference tables list supported chart types, features, and aggregations.
将“reference”自然融入句子中（不要作为标签前缀）：
yaml
description: Compare visualization capabilities across Lens, TSVB, aggregation-based editors, Vega, and Timelion. Reference tables list supported chart types, features, and aggregations.

Standard how-to / procedural pages

标准操作指南或流程页面

No label prefix — lead with the action:
yaml
description: Add interactive filter controls to dashboards with Options lists, Range sliders, and Time sliders. Filter data dynamically and focus on specific segments.
不要添加标签前缀——直接以行动开头：
yaml
description: Add interactive filter controls to dashboards with Options lists, Range sliders, and Time sliders. Filter data dynamically and focus on specific segments.

Overview / explanation pages

概述或说明页面

Lead with what the feature does and its value:
yaml
description: Detect patterns in unstructured logs with Discover's pattern analysis. Categorize log messages, identify common structures, and filter out noise during troubleshooting.
先说明该功能的作用及其价值：
yaml
description: Detect patterns in unstructured logs with Discover's pattern analysis. Categorize log messages, identify common structures, and filter out noise during troubleshooting.

Anti-patterns

反模式

Never use label prefixes with dashes:
yaml
undefined
绝不要使用带短横线的标签前缀：
yaml
undefined

WRONG

WRONG

description: Reference - Compare visualization capabilities... description: Tutorial - Build time series dashboards... description: Guide - Manage dashboards by searching...

**Never use fragments or incomplete sentences:**
```yaml
description: Reference - Compare visualization capabilities... description: Tutorial - Build time series dashboards... description: Guide - Manage dashboards by searching...

**绝不要使用片段或不完整句子：**
```yaml

WRONG

WRONG

description: Dashboard creation and management. description: How to configure alerts.

Workflow

工作流

For each file:
  1. Read the frontmatter and first ~30 lines of body content
  2. Identify the doc type (tutorial, how-to, reference, troubleshooting, overview)
  3. Check if a 
    description
    field already exists
  4. Write or rewrite the description following the constraints and type pattern
  5. Verify length is ≤ 200 characters
  6. Edit the frontmatter to add or update the 
    description
    field
When processing a directory, also skip files where the entire folder already has complete descriptions — only edit files that are missing or have subpar descriptions.
对于每个文件：
  1. 读取 frontmatter 和正文的前约 30 行
  2. 识别文档类型（教程、操作指南、参考、故障排查、概述）
  3. 检查是否已存在 
    description
    字段
  4. 编写或重写描述，并遵循各项约束和类型模式
  5. 验证长度 ≤ 200 个字符
  6. 编辑 frontmatter，添加或更新 
    description
    字段
处理目录时，还要跳过整个文件夹中所有描述均已完整的文件——仅编辑描述缺失或不理想的文件。

Report

报告

After processing, summarize:
  • Files updated (with old → new description if rewritten)
  • Files skipped (already had good descriptions)
  • Files missing descriptions (if any remain)
处理完成后，总结：
  • 已更新的文件（如果重写，则列出旧描述 → 新描述）
  • 已跳过的文件（已有良好描述）
  • 仍缺少描述的文件（如有）
