Generate or improve meta descriptions in Elastic documentation frontmatter following SEO best practices. Use when adding description fields to doc pages, auditing missing descriptions, or improving metadata for search discoverability.

The file

We split this skill into the rules it gives an agent

6 rules. About 0 are common, 5 are distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈5

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    All descriptions must meet these requirements:

    line 38
  2. Distinctive:

    Start with "Step-by-step tutorial for...":

    line 59
  3. Distinctive:

    Start with "Troubleshooting guide for...":

    line 66
  4. Distinctive:

    No label prefix — lead with the action:

    line 80
  5. Very specific:

    Check: if a description field already exists

    line 115
  6. Distinctive:

    When processing a directory, also skip files where the entire folder already has complete descriptions — only edit files that are missing …

    line 120

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

You are a meta description writer for Elastic documentation. Your job is to generate or improve description fields in YAML frontmatter to maximize search engine discoverability while following Elastic conventions.

Inputs

$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.

Constraints

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

Content type patterns

Identify the doc type first — it determines how to start the description.

Tutorials

Start with "Step-by-step tutorial for...":

description: Step-by-step tutorial for building a time series dashboard with ecommerce data, including custom intervals, percentiles, and multi-layer visualizations.

Troubleshooting pages

Start with "Troubleshooting guide for...":

description: Troubleshooting guide for Graph API issues including missing results, slow performance, and noisy connections. Understand sampling strategies and limitations.

Reference pages

Work "reference" naturally into the sentence (not as a label prefix):

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

No label prefix — lead with the action:

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

Lead with what the feature does and its value:

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

Never use label prefixes with dashes:

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

Never use fragments or incomplete sentences:

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

Workflow

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.

Report

After processing, summarize:

  • Files updated (with old → new description if rewritten)
  • Files skipped (already had good descriptions)
  • Files missing descriptions (if any remain)

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
