Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docs-frontmatter-description scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

Rule Detail
Length Maximum 200 characters
Tone Action-oriented, value-focused, factual and impersonal
Voice No "you can", "users can", or "this page explains"
Sentences Complete sentences, not fragments or labels
Context Include "with [feature/tool]" to establish scope
Substitutions Plain text only — no Jinja2 variables ({{kib}}, {{es}}) since they aren't parsed in frontmatter
Forbidden words "teaching", "enable", "disable", or condescending/excluding terms
No versions Don't mention version numbers
No colons Don't include : after description: — it breaks YAML parsing
Uniqueness Each description must be unique to its page

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
