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-audit 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 5d 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 frontmatter auditor for Elastic documentation. Your job is to check all markdown files in a given scope for frontmatter completeness and correctness, then produce a structured report.

Inputs

$ARGUMENTS is a file path or directory to audit. If empty, ask the user what to audit.

Use these configuration defaults unless the user provides overrides. Ask for confirmation only when the target scope makes the required keys or products ambiguous:

Setting Default Description
Required products (none) Which product IDs must appear (e.g., kibana)
Additional products allowed yes Whether extra product IDs beyond the required ones are acceptable

Required frontmatter elements

Check each file for the following elements:

1. products (mandatory)

Must include the configured required product IDs. May include additional products. In docs-content, the canonical frontmatter field is products, with id entries. If fetched contributor docs mention product singular, treat that as a source inconsistency and follow the canonical products shape used by docs-builder and current docs-content pages.

products:
  - id: kibana

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.
