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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00021 | $0.00751 |
| Opus 5 | $0.00010 | $0.00376 |
| Sonnet 5 | $0.00004 | $0.00150 |
| Haiku 4.5 | $0.00002 | $0.00075 |
Grade A, and why
docs-page-frontmatter 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 7d 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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Documentation Page Front Matter
This skill guides writing YAML front matter for mkdocs-material documentation pages. Front matter controls social card generation and page metadata.
Front Matter Format
---
title: "Page Title"
description: "Brief description of the page."
---
Title Guidelines
- Use descriptive titles that provide context
- Include the subject matter (e.g., "LanceDB Configuration" not just "Configuration")
- Keep titles concise but informative
- For API reference pages: "[Subject] API" or "API reference for [Subject]"
- For configuration pages: "[Subject] Configuration"
- For index pages: Use the section name (e.g., "Integrations", "User Guide")
Description Guidelines
DO:
- Briefly summarize what the page covers
- Keep descriptions general and conceptual
- Use simple, direct language
- Focus on the page content, not the subject itself
DON'T:
- Enumerate specific implementation details that may become outdated
- List specific technologies, databases, or tools unless the page is specifically about one
- Prescribe use cases (avoid "for local development", "ideal for production", etc.)
- Use verbose explanations
- Describe what the subject does (describe the page instead)
Examples
Good Descriptions
# API reference page
description: "API reference for DuckDBMetadataStore."
# Configuration page
description: "Configuration options for ClickHouseMetadataStore."
# Concept page
description: "How Metaxy calculates and tracks versions."
# Index page
description: "Available metadata store backends for Metaxy."
# Integration overview
description: "Dagster integration for Metaxy."
# Guide page
description: "Defining dependencies between features."
Bad Descriptions (Avoid These)
# Too verbose, lists specific details
description: "Connect Metaxy with orchestrators like Dagster, databases like ClickHouse and BigQuery, and plugins for SQLModel and SQLAlchemy."
# Prescribes use case
description: "Use DuckDB as a fast embedded analytical database for local development and testing with Metaxy."
# Enumerates implementation details
description: "Configuration options for DuckDBMetadataStore including database path, extensions, and DuckLake settings."
# Describes the subject, not the page
description: "A pluggable metadata layer for ML pipelines that tracks feature versions, dependencies, and data lineage."
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.

docs-page-frontmatter is a skill published in the GitHub repository anam-org/metaxy (119 stars, last pushed 18d ago), licensed Apache-2.0. It adds 21 tokens to every session and 751 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
