iso-24495-5

iso-24495-5 is a skill for Codex from GaZmagik/iso-24495. It costs 55 tokens per session (3,147 once invoked), scanned A, original, MIT.

Provisional guidance for arranging complex documents so readers can find information and understand the document's structure. It is based on the draft ISO 24495-5 standard, which has not yet been published.

In plain words
What is it for?
Use it when structuring reports, specifications, guides, contracts, or long technical and health documents for easier reading and navigation.
Why use it?
It addresses documents that are difficult to scan or navigate because headings, layout, and navigation do not clearly show how the information is organised.

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

iso-24495-5 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 12d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (tests/repository-conventions.test.ts, tests/skill-frontmatter.test.ts, tests/templates.test.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

ISO/WD 24495-5 - Plain Language (Document Design) [PROVISIONAL DRAFT]

Provisional status: ISO 24495-5 is a Working Draft (ISO/WD 24495-5) and is not yet published. This skill is original guidance based on the draft's public scope and established information design practice. It does not reproduce ISO text. Expect revision when the standard is published.

Sources: several rules here paraphrase the Document design pattern library, version 0.6, June 2025. That library is by Waller, van der Waarde, Schriver, Slabbert, Cheek and Linsky, for the International Plain Language Federation. The wording in this skill is ours, and no substantial wording is copied from it. Read the Document design pattern library at the International Plain Language Federation for the original.

Extends ISO 24495-1:2023 for the structural design of complex documents: reports, specifications, guides, contracts presented as documents, and long-form technical or health information. Design works together with linguistic cues to help readers find and navigate a document's structure and content.

Design for readers who are not looking at the page. The intended readers include everyone who uses the document. Some see it, some hear it through a screen reader, and some read it by touch.

A listener has no visual hierarchy. Their structure is the heading tree, the link text and the reading order. Every rule below is written to hold when the document is heard.

Scope & Execution Boundaries

  1. Thinking Block Exemption:

    • Internal layout planning and structural reasoning within thinking blocks (<thought>, <thinking>) are 100% exempt from these constraints.
    • Plan freely within thinking blocks. Apply document design rules strictly to final user-facing documents.
  2. Design as Engineering, Not Decoration:

    • Base every design decision on a documented reader need (finding, navigating, comparing, acting). Never add visual elements for aesthetic effect alone.

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.
