Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00040 | $0.01427 |
| Opus 5.5 | $0.00016 | $0.00571 |
| Sonnet 5.5 | $0.00008 | $0.00285 |
| Haiku 4.5 | $0.00004 | $0.00143 |
Grade A, and why
iso-24495-3 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 1mo 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.

ISO 24495-3:2026 - Plain Language (Science and Technical Communication)
Proxy status: These rules are this project's own proxies for the standard's principles, not its text. Following them is never a claim of ISO conformance.
Extends ISO 24495-1:2023 for software architecture, technical documentation, algorithm explanations, code reviews, and scientific analysis.
Scope & Execution Boundaries
-
Thinking Block Exemption:
- Internal architectural analysis, code reasoning, and mental trace blocks (the
thoughtandthinkingtags) are 100% exempt from plain language constraints. - Reason freely within thinking blocks. Apply plain language rules strictly to final user-facing technical text.
- Internal architectural analysis, code reasoning, and mental trace blocks (the
-
Code & Data Preservation Immunity:
- Code blocks, stack traces, abstract syntax tree (AST) dumps, terminal commands, and exact line quotes are completely immune to sentence length and simplification constraints. Never alter, abbreviate, or mangle working code or logs to fit text constraints.
-
Document Design Applies Here Too:
- A technical document is a document, so
iso-24495-5loads alongside this skill. Part 5 governs headings, navigation, chunking, signalling, and readers who cannot see the page. - It loads for a document, not for every explanation. A code review comment and a chat answer are explanations, and the rules below still govern them.
- Where the two appear to conflict, follow the resolution named in the rules below.
- A technical document is a document, so
Quantitative Rules & Hard Constraints (User-Facing Output)
- Progressive Disclosure Ordering:
Structure every technical explanation in these stages, in this order:
- System Purpose: High-level operational intent (1 sentence).
- Architecture & Data Flow: Diagram (Mermaid) or summary table. Rule 4 governs the diagram's text alternative, and Part 5 governs the table. Required where the explanation covers how more than one component relates to another. A single mechanism needs none, and neither does a sequence of steps that an ordered list already presents in order. A diagram nobody needs is the decoration Part 5 forbids.
- Implementation Detail: Concrete code snippet with exact file citations.
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.
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.

iso-24495-3 is a skill published in the GitHub repository GaZmagik/iso-24495 (200 stars, last pushed today), licensed MIT. It adds 40 tokens to every session and 1,427 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
