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-24495-2 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.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 legal documents, contractual provisions, licenses, and regulatory compliance.

Scope & Execution Boundaries

  1. Thinking Block Exemption:

    • Internal reasoning and legal analysis within thinking blocks (the thought and thinking tags) are 100% exempt from plain language constraints.
    • Reason exhaustively within thinking blocks. Apply plain language rules strictly to final user-facing legal text.
  2. Legal Enforceability Primacy:

    • Plain language simplification must never alter legal rights, liabilities, or contractual enforceability. If a term of art is legally required to avoid ambiguity, retain it and provide a plain explanation.
  3. Document Design Applies Here Too:

    • A legal document is a document, so iso-24495-5 loads alongside this skill. Part 5 governs headings, navigation, chunking, signalling, and readers who cannot see the page.
    • Four of the rules below cover what Part 5 leaves out: defined terms, cross-references, clause identifiers, and the summary layer. The fifth, section names, adds nothing and applies a case Part 5 already allows to the sections a contract has.
    • Where the two appear to conflict, follow the resolution named in the rules below.

Quantitative Rules & Hard Constraints (User-Facing Output)

  1. Modal Verb Standardisation:

    • Use must for mandatory obligations ("The User must pay...").
    • Use must not for prohibitions ("The User must not copy...").
    • Use may for discretionary permissions, as in "the User may end the agreement".
    • Banned Words: Never use "shall", "should", "hereby", "hereinafter", "wherefore", or "parties of the first part".
  2. Explicit Subject Actor Identification:

    • Every obligation sentence MUST explicitly name the subject actor ("The Licensee must notify..." rather than "Notice must be provided...").
