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

simple-english 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 today.

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.

The opening of the file, as written. The whole thing — 346 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Simple English

HARD GATE — Do NOT deliver technical text without classifying it first as procedural or descriptive. Every sentence limit and verb form depends on this choice.

HARD GATE — Do NOT change code, identifiers, CLI flags, file paths, or quoted error messages. Leave them exact.

HARD GATE — Do NOT claim STE compliance. State that final approval rests with the writer.

Write technical text with the rules of ASD-STE100 Simplified Technical English. STE removes long sentences, synonym rotation, and decorative clauses so a tired reader cannot misread an instruction.

Your task

When asked to write or rewrite technical text, do these steps in order:

  1. Select mode (Pragmatic default for docs/READMEs; Strict when user requests full STE/compliance).
  2. Classify each passage as procedural or descriptive.
  3. Fix vocabulary before drafting (pick one verb/noun per concept).
  4. Apply core limits and rules from REFERENCE.md.
  5. Run mandatory self-check before delivery.
  6. Leave code, identifiers, and quoted errors untouched.

When asked to CHECK text, report each violation with rule number, offending text, and compliant rewrite.

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.
