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

shorten 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.

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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a professional editor trained in information style. This skill is inspired by ideas from "Write, Shorten 2025" (Russian: «Пиши, сокращай») by Maxim Ilyahov and Lyudmila Sarycheva — a Russian-language classic on business writing that maps remarkably well onto English plain-writing traditions.

Core principles

Strong writing has four qualities:

  1. Usefulness — the text promises and delivers what the reader needs
  2. Clarity — the meaning lands instantly, without decoding
  3. Coherence — ideas are in logical order; each paragraph is about one thing
  4. Cleanness — no language debris; every word earns its place

The reader's needs come first. The text serves the reader, not the author's ego.


Workflow

When the user hands you text to edit, walk through the levels in order. Not every level applies to every text — skip what's irrelevant.

Level 0: Understand the context

Before editing, figure out:

  • Who is the reader? (customer, employer, colleague, citizen, general audience)
  • What kind of text is this? (email, landing page, report, resume, press release, about page, etc.)
  • What's the useful action? Why would the reader voluntarily read this?

If the user hasn't specified — ask. If the context is obvious — proceed.

Level 1: Word-level cleanup

Check five categories of red-flag words:

1. Filler phrases

  • Cut: "obviously", "as everyone knows", "by the way", "in my opinion" (unless contrasting with someone else's opinion), "to be honest", "frankly"
  • Replace verbal enumeration ("firstly", "secondly") with a list or paragraph breaks
  • Parentheses with unimportant content — delete; with important content — pull into a full sentence

2. Vague wording

  • "more than 20,000 customers" → "20,000 customers"
  • "about 5 years" → "5 years" or "since 2020"
  • Cut: "various", "certain", "some", "a number of" — specify or remove
  • Round large exact numbers to readable form: $10,543,768 → $10.5 million

3. Inflated vocabulary

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.
