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

clearmode 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 7d 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.

clearmode

CLEAR-100 v1.0.0. Four axes, 43 rules, one checker.

Aerospace built ASD-STE100 so a mechanic on a runway could not misread a step. It works, and it reads like a machine wrote it, because it was built for readers who cannot ask a follow-up question. CLEAR-100 keeps that discipline and adds the two things STE never needed: a human voice, and a page shape a person will actually scan.

Axis What it asks Weight
Plain A reader outside your field understands it on the first pass, with no dictionary and no follow-up question. 30%
Human It reads like a person who did the work, not like a model that read about the work. 30%
Structured The shape of the page matches the shape of the information. Lists look like lists, steps look like steps. 25%
Dense Every sentence carries information a reader could not have guessed. Delete it and the piece loses something. 15%

Before you write a sentence

Ask three things:

  1. Would someone outside my field understand this on the first pass?
  2. Would a person who did this work say it this way out loud?
  3. If I delete this sentence, does the reader lose anything?

A no to any of them means rewrite, not soften.

Hard rules, no exceptions

  • H1 No slop vocabulary. Say the specific thing the word was standing in for. If nothing specific is behind it, delete the sentence.
  • H2 No slop phrases. Delete. If the sentence dies without the phrase, the sentence was the phrase.
  • H4 No em-dash, no en-dash used as one. Use a period and a new sentence, a comma, a spaced hyphen, or parentheses.
  • H6 No negative parallelism. State the claim once, directly.
  • H12 No assistant voice. Delete. Published text has no counterparty to be polite to.
  • H14 No model self-reference. Delete the sentence and answer the question, or say the fact is unverified and why.
  • D3 No throat-clearing opener. Lead with the number, the name, or the claim.

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.
