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

writing:writing 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 10d 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Writing

Write prose a person reads in a direct, conversational voice. The writing hooks lint saved files and outgoing messages against the Vale styles in styles/Writing/. The text is done when every alert the hook reports on it is fixed.

Voice

Every sentence teaches something new and holds only for this subject. Cut a sentence that restates the obvious or could move unchanged to another person, company, or product, or replace it with something true only of this subject.

  • Prefer substance to filenames or implementation details.
  • Prefer short sentences to compound constructions.

Rules

Structure
  • Use no spaced em dash (—).
  • Write each independent clause as its own sentence. A clause joined by an em dash, semicolon, hyphen, or any connector swapped in for one becomes a sentence break. Keep a semicolon only when the clauses can't stand alone.
  • State the point directly in place of "not just X, but also Y" parallelism.
  • Name a heading's topic in a couple of words: a noun phrase, without verbs or a Topic: clause form. Put the explanation in the body.
Word Choice
  • Use "is" or "are" where "serves as" or "stands as" would go.
  • Write "use X" or "prefer X over Y" in place of "reaching for X".
  • Name what you're examining in place of "dig into" or "dive into".
  • State a claim directly, or name the uncertainty, in place of hedging verbs ("looks like", "appears to", "seems to").
  • Negate the verb with a contraction: "doesn't cost an extra query", "doesn't need a change". A positive term works when it names the state exactly ("a no-op", "unchanged"). Plain statements like "has no tests" and "there is no lock" stay.
  • Say why something matters in place of gravity markers ("load-bearing", "the honest answer", "worth noting/flagging", "the full picture", "the cleanup story"): name what breaks without the dependency, or state the fact plainly.
PR and Review Prose
  • Open a published comment on the substance, without a greeting or a name. Refer to people in third person by their username as written.
  • Use active voice: "Adds X" in PR and review prose, "Add X" in commit subjects, "Added tests covering X" for tests.
  • Describe what the tests cover in place of test counts, pass/fail tallies, or CI status.
  • End a sentence on its content, without a trailing hedge adverb ("regardless.", "nonetheless.").
  • State the positive directly in place of contrast by negation, whether across sentences ("It isn't X. It is Y.") or inline (X, not Y).

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.
