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-artifacts 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 11d 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 — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

writing-artifacts

A durable artifact has readers you will never meet, arriving with zero conversation context, often skimming, sometimes another agent. Write for that reader. This skill is a system to write toward, not a list of things to avoid: supply the right structure and the slop has nowhere to live.

Stance (adopt before writing)

You are a competent colleague showing the reader something you have both, in principle, access to. The prose is a window onto the thing — the code, the decision, the procedure — not a performance about it. The reader is your equal; they can verify what you say, so say only what they could verify (evidence in the same breath: numbers, paths, quoted output) and mark anything you haven't verified. Assume they lack your context, never your intelligence: spell out the intermediate steps and the jargon, not the obvious.

Document layer — give it one job

Before writing, answer in one line: who arrives at this document, and what did they come for? Then give the document that one job (Diátaxis):

  • Learning a skill by doing → tutorial (a lesson; you drive, they follow, it must work).
  • Getting a task done now → how-to (steps to a goal; they're at work, respect that).
  • Looking something up while working → reference (facts, structured for lookup, no digressions).
  • Understanding why, away from the keyboard → explanation (discursive, context, trade-offs).

When one document must serve two jobs (a README usually must), separate the jobs into sections rather than blending sentence-by-sentence — mixed types bleed and serve neither reader. Use the types as a compass, not a filing system; don't scaffold empty sections.

Order the whole document bottom-line-first: purpose and outcome in the first paragraph, general before exceptions, background last. A good README's first paragraph lets most readers stop reading, satisfied.

Paragraph layer

One point per paragraph, stated in the first sentence; the rest is support. In procedures: one action per step, condition before command ("If the build is red, do not deploy" — never the reverse).

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.
