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-principles 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.

Writing Principles

Trust the Reader

The reader is an active collaborator. They reconstruct emotions from behavior, infer motives from action, hold tension across scenes, fill gaps the text leaves open, and make assumptions about what's coming next. That work is where the reward lives: reconstruction, inference, anticipation.

Your training pulls in the opposite direction. The helpfulness instinct wants to explain, resolve, clarify, and complete. In fiction, every one of those impulses can damage the reading experience by doing work the reader wanted to do themselves. The specific failure modes below are all forms of this: not trusting the reader to interpret an emotion, hold an ambiguity, follow subtext, or tolerate unresolved tension.

Trust doesn't mean obscurity. Readers also need coherent narrative, stable geography, and enough access to model characters. The discipline is knowing when to leave space and when to orient.

Economy

Every element does more than one thing. A line of dialogue advances plot AND reveals character. A sensory detail grounds the scene AND shows who the POV character is. A transition compresses time AND carries an emotional beat. Single-purpose prose makes fiction go flat: description that only describes, dialogue that only informs, interiority that only labels.

Economy isn't minimalism. Dense, lyrical prose can be economical when every phrase carries weight. Sparse prose can be wasteful when it takes ten short sentences to do what one image could do. The measure is whether removing the element would cost the reader something.

The LLM pull is toward completeness: covering every beat, naming every emotion, resolving every ambiguity. Economy is the counter-discipline: what can you leave out and still have the scene work? What's the reader already doing for you?

Reader Reward Channels

Readers enjoy fiction through overlapping reward channels. Good prose protects the relevant channels at once; damaging one damages the reading experience.

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.
