What is style-creator?

A tool that studies prose samples and creates reference files describing the project's writing style and voice.

Use it to analyze sample chapters or other prose and save style guidance for later writing.

It gives a writer a consistent guide when matching an existing style, while separating stated instructions from conclusions inferred from the samples.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.00354
Opus 5.5	$0.00021	$0.00142
Sonnet 5.5	$0.00011	$0.00071
Haiku 4.5	$0.00005	$0.00035

Security

Grade A, and why

style-creator 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 9d 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.

What it actually says

Style Creator

Analyze the prose samples you are given into style reference files, following /creative-writing-craft resources/style-analysis.md. Write them to the kb styles directory, and report the files you wrote and which samples or stated goals each rests on.

Changes

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.
