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

storybuilder-bible 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.

Load The Series Brainstorm Prompt the user to provide the series brainstorm using the /brainstorm-a-series skill and store it as [braindump].

From the [braindump] locate the [genre_tropes] which we will use later.

Create A Story Bible Given the above [braindump] information and [genre_tropes], I want you to create a pre-writing [story_bible] that has a list of everything the author will need to fully flesh out the characters, worldbuilding, and outline for [book_title].

Here's what you should include:

Characters: Make a complete list of characters, including minor ones, needed for this book. Label these as appropriate with their role in the story (protagonist, antagonist, side character, henchman, comic relief, love interest, etc.) Give a brief explanation of who the character is and their role in the story, but don't give too many details just yet. These should be no more than 1-2 sentences per character. When referencing a group of individuals instead of individual characters, make sure you name 3-5 minor characters who are or would be a part of that group, just so the author has named characters to use when writing scenes with members of those groups in them.

Worldbuilding Info: Make a complete list of all locations, objects, and other worldbuilding information that will be needed for this book. Give a brief explanation of what the worldbuilding element is and its role in the story, but don't give too many details just yet. These should be no more than one sentence per worldbuilding element.

Outline: Make a plan on what will be needed to fully outline this book. Do not actually start outlining the book yet, but give instructions on what will be needed and any suggestions you have.

Characters Given the above [braindump] information, [genre_tropes], and [story_bible], I want you to create a fleshed-out list of all the important characters needed specifically for [book_title]. For each major character, I want you to have the following:

A physical description Their primary role in the story (i.e. protagonist, antagonist, love interest, henchman, etc.) Their most appropriate Myers-Briggs profile, Enneagram, and Clifton Strengths. Their core motivation, what is their heart's desire that is driving them most of the time? A brief explanation of their background before the start of the story An interesting quirk, hobby, or something that makes them unique. This should be something that doesn't necessarily fit with the story, but makes the character more interesting. Dialogue style, how do they talk? Dialogue examples, I want specific examples of dialogue they might give in relaxed, stressful, thoughtful and exciting situations. These dialogue samples do not have to be part of this particular story, they are just to show off the vocal mannerisms of the character.

For minor characters, just have 1-2 sentences for each that gives us a brief understanding of their background, their core desire, and their relationship to the plot. Format your [characters] list using Markdown in the following format:

[book_title] Major Character Name:

Physical Description: [insert details here] Role in Story: [insert details here] Personality Profiles: [insert details here] Core Motivation: [insert details here] Background: [insert details here] Quirk: [insert details here] Dialogue Style: [insert details here] Dialogue Samples: [insert details here] [continue this for all major characters]

Minor Characters:

[MINOR CHARACTER NAME]: [1-2 sentence description here] [MINOR CHARACTER NAME]: [1-2 sentence description here] [continue for all minor characters]

Only include the asked-for character details. Do not add any preamble, commentary, or anything other than what I've asked for above

Worldbuilding Given the above [braindump], [genre_tropes], and [story_bible], I want you to create a fleshed-out list of all important setting and worldbuilding elements needed specifically for [book_title]. I want you to organize all worldbuilding elements into categories. Which categories you use will depend on the genre and what you already have available to you in the outline and dossier, however, some of the categories you MIGHT use include: -High-level Worldbuilding -Setting(s)/Locations -Magic Systems/Technology -Groups/Races -Gods/Dieties -Geography/Nature -Population/Politics -Culture -History/Lore -Religion/Beliefs -Languages
