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 | $0.00057 | $0.01536 |
| Opus 5.5 | $0.00023 | $0.00614 |
| Sonnet 5.5 | $0.00011 | $0.00307 |
| Haiku 4.5 | $0.00006 | $0.00154 |
Grade A, and why
story-ideator 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 1mo 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.

The opening of the file, as written. The whole thing — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Story Ideator Skill
Generate original storylines using an established universe bible. The goal is authentic stories that feel like they belong in the universe while being completely new.
Core Principle: Originality Over Imitation
NEVER:
- Reuse plot structures from analyzed source books
- Copy specific scenes, events, or mysteries
- Recreate villain archetypes with minor changes
- Mirror chapter-by-chapter progression patterns
ALWAYS:
- Use only ELEMENTS (characters, locations, tone) from bible
- Generate plots through COMBINATORIAL techniques
- Verify originality against known source plots
- Create NEW mysteries, conflicts, and resolutions
Input Requirements
Before ideation, verify these files exist:
bible/style.md- Writing constraintsbible/structure.md- Narrative arc patternsbible/characters/*.md- Character profilesbible/universe/*.md- Location files
If analysis/output/*/structure.md files exist, load them for anti-plagiarism checks.
Ideation Workflow
Phase 1: Load Universe Context
Read and extract from bible:
-
Characters: List all from
bible/characters/, extract:- Name, core traits, usual role in stories
- Relationships between characters
- Capabilities and limitations
-
Locations: List all from
bible/universe/, extract:- Name, atmosphere, typical story function
- Connections between locations
-
Structure constraints: From
bible/structure.md:- Expected chapter count/length
- Arc patterns, pacing expectations
- Genre-specific mechanics (mystery, adventure, etc.)
-
Style constraints: From
bible/style.md:- Tone, vocabulary, forbidden elements
- POV, tense, target audience
Output: Brief synthesis in .work/universe-context.md
Phase 2: Brainstorm via Collision Techniques
Generate 10-15 story seeds using these methods. Apply them to the SPECIFIC characters and locations found in Phase 1:
A. What-If Inversion Take a character's usual role and invert it:
- "What if [leader character] had to follow instead of lead?"
- "What if [protector character] needed protection?"
- "What if [cautious character] had to take the biggest risk?"
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
