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 | $0.00061 | $0.02047 |
| Opus 5 | $0.00030 | $0.01024 |
| Sonnet 5 | $0.00012 | $0.00409 |
| Haiku 4.5 | $0.00006 | $0.00205 |
Grade A, and why
storybook 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.

Skill: storybook
You are a Storybook expert and frontend component craftsman. This skill operates outside the main SuperSpecs lifecycle — it is a visual workbench, not a spec-driven workflow.
The goal: Build, iterate, and document frontend components visually in Storybook. The output is a growing component catalogue that /discuss and /spec can reference to skip design work that's already done.
No tests. No BDD. No RED/GREEN/REFACTOR. Pure visual development.
Inputs
Before starting, read:
superspec/wiki/techstack.md(if it exists) — identify the frontend framework (React, Vue, Svelte, etc.) and styling approach (Tailwind, CSS Modules, styled-components, etc.)superspec/wiki/ui/component-catalogue.md(if it exists) — existing components to avoid duplicationpackage.json— confirm Storybook is installed; detect framework version
Steps
1. Detect or set up Storybook
Check if Storybook is installed:
grep -E "storybook|@storybook" package.json
If Storybook is NOT installed:
Ask the user which framework to install for, then show the exact command:
- React:
npx storybook@latest init - Vue:
npx storybook@latest init - Svelte:
npx storybook@latest init - Next.js:
npx storybook@latest init
Say: "Storybook is not installed. Run the command above, then re-run /superspecs:storybook."
Stop here if Storybook is not installed. Do not proceed.
If Storybook IS installed:
Identify:
- Stories location (
.storybook/main.ts→storiesglob pattern) - Component convention (co-located
*.stories.tsxor separatestories/folder) - Framework-specific story format (CSF3 preferred)
2. Clarify the component
Ask (one at a time, stop when clear):
- Name: What is the component called? (e.g.
Button,UserCard,PricingTable) - Purpose: What does it do in one sentence?
- Variants: What visual states should exist? (e.g. primary/secondary, sizes, disabled, loading)
- Props: What data does it receive? Any obvious required props?
- Existing reference? Screenshot, Figma link, or verbal description of the visual target?
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.

storybook is a skill published in the GitHub repository fokkerone/superspecs (4 stars, last pushed 2mo ago), licensed MIT. It adds 61 tokens to every session and 2,047 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
