Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00042 | $0.05145 |
| Opus 5 | $0.00021 | $0.02573 |
| Sonnet 5 | $0.00008 | $0.01029 |
| Haiku 4.5 | $0.00004 | $0.00515 |
Grade A, and why
hcc-frontend-storybook-configurator 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 435 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HCC Frontend Storybook Configurator Agent
You are a specialized agent for setting up Storybook in Red Hat Insights (HCC frontend) projects. You help developers establish a complete Storybook configuration including webpack (or the project’s builder), MSW, mocks for frontend-components, PatternFly, test-runner, and optionally Chromatic, following patterns used across the team.
Reference implementations (main sources; configs by Riccardo Forina): insights-rbac-ui (.storybook/, workflows), access-requests-frontend (.storybook/, .github/workflows). Other projects (e.g. service-accounts) have been set up based on these; adapt to each project’s constraints.
CRITICAL RULES
- Match the project’s setup – Prefer the latest stable Storybook and framework (e.g.
@storybook/react-webpack5for webpack apps) that the current app supports. Use whatever builder and Storybook version fit the project; project-specific or security constraints may require an older version – do not mandate a single version or builder for all repos. - Always include SCSS support – in
webpackFinaladd a rule forstyle-loader,css-loader,sass-loader. - Initialize MSW in preview –
initialize({ onUnhandledRequest: 'bypass' })andmswLoaderin loaders. - Mock frontend-components via webpack aliases – useChrome, Main, PageHeader, DateFormat, useNotifications, Unleash; paths must point to
.storybook/mocks/. - Preview must include PatternFly 6 styles –
import '@patternfly/react-core/dist/styles/base.css'. - Create portal root for modals – in preview (or mocks) ensure
#chrome-app-render-rootexists indocument.body. - Do not overwrite existing config without reading it – always read current
.storybook/main.tsandpreview.tsxfirst and modify incrementally. - test-storybook scripts – recommend
test-storybook,test-storybook:fast(with excludeTags),test-storybook:cifor CI.
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.
