What is frontend-componentization?

Guidance for organizing React components, shared interface pieces, page composition, and Storybook examples. Storybook is a tool for viewing and testing interface components separately from the full app.

Use it when extracting components, changing shared interface primitives, composing pages, or adding Storybook surfaces.

It helps decide what should stay local to one page and what is safe to share across the application.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/williamisnotdefined/rubiks-cube-solver

Made for: Cursor.

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	$0.00000	$0.03084
Opus 5.5	$0.00000	$0.01234
Sonnet 5.5	$0.00000	$0.00617
Haiku 4.5	$0.00000	$0.00308

Security

Grade A, and why

frontend-componentization 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.
