rubiks-cube-solver: Skill for Claude Code

.agents/skills/frontend-state-management/SKILL.md

frontend-state-management is a skill for Claude Code, Codex from williamisnotdefined/rubiks-cube-solver. It costs 22 tokens per session (2,869 once invoked), scanned A, original, MIT.

A set of rules for managing React state, hooks, stores, asynchronous work, and synchronization with visualizations. State is the data an interface remembers, while asynchronous work finishes later, such as a request or calculation.

In plain words
What is it for?
Use it when changing React state or hooks, shared stores, asynchronous workflows, or synchronization between application data and visualizations.
Why use it?
It helps assign each piece of state to the right owner and define what happens when work is reset, cancelled, or returns late.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is williamisnotdefined/rubiks-cube-solver's own configuration. It tells Claude Code and Codex how to work on rubiks-cube-solver itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything rubiks-cube-solver configures →

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

frontend-state-management 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 9d 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.

Frontend State Management

Use for React state, custom hooks, stores, async workflow state, and visualization synchronization.

Read First

  • ai/rules/frontend-rules.md
  • ai/rules/frontend-state-rules.md
  • ai/rules/frontend-quality-rules.md
  • ai/architecture/frontend-visualization.md

Workflow

  • Classify the state and assign its nearest owner before moving it.
  • Keep server state in React Query, scoped shared client state in existing Zustand stores only when needed, and imperative rendering details in refs/hooks.
  • Define reset, cancellation, and stale-response behavior at the owner.
  • Verify the changed workflow and web build.

Referenced Context

Reference: ai/rules/frontend-rules.md

Frontend Rules

Boundaries

  • Keep solving, notation semantics, puzzle validity, and replay verification in Rust. React renders and coordinates typed product workflows.
  • Keep HTTP mechanics and normalization in apps/web/src/api; UI consumes domain hooks/adapters.
  • Typed scan-session contracts MAY contain reviewed stickers, confidence, and manual overrides. Notation solve UI MUST NOT expose facelet, Kociemba, or raw cube-state inputs.
  • Keep API load, form, page workflow, solve result, scanner review, and visualization playback state separately owned unless a focused page owner coordinates them.
  • Use the active @rubiks-cube-solver/rubiks-cube package as a visualization adapter, never as canonical solver state.

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.
