rubiks-cube-solver frontend-testing.instructions.md

A set of instructions for testing web front ends, including component tests, API-related tests, browser-based end-to-end tests, Storybook checks, and coverage. A front end is the part of an application people see and use.

In plain words
What is it for?
Use it when writing or reviewing Vitest, Testing Library, Storybook, or Playwright tests and when checking test coverage and accessibility-oriented queries.
Why use it?
It provides a consistent way to test user-visible behavior and catch failures such as cancelled requests or recoverable errors.

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.

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

rubiks-cube-solver frontend-testing.instructions.md 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 2d 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 Testing

Use for Vitest, Testing Library, API-domain tests, coverage, Storybook, and Playwright E2E.

Read First

  • ai/rules/frontend-rules.md
  • ai/rules/testing-rules.md
  • ai/rules/frontend-quality-rules.md
  • ai/architecture/web-architecture.md

Workflow

  • Test observable behavior at the narrowest public boundary and place it in the nearest established __tests__ folder.
  • Use accessible queries and shared API/E2E helpers; cover cancellation and recoverable failures where relevant.
  • Keep global statements, branches, functions, and lines thresholds at 90%.
  • Run the targeted test first, then coverage, Storybook, or the relevant E2E split for the changed surface.

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.
