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 | $0.00024 | $0.03412 |
| Opus 5.5 | $0.00010 | $0.01365 |
| Sonnet 5.5 | $0.00005 | $0.00682 |
| Haiku 4.5 | $0.00002 | $0.00341 |
Grade A, and why
frontend-testing 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 2mo 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.mdai/rules/testing-rules.mdai/rules/frontend-quality-rules.mdai/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-cubepackage 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.

frontend-testing is a skill published in the GitHub repository williamisnotdefined/rubiks-cube-solver (5 stars, last pushed 4d ago), licensed MIT. It adds 24 tokens to every session and 3,412 once invoked, about $0.0001 per session on Opus 5.5. 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.
