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.

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 | $0.02456 | $0.02456 |
| Opus 5 | $0.01228 | $0.01228 |
| Sonnet 5 | $0.00491 | $0.00491 |
| Haiku 4.5 | $0.00246 | $0.00246 |
Grade A, and why
rubiks-cube-solver frontend-form-validation.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 4d 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 Form Validation
Use for solve controls, inputs, local limits, scanner review controls, and form submission behavior.
Read First
ai/rules/frontend-rules.mdai/rules/frontend-form-rules.mdai/rules/frontend-quality-rules.mdai/architecture/api-boundary.md
Workflow
- Separate lightweight UX validation from API/engine semantics.
- Choose local state or existing RHF/Zod usage based on the actual form, not a mandatory setup.
- Keep notation forms raw-state-free and scan corrections inside typed scan sessions.
- Verify accessible errors, blocked invalid requests, API outcomes, and relevant E2E behavior.
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-cubepackage as a visualization adapter, never as canonical solver state.
Web Runtime And Locales
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.

rubiks-cube-solver frontend-form-validation.instructions.md is an instructions file published in the GitHub repository williamisnotdefined/rubiks-cube-solver (4 stars, last pushed 11d ago), licensed MIT. It adds 2,456 tokens to every session, about $0.0123 per session on Opus 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.
