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 | $0.03303 | $0.03303 |
| Opus 5.5 | $0.01321 | $0.01321 |
| Sonnet 5.5 | $0.00661 | $0.00661 |
| Haiku 4.5 | $0.00330 | $0.00330 |
Grade A, and why
rubiks-cube-solver rust-module-refactor.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 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.

Rust Module Refactor
Use this skill when splitting large Rust files, changing mod.rs facades, moving tests, tightening visibility, or improving Rust module boundaries without changing behavior.
Goal
Make Rust code easier to read and maintain by extracting concrete responsibilities while preserving public API, solver behavior, artifact compatibility, and verification coverage.

- Use
cube-enginewhen the refactor touches cube state, moves, notation, facelets, or validation. - Use
solver-searchwhen the refactor touches search, heuristics, pruning tables, or two-phase internals. - Use
api-boundarywhen the refactor touches Axum routes, request/response structs, or frontend-facing status contracts.
Workflow
- Identify the current public API and preserve it with facade modules and
pub usebefore moving implementation details. - Split one responsibility at a time: errors, config, result types, parsing, conversion, dispatch, table IO, search traversal, ordering, or tests.
- Prefer private modules and
pub(crate)exports unless an existing caller needs the item. - Keep mechanical moves separate from algorithm, heuristic, format, or contract changes.
- Move tests only when the new location makes the behavior owner clearer.
- Run targeted tests after each module family, then broader crate tests after a larger boundary is stable.
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.
