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 | $0.02961 | $0.02961 |
| Opus 5.5 | $0.01184 | $0.01184 |
| Sonnet 5.5 | $0.00592 | $0.00592 |
| Haiku 4.5 | $0.00296 | $0.00296 |
Grade A, and why
rubiks-cube-solver solver-search.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.

Solver Search
Use this skill when adding or changing IDA*, generated two-phase search, heuristics, pruning, or pattern database code.
Goal
Add search behavior only on top of correct cube state and move semantics.
Read First
ai/rules/solver-search-rules.mdai/rules/testing-rules.mdai/architecture/project-architecture.mdai/architecture/solver-search.mdai/architecture/cube-engine.mdai/glossary/cube-terms.md
Workflow
- Verify cube move behavior before trusting search results.
- Start with shallow deterministic cases.
- Keep heuristics separate from traversal logic.
- Mark whether each heuristic is admissible.
- Add node/depth metrics for non-trivial algorithms.
Expected Output
- Search returns explicit move sequences and metrics.
- Tests cover solved state and shallow known scrambles.
- No learned or external inference heuristic is introduced without an explicit current product requirement.
Verification
- Run
cargo test -p cube-enginewhen Rust is installed. - Include targeted tests for the changed search module.

Solver Search Rules
Rules for search, heuristics, and pattern database work.
Always
- Keep search algorithms in
crates/cube-engine/src/searchunless a later crate boundary is introduced. - Keep heuristics explicit about admissibility.
- Prefer bounded IDA* and generated two-phase paths after move tables are correct.
- Prune inverse moves and repeated same-axis branches where correctness allows it.
- Measure node counts and depth limits for non-trivial search changes.
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 solver-search.instructions.md is an instructions file published in the GitHub repository williamisnotdefined/rubiks-cube-solver (5 stars, last pushed 4d ago), licensed MIT. It adds 2,961 tokens to every session, about $0.0118 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.
