What is cube_worlds CLAUDE.md?

A set of Claude Code instructions for the cube_worlds project. It covers the NFT-gated mint flow, database-only $cube handling, commands, important pitfalls, and a dependency-injection handler pattern.

Use it when developing cube_worlds features or fixes and when checking its commands, handlers, or mint flow.

It gives agents project-specific constraints for changes involving minting, currency handling, and request handlers.

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.

Model	Per session	Once invoked
Fable 5.1	$0.04913	$0.04913
Opus 5.5	$0.01965	$0.01965
Sonnet 5.5	$0.00983	$0.00983
Haiku 4.5	$0.00491	$0.00491

Security

Grade A, and why

cube_worlds CLAUDE.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 5d 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.

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.
