In plain words
What is it for?
Use it when writing Python for FiftyOne, contributing to its codebase, or building a plugin that integrates with it. The input describes style conventions rather than runtime features.
Why use it?
It helps contributions and plugins match the project's established layout, naming, imports, and documentation style. That makes code easier for the project team to review and maintain.

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.

Opus 5 $0.00019 $0.00476
Sonnet 5 $0.00008 $0.00190
Haiku 4.5 $0.00004 $0.00095

Security

Grade A, and why

fiftyone-code-style 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 10d 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.
