EBGeometry: Instructions file for Claude Code

CLAUDE.md

EBGeometry CLAUDE.md is an instructions file for Claude Code from rmrsk/EBGeometry. It costs 15,233 tokens per session, scanned D, original, GPL-3.0.

Repository instructions for EBGeometry that cover the project description, cloning it, compiling it, and directly running its compiler. The available details do not explain the geometry features themselves.

In plain words
What is it for?
Use them when setting up EBGeometry, building it, or invoking its compiler directly.
Why use it?
They provide the documented starting points for working with the codebase without claiming unsupported functionality.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is rmrsk/EBGeometry's own configuration. It tells Claude Code how to work on EBGeometry itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything EBGeometry configures →

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.

Security

Grade D, and why

EBGeometry CLAUDE.md scanned grade D with 2 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 today.

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.

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.
