debug-physics

debug-physics is a skill for Claude Code, Codex from AgibotTech/genie_sim. It costs 166 tokens per session (2,421 once invoked), scanned C, original, no licence file.

A guide for finding and diagnosing incorrect behaviour in Genie Sim's robot and scene physics, such as unstable robots, bad contacts, drifting joints, or incorrect mesh and physics settings.

In plain words
What is it for?
Use it when robots move incorrectly, objects pass through each other, cloth becomes unstable, or the simulator shows the wrong mesh or physics backend.
Why use it?
It helps identify whether a simulation problem comes from the scene, robot model, collision setup, limits, or selected physics system.

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 C, and why

debug-physics scanned grade C with 1 finding 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 1mo 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
