Questions
What does the Prompt Engineering Expert skill do?
🧠 Curated collection of 1209+ best OpenClaw skills — weekly updated by MyClaw.ai
Is Prompt Engineering Expert safe to install?
No — not without reading the findings first. The audit graded it D (69/100) and found 3 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What can Prompt Engineering Expert access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
Which assistants does Prompt Engineering Expert work with?
Its documentation mentions claude-code and openclaw. That is what the text claims, not a compatibility test we ran.
How current is this page?
The grade is for one exact copy of the source (4f3b4a2a472e), read on 2026-10-08. The repository is watched, and a new audit runs when it changes — this is the first audit.
