What it tells the agent
The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

Questions
What does the Siwa skill do?
Bankr Skills equip builders with plug-and-play tools to build more powerful agents.
Is Siwa safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can Siwa access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
Which assistants does Siwa work with?
Its documentation mentions 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 (4029e336cef5), read on 2026-10-09. The repository is watched, and a new audit runs when it changes — this is the first audit.
