One example from this skill

This is the skill's own text, not a summary of it. It runs: that is what verifying means here.

import assert from 'node:assert/strict'
import { Low, Memory } from 'lowdb'

const db = new Low(new Memory(), { posts: [] as string[] })

await db.read()
await db.update(({ posts }) => posts.push('hello'))

assert.deepEqual(db.data, { posts: ['hello'] })

What it did in the sandbox

Verifying this skill meant installing the package and running code against it with no route out. This is what happened, quoted from the run. The full ledger lists every package examined, including the ones that never became a skill.

• prepare: husky install the package
