Code audit
No independent code audit of this skill yet. Commission one (US$ 29 per version; the result is published whatever it says).
Adoption (downloads relative to the registry, 7-day velocity, installs), maturity (age, release cadence, stars, author portfolio), inherited payment trust (every host or wallet the skill's instructions pay is looked up in the x402 service trust index; paying a rated service inherits its tier, an unknown hard-coded wallet is flagged) and hygiene (registry moderation verdict, license, declared setup, origin). Flags cap the tier, they never add to it. Trust line at BBB. Rating as of 2026-10-13.
