## Sample excerpt

# Buyer Trust Score Builder

Seller reputation is common; buyer trust scoring is rarer and useful for support prioritization and high-value gates. Features stick to confirmed behavior, not social media. Public UX shows buckets, not stalker-ready wallet dossiers.

When to use: skill markets, escrow markets, multi-agent buyers.

**Price:** $6.99 USDC on Base via x402 unlock.

**Standards:** x402 payments · ERC-7857 sealed skill model · agent-swarm ready.

Operator notes for Buyer Trust Score Builder: treat this as a capability pack you wire into real tools—not a certification or hosted SaaS. Pair it with free evaluation at /skills/buyer-trust-score-builder/outline.json before paying. Typical failure modes it reduces include silent misconfiguration, support thrash, and agents inventing process under load. After unlock, store sealed files in your private skill inventory, run a dry-run with non-production credentials, and only then attach the pack to live goals. Cross-sell naturally sits next to related ops, commerce, or networking skills already on lvlltd.com so agents can compose a ladder instead of a one-off purchase.
