AI SaaS Deal Finder for DeepSeek Harness

A host-only DSH plugin that helps users find the cheapest legitimate AI/SaaS purchase option that actually applies to them.

It is designed for region-sensitive purchases: the cheapest advertised coupon is not necessarily usable in the user's country, by their account type, with their payment method, or under the service's current policy.

What it does

When a user asks how to buy an AI/SaaS service more cheaply, the plugin teaches the Harness agent to:

1. research current pricing and promotion evidence using the host's available web/search tools;
2. verify region, buyer identity, payment, invoice/tax and service-policy constraints;
3. normalize viable offers to a comparable 12-month cost;
4. call the deterministic ai_saas_deal_rank tool;
5. return the cheapest verified usable option, with conditional alternatives clearly labeled.

The plugin does not ship a stale coupon database and does not claim a promotion works merely because a search result mentions it.

China-aware behavior

For mainland-China users, the workflow explicitly checks:

• official service availability;
• account and geographic eligibility;
• accepted payment methods;
• invoice/receipt requirements;
• regional restrictions and renewal terms;
• whether a purchase route conflicts with service terms.

It will not recommend fake billing addresses, account trading, VPN/region spoofing, or other policy-circumvention methods.

Tool

ai_saas_deal_rank

Ranks researched candidate offers after applying deterministic eligibility and cost checks.

Each offer can include:

• title, sourceUrl, sourceType
• currency, billingPeriod, billingMonths
• priceBeforeDiscount, priceAfterDiscount
• discountPercent, fixedDiscount
• taxRatePercent, fees / annualFees
• fxRateToTarget
• regionStatus, identityStatus, paymentStatus, invoiceStatus, policyStatus
• verifiedAt

Status values: eligible, ineligible, unknown, or not_required where appropriate.

The tool returns verified, conditional, and excluded groups and ranks usable offers by normalized annual cost.

Install from GitHub
