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:
- research current pricing and promotion evidence using the host's available web/search tools;
- verify region, buyer identity, payment, invoice/tax and service-policy constraints;
- normalize viable offers to a comparable 12-month cost;
- call the deterministic
ai_saas_deal_rank tool;
- 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, sourceTypecurrency, billingPeriod, billingMonthspriceBeforeDiscount, priceAfterDiscountdiscountPercent, fixedDiscounttaxRatePercent, fees / annualFeesfxRateToTargetregionStatus, identityStatus, paymentStatus, invoiceStatus, policyStatusverifiedAt
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.
