What it can do

Tool inventory

Tools (4)

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢list_offers

Use this first to compare Zinvyl's six fixed-scope offers. Returns each offer's price, delivery window, required inputs, exclusions, and direct intake URL; use get_acceptance_tests only after selecting an offer.

Input Schema

{
  "type": "object",
  "properties": {},
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}
🟢qualify_task(summary)

Use when a buyer's sanitized problem is not yet mapped to an offer. Returns one fixed offer ID, a broader-service route, or a scope-reduction decision; it performs no diagnosis and creates no order.

Input Schema

{
  "type": "object",
  "properties": {
    "summary": {
      "type": "string",
      "minLength": 20,
      "maxLength": 3000,
      "description": "Sanitized expected-versus-actual outcome. Do not include credentials, tokens, personal data, or production secrets."
    }
  },
  "required": [
    "summary"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}
🟢get_acceptance_tests(offer_id)

Use after list_offers or qualify_task identifies an offer. Returns the exact delivery acceptance tests, exclusions, and evidence boundaries that limit what Zinvyl may claim for that offer.

Input Schema

{
  "type": "object",
  "properties": {
    "offer_id": {
      "type": "string",
      "enum": [
        "zinvyl.venture.evidence-brief.v1",
        "zinvyl.venture.prototype-scope.v1",
        "zinvyl.freight.workflow-audit.v1",
        "zinvyl.api.workflow-failure-rescue.v1",
        "zinvyl.api.failure-triage.v1",
        "zinvyl.freight.full-workflow-audit.v1"
      ],
      "description": "Exact published offer ID returned by list_offers or qualify_task, including zinvyl.freight.workflow-audit.v1, zinvyl.freight.full-workflow-audit.v1, zinvyl.api.failure-triage.v1, and zinvyl.api.workflow-failure-rescue.v1."
    }
  },
  "required": [
    "offer_id"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema"
}
🟢prepare_purchase_route(offer_id, human_authorized_to_fund)

Use only after selecting an offer and confirming explicit purchasing authority. Returns the purchase-intent schema and payment-route API endpoint; it does not create, fund, verify, or start an order.

Input Schema

{
  "type": "object",
  "properties": {
    "offer_id": {
      "type": "string",
      "enum": [
        "zinvyl.venture.evidence-brief.v1",
        "zinvyl.venture.prototype-scope.v1",
        "zinvyl.freight.workflow-audit.v1",
        "zinvyl.api.workflow-failure-rescue.v1",
        "zinvyl.api.failure-triage.v1",
        "zinvyl.freight.full-workflow-audit.v1"
      ],
      "description": "Exact published offer ID returned by list_offers or qualify_task, including zinvyl.freight.workflow-audit.v1, zinvyl.freight.full-workflow-audit.v1, zinvyl.api.failure-triage.v1, and zinvyl.api.workflow-failure-rescue.v1."
    },
    "human_authorized_to_fund": {
      "type": "boolean",
      "description": "True only when an authorized representative approved the request or an authorized purchasing agent is acting within explicit delegated authority for this offer, amount, and material limits."
