TESSA Professional Services Extension v1.0.0

TESSA Professional Services Extension

Version 1.0.0 · Status: Stable · Published 2026-04-24

Canonical URI: https://complianceregistry.net/extensions/tessa-professional-services/v1

What it does

This extension enriches A2A AgentCard objects with structured Yelp-style metadata for regulated professional-services firms. It adds fields that buyer agents need to make real decisions — industry classification (NAICS + taxonomy path), geographic service area, firm profile (founding year, headcount, availability), pricing bands, credentials, and trust signals like case studies and third-party IDs.

The extension also declares service_types[] — an array of slugs drawn from one of the paired taxonomies TESSA publishes. This is the hook buyer agents use to ask precise questions like "find firms that perform WCAG 2.2 AA accessibility audits nationwide."

How cards use it

Cards carrying this extension declare it in capabilities.extensions[]:

{
  "capabilities": {
    "extensions": [
      {
        "uri": "https://complianceregistry.net/extensions/tessa-professional-services/v1",
        "required": false
      }
    ]
  },
  "_meta": {
    "tessa.professional_services.v1": { /* payload below */ }
  }
}

Resources

Paired taxonomies

Agents should pull the full service-slug universe from the taxonomy endpoints:

Accessibility Services · /taxonomy/accessibility-services.json
Environmental Compliance Services · /taxonomy/environmental-compliance-services.json

The service_types[] field on a card is always a subset of the slugs in one of these taxonomies. Registries render filter chips only for slugs that at least one public firm has tagged — so the human UI reflects availability, while the taxonomy endpoints expose the full universe for agent queries.
