Agent Kit · Concept drafts · Independent · Not Southwest Gas files

What agent-legible Southwest Gas would ship: four files, drafted.

Today swgas.com/llms.txt is a 404, every .well-known/ agent path is a 404, and the sitemap's 7,049 URLs are all relative. These drafts close that loop. They are ready to hand to the Southwest Gas web team; EcoWealth runs the verified-completion tools behind them.

Concept drafts only. None of these files exist on swgas.com; EcoWealth drafted them independently as a demonstration. Endpoints under vealth.net are EcoWealth's and live; endpoints under swgas.com are illustrative. Not affiliated with or endorsed by Southwest Gas.

1 · llms.txt: the front door for AI readers

swgas.com/llms.txt (draft)
# Southwest Gas Corporation
# Natural gas to 2.28M customers across Arizona, Nevada, California: 34,000+ mi of mains + service lines.

## Safety & leak reporting
- Smell gas? Report a leak: /en/safety (call 911 + Southwest Gas)
- Pipeline safety & damage prevention (811): /en/safety/pipeline-safety
- Verified field-work receipts (concept, powered by EWP): /safety/receipts

## Programs & field work
- Customer-Owned Yard Line (COYL) replacement: /en/coyl
- Integrity management & modernization: /en/pipeline-integrity
- Verified completion history for contractors (concept): /contractors/verified-history

## Commitments (machine-readable)
- Sustainability & RNG: /en/sustainability, RNG procurement, methane reduction
- Structured data: JSON-LD on all commitment pages (Organization,
  Dataset for emissions metrics, Service for COYL / leak survey)

## Agent endpoints
- Agent card: /.well-known/agent-card.json
- MCP tools: /agent/tools.json
- Verification rail (EcoWealth EWP, Base mainnet): 0x76c17C51336BE7B39F5164802e08b9811477A14B
One file, ~28 lines, makes the leak-report door, the COYL program, and the sustainability commitments discoverable to every AI reader. (Fix the sitemap to absolute URLs in the same pass.)

2 · .well-known/agent-card.json: who agents are talking to

swgas.com/.well-known/agent-card.json (draft, A2A-style)
{
  "name": "Southwest Gas: Verified Field-Work Concierge (concept)",
  "description": "Answers safety, leak-report, program, and sustainability questions with citations; verifies field-work completion receipts on Base.",
  "provider": { "organization": "Southwest Gas Corporation", "verification_rail": "EcoWealth EWP" },
  "capabilities": ["leak-report-guidance", "verify-field-completion",
    "coyl-program-lookup", "emissions-metric-lookup", "contractor-verified-history"],
  "payments": { "scheme": "x402/eip-3009 (USDC, Base)",
    "discovery": "https://vealth.net/.well-known/x402" },
  "contract": "base:0x76c17C51336BE7B39F5164802e08b9811477A14B"
}
Identity + capability + payment discovery in one JSON: what any A2A/MCP client looks for first. (Southwest Gas has no agent card today.)

3 · agent/tools.json: the MCP tool surface

swgas.com/agent/tools.json (draft, MCP schemas, verification tools run on EcoWealth's live rail)
[
  { "name": "author_safety_gated_packet",
    // Draft a field task packet (leak survey, COYL replace, excavation check);
    // REJECTED unless the machine hazard gate passes. Live today: work-packet, $0.10 x402.
    "input": { "place": "string", "task": "string", "hazards": "string[]" } },

  { "name": "verify_field_completion",
    // Deterministic verdict on a proof bundle (photos, GPS, signatures).
    // Live today: work-proof-check, $0.01 x402.
    "input": { "workId": "string", "proofBundle": "object" } },

  { "name": "get_contractor_verified_history",
    // Chain-backed completion receipts for a trade partner or crew — the living
    // companion to internal completion PDFs. (Concept lane.)
    "input": { "partnerId": "string", "since": "date" } },

  { "name": "get_emissions_receipts",
    // RNG / methane-reduction outcomes as receipts (with tCO2e mapping + retirement
    // lane), not PDF claims. Live mapping today: work-tco2e, $0.005 x402. (Concept.)
    "input": { "project": "string", "metric": "enum[methane,rng,tco2e]" } }
]
Two of four tools are running now on EcoWealth's board (renamed); two are the utility-shaped concept lanes a pilot would light up.

4 · The concierge persona

agent/concierge.md (draft)
You are the Southwest Gas Verified Field-Work Concierge (concept).
Voice: calm, safety-first, specific, cited, a utility that puts safety first.

Rules:
1. A suspected gas leak is ALWAYS an emergency: instruct to leave + call 911
   and Southwest Gas immediately, before anything else. Never troubleshoot a leak.
2. "Was it done?" is answered ONLY with a verifiable receipt
   (packet -> proof -> settlement on Base) or the honest words "unverified".
3. Program questions (COYL, integrity, RNG) cite the published page or the
   regulatory filing, never vibes.
4. Never speak for Southwest Gas beyond its published pages.
5. Pay-per-call tools settle over x402 (USDC on Base); reads are free.
Rule 1 keeps safety paramount; rule 2 encodes the whole thesis: advice cites, verification is a receipt.

Try the live half right now

The verification tools behind this kit are not mockups: the building-agent golden path walks an AI agent keylessly through discover → pay → packet → proof → settle on EcoWealth's live board, and curl https://vealth.net/.well-known/x402 returns the priced tool menu today. A runnable, dry-run-default client is at vealth.net/recipes.html.
