England Works Watch

UK sponsor compliance/change intelligence for AI agents and employer workflows.

This product converts current UK Home Office sponsor guidance into deterministic, evidence-linked change-impact decisions for Skilled Worker sponsors. It is designed for employer HR/People Ops agents, HRIS/payroll/recruitment workflows, sponsor-compliance tooling, and regulated adviser tooling. It is not an individual visa-advice chatbot.

Decision contract

Every supported change returns exactly one of:

  • AFFECTED
  • NOT_AFFECTED
  • REVIEW_REQUIRED
  • INSUFFICIENT_INPUT

Every substantive decision includes rule-pack version, effective date, rationale, official GOV.UK evidence, source version, source locator, and required next action where applicable. Missing critical facts, unsupported routes, contradictory inputs, or non-current source evidence fail closed.

V0.1 scope

Supported events: worker start delay; unauthorised absence; unpaid/reduced-pay absence; salary change; role/occupation change; normal work-location change; stopping sponsorship; sponsor organisation changes; TUPE transfer; merger/takeover.

Route scope is deliberately limited to Skilled Worker + sponsor duties.

Validation gate

  • 10 independent change-impact cases
  • 6 negative controls
  • 5 sponsor-event cases
  • 4 explicit fail-closed cases
  • 25 / 25 current fixture decisions passing

MCP tools

Free: england_works_watch_info, licensing_source_status, list_supported_change_events.

Decision: assess_change_impact, batch_assess_changes (up to 25 events).

Production transport is stateless Streamable HTTP at /mcp.

x402

Base mainnet eip155:8453, USDC, exact scheme, PayAI facilitator. assess_change_impact is $0.02; batch_assess_changes is $0.05. Payment is controlled by EWW_PAYMENT_ENFORCED; when enabled EWW_X402_PAY_TO is mandatory.

The free tools provide scope, supported-event vocabulary and official-source status. Paid tools add a deterministic change decision, evidence-linked rationale, required action/deadline fields, and explicit REVIEW_REQUIRED or INSUFFICIENT_INPUT states. At the x402 boundary, call the paid tool to receive PaymentRequired, sign the accepted Base-USDC authorization buyer-side, then retry the same tool call with payment metadata. The decision is not executed until payment is verified. The public england_works_watch_info tool includes a synthetic example result shape. Never send private keys or seed phrases.

Architecture

Agent structured facts -> MCP/x402 boundary -> source lifecycle gate -> deterministic rule engine -> evidence-linked result -> privacy-minimal analytics

There is no server-side LLM in the decision path.

Safety

Evidence-first sponsor compliance preflight only. Not legal advice, a Home Office decision, or a guarantee of compliance. REVIEW_REQUIRED and INSUFFICIENT_INPUT must never be presented downstream as clearance.
