machine-purchase-roi-gate

Machine Purchase ROI Gate: Decide whether an agent should buy one machine service call before any payment. Validate explicit price, fee, failure probability, retry cost, output value, and budget assumptions; calculate expected net value, finite financial ROI, capital at risk, and the maximum rational price; then return buy, defer, or reject with the binding reason. Never access a wallet, sign, pay, or broadcast. Use when an agent needs to run this published AgentPMT workflow with 2 linked tool.

What This Workflow Does

Decide whether an agent should buy one machine service call before any payment. Validate explicit price, fee, failure probability, retry cost, output value, and budget assumptions; calculate expected net value, finite financial ROI, capital at risk, and the maximum rational price; then return buy, defer, or reject with the binding reason. Never access a wallet, sign, pay, or broadcast.

Workflow Process

1. Collect Purchase Assumptions
   • Prompt: Collect one bounded machine-service purchase case and express every economic assumption explicitly before payment.
2. Validate Purchase JSON
   • Tool product: Data Format Validation.
   • Tool skill: ../data-format-validation.
   • ClawHub page: https://clawhub.ai/agentpmt/data-format-validation.
   • skills.sh install: npx skills add AgentPMT/agent-skills --skill data-format-validation.
   • Marketplace: https://www.agentpmt.com/marketplace/data-format-validation.
   • Tool instructions: Validate the canonical JSON from the prior step. Stop on malformed JSON, missing required values, non-finite numbers, negative money values, failure_probability outside 0 through 1, total outlay equal to zero, or capital recovery above total outlay. Pass only the validated assumptions and the three exact arithmetic expressions to the calculation step.
   • Default parameters are configured on this workflow node; use the linked tool skill for schema details.
3. Calculate Expected Return
   • Tool product: Complex Mathematics Engine.
   • Tool skill: ../complex-mathematics-engine.
   • ClawHub page: https://clawhub.ai/agentpmt/complex-mathematics-engine.
   • skills.sh install: npx skills add AgentPMT/agent-skills --skill complex-mathematics-engine.
   • Marketplace: https://www.agentpmt.com/marketplace/complex-mathematics-engine.
   • Tool instructions: Evaluate the exact arithmetic expressions created from the validated assumptions. Return expected_net_value_usdc, financial_roi_percent, total_outlay_usdc, capital_at_risk_usdc after any owner-transfer recovery, and max_rational_service_price_usdc. Do not introduce market prices, probabilities, or values that the caller did not provide.
   • Default parameters are configured on this workflow node; use the linked tool skill for schema details.
4. Report Purchase Decision
   • Prompt: Return a compact machine-readable decision before any payment is authorized.
