machine-purchase-roi-gate

Try it

Make a rational buy/defer/reject decision for one machine service call before any payment.

What it does

Evaluates whether a single machine-service purchase makes financial sense. The workflow collects explicit assumptions (price, fee, failure probability, retry cost, output value, budget), validates the JSON schema, runs a deterministic calculation, and returns a structured decision. It outputs expected net value, financial ROI percentage, capital at risk, and the maximum rational price the agent should pay. The skill never accesses wallets, signs transactions, or broadcasts payments. Designed for bounded, single-call purchase decisions within an AgentPMT workflow.

When to use it

  • Agent evaluates whether to proceed with one machine service purchase
  • Validate economic assumptions before committing to payment
  • Calculate maximum rational price for a service call
  • Get a machine-readable buy/defer/reject decision with binding reasoning

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.

Questions people ask

What inputs does this skill require?
The skill requires: service price, fee, failure probability (0-1), retry cost, output value, and budget. All assumptions must be explicitly provided by the caller; the skill does not introduce its own market prices or probabilities.
What decision does it return?
It returns one of three outcomes: buy, defer, or reject, along with the binding reason. It also outputs expected_net_value_usdc, financial_roi_percent, total_outlay_usdc, capital_at_risk_usdc, and max_rational_service_price_usdc.
Does this skill execute any payment?
No. The skill explicitly never accesses a wallet, signs, pays, or broadcasts. It only produces a structured decision based on validated inputs.
