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
- Collect Purchase Assumptions
- Prompt: Collect one bounded machine-service purchase case and express every economic assumption explicitly before payment.
- 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.
- 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.
- Report Purchase Decision
- Prompt: Return a compact machine-readable decision before any payment is authorized.
