Binding Rules

Binding connects a rule to a Context. Once bound, the rule reads its inputs from context facts and writes its outputs back—no API calls required on your end.

How Binding Works

When you bind a rule to a context:

The rule's request schema maps to context facts it reads
The rule's response schema maps to context facts it writes
The rule executes automatically when all its inputs are present (unless set to manual mode)

This is what makes progressive execution work—you submit facts, rules run when ready, results appear as new facts.

Binding a Rule

Open the Rule

Navigate to your rule in the dashboard and open the Settings tab.

Set Input Source

Under Input Source, select From Context and choose the context to bind to.

The rule's request schema fields will map to context facts with matching names. If names don't match exactly, you can configure field mappings.

Set Output Destination

Under Output Destination, select To Context.

The rule's response fields will write to context facts with matching names. These should be marked as output only in the context schema so external systems can't overwrite rule decisions.

Choose Execution Mode

Select when the rule should execute:

Mode	Behavior
Enabled	Runs automatically when all inputs are present
Manual	Only runs when you call `/solve` explicitly
Disabled	Won't run (useful for staged rollouts)

Save

Click Save. The rule is now bound and will participate in progressive execution.

💡

You can bind multiple rules to the same context. They'll execute in dependency order—a rule that reads risk_tier waits for the rule that writes it.

Cascading Rules

When Rule A writes a fact that Rule B needs, B executes automatically after A:

Facts arrive: credit_score, annual_income
       ↓
[Credit Check Rule] executes → writes: risk_tier
       ↓
[Pricing Rule] now has all inputs → executes → writes: rate, max_amount

This happens within a single API response. The cascaded array shows what ran:

{
  "cascaded": [
    { "rule": "credit-check", "result": { "risk_tier": "low" } },
    { "rule": "pricing", "result": { "rate": 4.5, "max_amount": 500000 } }
  ]
}

Viewing Bound Rules

From the Context dashboard, the Rules tab shows all bound rules, their execution mode, and which facts they read/write.
