FLOW (structured execution steps)

The FLOW: section adds structured execution steps to any agent. It defines a step-by-step execution graph where each step declares actions (collect information, call tools, respond, branch) and transitions to other steps. Agents operate in reasoning mode by default, where the LLM autonomously decides actions based on the goal. Adding a FLOW: section gives an agent a structured step graph, with each step declaring whether it uses LLM reasoning or deterministic execution via the REASONING: toggle.

Flow structure

Basic syntax

FLOW:
  entry_point: start

  steps:
    - start
    - collect_info
    - process
    - complete

  start:
    REASONING: false
    SET:
      status = "pending"
    RESPOND: "Welcome! Let me help you get started."
    THEN: collect_info

  collect_info:
    REASONING: false
    GATHER:
      - name: required
        prompt: "What is your name?"
    THEN: process

  process:
    REASONING: false
    CALL: process_request
      WITH:
        name: name
      AS: result
    RESPOND: "Done! Your request has been processed."
    THEN: complete

  complete:
    REASONING: false
    RESPOND: "Thank you for using our service. Goodbye!"

Entry point

The entry_point: property declares which step the flow begins at:

FLOW:
  entry_point: greeting

Property	Type	Required	Default	Description
`entry_point`	`string`	No	First step in the `steps` list	The step name where execution begins

If omitted, execution starts at the first step listed in the steps array.

Step list

The steps: array declares the ordered list of step names. While steps can transition to any other step (not just the next in order), the list establishes the canonical ordering:

FLOW:
  steps:
    - greeting
    - collect_account
    - verify
    - process
    - complete

Step definitions

Each step is defined as a named block under FLOW: with its properties indented:

FLOW:
  greeting:
    REASONING: false
    RESPOND: "Hello! How can I help you today?"
    THEN: collect_account

Per-step REASONING toggle

Every step in a FLOW: section must declare REASONING: true or REASONING: false. This controls whether the step uses LLM reasoning or deterministic execution.

FLOW:
  analyze_request:
    REASONING: true
    GOAL: "Analyze the customer's request and determine the best course of action"
    AVAILABLE_TOOLS: [search_knowledge, classify_intent]
    EXIT_WHEN: intent_classified == true
    MAX_TURNS: 5
    THEN: route_request

  route_request:
    REASONING: false
    CHECK: intent == "billing"
    ON_FAIL: general_support
    THEN: billing_flow

Property	Type	Required	Default	Description
`REASONING`	`boolean`	Yes	—	`true` for LLM-driven reasoning, `false` for deterministic execution

Reasoning step properties

When REASONING: true, the following additional properties are available:

Property	Type	Required	Default	Description
`GOAL`	`string`	No	Agent-level `GOAL:`	Step-specific goal (overrides the agent’s goal for this step)
`AVAILABLE_TOOLS`	`string[]`	No	All agent tools	Subset of agent tools available in this step
`EXIT_WHEN`	`string`	No	none	Condition that ends the reasoning loop
`MAX_TURNS`	`number`	No	`10`	Maximum reasoning turns before forced exit
`STEP_CONSTRAINTS`	`string[]`	No	none	Constraints specific to this reasoning zone

Validation rules:

A step with REASONING: true must have either a step-level GOAL or an agent-level GOAL: defined.

A step with REASONING: false should not have a GOAL (it has no effect on deterministic steps).

A step with REASONING: false should not have AVAILABLE_TOOLS (use CALL to invoke tools deterministically).

Entry guards

The WHEN: property on a step defines a condition that must be true for the step to execute. If the condition is false, the step is skipped:

FLOW:
  international_details:
    REASONING: false
    WHEN: "transfer_type == 'international'"
    GATHER:
      - swift_code: required
        prompt: "What is the SWIFT/BIC code?"
    THEN: validate_details

Property	Type	Required	Default	Description
`WHEN`	`string`	No	none	Condition expression that must be true for the step to execute

Attempt limiting

Steps can limit the number of times they execute (useful for retry loops):

FLOW:
  collect_pin:
    REASONING: false
    MAX_ATTEMPTS: 3
    ON_EXHAUSTED: lockout
    GATHER:
      - pin: required
        prompt: "Enter your PIN."
    THEN: verify_pin

Property	Type	Required	Default	Description
`MAX_ATTEMPTS`	`number`	No	none	Maximum number of times this step can execute
`ON_EXHAUSTED`	`string`	No	none	Step to transition to after max attempts exhausted

Step actions

SAY / RESPOND

The RESPOND: action sends a message to the user. It supports template interpolation with {{variable}} syntax:

FLOW:
  greeting:
    REASONING: false
    RESPOND: "Hello, {{customer_name}}! Your balance is {{balance}}."
    THEN: next_step

Multi-line responses use pipe block syntax:

FLOW:
  summary:
    REASONING: false
    RESPOND: |
      Here is your transfer summary:
      From: {{source_account}}
      To: {{beneficiary_name}}
      Amount: {{amount}} {{currency}}
    THEN: confirm

PRESENT

The PRESENT: action displays a formatted presentation before collection. It is used alongside GATHER: to show the user what has been collected so far:

FLOW:
  review:
    REASONING: false
    PRESENT: |
      Beneficiary: {{beneficiary_name}}
      Account: {{MASK(beneficiary_account, "last4")}}
      Bank: {{beneficiary_bank_name}}
    GATHER:
      - confirmation: required
    THEN: process

GATHER in flow steps

Within a flow step, GATHER: uses a list syntax different from the top-level GATHER: section:

FLOW:
  collect_details:
    REASONING: false
    GATHER:
      - source_account: required
        prompt: "Your account number?"
    THEN: next_step

Multi-field collection

Collect multiple fields in a single step using the FIELDS: sub-block:

FLOW:
  collect_beneficiary:
    REASONING: false
    GATHER:
      FIELDS:
        - beneficiary_name: required
          prompt: "Full legal name on the account."
        - beneficiary_account: required
          prompt: "Account number or IBAN."
        - beneficiary_bank: required
          prompt: "Name of the bank."
        - country: required
          prompt: "Country of the bank."
          default: "US"
          infer: true
      STRATEGY: llm
    CORRECTIONS: true
    COMPLETE_WHEN: beneficiary_name AND beneficiary_account AND beneficiary_bank AND country
    THEN: validate

Flow gather field properties

Each field in a flow GATHER: supports these properties:

Property	Type	Required	Default	Description
`required` / optional value after name	`boolean`	No	`true`	Whether the field must be collected
`prompt`	`string`	No	none	Question shown to the user
`type`	`string`	No	`"string"`	Data type
`default`	`any`	No	none	Default value
`validation`	`string`	No	none	Validation expression
`infer`	`boolean`	No	`false`	Allow LLM inference
`infer_confidence`	`number`	No	`0.8`	Minimum inference confidence
`infer_confirm`	`boolean`	No	`true`	Confirm inferred values
`extraction_hints`	`string[]`	No	none	LLM extraction guidance
`range`	`boolean`	No	`false`	Collect as range
`list`	`boolean`	No	`false`	Collect as array
`activation`	`string` \| `{when: string}`	No	none	Activation mode
`depends_on`	`string[]`	No	none	Field dependencies
`prompt_mode`	`"ask"` \| `"extract_only"`	No	`"ask"`	Prompt usage mode

Strategy

The STRATEGY: property on a flow GATHER: block controls the collection approach:

Value	Description
`llm`	Use LLM to extract values from natural conversation
`pattern`	Use pattern matching and extraction rules
`hybrid`	Combine LLM and pattern matching

CORRECTIONS

When CORRECTIONS: true, the user can naturally correct previously collected values without restarting the step:

FLOW:
  collect_info:
    REASONING: false
    GATHER:
      - name: required
      - email: required
    CORRECTIONS: true
    THEN: next_step

COMPLETE_WHEN

The COMPLETE_WHEN: condition specifies when the gather step is considered complete:

FLOW:
  collect_all:
    REASONING: false
    GATHER:
      FIELDS:
        - field_a: required
        - field_b: required
        - field_c: optional
    COMPLETE_WHEN: field_a AND field_b
    THEN: process

CALL…WITH…AS

The CALL: action invokes a tool. Use WITH: to pass parameters and AS: to bind the result to a variable:

FLOW:
  verify_step:
    REASONING: false
    CALL: verify_account
      WITH:
        account_id: source_account
      AS: acctResult
    RESPOND: "Account verified: {{acctResult.owner_name}}"
    THEN: next_step

Property	Type	Required	Default	Description
`CALL`	`string`	—	—	Tool name to invoke
`WITH`	`Record<string, string>`	No	none	Key-value parameter mapping
`AS`	`string`	No	none	Variable name to bind the tool result

WITH parameters

The WITH: block maps tool parameter names to values or variable references:

CALL: calculate_fees
  WITH:
    transfer_type: transfer_type
    amount: amount
    currency: currency
    destination_country: beneficiary_country
  AS: feeResult

Values can be:

Variable references: amount (resolves the session variable amount)
Literal strings: "domestic"
Expressions: COALESCE(reference, "")

SET

The SET: action assigns values to session variables:

FLOW:
  init:
    REASONING: false
    SET:
      status = "pending"
      retry_count = 0
      sanctions_clear = false
    THEN: next_step

Each assignment uses variable = expression syntax. The expression is resolved at execution time and can reference:

Literal values: "pending", 0, true, false
Variable references: acctResult.balance
Function calls: FORMAT_CURRENCY(amount, "USD"), COALESCE(value, "default"), ADD(a, b), SUB(a, b), ROUND(n, decimals)
Unique ID generation: UNIQUE_ID(12)
Current timestamp: NOW()

CHECK

The CHECK: action evaluates a condition. If the condition is false, execution transitions to the ON_FAIL: step:

FLOW:
  check_limits:
    REASONING: false
    CHECK: amount <= available_balance AND ADD(daily_used, amount) <= daily_limit
    ON_FAIL: over_limit
    THEN: proceed

Property	Type	Required	Default	Description
`CHECK`	`string`	—	—	Condition expression to evaluate
`ON_FAIL`	`string`	No	none	Step to go to if the condition is false

CLEAR

The CLEAR: action removes variables from the session context:

FLOW:
  reset_beneficiary:
    REASONING: false
    CLEAR: [beneficiary_name, beneficiary_account, beneficiary_id]
    THEN: collect_beneficiary

TRANSFORM

The TRANSFORM: action filters, maps, sorts, and limits an array from the session context:

FLOW:
  filter_results:
    REASONING: false
    TRANSFORM:
      SOURCE: search_results
      AS: hotel
      INTO: filtered_hotels
      FILTER: "hotel.rating >= 4"
      MAP:
        name: hotel.name
        price: hotel.price_per_night
        rating: hotel.rating
      SORT_BY: price asc
      LIMIT: 5
    THEN: show_results

Property	Type	Required	Default	Description
`SOURCE`	`string`	Yes	—	Dot-path to the source array
`AS`	`string`	Yes	—	Loop variable name
`INTO`	`string`	Yes	—	Output variable name
`FILTER`	`string`	No	none	Condition expression using the loop variable
`MAP`	`Record<string, string>`	No	none	Field mapping expressions
`SORT_BY`	`string`	No	none	Sort field and direction (`asc` or `desc`)
`LIMIT`	`number`	No	none	Maximum number of items in the output

Branching and control flow

THEN / ON_FAIL

The most basic branching: THEN: specifies the next step on success, and ON_FAIL: specifies the step on failure:

FLOW:
  check_status:
    REASONING: false
    CHECK: account_status == "active"
    ON_FAIL: inactive_account
    THEN: proceed

ON_RESULT

ON_RESULT: provides multi-way branching based on the result of a CALL: action. Each branch has an IF: condition, optional actions, and a THEN: transition:

FLOW:
  verify_step:
    REASONING: false
    CALL: verify_account
      WITH:
        account_id: source_account
      AS: acctResult
    ON_RESULT:
      - IF: acctResult.status == "active"
        SET:
          customer_name = acctResult.owner_name
          balance = acctResult.available_balance
        RESPOND: "Account verified. Hello, {{customer_name}}."
        THEN: next_step
      - IF: acctResult.status == "frozen"
        RESPOND: "Your account is frozen. Please contact your branch."
        THEN: end
      - ELSE:
        RESPOND: "Account not found. Please check the number."
        THEN: collect_account

ON_RESULT branch properties

Property	Type	Required	Default	Description
`IF`	`string`	No	—	Condition expression. Omit for `ELSE` branch.
`RESPOND`	`string`	No	none	Message to display
`SET`	`Record<string, string>`	No	none	Variable assignments
`CALL`	`string`	No	none	Optional nested tool call
`THEN`	`string`	Yes	—	Next step

The ELSE branch (a branch with no IF condition) matches when no other condition is true.

ON_SUCCESS / ON_FAIL

An alternative to ON_RESULT: for simpler success/failure branching:

FLOW:
  call_api:
    REASONING: false
    CALL: submit_request
      WITH:
        data: request_data
      AS: result
    ON_SUCCESS:
      RESPOND: "Request submitted: {{result.id}}"
      THEN: done
    ON_FAIL:
      RESPOND: "Request failed. Please try again."
      THEN: retry_step

Both ON_SUCCESS: and ON_FAIL: support conditional branches:

FLOW:
  process:
    REASONING: false
    CALL: process_order
      AS: orderResult
    ON_SUCCESS:
      - IF: orderResult.express == true
        RESPOND: "Express order confirmed!"
        THEN: express_fulfillment
      - ELSE:
        RESPOND: "Order confirmed."
        THEN: standard_fulfillment
    ON_FAIL:
      - IF: orderResult.error == "out_of_stock"
        RESPOND: "Item is out of stock."
        THEN: suggest_alternatives
      - ELSE:
        RESPOND: "An error occurred."
        THEN: error_handling

ON_INPUT

ON_INPUT: provides branching based on user input, typically used after a GATHER: action:

FLOW:
  confirm:
    REASONING: false
    GATHER:
      - confirmation: required
    ON_INPUT:
      - IF: input.contains("yes") OR input.contains("confirm")
        THEN: execute
      - IF: input.contains("no") OR input.contains("cancel")
        RESPOND: "Cancelled."
        THEN: cleanup
      - ELSE:
        RESPOND: "Please type 'yes' to confirm or 'no' to cancel."
        THEN: confirm

Digressions

Digressions are intent-based escapes that can interrupt the current step. They match user intent patterns and respond accordingly:

FLOW:
  collect_details:
    REASONING: false
    GATHER:
      - account: required

    DIGRESSIONS:
      - INTENT: "what is swift"
        RESPOND: "A SWIFT code is an 8 or 11 character code identifying a bank internationally."
        RESUME: true
      - INTENT: "cancel"
        RESPOND: "Transaction cancelled."
        GOTO: cleanup
      - INTENT: "speak to agent"
        RESPOND: "Connecting you with a specialist."
        DELEGATE: Live_Agent

Digression properties

Property	Type	Required	Default	Description
`INTENT`	`string`	Yes	—	Intent pattern to match
`KEYWORDS`	`string[]`	No	none	Explicit keywords for matching
`CONDITION`	`string`	No	none	Additional condition to check
`RESPOND`	`string`	No	none	Response message
`RESUME`	`boolean`	No	`false`	Return to the current step after handling
`GOTO`	`string`	No	none	Transition to a specific step
`DELEGATE`	`string`	No	none	Delegate to another agent
`CALL`	`string`	No	none	Tool to invoke
`CLEAR`	`string[]`	No	none	Variables to clear

When RESUME: true, the user returns to the interrupted step after the digression response. When GOTO: is specified, the flow transitions to that step instead.

Global digressions

Digressions declared at the flow level (under global_digressions:) are available at every step:

FLOW:
  global_digressions:
    - INTENT: "cancel"
      RESPOND: "Transaction cancelled."
      GOTO: cleanup

    - INTENT: "help"
      RESPOND: "I can help with account inquiries, transfers, and balance checks."
      RESUME: true

    - INTENT: "speak to agent"
      RESPOND: "Connecting you with a live agent."
      DELEGATE: Live_Agent_Transfer

Sub-intents

Sub-intents are scoped intents valid only within a specific step. They handle step-specific user requests like corrections or clarifications:

FLOW:
  collect_beneficiary:
    REASONING: false
    GATHER:
      FIELDS:
        - name: required
        - account: required
        - bank: required

    SUB_INTENTS:
      - INTENT: "change name"
        CLEAR: [name]
        RESPOND: "What is the correct name?"
      - INTENT: "change account"
        CLEAR: [account]
        RESPOND: "What is the correct account number?"
      - INTENT: "change bank"
        CLEAR: [bank, routing_code]
        RESPOND: "What is the correct bank name?"

Sub-intent properties

Property	Type	Required	Default	Description
`INTENT`	`string`	Yes	—	Intent pattern to match
`RESPOND`	`string`	No	none	Response message
`CLEAR`	`string[]`	No	none	Variables to clear (triggers re-collection)
`SET`	`Record<string, string>`	No	none	Variables to set
`CALL`	`string`	No	none	Tool to invoke
`RESUME`	`boolean`	No	`true`	Stay in the current step

Interactive actions

Flow steps can present interactive UI elements (buttons, selects, inputs) to the user. These are attached to RESPOND: messages and handled with ON_ACTION: callbacks.

Action elements

Interactive actions are defined in an ACTIONS: block within a step:

FLOW:
  choose_option:
    REASONING: false
    RESPOND: "How would you like to proceed?"
    ACTIONS:
      - id: "option_transfer"
        type: button
        label: "Wire Transfer"
        value: "wire"
      - id: "option_ach"
        type: button
        label: "ACH Transfer"
        value: "ach"
      - id: "option_check"
        type: button
        label: "Send a Check"
        value: "check"
    ON_ACTION:
      - ACTION: "option_transfer"
        SET:
          transfer_method = "wire"
        THEN: wire_flow
      - ACTION: "option_ach"
        SET:
          transfer_method = "ach"
        THEN: ach_flow

  - id: "name_input"
    type: input
    label: "Your name"
    inputType: text
    required: true

    type: input
    label: "Your email"
    inputType: email
    required: true
  SUBMIT_LABEL: "Submit"
  SUBMIT_ID: "form_submit"

ON_ACTION callbacks

The ON_ACTION: block defines handlers for user interactions with action elements:

ON_ACTION:
  - ACTION: "confirm_btn"
    RESPOND: "Confirmed! Processing your request."
    SET:
      confirmed = true
    THEN: process_step

    RESPOND: "Here is your transfer summary."
    RICH_CONTENT:
      MARKDOWN: |
        ## Wire Transfer Summary

FLOW:
  call_external:
    REASONING: false
    CALL: external_api
      WITH:
        query: user_query
      AS: apiResult
    ON_ERROR:
      tool_timeout:
        RESPOND: "The service is responding slowly. Retrying..."
        RETRY: 2
        THEN: CONTINUE
      tool_error:
        RESPOND: "An error occurred. Let me try a different approach."
        THEN: fallback_step
