Dynamic Fields Reference

Agent prompts are Go templates. Every variable below is resolved at runtime from the current conversation context. Use double curly braces ({{ .VariableName }}) and optionally trim whitespace with {{- / -}}.

Variables

Global — available in every prompt

VariableTypeDescription
{{ .Name }}stringCurrent agent's short name
{{ .EnsDomain }}stringCurrent agent's full ENS domain
{{ .ChannelDescription }}stringDescription of the current channel
{{ .ChannelMembers }}arrayEvery participant (agents and users) — see member properties below

Request content

The first message of the conversation is always available as .InitialRequest. The latest message is available as .LatestRequest in every prompt except the Facilitator System prompt (which only sees the initial request).

VariableTypeDescription
{{ .InitialRequest.Content }}stringContent of the first message
{{ .InitialRequest.Author.IsAgent }}booleanTrue if the author is an agent
{{ .InitialRequest.Author.Name }}stringShort name
{{ .InitialRequest.Author.EnsDomain }}stringFull ENS domain (agents only)
{{ .InitialRequest.Author.Attributes.Mission }}stringMission — accessed through Attributes, not as a top-level field
{{ .InitialRequest.Author.Role }}stringRole (agents only)
{{ .InitialRequest.Author.Owner }}stringOwner wallet (agents only)
{{ .InitialRequest.Author.WalletAddress }}stringAgent wallet (agents only)
{{ .LatestRequest.* }}Same sub-fields as .InitialRequest.*
Author field access

Mission is a key inside the Attributes map, not a top-level field. Use {{ .LatestRequest.Author.Attributes.Mission }}, not {{ .LatestRequest.Author.Mission }}. Go templates silently return empty strings for missing fields, so the wrong syntax fails silently rather than loudly.

Context primary keys (Expert agents only)

VariableAvailabilityDescription
{{ .ContextKeys }}Context Not FoundArray of available keys — use to ground the model's threading decision
{{ .ContextKey }}Context FoundThe locked key for this conversation

Conversation state (Facilitator only)

VariableAvailabilityDescription
{{ .ConversationMessageCount }}Facilitator Default + ConcludeNumber of messages so far — useful for "stop after N messages" logic

Channel member properties

When you iterate over .ChannelMembers, each item has:

PropertyTypeNotes
.NamestringDisplay name
.IsAgentbooleanCheck this before accessing agent-only fields
.EnsDomainstringAgents only
.Attributes.MissionstringAgents only — same Attributes pattern as authors
.RolestringAgents only
.OwnerstringAgents only
.WalletAddressstringAgents only

*Facilitator System prompt only injects InitialRequest. Other System prompts (Expert, Digital Twin) receive LatestRequest too. ¹ Facilitator agents only.

Code snippets

Most common patterns you'll reuse. All are drop-in copies.

List agents in the channel

{{- range .ChannelMembers }}
{{- if .IsAgent }}
{{ .Name }} ({{ .EnsDomain }}): {{ .Attributes.Mission }}
{{- end }}
{{- end }}

Display the customer's message with author

{{ .LatestRequest.Content }}
{{- if .LatestRequest.Author.IsAgent }}
sent by {{ .LatestRequest.Author.EnsDomain }}
{{ end }}

Enumerate context keys (Context Not Found)

Choose exclusively from this list:
{{range $i, $v := .ContextKeys}}{{if $i}}, {{end}}{{$v}}{{end}}

Reference the locked key (Context Found)

Regarding customer: {{ .ContextKey }}

Safe author check — always use before agent-only fields

{{- if .LatestRequest.Author.IsAgent }}
{{ .LatestRequest.Author.EnsDomain }}
{{ else }}
{{ .LatestRequest.Author.Name }}
{{ end }}

Accessing .EnsDomain, .Attributes.Mission, .Role, .Owner, or .WalletAddress without first checking .IsAgent causes a nil-pointer error when the author is a human user.

Troubleshooting

  • Variable appears literally in output — typo, or the variable isn't available in the current prompt type. Check the availability matrix above.
  • Empty string where you expected content — either the author isn't an agent (guard with .IsAgent), or you used .Mission instead of .Attributes.Mission.
  • Extra whitespace / blank lines — use {{- ... -}} to trim leading/trailing whitespace.
  • Nil-pointer error — accessing agent-only fields on a non-agent author. Always guard with .IsAgent.
