Copilot Studio YAML Reference

Core File Types

File	Purpose
`agent.mcs.yml`	Main agent metadata (kind: GptComponentMetadata)
`settings.mcs.yml`	Agent settings and configuration
`connectionreferences.mcs.yml`	Connector references
`topics/*.mcs.yml`	Conversation topics (kind: AdaptiveDialog)
`actions/*.mcs.yml`	Connector-based actions (kind: TaskDialog)
`knowledge/*.mcs.yml`	Knowledge sources (kind: KnowledgeSourceConfiguration)
`variables/*.mcs.yml`	Global variables (kind: GlobalVariableComponent)
`agents/*.mcs.yml`	Child agents (kind: AgentDialog)

Trigger Types

Topics with OnRecognizedIntent have two routing mechanisms — which one matters depends on the orchestration mode:

modelDescription — used by generative orchestration (GenerativeActionsEnabled: true). The AI orchestrator reads this to decide routing. Primary mechanism for generative agents.
Trigger phrases (triggerQueries) — used by classic orchestration. Pattern-matched against the user's utterance. Secondary hints when generative orchestration is enabled.

System triggers (OnConversationStart, OnUnknownIntent, OnError, etc.) fire automatically and don't use either mechanism.

Kind	Purpose
`OnRecognizedIntent`	Trigger phrases matched
`OnConversationStart`	Conversation begins
`OnUnknownIntent`	No topic matched (fallback)
`OnEscalate`	User requests human agent
`OnError`	Error handling
`OnSystemRedirect`	Triggered by redirect only
`OnSelectIntent`	Multiple topics matched (disambiguation)
`OnSignIn`	Authentication required
`OnToolSelected`	Child agent invocation
`OnKnowledgeRequested`	Custom knowledge source search triggered (YAML-only, no UI)
`OnGeneratedResponse`	Intercept AI-generated response before sending
`OnOutgoingMessage`	Non-functional (2026-03-15) — exists in schema but does not fire at runtime. Do not use.

YAML-Only Features

These features work at runtime but are not visible in the Copilot Studio UI. Warn users that UI edits may silently remove them.

Feature	Notes
`triggerCondition` on knowledge sources	The UI only exposes this as an on/off toggle (`=false` to exclude from `UniversalSearchTool`). Arbitrary Power Fx expressions (e.g., `=Global.UserDepartment = "HR"`) work at runtime but can only be set via YAML. Use with caution. (2026-03-16)

Action Types

Kind	Purpose
`SendActivity`	Send a message
`Question`	Ask user for input
`SetVariable`	Set/compute a variable (Power Fx expression, prefix `=`)
`SetTextVariable`	Set a text variable using template interpolation (`{}`). Useful for converting non-text types (e.g., Number) to text: `"You have {Topic.Count} items"`
`ConditionGroup`	Branching logic
`BeginDialog`	Call another topic
`ReplaceDialog`	Replace current topic
`EndDialog`	End current topic
`CancelAllDialogs`	Cancel all topics
`ClearAllVariables`	Clear variables
`SearchAndSummarizeContent`	Generative answers (grounded in knowledge)
`AnswerQuestionWithAI`	AI answer (conversation history + general knowledge only)
`EditTable`	Modify a collection
`CSATQuestion`	Customer satisfaction
`LogCustomTelemetryEvent`	Logging
`OAuthInput`	Sign-in prompt
`SearchKnowledgeSources`	Search knowledge sources (returns raw results, no AI summary)
`CreateSearchQuery`	AI-generated search query from user input

Connector Actions (TaskDialog)

Connector actions (kind: TaskDialog) invoke external connector operations. They are stored in actions/ and require a connection reference in connectionreferences.mcs.yml.

Use /add-action to create new actions from available connectors. The schema describes the structural properties of TaskDialog and InvokeConnectorTaskAction, but the specific inputs and outputs for each connector operation are connector-specific — use the connector lookup script (connector-lookup.bundle.js) to get the full operation details.

Action Structure

Field	Purpose
`kind: TaskDialog`	Identifies this as a connector action
`inputs`	Inputs: `AutomaticTaskInput` (AI-provided) or `ManualTaskInput` (fixed value)
`modelDisplayName`	Display name for AI orchestrator routing
`modelDescription`	Description for AI orchestrator routing
`outputs`	Output property names returned by the connector
`action.kind`	Always `InvokeConnectorTaskAction` for connector actions
`action.connectionReference`	Logical name of the connection (registered in `connectionreferences.mcs.yml`)
`action.connectionProperties.mode`	`Maker` (maker's credentials) or `Invoker` (end user's credentials)
`action.operationId`	The connector's specific operation identifier
`outputMode`	Usually `All` — exports all operation outputs

Input Types

Input Kind	Use When	Notes
`AutomaticTaskInput`	The AI orchestrator should provide the value based on context	Includes `description` for the AI to understand what to provide
`ManualTaskInput`	A fixed/hardcoded value (e.g., timezone, folder path)	Can only hardcode strings. Non-string values (IDs, enums) should be reviewed by the user after pushing

`$`-Prefixed Property Names (SharePoint, OData)

Some connectors (notably SharePoint) use OData parameters like $filter, $orderby, $top. These require special quoting in TaskDialog YAML — both single and double quotes:

# TaskDialog (actions/*.mcs.yml) — CORRECT
- kind: ManualTaskInput
  propertyName: "'$filter'"
  value: "Status eq 'Active'"

"'$filter'" means: the outer "" are YAML string delimiters; the inner '' are part of the literal value sent to the runtime. Using $filter, "$filter", or '$filter' alone will fail.

InvokeConnectorAction (inline in topics) uses a different format — the parameters/ prefix with no inner single quotes:

# InvokeConnectorAction (inside topics) — CORRECT
- kind: InvokeConnectorAction
  operationId: GetItems
  input:
    parameters/$filter: "Status eq 'Active'"

Never mix these two formats.

System Variables

Variable	Description
`System.Bot.Name`	Agent's name
`System.Activity.Text`	User's current message
`System.Conversation.Id`	Conversation identifier
`System.Conversation.InTestMode`	True if in test chat
`System.FallbackCount`	Number of consecutive fallbacks
`System.Error.Message`	Error message
`System.Error.Code`	Error code
`System.SignInReason`	Why sign-in was triggered
`System.Recognizer.IntentOptions`	Matched intents for disambiguation
`System.Recognizer.SelectedIntent`	User's selected intent
`System.SearchQuery`	AI-rewritten search query (available in `OnKnowledgeRequested`)
`System.KeywordSearchQuery`	Keyword version of search query (available in `OnKnowledgeRequested`)
`System.SearchResults`	Table to populate with custom search results — schema: Content, ContentLocation, Title (available in `OnKnowledgeRequested`)
`System.ContinueResponse`	Set to `false` in `OnGeneratedResponse` to suppress auto-send
`System.Response.FormattedText`	The AI-generated response text (available in `OnGeneratedResponse`)

Variable Scopes

Prefix	Scope	Lifetime
`Topic.<name>`	Topic variable	Current topic only
`Global.<name>`	Global variable	Entire conversation (defined in `variables/` folder)
`System.<name>`	System variable	Built-in, read-only

Global variables are defined as YAML files in variables/<Name>.mcs.yml (kind: GlobalVariableComponent). aIVisibility accepts UseInAIContext (orchestrator can read and reason about the value) or Hidden (orchestrator unaware — use for flags and internal bookkeeping).

Prebuilt Entities

Entity	Use Case
`BooleanPrebuiltEntity`	Yes/No questions
`NumberPrebuiltEntity`	Numeric inputs
`StringPrebuiltEntity`	Free text
`DateTimePrebuiltEntity`	Date/time
`EMailPrebuiltEntity`	Email addresses

Power Fx Expression Reference

Only use functions from the supported list below. Copilot Studio supports a subset of Power Fx — using unsupported functions will cause errors.

# Arithmetic
value: =Text(Topic.number1 + Topic.number2)

# Date formatting
value: =Text(Now(), DateTimeFormat.UTC)

# Conditions
condition: =System.FallbackCount < 3
condition: =Topic.EndConversation = true
condition: =!IsBlank(Topic.Answer)
condition: =System.Conversation.InTestMode = true
condition: =System.SignInReason = SignInReason.SignInRequired
condition: =System.Recognizer.SelectedIntent.TopicId = "NoTopic"

# String interpolation in activity (uses {} without =)
activity: "Error: {System.Error.Message}"
activity: "Error code: {System.Error.Code}, Time (UTC): {Topic.CurrentTime}"

# Record creation
value: "={ DisplayName: Topic.NoneOfTheseDisplayName, TopicId: \"NoTopic\", TriggerId: \"NoTrigger\", Score: 1.0 }"

# Variable initialization (first assignment uses init: prefix)
variable: init:Topic.UserEmail
