Add Adaptive Card

Add Adaptive Card

Add an AdaptiveCardPrompt node to an existing Copilot Studio topic. Use this for all Adaptive Card scenarios — display-only cards, input forms, and confirmation flows.

Instructions

1. Auto-discover the agent directory:

`` Glob: agents/**/agent.mcs.yml `` NEVER hardcode an agent name.

1. Clarify requirements from the user if not specified:

• Which topic should the card be added to?
• Which card type (form, info, confirmation)?
• What fields, labels, and placeholders are needed?
• Which topic variables should receive the submitted values?

1. Read the target topic file to understand its structure and find the correct insertion point.

1. Verify the schema if needed:

```bash # Copilot Studio node schema node ${CLAUDESKILLDIR}/../../scripts/schema-lookup.bundle.js summary AdaptiveCardPrompt

# Adaptive Cards element schema (v1.6 — the version supported by Copilot Studio) node ${CLAUDESKILLDIR}/../../scripts/schema-lookup.bundle.js ac-summary TextBlock node ${CLAUDESKILLDIR}/../../scripts/schema-lookup.bundle.js ac-summary Input.Text node ${CLAUDESKILLDIR}/../../scripts/schema-lookup.bundle.js ac-search Action ```

1. Select and adapt the template from [card-templates.md](card-templates.md) matching the requested type.

1. Generate unique IDs for all new nodes (format: _).

1. Insert the node(s) at the correct position in the actions array using Edit.

1. Validate the updated topic file:

``bash node ${CLAUDE_SKILL_DIR}/../../scripts/schema-lookup.bundle.js validate ``

1. Inform the user that they must push (VS Code Extension) and publish (Copilot Studio UI) before testing with /chat-with-agent or /run-tests.

AdaptiveCardPrompt Structure

AdaptiveCardPrompt is the correct node kind for all Adaptive Cards in Copilot Studio. The card JSON is embedded as a multiline YAML literal string under card: |.

- kind: AdaptiveCardPrompt
  id: adaptiveCardPrompt_m9Kp2x
  card: |
    {
      "type": "AdaptiveCard",
      "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
      "version": "1.5",
      "body": [...],
      "actions": [...]
    }
  output:
    binding:
      fieldId: Topic.MyVariable
  outputType:
    properties:
      fieldId:
        type: String

Rules:

• card: | — the literal block scalar is mandatory. Do not use card: > or inline the JSON without it.
• $schema and version are required inside the card JSON.
• The output.binding maps each card input id to a topic variable (Topic.VarName, no = prefix).
• outputType.properties must declare a type for every bound field.
• Use plain binding: — no kind: property inside it.
• Every AdaptiveCardPrompt must have output, outputType, and an Action.Submit button — including display-only info cards. Omitting any of these causes VS Code extension errors (MissingRequiredProperty, AdaptiveCardMissingActionSubmit).
• For info cards with no meaningful inputs, add an Action.Submit (e.g. "OK") and bind a dummy acknowledgement variable (Topic.CardAcknowledged, type String).

Node Comparison

| Node | Use When | |------|----------| | AdaptiveCardPrompt | Any Adaptive Card — with or without input fields | | SendActivity | Plain text messages with optional {} variable interpolation |

Do NOT use SendActivity with an attachments array for Adaptive Cards.

Field Validation

Do NOT use style: "Email" or style: "Tel" for validation — these only change the mobile keyboard and do not validate on submit. Always use regex:

{
  "type": "Input.Text",
  "id": "email",
  "label": "Email address",
  "placeholder": "Enter your email address",
  "isRequired": true,
  "regex": "^[a-zA-Z0-9._%+\\-]+@[a-zA-Z0-9.\\-]+\\.[a-zA-Z]{2,}$",
  "errorMessage": "Enter a valid email address"
}

{
  "type": "Input.Text",
  "id": "mobile",
  "label": "Mobile number",
  "placeholder": "Enter your mobile number",
  "isRequired": true,
  "regex": "^[+]?[0-9][\\s\\-\\(\\)0-9]{6,14}$",
  "errorMessage": "Enter a valid mobile number"
}

| Approach | Validates on submit? | Notes | |----------|---------------------|-------| | regex | Yes — blocks submit if pattern fails | Use for email, phone, any format | | isRequired: true | Yes — blocks submit if empty | Mandatory fields | | style: "Email" | No | Keyboard hint only — never use for validation | | style: "Tel" | No | Keyboard hint only — never use for validation |

> Rule: Every Input.ChoiceSet (and any required input) must have a label property, or the VS Code extension raises AdaptiveCardInputIsRequiredMissingLabel.

Output Binding

• Card input id values must exactly match the keys in output.binding.
• Topic variable references: Topic.VariableName (no = prefix).
• Declare every bound field in outputType.properties with its type.

output:
  binding:
    userName: Topic.UserName
    userEmail: Topic.UserEmail
    category: Topic.Category
outputType:
  properties:
    userName:
      type: String
    userEmail:
      type: String
    category:
      type: String

Dynamic Text Around Cards

Card JSON is static — Power Fx expressions and {} interpolation do not work inside the card body. Use SendActivity before or after AdaptiveCardPrompt for dynamic content:

- kind: SendActivity
  id: sendMessage_Rz4Wq1
  activity: "Hello {Topic.UserName}, please complete the form below."

- kind: AdaptiveCardPrompt
  id: adaptiveCardPrompt_m9Kp2x
  card: |
    { ... }

Card Types Quick Reference

| Type | Has inputs? | Has output? | Template | |------|------------|--------------|---------| | form | Yes | Yes | Form Card | | info | No (dummy acknowledgement) | Yes (always required) | Info Card | | confirmation | Yes (ChoiceSet) | Yes | Confirmation Card |

For full YAML examples of each type, see [card-templates.md](card-templates.md).
