+## Trigger Types
+
+Agent menu triggers use two different invocation types. Knowing which type a trigger uses helps you provide the right input.
+
+### Workflow triggers (no arguments needed)
+
+Most triggers load a structured workflow file. Type the trigger code and the agent starts the workflow, prompting you for input at each step.
+
+Examples: `CP` (Create PRD), `DS` (Dev Story), `CA` (Create Architecture), `QS` (Quick Spec)
+
+### Conversational triggers (arguments required)
+
+Some triggers start a free-form conversation instead of a structured workflow. These expect you to describe what you need alongside the trigger code.
+
+| Agent | Trigger | What to provide |
+| --- | --- | --- |
+| Technical Writer (Paige) | `WD` | Description of the document to write |
+| Technical Writer (Paige) | `US` | Preferences or conventions to add to standards |
+| Technical Writer (Paige) | `MG` | Diagram description and type (sequence, flowchart, etc.) |
+| Technical Writer (Paige) | `VD` | Document to validate and focus areas |
+| Technical Writer (Paige) | `EC` | Concept name to explain |
+
+**Example:**
+
+```text
+WD Write a deployment guide for our Docker setup
+MG Create a sequence diagram showing the auth flow
+EC Explain how the module system works
+```
