PowerPlatform - Flow Generation Skill

Generate Power Automate flows from natural language descriptions using connector schemas exported from your work environment.

Examples

Example: Simple notification flow

Example: Approval workflow

User: "Make a flow for document approval - when a file is added to SharePoint, start an approval, then move to approved/rejected folder"
-> Uses SharePoint trigger + Approvals + SharePoint actions
-> Includes conditional branching
-> Outputs deployable solution

Architecture

Work Repo (schemas)                    PAI (this skill)
~/Projects/work/scripts/               ~/.claude/skills/PowerPlatform/

└── generated/           <──writes──   [Solution ZIPs]

Workflow

1. Check Available Connectors

Before generating, read the manifest to see what connectors are available:

cat ~/Projects/work/scripts/power-platform/manifest.json

If manifest.json doesn't exist or is stale, inform user to run the export script at work.

2. Parse User Request

Extract from natural language:

• Trigger: What starts the flow (email arrives, file created, scheduled, manual)
• Actions: What the flow does (send message, create item, update record)
• Conditions: Any branching logic (if/then, switch)
• Data flow: What data passes between steps

3. Generate Flow Definition

Create the flow JSON following Power Automate schema. Key structure:

{
  "properties": {
    "definition": {
      "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
      "triggers": { ... },
      "actions": { ... }
    },
    "connectionReferences": { ... }
  }
}

4. Package as Solution

Wrap in solution structure for import:

solution/
├── [Content_Types].xml
├── customizations.xml
├── solution.xml
└── Workflows/
    └── {flow-guid}-{flow-name}.json

5. Output

Save to: ~/Projects/work/scripts/power-platform/generated/

Connection References

Flows use connection references that map to actual connections in the target environment. Use placeholder IDs that will be resolved on import:

"connectionReferences": {
  "shared_teams": {
    "connectionName": "shared_teams",
    "source": "Embedded",
    "id": "/providers/Microsoft.PowerApps/apis/shared_teams",
    "tier": "NotSpecified"
  }
}

On import, Power Platform prompts user to map these to their actual connections.

Expression Syntax

Power Automate uses a specific expression language. Common patterns:

Dynamic Content References

@{triggerOutputs()?['body/subject']}           # Email subject from trigger
@{body('Get_item')?['Title']}                  # Field from previous action
@{items('Apply_to_each')?['name']}             # Current item in loop

Functions

@{utcNow()}                                    # Current timestamp
@{concat('Hello ', triggerBody()?['name'])}   # String concatenation
@{if(equals(1,1),'yes','no')}                 # Conditional
@{length(body('Get_items')?['value'])}        # Array length
@{formatDateTime(utcNow(),'yyyy-MM-dd')}      # Date formatting

Conditions

"expression": {
  "and": [
    { "contains": ["@triggerOutputs()?['body/subject']", "urgent"] },
    { "equals": ["@triggerOutputs()?['body/importance']", "high"] }
  ]
}

See reference/expressions.md for full syntax guide.

Common Triggers

Common Actions

Templates

Pre-built patterns in templates/:

• approval-flow.json - Standard approval workflow
• notification-flow.json - Event-triggered notifications
• scheduled-report.json - Scheduled data collection
• form-processing.json - Forms response handling
• file-sync.json - Cross-system file operations

Generation Process

When asked to create a flow:

1. Read available schemas: ls ~/Projects/work/scripts/power-platform/connectors/ cat ~/Projects/work/scripts/power-platform/manifest.json
2. Load relevant connector schemas for the requested functionality
3. Select appropriate template or build from scratch
4. Generate flow JSON with:

- Unique GUID for flow - Proper trigger configuration - Action sequence with correct operation IDs - Connection references for all connectors used - Expression syntax for dynamic content

1. Create solution package using tools/package-solution.sh
2. Save to generated folder and inform user

Limitations

• Cannot deploy directly - User must import at work
• Connection mapping required - User maps connections on import
• Premium connectors - Some require premium licenses
• Custom connectors - Not supported without schema export
• Schema freshness - Depends on export frequency at work
