macOS Shortcuts Generator

Generate valid .shortcut files that can be signed and imported into Apple's Shortcuts app.

Quick Start

A shortcut is a binary plist with this structure:

xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

Core Concepts

1. Actions

Every action has:

  • Identifier: is.workflow.actions.<name> (e.g., is.workflow.actions.showresult)
  • Parameters: Action-specific configuration in WFWorkflowActionParameters
  • UUID: Unique identifier for referencing this action's output

2. Variable References

To use output from a previous action:

  1. The source action needs a UUID parameter
  2. Reference it using OutputUUID in an attachmentsByRange dictionary
  3. Use (U+FFFC) as placeholder in the string where the variable goes
  4. Set WFSerializationType to WFTextTokenString

3. Control Flow

Control flow actions (repeat, conditional, menu) use:

  • GroupingIdentifier: UUID linking start/middle/end actions
  • WFControlFlowMode: 0=start, 1=middle (else/case), 2=end

Signing Shortcuts

Shortcuts MUST be signed before they can be imported. Use the macOS shortcuts CLI:

bash
# Sign for anyone to use
shortcuts sign --mode anyone --input MyShortcut.shortcut --output MyShortcut_signed.shortcut

# Sign for people who know you
shortcuts sign --mode people-who-know-me --input MyShortcut.shortcut --output MyShortcut_signed.shortcut

The signing process:

  1. Write your plist as XML to a .shortcut file
  2. Run shortcuts sign to add cryptographic signature (~19KB added)
  3. The signed file can be opened/imported into Shortcuts.app

Workflow for Creating Shortcuts

  1. Define actions - List what the shortcut should do
  2. Generate UUIDs - Each action that produces output needs a unique UUID
  3. Build action array - Create each action dictionary with identifier and parameters
  4. Wire variable references - Connect outputs to inputs using OutputUUID
  5. Wrap in plist - Add the root structure with icon, name, version
  6. Write to file - Save as .shortcut (XML plist format is fine)
  7. Sign - Run shortcuts sign to make it importable

Key Rules

  1. UUIDs must be uppercase: A1B2C3D4-E5F6-7890-ABCD-EF1234567890
  2. WFControlFlowMode is an integer: Use <integer>0</integer> not <string>0</string>
  3. Range keys use format: {position, length} - e.g., {0, 1} for first character
  4. The placeholder character: (U+FFFC) marks where variables are inserted
  5. Control flow needs matching ends: Every repeat/if/menu start needs an end action with same GroupingIdentifier
