Summary

Overall risk is low. The material indicates an open-source project with very strong community adoption and no credential requirement; the main watchpoints are optional internet use via the Iconify API and the read/write semantics around local project icon asset generation mentioned in the README.

CredentialsLow risk

The material explicitly states there are no required keys or environment variables. No API token, account credential, or sensitive system authentication is requested, so credential exposure and abuse risk appears low.

Network egressCaution

The README mentions optional searching and generation through the Iconify API, indicating potential network egress. Although no specific host is listed, the transmitted data appears limited to icon search terms, collection prefixes, and icon identifiers rather than obviously sensitive content, but the network behavior still warrants attention.

Code executionLow risk

The system flags this as prompt-only, and there is no declared need for daemons, privilege escalation, persistent background services, or broad system control. While the README shows shell/swift example commands, the audit material does not demonstrate execution privileges beyond the icon-generation use case.

Data accessCaution

The material describes generating PNG imagesets for Xcode asset catalogs and suggests checking or replacing existing project icons, implying expected read/write access to user-specified asset directories. No excessive data access beyond that purpose is evident, but project file modifications should remain tightly scoped.

Supply chainLow risk

The source is an open-source GitHub repository with extremely strong community adoption (about 210k stars), which materially lowers supply-chain opacity risk. The missing license declaration and unknown maintenance status are minor audit gaps, but not enough to raise this to high risk based on the current material.

Recommendations

If internet-based search is needed, verify the actual Iconify API domain and use it within a controlled network environment.
Restrict the output path to the project asset directory to avoid overwriting unrelated files.
Review the repository source and scripts first to confirm they only perform icon-generation logic.
Inspect generated imagesets before committing to ensure no unexpected files or unnecessary metadata were introduced.

Generate SF Symbols icon assets

Prompt

Use SF Symbols to generate a PNG imageset for a 'favorites' icon for my iOS app. Keep the style minimal, make it compatible with the Xcode asset catalog, and list the generated sizes and filenames.

Expected

A set of Xcode-ready PNG icon assets with size and filename details.

Search and generate open-source icons

Prompt

Search Iconify for icons suitable for 'user settings', give me 5 options, and generate an iOS-ready PNG imageset for the one I choose.

Expected

Several icon candidates and an iOS PNG asset set for the selected icon.

Batch create app icon assets

Prompt

Batch generate PNG imagesets for four iOS tab bar icons: Home, Search, Notifications, and Profile. Keep the style consistent and ready to add to the asset catalog.

Expected

A consistent set of multi-size icon assets ready to import into an Xcode project.

iOS Icon Generator

Generate PNG icon imagesets for Xcode asset catalogs from two sources.

When to Activate

Generating icon assets for an iOS/macOS Xcode project
Searching for icons across open source collections
Creating PNG imagesets (1x, 2x, 3x) for asset catalogs
Replacing placeholder icons with production-quality assets
Matching existing icon styles in an Xcode project

Core Principles

1. Two Sources, One Output Format

Both sources produce identical Xcode-compatible imagesets. Choose based on need:

Source	Icons	Requires	Best for
Iconify API	275,000+ from 200+ collections	Internet	Wide selection, specific styles, open source icons
SF Symbols	5,000+ Apple symbols	macOS only	Apple-native style, offline use

2. Always Match Existing Style

Before generating, check the project's existing icons for size, color, and weight consistency.

3. Output Structure

Both methods produce a complete Xcode imageset:

<output-dir>/<asset-name>.imageset/
  Contents.json
  <asset-name>.png        # 1x (68px default)
  <asset-name>@2x.png     # 2x (136px default)
  <asset-name>@3x.png     # 3x (204px default)

Examples

Step 1: Assess Requirements

Determine icon needs: what the icon represents, preferred style, target color, and size.

If the project already has icons, check existing style:

# Check dimensions of existing icon
sips -g pixelWidth -g pixelHeight path/to/[email protected]

Step 2: Search for Icons

Iconify API (recommended for wide selection):

# Search all collections
$SKILL_DIR/scripts/iconify_gen.sh search "receipt"

# Search within a specific collection
$SKILL_DIR/scripts/iconify_gen.sh search "business card" --prefix mdi

# List available collections
$SKILL_DIR/scripts/iconify_gen.sh collections

SF Symbols (for Apple-native style): Browse the SF Symbols app or reference common names:

Use Case	Symbol Name
Document	`doc.text`, `doc.fill`
Receipt	`doc.text.below.ecg`, `receipt`
Person	`person.crop.rectangle`, `person.text.rectangle`
Camera	`camera`, `camera.fill`
Scan	`doc.viewfinder`, `qrcode.viewfinder`
Settings	`gearshape`, `slider.horizontal.3`

Step 3: Preview (Optional)

# Iconify preview
$SKILL_DIR/scripts/iconify_gen.sh preview mdi:receipt-text-outline

Step 4: Generate

Iconify API:

# Basic generation
$SKILL_DIR/scripts/iconify_gen.sh mdi:receipt-text-outline editTool_expenseReport

# Custom color and output location
$SKILL_DIR/scripts/iconify_gen.sh mdi:receipt-text-outline myIcon --color 007AFF --output ./Assets.xcassets/icons

Options: --size <pt> (default: 68), --color <hex> (default: 8E8E93), --output <dir> (default: /tmp/icons)

SF Symbols:

# Basic generation
swift $SKILL_DIR/scripts/generate_icons.swift doc.text.below.ecg editTool_expenseReport

# Custom color, weight, and output
swift $SKILL_DIR/scripts/generate_icons.swift person.crop.rectangle myIcon --color 007AFF --weight regular --output ./Assets.xcassets/icons

Options: --size <pt> (default: 68), --color <hex> (default: 8E8E93), --weight <name> (default: thin), --output <dir> (default: /tmp/icons)

Step 5: Verify and Integrate

Read the generated @2x PNG to verify visually

Copy to asset catalog if not output there directly:

cp -r /tmp/icons/<name>.imageset path/to/Assets.xcassets/<group>/

Build the project to verify Xcode picks up the new assets

Popular Iconify Collections

Prefix	Name	Count	Style
`mdi`	Material Design Icons	7400+	Filled + outline variants
`ph`	Phosphor	9000+	6 weights per icon
`solar`	Solar	7400+	Bold, linear, outline
`tabler`	Tabler Icons	6000+	Consistent stroke width
`lucide`	Lucide	1700+	Clean, minimal
