* feat: add ios-icon-gen skill for Xcode asset catalog icon generation
Add a skill that generates PNG icon imagesets (1x, 2x, 3x) for Xcode
asset catalogs from two sources:
- Iconify API: 275k+ open source icons from 200+ collections
(Material Design, Phosphor, Tabler, Lucide, etc.)
- SF Symbols: 5k+ Apple-native symbols (macOS only)
Includes search, preview, and generation scripts with customizable
size, color, weight, and direct output to asset catalogs.
* fix: address PR review feedback for ios-icon-gen skill
Security:
- Fix shell injection in iconify_gen.sh by passing query via sys.argv
instead of interpolating into Python string literal
Robustness:
- Replace all try!/force-unwrap with do/try/catch and guard let in
generate_icons.swift for graceful error handling
- Add option value validation (require_value/requireOptionValue) in
both scripts to prevent crashes on missing flag values
- Add curl timeouts (--connect-timeout 10, --max-time 30) to all
network calls
- Add sips conversion failure warnings instead of silent suppression
- Add error handling for curl in list_collections
Documentation:
- Rename SKILL.md sections to "When to Use", "How It Works", "Examples"
to match repo conventions
* fix: restore canonical SKILL.md headers and validate color/weight CLI inputs
- Revert SKILL.md section headers back to "When to Activate" and
"Core Principles" per CONTRIBUTING.md and SKILL-DEVELOPMENT-GUIDE.md
(the prior rename to "When to Use"/"How It Works" was incorrect)
- Validate --color as a 6-digit hex code at parse time instead of
silently falling back to the default gray
- Validate --weight against the known set of font weights instead of
silently falling back to thin
