Total: 164 skills across 23 categories (single-skill categories count their category file; other index files aren't counted — enforced by scripts/check-counts.sh in CI)

Quick Start

How to Use

No idea yet? Say: "I don't know what to build"

New app? Say: "I have an idea for a macOS app that does X. Should I build it?"

Existing app? Say: "Review my code" or "Add [feature]"

See docs/USAGE.md for complete guide.

Install as a Plugin (recommended)

In Claude Code:

/plugin marketplace add rshankras/claude-code-apple-skills
/plugin install apple-skills@indie-apple-stack

This surfaces the library as 23 category skills (/apple-skills:generators, /apple-skills:testing, ...); each category skill routes to its sub-skills on demand, so only 23 short descriptions sit in context. Update any time with /plugin marketplace update indie-apple-stack — no version pinning, you always track main.

Want the full workflow too? The same marketplace carries SwiftShip — 53 /apple:* commands:

/plugin install apple@indie-apple-stack

Manual Install (copy)

# Clone
git clone https://github.com/rshankras/claude-code-apple-skills.git

# Copy to your project
cp -r claude-code-apple-skills/skills your-project/.claude/skills/

# Or install globally
cp -r claude-code-apple-skills/skills ~/.claude/skills/

Pinning and rollback

Plugin installs track main with no version pinning. If you need a stable snapshot, annotated era tags mark each WWDC content boundary (see CHANGELOG.md): git clone --branch wwdc25-era-final https://github.com/rshankras/claude-code-apple-skills.git and copy skills/ manually as above.
