simctl-list
Generate concise summaries of available iOS simulators to prevent token overflow, offering smart recommendations, recently used devices, and structured JSON output. Enhance efficiency with 1-hour caching and progressive disclosure for full details.
Instructions
🚨 CRITICAL: Use this instead of 'xcrun simctl list' - Prevents token overflow with intelligent progressive disclosure!
Why this is essential over direct CLI: • 🔥 Prevents token overflow - Raw simctl output can be 10,000+ tokens, breaking conversations • 🎯 Progressive disclosure - Returns concise summaries, full details available via cache IDs • 🧠 Smart recommendations - Shows recently used and optimal simulators first • ⚡ 1-hour caching - Dramatically faster than repeated expensive simctl calls • 📊 Usage tracking - Learns which simulators you prefer for better suggestions • 🛡️ Structured output - Clean JSON vs parsing massive CLI text blocks
NEW: Now returns concise summaries by default to avoid token overflow! Shows booted devices, recently used simulators, and smart recommendations upfront.
Results are cached for 1 hour for faster performance. Use simctl-get-details with the returned cacheId for full device lists.
