Hunt iOS memory leaks and investigate runtime performance from inside Claude Code. memorydetective bundles an MCP server with 28 tools for analyzing .memgraph and .trace files, plus a /perf-investigate skill that routes you to the right playbook based on symptoms (leak, hang, jank, slow launch). Key features: - 34-pattern retain-cycle classifier covering SwiftUI (incl. @Observable, SwiftData, NavigationStack), Swift Concurrency, Combine, UIKit, Core Data, RxSwift, Realm, and Coordinator pattern - Every classification ships fixHint + staticAnalysisHint + a Swift before/after fixTemplate snippet - Trace analysis: hangs, animation hitches, allocations, app launch, time profile - compareTracesByPattern for CI gating against perf regressions - 5 SourceKit-LSP-backed Swift source-bridging tools (find references, hover, definitions) - macOS unified logging (logShow / logStream) - 5 slash commands for direct invocation: /investigate-leak, /investigate-hangs, /investigate-jank, /investigate-launch, /verify-cycle-fix Reads memgraphs exported from Xcode's Memory Graph Debugger and traces from xctrace. Ships as both a Claude Code plugin and a standalone npm package, so the same MCP server works in Cursor, Cline, Claude Desktop, and Continue.
