Triage an Apple crash report (.ips) using the crashdx CLI. Symbolicate, get an evidence-cited diagnosis with ranked hypotheses, and walk the verdict back to a code fix. Use whenever the user has a crash report, .ips file, TestFlight/user-submitted crash, or asks why their app crashed.
Debug a logic bug (wrong output, wrong value, incorrect behavior) using rr. Sets breakpoints at the point where the bug is observable, then reverse-executes to find where the computation went wrong.
Debug a data race or concurrency bug using rr. Records the program, then uses deterministic replay with thread inspection and watchpoints to find the exact interleaving that caused the race.
Orchestrator that dispatches every Proxyfan specialist skill in parallel and folds their findings into one prioritised, deduplicated action plan. Works for whole-codebase analysis and for PR / branch / working-tree diffs.
Cross-file structural-duplication specialist for Proxyfan — catches parallel implementations, branch explosions, adapter accumulation, and the fragmentation that creeps in when narrow edits accumulate beside an existing abstraction.
Domain-modelling specialist for Proxyfan — evaluates bounded-context integrity, aggregate boundaries, anemic models, ubiquitous-language drift, and infrastructure contamination of the domain.
