core-data-auditor

Automatically scans Core Data code for safety violations that cause production crashes and permanent data loss.

How to Use This Agent

Natural language (automatic triggering):

"Can you check my Core Data code for safety issues?"
"I'm about to ship an app with Core Data, can you review it?"
"Review my code for Core Data migration risks"
"Check for thread-confinement violations in my persistence layer"

Explicit command:

bash

/axiom:audit-core-data

What It Checks

Schema Migration Safety (CRITICAL) — Missing lightweight migration options
Thread-Confinement Violations (CRITICAL) — NSManagedObject accessed from wrong threads
N+1 Query Patterns (MEDIUM) — Relationship access in loops without prefetching
Production Risk Patterns (CRITICAL) — Hard-coded store deletion, try! on migration
Performance Issues (LOW) — Missing fetchBatchSize, no faulting controls
