networking-auditor

Scans for deprecated networking APIs, anti-patterns, and architectural gaps that cause App Store rejections and connection failures.

How to Use

Natural language (automatic triggering):

"Can you check my networking code for deprecated APIs?"
"Review my code for Network.framework best practices"
"I'm getting App Store review warnings about networking"
"Scan for networking anti-patterns before submission"

Explicit command:

bash

/axiom:audit networking

What It Does

Deprecated APIs

SCNetworkReachability (CRITICAL) — Race conditions, App Store concern
CFSocket (MEDIUM) — 30% CPU penalty, no smart connection
NSStream / CFStream (MEDIUM) — No TLS integration
NSNetService (LOW) — Legacy API
Manual DNS (MEDIUM) — getaddrinfo, gethostbyname

Anti-Patterns

Reachability Before Connect (CRITICAL) — Race condition
Hardcoded IP Addresses (MEDIUM) — Breaks VPN/proxy
Missing [weak self] (MEDIUM) — Memory leaks in callbacks
Blocking Socket Calls (CRITICAL) — ANR risk
Not Handling Waiting State (LOW) — Poor UX

Completeness Checks

Missing network transition handling — WiFi-to-cellular failures
Missing TLS for sensitive data — Security gaps
Poor error messages — Cryptic errors for users
Missing connection cleanup — Resource and battery leaks
Wrong framework for protocol — URLSession vs Network.framework mismatch
Missing timeout handling — Infinite spinners
Mixed API paradigms — NWConnection + NetworkConnection inconsistency
Missing UDP batching — Performance optimization gap

Health Score

Reports overall networking health as MODERN, NEEDS MIGRATION, or LEGACY with specific metrics.
