axiom-networking-migration

axiom-networking-migration is a skill for Claude Code, Codex from ComeOnOliver/skillshub. It costs 43 tokens per session (2,048 once invoked), scanned A, original, MIT.

Migration guidance for moving between Apple networking APIs, including BSD sockets, NWConnection, URLSession streams, and NetworkConnection.

In plain words
What is it for?
Use it to modernize an iOS networking layer or decide whether an existing implementation should stay with URLSession.
Why use it?
It helps choose the right replacement while avoiding unnecessary migrations, deprecated APIs, and using custom-networking tools for ordinary web requests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

axiom-networking-migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Network Framework Migration Guides

Do I Need to Migrate?

What networking API are you using?

├─ URLSession for HTTP/HTTPS REST APIs?
│   └─ Stay with URLSession — it's the RIGHT tool for HTTP
│      URLSession handles caching, cookies, auth challenges,
│      HTTP/2/3, and is heavily optimized for web APIs.
│      Network.framework is for custom protocols, NOT HTTP.
│
├─ BSD Sockets (socket, connect, send, recv)?
│   └─ Migrate to NWConnection (iOS 12+)
│      → See Migration 1 below
│
├─ NWConnection / NWListener?
│   ├─ Need async/await? → Migrate to NetworkConnection (iOS 26+)
│   │   → See Migration 2 below
│   └─ Callback-based code working fine? → Stay (not deprecated)
│
├─ URLSession StreamTask for TCP/TLS?
│   └─ Need UDP or custom protocols? → NetworkConnection
│      Need just TCP/TLS for HTTP? → Stay with URLSession
│      → See Migration 3 below
│
├─ SCNetworkReachability?
│   └─ DEPRECATED — Replace with NWPathMonitor (iOS 12+)
│      let monitor = NWPathMonitor()
│      monitor.pathUpdateHandler = { path in
│          print(path.status == .satisfied ? "Online" : "Offline")
│      }
│
└─ CFSocket / NSStream?
    └─ DEPRECATED — Replace with NWConnection (iOS 12+)
       → See Migration 1 below

Migration 1: From BSD Sockets to NWConnection

Migration mapping

BSD Sockets NWConnection Notes
socket() + connect() NWConnection(host:port:using:) + start() Non-blocking by default
send() / sendto() connection.send(content:completion:) Async, returns immediately
recv() / recvfrom() connection.receive(minimumIncompleteLength:maximumLength:completion:) Async, returns immediately
bind() + listen() NWListener(using:on:) Automatic port binding
accept() listener.newConnectionHandler Callback for each connection
getaddrinfo() Let NWConnection handle DNS Smart resolution with racing
SCNetworkReachability connection.stateUpdateHandler waiting state No race conditions
setsockopt() NWParameters configuration Type-safe options

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

axiom-networking-migration is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 43 tokens to every session and 2,048 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
