Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.09388 |
| Opus 5 | $0.00028 | $0.04694 |
| Sonnet 5 | $0.00011 | $0.01878 |
| Haiku 4.5 | $0.00006 | $0.00939 |
Grade A, and why
axiom-network-framework-ref 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 4d 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 API Reference
Overview
Network.framework is Apple's modern networking API that replaces Berkeley sockets, providing smart connection establishment, user-space networking, built-in TLS support, and seamless mobility. Introduced in iOS 12 (2018) with NWConnection and evolved in iOS 26 (2025) with NetworkConnection for structured concurrency.
Evolution timeline
- 2018 (iOS 12) NWConnection with completion handlers, deprecates CFSocket/NSStream/SCNetworkReachability
- 2019 (iOS 13) User-space networking (30% CPU reduction), TLS 1.3 default
- 2025 (iOS 26) NetworkConnection with async/await, TLV framing built-in, Coder protocol, Wi-Fi Aware discovery
Key capabilities
- Smart connection establishment Happy Eyeballs (IPv4/IPv6 racing), proxy evaluation (PAC), VPN detection, WiFi Assist fallback
- User-space networking ~30% lower CPU usage vs sockets, memory-mapped regions, reduced context switches
- Built-in security TLS 1.3 by default, DTLS for UDP, certificate pinning support
- Mobility Automatic network transition handling (WiFi ↔ cellular), viability notifications, Multipath TCP
- Performance ECN (Explicit Congestion Notification), service class marking, TCP Fast Open, UDP batching
When to use vs URLSession
- URLSession HTTP, HTTPS, WebSocket, simple TCP/TLS streams → Use URLSession (optimized for these)
- Network.framework UDP, custom protocols, low-level control, peer-to-peer, gaming, streaming → Use Network.framework

When to Use This Skill
Use this skill when:
- Planning migration from BSD sockets, CFSocket, NSStream, or SCNetworkReachability
- Understanding API differences between NWConnection (iOS 12-25) and NetworkConnection (iOS 26+)
- Implementing all 12 WWDC 2025 examples (TLS connection, TLV framing, Coder protocol, NetworkListener, Wi-Fi Aware)
- Choosing protocols (TCP, UDP, TLS, QUIC) for your use case
- Peer-to-peer discovery setup with NetworkBrowser and Wi-Fi Aware
- Optimizing performance with user-space networking, batching, pacing
- Migrating from completion handlers to async/await (NWConnection → NetworkConnection)
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-network-framework-ref is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 55 tokens to every session and 9,388 once invoked, about $0.0003 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.

opensrc
Fetch dependency source code to give AI agents deeper implementation context. Use when the agent needs to understand how a library works internally, read source code for a package, fetch implementation details for a dependency, or explore how an npm/PyPI/crates.io package is built. Triggers include "fetch source for"…
background-script-execution
What actually happens when you call snowexecutescript — the Scripted REST endpoint Serac auto-deploys on first use, the scheduled-job fallback, what scheduledjobpending means, and how to get output back when the call comes home empty.
csdm-modeling
Pick the right ServiceNow service class under the Common Service Data Model — business service, service offering, application service, business application — and point the CMDB tools at it without creating the records CSDM tells customers to migrate away from.
inbound-email
Handle email arriving at a ServiceNow instance — inbound email action ordering and stop-processing, the real syseventinemailaction column names, and reading sysemail when a message created no record.
mcp-tool-discovery
Find and call tools on this ServiceNow MCP server — the two meta-tools it starts with, why a missing session id makes every other tool unreachable, which queries actually match, and which advertised tools are not on the server at all.
cmdb-patterns
Create ServiceNow CIs and cmdbrelci relationships, walk upstream/downstream impact, detect orphan/stale CIs, and align discovered CIs with the proper sysclassname hierarchy.
