How do I install the Networking skill?

Run npx skillmds@latest add caglarbaranbora/networking in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Networking safe to use?

This skill has not completed SkillMD's automated safety review yet. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Networking?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Networking free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Networking

Route URLSession networking implementation tasks to the correct Knowledge Contracts — request construction, async/await and completion-handler data fetching, Codable decoding, HTTP error handling, task cancellation, session configuration, App Transport Security, authenticated requests, session delegates and their invalidation, background transfers, progress reporting, authentication challenges, server trust and certificate pinning, and Combine's dataTaskPublisher. Use when writing or reviewing code that makes an HTTP request, decodes a JSON response, handles a network error, downloads a file in the background, reports transfer progress, or answers a TLS or credential challenge in Swift. Sign-in UX/terminology is out of scope here — see the authenticationservices skill. Triggers on URLSession, URLRequest, URLComponents, async await network call, data(for:), bytes(for:), dataTask, completionHandler, resume(), withCheckedThrowingContinuation, JSONDecoder, Codable decoding, DecodingError, HTTPURLResponse, URLErro

Networking — Foundations Skill

Purpose

Route URLSession networking implementation tasks to the minimum required Networking Knowledge Contracts — the async/await request path, the delegate-driven surface built on top of it, and the two older API families (completion handlers, Combine) an existing codebase may already be using.

Routing

Load only the contracts relevant to the task. All paths relative to knowledge/networking/.

Requests -> url-request-construction.md, async-data-fetching.md, url-session-configuration.md
Data handling -> codable-decoding.md, http-error-handling.md
Lifecycle -> task-cancellation.md
Security & auth -> app-transport-security.md, authenticated-requests.md
Delegates -> url-session-delegate.md (URLSessionDelegate, invalidation, delegate queue), background-transfers.md (background(withIdentifier:), handleEventsForBackgroundURLSession, didFinishDownloadingTo), transfer-progress-tracking.md (didWriteData, didSendBodyData, Task.progress)
Server challenges -> authentication-challenges.md (URLAuthenticationChallenge, AuthChallengeDisposition, URLCredential), server-trust-evaluation.md (serverTrust, certificate pinning)
Older API families -> completion-handler-apis.md (dataTask completionHandler, resume(), continuation bridging), data-task-publisher.md (Combine dataTaskPublisher)

Never load more than the contracts relevant to the specific question. For the sign-in mechanism itself, route to skill.authenticationservices.foundations, and for its wording to skill.style-guide.writing — this Skill covers only the networking mechanics of attaching credentials to a request.

Stop Conditions

Stop and report if the requested topic has no matching Knowledge Contract in knowledge/networking/ — do not guess or fall back to general knowledge.

BGTaskScheduler background work, as opposed to background transfers — owned by backgroundtasks
Rendering a progress control or a credential prompt — owned by human-interface-guidelines
Keychain storage of a credential marked .permanent — Excluded
Writing a custom URLProtocol subclass — Excluded
