ux-network

ux-network is a skill for Claude Code, Codex from parhamb/design-skills. It costs 45 tokens per session (772 once invoked), scanned A, original, MIT.

Guidance for designing how an app behaves when the internet is slow, interrupted, or unavailable. It covers offline use, cached content, background syncing, and connection errors.

In plain words
What is it for?
Use it to review offline mode, retry messages, caching, queued changes, background data syncing, and switching between Wi-Fi and mobile data.
Why use it?
It prevents users from seeing blank screens, losing work, or having the app fail when network conditions change. It helps the app remain understandable and usable on weak connections.

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

ux-network 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 and Connectivity UX

Network conditions are unpredictable. An app that only works on fast Wi-Fi is not a reliable product. Design for the worst connection and fast connections will take care of themselves.


Checklist

Item Guidance
Performance on slow connections Critical content loads first. Images lazy-load. API payloads are compressed.
No internet error Inline message with a retry button. Never an empty screen with no explanation.
Network switch resilience App does not crash or disconnect when switching from Wi-Fi to mobile data.
Offline mode Cached content is displayed. Writes are queued and flushed when connection returns.
Background data sync Data syncs in background on Wi-Fi by default. User can enable sync over mobile data.

Offline-First Architecture

Optimistic UI: Update the UI immediately to show the expected outcome, then sync in the background. If the sync fails, show an undo option. This approach makes the app feel fast regardless of network speed.

Cache strategies:

  • Stale-while-revalidate: Show cached content immediately, refresh in the background.
  • Cache-first: Always show the cache, refresh only on explicit pull-to-refresh.
  • Network-first: Try the network first, fall back to cache on failure.

Sync queue: Store pending writes locally and flush them when connectivity returns. Show a clear sync status indicator so users know their changes are queued and will be saved.


Error State Patterns

Scenario UI Pattern
No internet at launch Full-screen message with an illustration and a Retry button
Lost internet mid-use Top banner: "No connection — working offline"
Slow connection Skeleton screens instead of spinners
Server error (5xx) "Something went wrong on our end." with a Retry button
Request timeout "Taking longer than usual." with Keep waiting and Cancel options
Partial failure Load what worked, show an inline error for what failed

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.
