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 | $0.00038 | $0.01381 |
| Opus 5.5 | $0.00015 | $0.00552 |
| Sonnet 5.5 | $0.00008 | $0.00276 |
| Haiku 4.5 | $0.00004 | $0.00138 |
Grade A, and why
network-connectivity 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 1mo 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 Connectivity
Global network connectivity monitoring with automatic offline banner display. Uses smart detection that combines connectivity_plus status with actual API request success to avoid false negatives from government blocks or captive portals.
When to Use This Skill
- Adding network connectivity monitoring to an app
- Implementing a global offline banner/indicator
- Setting up connectivity-aware features
- User asks "offline banner", "network status", "connectivity monitoring"
When NOT to Use This Skill
- Error handling for failed API calls - Use
/datawhich hasNetworkFailuretypes - Retry logic - Handled in repository layer via
/datapatterns - Offline data caching - Use
/datacaching patterns - NetworkFailure types - Already in
/coreerrors/failures.dart
Quick Reference
Dependencies
dependencies:
connectivity_plus: ^6.0.0
Core Components
| Component | Purpose |
|---|---|
ConnectivityService |
Wraps connectivity_plus, provides stream |
ActualConnectivity |
Smart notifier combining library + API success |
ConnectivityInterceptor |
Dio interceptor reporting request success |
ConnectivityBanner |
Global overlay widget for offline banner |
ConnectivityWrapper |
Root widget that manages banner display |
Smart Detection
The connectivity_plus library can report false negatives when:
- Government blocks connectivity check endpoints
- Captive portals intercept requests
- DNS issues affect only certain domains
Solution: If any real API request succeeds, override "offline" status.
| Scenario | Library Says | API Result | Actual Status |
|---|---|---|---|
| Normal online | online | success | online |
| Normal offline | offline | fails | offline |
| Blocked endpoints | offline | success | online |
| Captive portal | online | fails | online (until timeout) |
Connectivity States
| State | Meaning | UI Action |
|---|---|---|
wifi |
Connected via WiFi | Hide banner |
mobile |
Connected via mobile data | Hide banner |
ethernet |
Connected via ethernet | Hide banner |
none |
No connectivity | Show banner |
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 1mo ago First seen · 200 lines · 38 tokens per session scan A 78888c7ba31a
network-connectivity is a skill published in the GitHub repository launch52-ai/flutter-template (2 stars, last pushed 7mo ago), licensed MIT. It adds 38 tokens to every session and 1,381 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
