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 | $0.00059 | $0.02312 |
| Opus 5 | $0.00030 | $0.01156 |
| Sonnet 5 | $0.00012 | $0.00462 |
| Haiku 4.5 | $0.00006 | $0.00231 |
Grade A, and why
mapbox-flutter-patterns 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 2d 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.

Mapbox Flutter Integration Patterns
Official patterns for integrating the Mapbox Maps SDK for Flutter (mapbox_maps_flutter) on iOS and Android with Dart.
Use this skill when:
- Installing and configuring mapbox_maps_flutter in a Flutter app
- Setting the Mapbox access token the right way
- Initializing a
MapWidgetwith camera / style options - Adding annotations (points, circles, lines, polygons) and handling taps
- Showing the user location puck
- Loading GeoJSON from app assets
- Troubleshooting iOS build failures after adding Mapbox
Official Resources:
Web and desktop are not supported — the Flutter SDK targets iOS and Android only.
Installation & Setup
Requirements
- Flutter SDK 3.22.3 / Dart 3.4.4+
- iOS: deployment target 14.0 or higher
- Android: minSdk 21 or higher
- Free Mapbox account
Step 1: Add the dependency
# pubspec.yaml
dependencies:
mapbox_maps_flutter: ^2.0.0
flutter pub get
Step 2: Bump the iOS deployment target to 14.0 (required)
This is the single most common cause of iOS build failures after adding Mapbox. The Flutter SDK requires iOS 14.0 and will not compile on the Flutter default.
-
Open
ios/Runner.xcworkspacein Xcode. -
Select the Runner target → General → set Minimum Deployments → iOS to
14.0. -
If
ios/Podfileexists, update the platform line too:# ios/Podfile platform :ios, '14.0'
You do not need to worry about CocoaPods vs Swift Package Manager — mapbox_maps_flutter supports both and Flutter picks whichever your app is configured for.
Step 3: iOS location permission
Add the purpose string to ios/Runner/Info.plist:
<key>NSLocationWhenInUseUsageDescription</key>
<string>Show your location on the map</string>
What ships with it
4 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.

mapbox-flutter-patterns is a skill published in the GitHub repository mapbox/mapbox-agent-skills (74 stars, last pushed 7d ago), licensed MIT. It adds 59 tokens to every session and 2,312 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 2026-08-30.
