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 | $0.00038 | $0.01394 |
| Opus 5 | $0.00019 | $0.00697 |
| Sonnet 5 | $0.00008 | $0.00279 |
| Haiku 4.5 | $0.00004 | $0.00139 |
Grade C, and why
mapbox-navigation-patterns scanned grade C with 1 finding 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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
**Before coding:** SPM (`MapboxNavigationCore` + `MapboxNavigationUIKit`), `.netrc` download token, `MBXAccessToken`, location permissions, background `audio`/`location` — see [install guide](https://docs.mapbox.com/ios/ How it starts

Mapbox Navigation Patterns
Expert guidance for implementing navigation and routing features using Mapbox Directions API and Navigation SDKs. Covers turn-by-turn navigation, route optimization, real-time traffic integration, multi-stop routing, and navigation UI components.
Use This Skill When
User says things like:
- "I need turn-by-turn navigation in my app"
- "How do I add driving directions?"
- "I want to show a route on the map"
- "I need multi-stop routing"
- "How do I add voice guidance?"
- "I want real-time traffic updates"
- "I need to optimize delivery routes"
Product Overview
Directions API (REST)
Best for: Web applications, simple routing, backend route calculation
Features:
- Route calculation (driving, walking, cycling, traffic)
- Alternative routes
- Turn-by-turn instructions
- Multi-stop routing (up to 25 waypoints)
- Route optimization
- Real-time traffic data
- Avoid specific roads/areas
Pricing: Pay per request
Navigation SDK for iOS
Best for: Native iOS apps with turn-by-turn navigation
Defaults: SwiftUI app shell + wrap drop-in NavigationViewController via UIViewControllerRepresentable (official getting-started path). Use a fully custom Core UI (CoreSDKExample) only when the user explicitly wants to build their own nav chrome.
Before coding: SPM (MapboxNavigationCore + MapboxNavigationUIKit), .netrc download token, MBXAccessToken, location permissions, background audio/location — see install guide and the iOS reference checklist.
Features:
- Drop-in turn-by-turn UI (
NavigationViewController) — default - Optional fully custom Core UI (route progress / banner publishers)
- Voice guidance (30+ languages)
- Real-time rerouting
- Traffic-aware routing
- Offline maps and routing
- Route progress tracking
- Speed limit display
Pricing: Monthly Active Users (MAU) based
What ships with it
8 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-navigation-patterns is a skill published in the GitHub repository mapbox/mapbox-agent-skills (74 stars, last pushed 7d ago), licensed MIT. It adds 38 tokens to every session and 1,394 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

edge-to-edge
Use this skill to migrate your Jetpack Compose app to add adaptive edge-to-edge support and troubleshoot common issues. Use this skill to fix UI components (like buttons or lists) that are obscured by or overlapping with the navigation bar or status bar, fix IME insets, and fix system bar legibility.
dogfood
Systematically explore and test a mobile app on iOS/Android with agent-device to find bugs, UX issues, and other problems. Use when asked to dogfood, QA, exploratory test, find issues, bug hunt, or test this app on mobile.

Fixes Flutter layout errors (overflows, unbounded constraints) using Dart and Flutter MCP tools. Use when addressing "RenderFlex overflowed", "Vertical viewport was given unbounded height", or similar layout issues.
referral-program
When the user wants to design, launch, or optimize an in-app referral / invite / share-to-earn program — including reward structure, mechanics, fraud prevention, deep link setup, and viral coefficient measurement. Use when the user mentions "referral program", "invite a friend", "refer and earn", "share to earn"…
