# Mobile Observability Plugin Teaches Claude how to instrument mobile apps correctly — what to measure, what context to attach, and what mistakes to avoid. ## The Problem Most mobile teams instrument poorly: - **Too little** — Can't debug production issues - **Too much** — Noise, cost, battery drain - **Wrong context** — Errors without enough data to act on This plugin teaches Claude to capture both **user intent** (what they tried to do) and **system state** (device conditions, errors, performance) so you can answer *"Why did this fail, and for whom?"* ## Installation ```bash claude plugin marketplace add calube/mobile-observability claude plugin install mobile-observability ``` ## Usage ### Commands ``` /instrument ios /audit features/checkout ``` ### Natural Prompts ``` "How should I instrument this payment flow?" "What context should I attach to crashes?" "Set up session replay with Bitdrift" "Review this code for observability anti-patterns" "What's missing from our crash reporting setup?" ``` ## Commands | Command | Description | |---------|-------------| | `/instrument [platform]` | Generate prioritized instrumentation plan for iOS, Android, React Native, or Flutter | | `/audit [path]` | Scan existing code for instrumentation gaps and anti-patterns | ## Agents Agent definitions that Claude reads and follows when performing analysis tasks. ### codebase-analyzer Explores mobile codebases to understand architecture and identify instrumentation opportunities. **Focus Areas:** - Platform and architecture detection (MVVM, TCA, Clean Architecture) - Existing telemetry SDK inventory - Entry points and key user flows - Network, persistence, and state management layers **Output:** - Platform summary with language/version - Architecture pattern identification - Existing SDK coverage assessment - Gap analysis with priority ranking ### instrumentation-reviewer Reviews code changes for observability issues before they ship. **Focus Areas:** - Anti-patterns (PII leaks, high cardinality, sync telemetry) - Missing context (no user ID, no session, no screen) - Naming consistency - Vendor best practices **Output:** - Issues by severity with file:line references - Specific fixes with code examples - Vendor guideline references ## Skills 8 skills that activate automatically based on context: | Skill | Trigger | |-------|---------| | `instrumentation-planning` | "What should I measure?" | | `crash-instrumentation` | "How to capture crashes with context" | | `session-replay` | "Set up session replay" | | `interaction-latency` | "Track button response time" | | `navigation-latency` | "Track screen load time" | | `network-tracing` | "Trace API requests" | | `user-journey-tracking` | "Track user funnels" | | `symbolication-setup` | "Configure dSYM upload" | ## When to Use **Use this plugin for:** - Adding observability to a new or existing mobile app - Setting up crash reporting, performance monitoring, or session replay - Choosing between vendors (Sentry, Datadog, Embrace, Bitdrift, Firebase, New Relic, etc.) - Reviewing instrumentation code for anti-patterns - Understanding what context to attach to errors **Don't use for:** - Backend/server observability - Web frontend (different patterns) - General logging questions unrelated to mobile ## Directory Structure ``` mobile-observability/ ├── commands/ # /instrument, /audit ├── agents/ # codebase-analyzer, instrumentation-reviewer ├── skills/ # 8 instrumentation skills ├── hooks/ # Anti-pattern warnings for Swift/Kotlin/TypeScript/Dart └── references/ # 25+ guides covering methodology, platforms, vendors ``` ## Philosophy 1. **Start with crashes** — Get crash reporting and symbolication right before adding anything else 2. **Context over volume** — One error with full context beats 100 without 3. **User intent + system state** — Link what users tried to do with device conditions (memory, network, battery) 4. **Avoid anti-patterns early** — PII leaks and high cardinality are expensive to fix later ## Author [Caleb Davis](https://github.com/calube) ## License MIT — see [LICENSE](LICENSE)
