Description
Set up error tracking with actionable context. Use when configuring error capture or error boundaries.

Error Tracking

Capture errors with the context needed to debug them.

Core Principle

An error without context is useless. Every error should include:

| Context | Why | Example | |---------|-----|---------| | route | Where it happened | "/checkout" | | job_name | What user was doing | "checkout" | | job_step | Where in the flow | "payment" | | user_segment | Who's affected | "premium" | | app_version | Release correlation | "1.2.3" |

Error Types to Capture

| Type | Capture Method | |------|----------------| | Unhandled exceptions | window.onerror, SDK auto-capture | | Promise rejections | window.onunhandledrejection | | Component errors | Error boundaries | | Async/await errors | try/catch with context | | API errors | Fetch/axios interceptors |

What NOT to Include

| Don't | Why | |-------|-----| | Passwords | Security | | Email/phone | PII | | Full request bodies | PII, size limits | | Entire app state | Unbounded | | Localized messages | Breaks grouping |

Implementation

See templates/error-boundary.tsx for React error boundary with telemetry.

Use Read tool to load template when generating implementation.

Anti-Patterns

See references/anti-patterns.md for common error tracking mistakes.
