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.
