Error Handling Analysis

What problem does it solve?

This framework provides a structured approach to evaluate and improve how a codebase handles errors, focusing on debuggability, user experience, and resilience during failures.

Core Features & Use Cases

• Guided error capture and propagation criteria: assess where errors are caught, preserved context, and how failures are surfaced.
• Error types, codes, and consistency: review the taxonomy of errors and ensure uniform handling across modules.
• User-facing messages and API responses: ensure messages are actionable, non-technical for users, and include actionable details for developers.
• Observability and logging guidance: prescribe structured logs, correlation IDs, and appropriate log levels to trace failures.
• Recovery patterns and testability: define retry, fallback, and circuit-breaker strategies; enable verifiable test coverage.
• Use Case examples: apply the framework to audits of REST APIs, UI components, and background jobs to demonstrate improvements.

Quick Start

Use this framework to initiate an error-handling audit on your project by following these steps:

• Step 1: Map error boundaries across frontend, backend, and services.
• Step 2: Apply the framework's criteria to identify gaps in error capture, messages, logging, and recovery.
• Step 3: Document findings in a structured report and implement recommended changes, then re-audit.
