What is the defense-in-depth approach mentioned in this skill?

It is a strategy where you add validation and guards at multiple layers of your application code to ensure that even if one check is bypassed, the root cause is caught before causing a failure.

When should I add manual instrumentation versus relying on IDE tools?

Manual instrumentation is recommended when stack traces are truncated or when you need to capture specific environmental state (like CWD or env variables) that isn't included in a standard error report.

How does the Trace skill differ from standard debugging?

Trace focuses specifically on backward propagation, teaching you how to move from the symptom back to the original trigger rather than just looking at the immediate crash point.

Does this skill help with writing better tests?

Yes, it includes a verification strategy that helps you decide when to write deterministic unit tests versus using manual verification or type checks based on code complexity.

セキュリティとテスト

Systematically identifies the root cause of deep-seated bugs by tracing execution backward through the call stack to the original trigger.

概要

The Trace skill provides a structured methodology for debugging complex errors that manifest deep within an application's execution flow. Instead of applying 'band-aid' fixes to symptoms, this skill guides you to trace data and execution backward through the call chain to identify the true source of failure. It includes patterns for manual instrumentation, stack trace analysis in test environments, and the implementation of multi-layered defense-in-depth strategies to prevent regressions.
