Debugging Log Analyser

Q: How do I know the Debugging Log Analyser output is good?

The skill verifies itself against its own quality checks: Root cause is specific (not "there might be a null pointer issue"); At least one concrete code-level fix is suggested; Next steps are actionable commands, not vague advice; Suggested fix references the actual language/framework in the input (not a generic fix that could apply to any language).

Parse error logs, stack traces, and crash reports into a structured root cause diagnosis. Use when an application is throwing exceptions, crashing, or producing unexpected errors and you need to understand why and what to fix. Produces a structured diagnosis with error classification, stack trace walkthrough, probable root cause with confidence level, affected code path, a concrete code-level fix suggestion, and ordered next debugging steps.

What to give it

▸The log / stack trace / error output — paste directly or describe the error

▸Language and framework — e.g. Node.js + Express, Python + Django, Java Spring, Go

▸Context — what changed before this started — e.g. recent deploy, config change, increased traffic, new input data; or "nothing changed" is also useful

▸Frequency — one-off / intermittent / consistent / regression after a specific change

▸Environment — local dev / staging / production

▸What they've already tried — if anything

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Root cause is specific (not "there might be a null pointer issue")

✓At least one concrete code-level fix is suggested

✓Next steps are actionable commands, not vague advice

✓Suggested fix references the actual language/framework in the input (not a generic fix that could apply to any language)

✓Confidence level includes a stated reason (not just "High" or "Low" with no explanation)

✓Prevention is proactive (not just "add error handling")

⚠️ What it refuses to do

A vague root cause ("something's null somewhere") instead of the specific line/frame

A generic fix that could apply to any language, ignoring the actual stack trace

Restating the error message instead of explaining what it means

"Add error handling" as prevention, with no specific guardrail

High/Low confidence with no reason behind it
