Debugging Log Analyser Skill

Parses raw error logs, stack traces, and crash reports into a structured diagnosis with probable root cause, affected code path, and specific next steps — no hand-waving.

Required Inputs

Ask for these if not provided:

• 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)

Output Format

---

Debugging Report: [Service/App Name]

1. Error Classification

Error type: [Runtime exception / Build error / Config error / Network error / Memory error / Unknown] Severity: [Fatal / Critical / Warning / Informational] Recurrence pattern: [One-off / Intermittent / Consistent / On-startup / Under load]

2. Stack Trace Analysis

Walk the stack frame by frame, starting from the origin:

• Origin frame: [File, line, function where it started]
• Propagation path: [How it travelled through the call stack]
• Crash point: [Where it ultimately threw/panicked/exited]

For each significant frame, note whether it is:

• User code (fixable here)
• Framework/library code (usually a misuse issue)
• System/runtime code (usually a config or environment issue)

3. Root Cause Assessment

Probable root cause: [1–2 sentence plain English statement] Confidence: [High / Medium / Low — and why] Alternative causes to rule out: [If confidence is not high]
