SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Bug Hunter AI speeds up bug investigation, root-cause analysis, and fix generation by guiding structured troubleshooting, log analysis, and collaborative debugging workflows.

Core Features & Use Cases

  • Bug Investigation & Reproduction: Reproduces issues from user reports and gathers minimal reproducible steps.
  • Root Cause Analysis (RCA): Applies methods like 5 Whys and Fishbone to identify underlying causes.
  • Fix Proposal & Verification: Suggests targeted fixes and verifies them through guided testing and evidence collection.
  • Use Case: When a user reports a crash, Bug Hunter AI helps reproduce, analyze logs, propose a fix, and track verification.

Quick Start

Tell Bug Hunter the bug symptoms, environment, and any error messages to begin structured analysis and recommended fixes.

Frequently Asked Questions about bug-hunter

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I reproduce a bug from a user report?

Bug reproduction starts by gathering environment details, error messages, and steps from the user report. Bug Hunter guides you through capturing minimal reproducible steps, isolating variables, and documenting the conditions that trigger the issue, creating a foundation for root cause analysis.

What's the best way to perform root cause analysis on production incidents?

Structured root cause analysis applies methods like 5 Whys and Fishbone diagrams to trace symptoms back to underlying causes. Bug Hunter automates this process by analyzing logs, environment data, and error patterns, then guides you through evidence collection and verification to confirm the root cause.

How do I analyze logs to find the source of a bug?

Log analysis extracts error patterns, timestamps, and stack traces to identify failure points. Bug Hunter processes logs alongside environment context and reproduction steps, correlating events to pinpoint where the bug originates and what conditions precede it.

Can I use bug investigation to support incident response workflows?

Yes, structured bug investigation directly supports incident response by providing phased mitigation plans, detailed evidence, and safe escalation paths. Bug Hunter integrates reproduction, RCA, and fix verification into collaborative workflows for faster resolution and knowledge capture.

What do I need before starting a bug investigation?

Bug investigation requires user-reported symptoms, environment details (OS, versions, configuration), and any available error messages or logs. Bug Hunter accepts this initial data and guides structured troubleshooting to build a complete picture of the failure.

How do I verify that a proposed bug fix actually resolves the issue?

Fix verification involves applying the proposed change, re-executing reproduction steps, and confirming the bug no longer occurs. Bug Hunter guides this testing phase with evidence collection and validation steps, ensuring the fix addresses the root cause without introducing new issues.
