SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Frustrations from unclear failures disappear as this skill guides a structured root-cause investigation, reducing time to a durable fix.

Core Features & Use Cases

  • Four-phase debugging approach: investigate, analyze, hypothesize, implement, ensuring discipline and repeatability.
  • Tooling-aware guidance: leverages commonly available tools (Bash, Read, Write, Edit, Grep, Glob, AskUserQuestion, WebSearch) to collect evidence, search traces, and formulate hypotheses.
  • Reproduction, triage, and fix delivery: prompts for error messages, stack traces, reproduction steps, and actionable next steps to close issues reliably.

Quick Start

Describe the error and reproduction steps, then invoke investigate to begin root-cause analysis.

Frequently Asked Questions about investigate

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

FAQPage Schema
How do I find the root cause of a software crash using a stack trace?▼

Root-cause debugging uses a structured four-phase workflow to interpret stack traces and identify software failures. By guiding evidence collection and hypothesis formation, it translates raw error data into actionable fixes.

What is the best way to debug flaky behavior and performance regressions?▼

Debugging flaky behavior and performance regressions requires a disciplined investigation process across code, tests, and deployments. A structured approach enforces analysis and hypothesis validation to ensure reliable, durable fixes.

How do I start a root-cause analysis when I only have an error message?▼

Start root-cause analysis by providing the error message, stack trace, and reproduction steps. The investigation process then coordinates with logs and traces to collect evidence and formulate actionable next steps.

Can I use Bash and Grep to investigate incident logs for bug fixes?▼

Yes, incident analysis leverages Bash, Grep, Read, and other standard tools to search traces and collect evidence. This tooling-aware guidance ensures thorough investigation of logs and error data to surface root causes.

Does structured debugging work for fixing errors across deployments and tests?▼

Structured debugging applies to user reports of errors, crashes, and flaky behavior across code, tests, and deployments. It uses a four-phase process to ensure repeatability and deliver reliable fixes for complex incidents.
