SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Perform root-cause analysis for bugs/errors/regressions using logs, repro steps, and hypothesis testing. Use when the user reports “nie działa”, stack traces, failing tests, or regressions.

Core Features & Use Cases

Structured RCA workflow: restate symptoms, collect minimal repro, generate hypotheses, test each with smallest checks, and verify fixes.
Hypothesis-driven debugging: prioritize up to three likely causes and validate with minimal experiments.
Repro-friendly guidance: clear steps to reproduce, verify, and prevent regressions.

Quick Start

Provide the observed symptom and any available logs to begin the RCA flow.

FAQPage Schema

How do I perform root-cause analysis for a software bug using logs and repro steps?▼

Root-cause analysis identifies probable software failure causes by restating symptoms, collecting minimal repro steps, generating up to three hypotheses, and testing each with minimal checks. Provide observed symptoms and logs to begin the structured workflow.

What is the best way to debug flaky tests and regressions across development pipelines?▼

Debugging flaky tests and regressions uses a hypothesis-driven approach to prioritize likely causes and validate them with minimal experiments. It applies to error messages, stack traces, and regressions across development pipelines and production environments.

Can I use hypothesis-driven debugging to diagnose stack traces and error messages?▼

Yes, hypothesis-driven debugging diagnoses stack traces and error messages by generating up to three likely root causes and validating each with the smallest possible checks. This structured RCA workflow requires access to logs and tests.

Do I need access to logs and tests to troubleshoot a bug with structured RCA?▼

Yes, structured RCA requires access to logs and tests to perform hypothesis testing. You provide the observed symptom and any available logs, then the workflow guides you through clear steps to reproduce, verify, and prevent regressions.

Why does root-cause analysis require minimal repro steps to verify fixes?▼

Root-cause analysis requires minimal repro steps to isolate variables and validate hypotheses efficiently. Clear steps to reproduce ensure accurate verification of fixes and help prevent future regressions across development pipelines and production environments.
