What is Systematic Debugging?
Guides agents through root-cause-first debugging for test failures, production bugs, performance problems, build failures, and unexpected behavior instead of guessing at fixes.
What does Systematic Debugging do?
Systematic Debugging is a Superpowers skill that enforces a root-cause-first approach to technical problems. Its defining rule is simple: do not propose a fix until the failure has been investigated with evidence. It applies this discipline to test failures, production bugs, performance issues, builds and integrations.
Who is Systematic Debugging best for?
- Developers debugging AI-generated code
- Teams dealing with repeated failed fixes
- Engineers investigating build or integration failures
- AI coding workflows where guessing creates costly rework
Common use cases
- Diagnose a failing test before editing code
- Investigate a production bug with reproducible evidence
- Trace failures across multiple system components
- Review recent changes and environmental differences before selecting a fix
How does Systematic Debugging work?
The skill follows four ordered phases beginning with root-cause investigation. It requires careful reading of errors, consistent reproduction, recent-change review and evidence gathering across components before moving toward hypotheses and fixes.
Key benefits
- Reduces random trial-and-error changes
- Keeps debugging grounded in observable evidence
- Works across bugs, tests, builds, performance and integrations
- Helps AI agents resist premature 'quick fixes'
Things to know
- A disciplined investigation can feel slower at the start than guessing
- Some production-only bugs may require additional telemetry or access before a root cause can be proven
- The workflow still depends on the investigator correctly interpreting the evidence

Sentry Issue Fixing
Investigates Sentry issues from stack traces, events, breadcrumbs, releases, and repository context, then validates a focused fix instead of guessing from the headline.
Test-Driven Development
Enforces test-first implementation for features, bug fixes, refactors, and behavior changes using a strict red-green-refactor workflow and explicit verification.
Microsoft DebugView
Uses focused diagnostics and debugging evidence to investigate application behavior, logs, failures, and runtime state without replacing root-cause analysis with speculative fixes.
Verification Before Completion
Requires fresh evidence before an agent claims work is fixed, passing, or complete, making it especially useful for validating AI-generated code before commits or pull requests.
Azure Diagnostics
Investigates Azure application and infrastructure failures using resource state, logs, metrics, configuration, and dependency evidence, then recommends scoped remediation.
Azure Validation
Validates Azure application and infrastructure readiness before deployment by checking configuration, permissions, dependencies, templates, and expected operational behavior.
